Chemical change happens when the molecules in a substance break apart and form something new. There are five signs that a chemical change has occurred. Today we found out that one of those signs is the production of a gas.
Ask your student the name of the tiny particles that make up matter. (molecules)
Ask your child to describe what happened when we combined baking soda and vinegar.
Ask them if they observed a physical change or chemical change.
We have completed our 3 labs on matter. Next up is a special lab that ties into Halloween. It you have any spare pumpkins, we need them in all sizes. Drop me note to tracey AT ananmalay DOT com if you have some to spare.
