Lesson Planning

Teaching

• Understand that water is a material and ice is water in a different state.
• Consider the questions: how does the appearance of ice change as it melts? How long will the block of ice last? What will happen if we put salt on it?
• Record observations and make predictions.
• Understand what happens to particles in ice and water by role-playing the movement of particles in the PE hall/playground.

Activities

1. Understand that water is a material and ice is water in a different state.
2. Observe and record the changes to a block of ice.
3. Begin to understand that what happens to particles in ice when it starts to melt and turn to water.

Investigation - exploring, problem solving, observing over time
Observe a block of ice and record the changes.
Devise an investigation to melt the ice quickly or slowly.
