Lab-Aids: Kitchen Chemistry Kit - Bilingual English/Spanish
This fun activity emphasizes experimental observation and scientific reasoning skills. 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 to complete the activities are included in this kit. This kit is complete for 50 students.
