Importance of Compost Piling by Sophia
Have you ever wondered what the importance and
benefits of composting is? Composting is basically just making a pile or heap
of green waste and stirring it until it is broken down. Green waste is simply
wetted down organic matter, such as leaves and food waste. Green waste normally
breaks down after a course of weeks but can also take as long as months to
break down. Compost is a key ingredient to organic farming.
There are many cool and unique ways to compost
food waste. After it breaks down it is recycled and used as fertilizer and soil
amendment. Compost waste is rich in nutrients which it is so good to use for
plant growth.
You can use one of many ways to create a compost
at the comfort of your own home. There are many composting benefits, like introducing
beneficial organisms to soil, it’s good for the environment, and it reduces
landfill waste. You can compost materials like animal manure, table scraps,
paper, and even wood chips. There are multitudes of organisms, fungus and
bacteria involved in the process of composting.
In composting, you will want green materials like
lawn and landscape trimmings to reduces the amount of nitrogen. More green
materials like fruit and vegetable peels would work great. Tea bags and coffee
grounds are brown but are just as potent as green materials when it comes to
nitrogen. For carbon, you’d want brown materials such as twigs, hay, and dry
leaves.
You’ll definitely want to keep water around the
compost pile to keep it moist. A compost pile needs oxygen to keep the bacteria
and fungus in the compost pile alive. You can add worms in the pile, and bugs
will find their way there.
When starting a compost pile, you want a certain
amount of soil and scraps in your pile, this gives enough insulation and food
for the organisms to live. For kitchen biology, we created two compost piles
consisting of the same amount of vegetable and soil, and watered with the same
amount of water but one was vermicomposting. The process was slow at first but
towards the end, sped up and eventually showed progress. It was a great
experience.

Nanotechnology by Richard
Summary:
Nanotechnology
is technology that is less than 100 nanometers wide. It can help with lots of
different types of stuff. It helps with medicine, solar cells, batteries, food,
fuel cells, and better air quality. If
it is breathed in it can damage your lung tissue and can cause chronic
breathing problems. If it gets into your bloodstream it can kill you.
What I found most interesting about the topic:
What I found most interesting about the topic is that it can
help bring the taste in food out more.
Three interesting facts that I learned:
1. It can help with better air quality because it can
transform the vapors that come out of cars and factories into harmless gases.
2. If it gets into your bloodstream it can kill you.
3. It is used to
bring the taste in food out more.
Question:
Why do you think nanotechnology is harmful to us?
Soil by Mikayla
Soil is the “natural medium of growth and land”. Soil is very
important to our world whether we realize it or not. It helps grow the things
we need and has been used forever.
There are three types of soil; clay, sand and silt. Clay is
the smallest soil particle there is. Sand is the largest particle, and silt is
right in the middle. In each types of these soils there are different layers.
The first layer is topsoil, which is the upper part. The second layer is
subsoil, which is right below topsoil and has clay that is more compact. The
very last layer is bedrock, this is the hard rock beneath the surface
I find it
very interesting that certain crops grow in the certain types of soil. For
example in light textured soil, things such as vegetables and corn can grow.
But in loamy soil almost everything can grow good in it. I also find it amazing
that the more structured the soi is, the better plants grow in it. For example
structured soil allows more water intake, so plants do better with this soil.
The last thing that I find most interesting is that if you want to fix soil so
it has better qualities, you just need to leave it alone - it will fix itself.
I would have thought that you would need to do a ton of things to it.
My question to everyone is how can
you help improve the soil?
The Nutrient Cycles By Arissa
The nutrient cycles are a crucial part in all ecosystems,
they are responsible for the reuse of water, energy, and food. All life relies
on three main cycles, the carbon cycle, nitrogen cycle, and water cycle.
Starting with the carbon cycle, carbon has the most
important part to play in all of the ecosystems. Throughout the course of the
carbon cycle plants extract carbon dioxide from the atmosphere, then perform
photosynthesis, animals consume the plants and replace the carbon dioxide
through breathing. This process is also responsible for providing energy for
factories, trains, planes, and cars in the form of fossil fuel. This is a
constant cycle, to bring us back to the beginning, after the death of an animal,
fungi and bacteria break down the organic matter and allow the growth of
plants.
