Grades 6-10. The focus of Experimenting with Mixtures, Compounds, and Elements is to build students' understanding of the physical and chemical properties that distinguish these 3 types of matter. This Student eGuide allows students and teachers 24/7 access to their STC-Secondary content for this unit. Access for 32 students per year for 60 months.

Grades 6-10. The focus of Experimenting with Mixtures, Compounds, and Elements is to build an understanding of the physical and chemical properties that distinguish these 3 types of matter. In this unit, students investigate how such properties can be used to separate mixtures or how additional energy (in the form of heat or electricity) is needed to separate compounds. They examine elements and discover that elements can combine to form compounds but cannot be further separated into different components.
