Kit Information

Grade: 5
Type: Physical Science
Description:
In this unit, students are introduced to the basics of chemical analysis by exploring the properties of five common "mystery" powders. Students mix water, iodine, cabbage juice, and other liquids with the "mystery powders", and they observe and record changes that occur. Other hands-on activities include testing for solubility, experimenting with filtration and evaporation, and testing the powders further by exposing them to heat. The topic of "bases and acids" is also introduced when red cabbage juice or litmus paper is used as a pH indicator. Once the students are able to identify the powders, they are able to mix some of them and then identify component parts of the combinations.
