I need a lab idea
I teach 8th grade science. We are doing a lab showing a chemical reaction with backing soda, calicum carbonate, and pH indicator. It was a fun lab that showed a chemical reaction with color change and temperature change. The kids LOVED it. Now I want to do a lab that shows precipitate forming from a chemical reaction. I want to do this because my kids are having a hard time wrapping their heads around the fact that two liquids can form a solid. Does anyone have any lab ideas? Funding is tight at this title one school that is spending all of their funds in math and reading. So, any ideas?