Much
like carbon, nitrogen is equally important to all ecosystems. Although nitrogen
is present in our atmosphere it’s supply is limited. Nitrogen-fixing bacteria
are made to transform nitrogen into ammonia. These bacteria bring the converted
nitrogen into the water and soil for the plants. Plants then acquire the
nitrogen in the form of ammonia.
The
water cycle is what life relies on, it consists of three main parts, evaporation
(transpiration), condensation, and precipitation. Evaporation is the extraction of water from
bodies of water heated up by the sun, creating water vapor or clouds.
Transpiration is process in which plants soak up water through their roots then
the water evaporates as plants release water through small pores. Condensation
is the collection of water in the air, after condensation comes precipitation.
Precipitation comes in the form of rain, sleet, snow, and hail which falls to
the ground bringing us back to the beginning.
These
three cycles are what is keeping us alive, they are crucial to all ecosystems
and environments. Food, water, and energy are all a part of these cycles.

Composting by Lydia
Composting is when organic material
gets decomposed and then is used as a method of recycling or a way for people
to help people increase their soil fertility. There are many different methods
of compositing. You can have pile composting, open bin composting, or closed
bin composting. These are just some of the many ways of composting. This is
method that a lot of people enjoy because there is little to no cost and the
boost in your gardens fertilization is mind blowing.
- How many different kinds of compost
total do you think there are?
Something that I find interesting
about my topic is that all different kinds of organic food can change
everything about it and become dirt.
1. Composting saves money and is helping
the world stay in better shape.
2. It improves everything about the soil
and the way plants grow in it.
3. The nutrients in the soil can almost
double when we use these composite materials.

GENETICS by Sophia
Genetics is the study of heredity. In
living organisms, there are genes, genetic variation, and heredity. The main
idea of genetics being the study of heredity is that we observe that just about
all living things inherit traits from both parents. The work of Gregor Mendel
is what sparked the understanding of this process. This started in the mid-19th
century and is still a huge subject of discussion.
Gregor Mendel was a scientist who
studied the nature of inheritance in plants. For his work, Mendel traced
inheritance patterns of traits in peas. After tracing this, he would describe
them mathematically. Mendel concluded through this study that inheritance of
many traits could be explained through rules and simple ratios. Very few people
understood the concept of heredity until after Mendel’s death, when other
scientists took on studies similar to his.
With genetics comes gene mutations.
Gene mutations are alterations in the DNA sequence that is permanent. DNA
sequences are what makes up a gene. Mutations range is size and can affect
anything from a base pair to a large chromosome segment that includes multiple
genes. Many children are born with gene mutations, like Sickle-Cell Anemia and
Tay-Sachs disease. That’s just part of life.
Idaho’s State Flower, the Syringa by Joe
INTRODUCTION
The syringa (philadelphus lewisii) has been the state flower
of Idaho since 1931, and was an obvious choice for the position due to its
beauty and importance to the Native American as a means of creating tools. It
grows on a shrub that can reach almost ten feet in height, with flowers growing
in clusters on the ends of long stems. The wooded part of the shrub provided
wood that the Native Americans used to create harpoons, bows, arrows, and
numerous other tools requiring a wooden shaft. It is fascinating that an
aromatic and aesthetically pleasing object would also be necessary for some
cultures to hunt and forage for food.
INTERESTING FACTS
ABOUT SYRINGAS
1.
The flower is named after Meriwether Lewis, as he was
the first to collect and publish about it.
2.
The bark and leaves can be used to make a soap.
3.
Quail, deer, and elk are known to forage syringa.
QUESTION
How was syringa an integral part of the pioneering Native
American tribes?

Light bulbs by Triston
Light bulbs can be put into anything
that produces an electric charge, like a lantern or a flashlight if your are
going camping, or if you need to go somewhere that doesn't have a light in the
room. They go on the front of your car, and the back of it. They can go on any
motor vehicle that you want you just need the extra parts. There are are
different types of light bulbs like LED lights and there are incandescent, and
CFL bulbs
Does temperature impact performance
of a light bulb?
I find this
topic interesting because i might just buy LED lights because they last for 20
years with just one bulb.
