Foundation: Dissolving, Color, and Separation

Before You Begin: The Shape of This Phase

Does It Disappear?

Check Your Understanding: Dissolving

Colors on the Move

Check Your Understanding: The Milk Explosion

Oil and Water Don't Mix

Check Your Understanding: The Persistent Separation

Lessons 1–3: children discover that some things dissolve and some don't, watch colors move and explode in milk, and fight oil and water to a draw.

The foundation phase: children discover that dissolving isn't disappearing, that colors move and combine, and that oil and water refuse to stay mixed no matter how hard you shake them.
