How Do Common Household Chemicals React?
- Emphasize experimental design and observation
- Develop scientific reasoning skills
- Kit requires one ~50 minute class period to complete
The primary purpose of this Lab-Aid is not to identify the common kitchen chemicals, but to observe how they react. Students first explore some physical and chemical properties of several common kitchen substances (four powders). Then, they determine some properties of the powders by using three liquid indicators. After determining the physical and chemical properties, students attempt to identify some of the mystery powders provided using the results from their experimental observation. The solutions and powders necessary for up to 50 students to complete the activities are included in this kit.