Three neat facts about light bulbs
are that the first light bulb that was ever invented was made in 1802 by
Humphrey Devy. Halogen light bulbs were first produced in the 1950s. Another
neat fact is that it takes 6 billion electrons to light up one 100-watt bulb
for only one second.
Main Plant Parts By Brooklyn
Plants play huge roles in our lives
and on our planet. Without them, there is no us. They provide us with the
oxygen we need to survive. With plants being very important pieces in our
society, how do we not know more about them? Very few people have knowledge
about plants and their anatomy.
There are
four main parts of plants. There are roots, leaves, flowers, and stems. All are
extremely important to the plant and help it survive.
Roots are the thin branches on the
bottom of the plant that help anchor it. They also store food and absorb water.
There are two different types of roots, tap and fibrous. A tap root is one main
root, it is usually very hard to pull (for example a carrot). Fibrous roots are
many little roots that branch out and all play an equal role. They do not go
very deep.
Stems help determine the plant’s size
and position. They move the leaves in
order to get sunlight so the plant can photosynthesize. The xylem is the center
of the stem, it moves the water from the roots to the leaves. The phloem is
outside of the xylem and moves sugars down from the leaves to the roots so it
can be stored.
Leaves
make food for the plants through photosynthesis. They collect the sun’s light
and use it to make energy that the plant uses as food. Monocots are plants with
straight-veined leaves. For example, palm trees are monocots. Dicots are plants
with puzzle-veined leaves. The leaves branch out all over the place and have no
particular pattern. For example, a maple is a dicot.
Last,
but not least, are the flowers. These help the plant reproduce. The stamen of
the flower has pollen on it which is transferred to other flower’s stigma by insects.
The more you know, the better off you
are! Plants help us in so many ways and we should really take the time to learn
more about them. Here’s my question for you: Which part of the plant is the
most important, and why?
DNA by Jacob
DNA controls the cell when the DNA
in a gene is changed. The change can cause the cell to behave differently.
Some mutations happen as a mistake
spontaneously by a factor of the environment called a mutagen that has
radiation, chemicals, and high temperatures. Asbestos was a used chemical by
humans and many died because of it.They interact with the DNA molecule and
cause changes.
Some mutations are bad but some can
be good a lot of times such as the American Wirehair cat which the mutation had
no harmful effect.
Are mutations sometimes good for
people and animals?
What I find
most interesting is that the Wirehair cat mutation happened and that it had no
harmful effect on it.
1.)
Mutations can be sometimes caused by errors,
transcription, cell division, or external agents.
2.)
The cells grow and divide very quickly to make cancer.
3.)
Chromosomal mutations are common in plants.
Substances and mixtures by Asher
Substances and Mixtures
Matter consists of two broken down categories, mixtures and
substances. A mixture is created by mixing two or more substances together. A
substance has one atom type or a molecule. There are two types of mixtures,
heterogeneous and homogenous. Heterogeneous mixtures have two or more
distinguished mixed substances and do not have a fixed ratio, and homogeneous
mixtures have the same amount mixed every time and are mixed thoroughly
throughout the mixture.
When you measure a substance the boiling point and melting
point are constant because a substance has a fixed ratio. Substances contain
both compounds and elements. Elements are the building blocks of matter and
compounds contain two or more elements within them.
The most interesting thing to me is
that I can look at the world and identify if a certain object has different
properties than another just by looking at them.
Fun Facts:
A substance has a fixed composition.
A mixture can be separated into its
components.
No matter can be created or
destroyed, only transformed.
Next time you eat a meal ask
yourself, what kind of matter am I eating?

Beavers by Abi
Beavers are
the second biggest rodents in the world. When you see the dams in rivers or
ponds, that is because of the beavers. Beavers help our landscape. They have
been around for a long time. They are family oriented and normally mate for
life, which consists of about fifteen years.
What I find most interesting about this topic is that the beavers have
coarse hair on their back and soft hair on the stomach. The coarse hair acts a
waterproof coat.
Beavers are
very interesting. They have scent glands that extract a vanilla scent. You
should respect a beaver’s boundaries, because they are protective. Also
beaver’s teeth never stop growing.
Ask yourself
this…. Are you cleaning the environment to help your beavers continue to fix
the landscape?

Avocado or Avogadro? By: Sydney
This week
in Chemistry, we have been learning about the differences and similarities
between formula and molecular weight as well as how to calculate molar mass. To
fully understand the work we have been doing, it is first important to know the
terms we are working with.
