I love this activity for teaching chemical changes. It shows 3 out of the 4 indications that a chemical change has taken place, the chemicals are easy to buy/store, and the clean-up is so simple! I have used this activity in both middle and high school and have never once failed to have my students amazed at the changes they observe and record.
I keep my materials for this lab together in a kit of sorts so that all I have to do from year-to-year is replace the consumable materials and IÃ¢ï¿½ï¿½m ready to go the next year. Below you will find a material list (with pictures, as always!) and then a set-up and lesson plan area. This is where I tell you exactly how I use this activity with my own students. I have also included the lab sheet that I pass out to my students to record their observations and answer questions on.
Other items in my store that go along with this lab activity include:
