We had a visitor come to our school to give a presentation to all the fifth grade classes. The presentation was about chemicals, acids, bases, and mixers.
We learned that if you mix acid with the same amount of base you will get a neutral chemical. There are many chemicals that we have in our kitchens like baking soda, vinegar, sprite, and cabbage juice.
We tested different chemicals on a coffee filter that was soaked in cabbage juice. We had to solve the three mystery unknowns.
At the end of class every group got a jar of vinegar and we put pennies in the jar and shook it for the penny to get cleaner. We shook the pennies for 30 seconds each. It was amazing how quick it worked.
Chemistry is so much fun. Thanks Acton Discovery Museum!