Formula
Weight is the sum of the atomic weights of the atoms in the chemical formula of
the substance.
Molecular
Weight is the same as the formula weight when the chemical formulas between the
two are the same.
In order to calculate the formula weight, it is necessary to
find the atomic weight of each element. This is found above the element symbol
on the periodic table.
With that in mind, we need to determine how many atoms of
each element there are in the formula. For example, if we have the formula C17H19NO3
, we can see that the subscript tells us there are 17 atoms of Carbon, 19 atoms
of Hydrogen, 1 atom of Nitrogen, and 3 atoms of Oxygen. Now we can combine the
information we have. Basically, we are going to multiply the number of atoms
and the atomic weight of each element, then we will add all the atomic masses
together to get one number as the total average atomic mass of the formula.
C17H19NO3
27(12)+19(1)+14+3(16) = 285 amu
And voila! That is how we find the formula or molecular
weight of a chemical formula.
Next, we will go over molar mass. Molar mass is the mass in
grams of one mole of a substance. When working with molar mass, we use
Avogadro’s number. Amedeo Avogadro was a physicist who was best known for his
contribution to molecular theory. Personally, I think he looks kind of like a
bird!
To find it, we use Avogadro’s number.
6.022 x 1023
When you have grams that you want to translate to moles,
they are the same numbers but they are labeled with different units of
measurement.
16 grams = 16 moles
Regarding the information we have been studying this week, I
think it is interesting that after using Avogadro’s number, the numbers are the
same, yet the units of measurement are different. This must make it fairly easy
when working with molar mass!
Here are some interesting facts:
Avogadro’s
full name is Lorenzo Romano Amedeo Carlo Avogadro di Quaregna e di Cerreto…
that’s a really long name!
Avogadro’s
number is abbreviated as NA.
There are
only a little over 100 types of atoms!
Lastly, my question for the audience is, do you think
Avogadro looks like a bird?
Digestion by Luke
In the Advanced Biology class, our
class is learning about the digestion system. There are three different types
of digestive systems. Herbivores it plants and carnivores eat meat. Also,
omnivores eat both such as humans. All vertebrates have one-way digestive
tracts, they typically begin in the mouth and end in the anus.
The mouth is the first step of the process. The mouth breaks
down food using teeth and saliva. The saliva serves as a lubricant for food so
it can pass through the esophagus easily, and the esophagus connects the mouth
to the stomach. The stomach is a sac-like structure that stores food that is
waiting to be digested and it churns food with the help of HCl. The processed
food, called chyme, leaves the stomach through the pyloric sphincter into the
small intestine. While in the small intestine enzymes created by the pancreas
continues to break down food into useful nutrients like carbohydrates and
protein. After it passes through the small intestine, the large intestine
compacts the waste products into feces so it can pass through the anus. Overall
the digestion system is used to break down food into useful nutrients that our
bodies need, but how long does it take humans to completely digest a piece of
food?
Interesting
Facts
1. The small intestine in humans is
about 23 feet (7 meters) long.
2. Herbivores have large divided
stomachs called ruminants.
3. Hydra worms have two way digestive tracts.
Cells by Santi
This week is biology we are learning about cells and the
cell cycle. The main difference between animal and plant cells is that plant
cells contain vacuoles, a cell wall, and chloroplasts.
Plant cells get their energy from sunlight, this process is
called photosynthesis. The chloroplasts are what controls photosynthesis. These
chloroplasts contain chlorophyll, which is what captures and absorbs the
sunlight.
The cell wall in plant cells is made out of cellulose and
adds more protection and stabilization to the cell.
The vacuoles main function is to control what comes in and
out of a cell. They are also used for storing nutrients.
3 fun facts: All living things are made up of cells. Groups
of cells can make tissues and organelle systems. Even the largest cell, is
still too small to be seen with the human eye..
My question for y’all is what do you know or like about
cells?

Should we use Microwaves to cook our food? By:Kiahna
I believe that using a microwave is not bad. The Microwave
has a electric tube called a magnetron. It produces electromagnetic
radiation. The Magnetron inside the oven
changes regular electric power from a wall socket into super short radio waves.
