Everyone loves a good mystery, right? Set your kids up to solve a mystery using the process of scientific inquiry. Students should have a little background on the steps of the scientific method and you are creating the space for them to show off their new knowledge. There are 4 options of this activity provided. You may choose a story based option or not. For each of those options, there is a data sheet with tests already designed and one for them to use if you would like them to design their own tests. This is a time to talk about what occurs in good experimental design, experimental controls, and creating reproducible results.
