This lesson brings to life the amazing physical changes that are going on around us every day. With reference to previous lessons you will explore how substances behave differently as they change states (gas, liquid, solid).

While covalent compounds, also called molecular compounds, only consist of the 16 non-metals you see on the right side of the periodic table, they make up the most diverse and flexible types of interactions. Now in this film, you will focus on molecular bonds and the compounds they form. You will learn the role that shape plays in determining the chemical and physically properties of molecules and the compounds they form, why they are so flexible...

This film provides a wonderful introduction to why organic compounds play such an integral role in our bodies and the world around us. You will learn how to identify organic compounds, the role carbon plays in the amazing diversity of organic compounds, as well as further emphasis on why shape matters so much in chemistry.

This film provides a real-world look at the role of mixtures and solutions in our lives. You will begin by exploring the different types of mixtures and their characteristics. Then you will move on to learn about a special type of mixture called a solution. Although you have heard the term solution many times before, you will be surprised by how prominent solutions are in society and the many forms they take. You will explore real-world examples of...
