Description
Grades 9–12.
- Investigate intensive and extensive properties
- Explore differences between chemical and physical changes
- Classify samples as elements, compounds, and mixtures
Students study the classification of matter, intensive and extensive properties, and chemical and physical properties and changes. As a final activity, students use their knowledge to design and conduct an experiment based on the relationship between intensive and extensive properties, focusing specifically on density.
Kit includes lab supplies (samples of elements, compounds, and mixtures as well as materials to perform several experiments demonstrating physical and chemical changes—enough for at least 30 students working in groups of 3) plus teacher’s manual.
Kit Refill replenishes consumed materials.
