1. Experiment 1: Melting Ice Demonstration

3. What happens when the ice melts?

• The ice grows bigger

• The water disappears

• The water level goes up

1. Experiment 1: Melting Ice Demonstration

3. Why does ice melt?

• It is cold

• It is heated

• It is in the dark

1. Experiment 1: Melting Ice Demonstration

3. What does melting ice show us?

• Earth is cooling down

• Earth is getting warmer

• Water is freezing

1. Experiment 1: Melting Ice Demonstration

3. What happens if Earth gets hotter?

• More ice melts

• Ice freezes faster

• Water becomes solid

Experiment 2: Heat Capacity Demonstration

6. What is tested in Experiment 2?

• How balloons fly

• How water and air absorb heat

• How water boils

Experiment 2: Heat Capacity Demonstration

6. Which balloon gets hotter?

• The balloon with air

• The balloon with water

• Both balloons

Experiment 2: Heat Capacity Demonstration

6. Why does the water balloon get hotter?

• Water absorbs heat

• Air absorbs heat

• Water stays cool

Experiment 2: Heat Capacity Demonstration

6. What happens when the water balloon is heated?

• The water gets cooler

• The water becomes ice

• The water gets hotter and changes

Experiment 2: Heat Capacity Demonstration

6. What does this experiment show?

• Greenhouse gases trap heat

• Heat helps balloons float

• Water freezes quickly
