Unit 2: Introduction to Matter

In this segment, our students learn about physical properties of matter using the densities of pennies as a model.

Our students continue their discussion of penny densities in this segment and begin a crushing experiment to examine the different physical properties of chemicals.

In this segment, we continue with our exploration of physical properties, including brittleness and malleability. We also learn about phase changes and observe a demonstration on the freezing point of water.

Dr. Adrian Elliott from the Fernbank Science Center joins us in this segment for a special interview, and our students discuss sublimation and deposition.

During this segment, we learn the difference between chemical and physical properties, and we see a demonstration of reactivity.

Homogeneous and heterogeneous mixtures are the focus of this segment as well as solutions and alloys.

In this segment, students learn how to separate particles from a mixture while completing a candy chromatography lab.

Our students begin this segment by discussing the results of their candy chromatography experiment. Then they’re given an engineering design challenge to further explore the process of separating solutions.

In this segment, our students discuss the results of their engineering design challenge and we hear from special guest Stan Brinkley, with the Cobb County Marietta Water Authority.
