Why Lesson Planet?
First-time physical scientists explore chemical change with three activities. They combine calcium chloride with water, fertilizer with water, and baking soda with copper sulfate. For each, they describe what happens and write down the products. A worksheet and informative teacher notes are provided, but be aware that there is no answer key. Run through the experiments on your own beforehand so that you know what to expect.
