Physical and Chemical Changes and Properties
8.MS-PS1-2. Analyze and interpret data on the properties of substances before and after the substances interact to determine if a chemical reaction has occurred.
8.MS-PS1-5. Use a model to explain that atoms are rearranged during a chemical reaction to form new substances with new properties. Explain that the atoms present in the reactants are all present in the products and thus the total number of atoms is conserved.

Electrolysis of Water Lab
On the right is the result of testing for the presence of Hydrogen in Mr. Heim's class with a flaming splint. As you can see we had quite an explosion here. Did you wear your safety goggles today? Notice the test tube is upside down. Why? |
