Combining and Separating

In this section, you will learn that different particles combine in different ways. There are mixtures, solutions, and even chemical reactions. Some of these combinations can be reversed, while some of them cannot. It will make the most sense if you watch both video lessons before starting on the experiments & activities. Watch them both back to back, or split them up if you want!

What you’ll learn:

• How different particles interact with each other in different ways.