They are about four inches from crest to crest. They are made when the
microwave's magnetron is at a frequency of 2450 megahertz. When something gets to that frequency the power is
absorbed and absorbed by water, fats,
and sugars, that become very fast
vibrations and high temperatures that cook the food.
Microwave ovens
heat food by making radiation which is caused by the water molecules
being absorbed. It makes the water molecules vibrate and makes
heat and then cooks the food. Almost all ovens that are made recently are safe to use as long as you
follow the instructions. Almost everyone has a microwave, some people think
that cooking food in a microwave can
harm you. They think that it gets rid of all the nutrients.
Microwaves do spill out some radiation, but
that is the same as using a cordless phone, cellphone, laptop. They turn on and
off like a lightbulb. It does make radiation waves so when it is on it is
better to stand away. When the microwave is off the waves can’t emit. They also
can’t flow around in the oven and get
into the food.
It is actually better to cook your vegetables
in the microwave because it cooks them fast and it doesn’t use as much as water
as steaming does. Using a microwave is very helpful but you need to use
microwave safe containers. Microwaves will kill bacteria when a food is
cooking, microwaving is safe.
Evolution by Darell
Evolution is the change in species over time. Evolution must
have a competition for survival, mutations, and reproducing organisms. This is
important because it take variation to later develop into evolution and natural
selection is where this variation comes from.
Natural Selection is the survival
of the fittest. This means the most adapted or the organisms that are best fit,
survive and pass on their genes to produce offspring with that same favored
trait. After time this becomes a larger change and eventually a new species is
created. The other way this can happen is through mutations, a simple favored
mutation that is accepted and passed on can lead to a new species much faster
through the same process. Because of
evolution, we have a variation in species and we are able to have diverse
amount of organisms. People often debate whether or not evolution is a real or
if it should be accepted by society. There is a large amount of proof to back
this idea up. First is biochemistry, this shows that different species have
common DNA and scientist are able to prove the relatedness of species based on
that. Homology is another solid piece of evidence that goes to show that
species originate from one another, the best example has to do with whales and
bats. Humans have a arm/hand structure that is very specific, and yet whales
and bats share that same structure. Although they are used for different
things, they show that they developed from a similar being.
Charles Darwin was the first to recognize and
attempt to understand this process. He visited the galapagos islands and
observed all the different types of finches and the different beaks they had.
He began to realize that the beak shape, size, etc had a direct correlation
with the habitat in which they lived. This intrigued him and he later founded
his idea of “Evolution”. I find it interesting that organisms are able to
develop overtime and change even though there is no “answer” to how the changes
occur. I also find it interesting that birds that are so closely related and
live in only slightly different environments would change overtime like that to
develop different beaks and why this process was not discovered before. What do
you think is the most important part of evolution?
Causes of Cancer By: Rachael
Cancer is a medical issue that most people worry about but
not a lot of people actually know the causes of cancer. I've always been
interested in cancer and how exactly the cancer cells get abnormalities. Cancer
begins in a single cell that normally didn't go through mitosis properly.
Scientists have found that most cells that went too quickly through the mitosis
process didn't have checkpoints in the cell. These checkpoints allow the cell
to go through mitosis at the right speed, but if a cell doesn't have these it
rushes through everything which creates abnormalities.
These abnormalities will create a cancer cell which keeps
replicating forming more and more. These cancer cells will come together to
form a tumor. Tumors are masses of cells which interfere with normal cells.
They suck energy and things like that which they need and that causes other
healthy cells to suffer from not getting what they need. These tumors can
normally be cut out or some other form of treatment but it is best if it is
caught in the early stages. An interesting fact is the different kinds of
cancer are normally named after the body part that the tumor is in. So the name
making process isn’t as creative as you think it is.
Metastasis is when a cancer cell breaks away from the tumor
and travels to other locations, infecting them. This causes cancer in multiple
places which is why you hear stories of people with multiple kinds of cancer.
Once you get cancer in multiple places it is very hard to treat and dangerous
for your body. Another interesting fact about metastasis is in the naming of
the new cancer. Say you have breast cancer and metastasis happens and it
travels to your lung it would then be called metastasis breast cancer not lung
cancer. The name of your new cancer is the same as the old one, just with
metastasis added to the front of it.
