Students will identify unknown chemicals based on laboratory testing of their physical and chemical properties. Students will identify the 4 different kinds of bonds that exist in chemicals: ionic, polar covalent, nonpolar covalent and metallic. Students review the properties of each solid using various tests. The activity contains enough materials for 15 groups of students as well as a Teacher’s Guide and Student Study Guide Copymasters. Meets Big Idea 2, Investigation 6, Primary Learning Objective 2.22.
