Molecules and Water

Moving Molecules
Science Demonstrate how heat energy affects the movement of molecules by filling two identical, clear glasses with the same amount of water. Use cold water in one glass and hot in the other. Add two drops of food coloring to each glass. Observe how quickly the color spreads throughout. Which water colors faster, cold or hot? What does this tell us about how heat affects the molecule movement?

The Movement of Liquid Molecules
Students will observe food colouring being diluted in hot, room temperature, and cold water. Through this activity they will be able to visualize and better understand the concept of the constant motion of molecules.

Hot Colors
This experiment looks at the affect of temperature on the speed of molecules in water.

Atoms and Molecules
Students will learn that matter is made of atoms, that an atom is made of protons, neutrons and electrons, the charge of each particle, and how they are arranged to make up an atom. This lesson also includes the definition of a molecule, an element and a compound.
