Experiment, by Marty

My Topic is about putting three penny’s in three beakers of of acid.

1. If you put three penny’s in the acids the acids will change the color of the penny’s.

2. The acids also clean the penny’s like you've never seen them clean before.

3. Some acids could eat the metal.

4. How does acid affect metal?

5. The Topic is important because we should all know about how acids can change the color of the penny’s and how they can also clean the penny’s.   

The things that we have been doing in science is our final assignment. The final assignment is to choose our experiments and to do them in class.