Two different causes of cancer are genetic or environmental.
You could have it in your genes and something triggers it or you might get it
from an environmental factor. Some direct causes of cancer are UV radiation
exposure, smoking, your diet, air pollution, and viruses. An interesting fact
about environmental factors is if you move to a country with a different cancer
rate than your previous country then your cancer rate will change. A prevention
tip is just trying to live a overall healthy lifestyle. Exercising daily, no
tobacco use, and a high fiber diet are all ways to help you live a healthier
life.
Questions:
What are
some things in your diet that might be linked to causing cancer?
What are
some different types of cancer you could develop?

Chemical Reactions by Luke
Currently, the Garden Valley Chemistry
Class is learning about chemical reactions between molecules and bonds. The
class is learning about four different chemical reactions, but are there more
types of chemical reactions in our world? The first type of chemical reaction
is named single replacement, this is when one element replaces another element
in a compound. The second type is called a double replacement reaction. This is
when two compounds switch their cation and anion. The third reaction is called
synthesis. This occurs when two elements combine to create one product.
Finally, decomposition is the last type of chemical reaction. This is when a
compound breaks down to create two or more elements.
Interesting Facts About Chemical Reactions:
1. Melting or freezing water is
not a chemical reaction. This is because it stays as H2O
2. When one reaction causes
several reaction, it is called a chain reaction
3. One cell causes 100,000,000
chemical reactions per second in the mitochondria
I find it interesting that all chemical
reactions are directly related to molecules forming and breaking down, it’s
also scientist can link a specific chemical reaction to the composition of
molecules.
Evolution by Darwin and Wallace by Molly
Think about
this.
I'm going to explain the work that
darwin and wallace both did, who do you think did the most work? Who deserves
the credit for evolution?
Charles Darwin
● He was a naturalist
● Second youngest out of 6 kids
● Came from a long line of scientist
●
Grew
up wealthy
● Had lots of schooling
Alfred Russel Wallace
● Naturalist
● Not very educated more self taught
● He didn't grow up in a wealthy family
●
Did
things on his own
More on Darwin
Darwin and his mentor went on a 5
year voyage that was going to send them around the world.
Darwin collected specimens from all
around
The galapagos islands are what stuck
out most to darwin.
When he got home we was looking over
his finding and came up the the theory of evolution. (finches)
More about Wallace
He went on an 8 year expedition in
indonesia
He gathered over 100,000 animal bird
and insect specimen
As soon as wallace figured out
exactly how evolution he wrote it down on a 8-9 page paper, he sent it to
darwin for a peer review.
In an earlier year wallace was bringing back superman and his
boat caught fire.
Together
Darwin and wallace came to the same
conclusion about evolution.
They published a paper together on
evolution.
Darwin published a book on the origin of species and wallace
faded away.
My opinion
I find it interesting how they tried to do this together and
it ended up being darwin taking a lot of the credit and wallace just stayed
quiet while continuing his research.

Mushrooms by Bryce
This week we learned about Fungi and Mushrooms.I learned
that most mushrooms with gills on them are poisonous.
I also found out that most of the poisonous mushrooms are
identical twins to edible ones which cause them to be easily misplaced.
The difference between a fake moral and a real moral is that
the cap is connected to the stem of a real moral where in a fake moral has the
top just kinda placed on there.
I also learned that black holes can throw planet sized rocks
really fast out of them like a spitball...luckily they are millions of
lightyears away but it’s still kinda scary.
It is amazing how crazy everything around us is and the best
part is that we don’t even notice it most of the time...Just ponder on that and
just take a look around you and just imagine what a person had to think to
invent something or the first time that we studied a certain thing.
The Rules of Binary Covalent Nomenclature by Caitlin
Binary covalent compounds are
composed of two different elements, typically non-metals. It is important in
the scientific community to know how to correctly name these compounds. There
are four main rules to follow in order to piece together the name of a binary
covalent compound.
Rule #1:The first element keeps its
name.
Rule #2:The first element only gets a
prefix if it has a subscript in the formula.
Rule #3: The second element gets the
suffix -ide.
Rule #4:The second element always gets
a prefix.

●
When there are two vowels adjacent to one another, the
end of the Greek prefix is usually dropped.
●
When the compound contains a oxygen and a halogen, the
