The heat is on!
Yuck! We drink water that is billions of years old! Where does the water on Earth come from? How is it transformed? Young minds learn about the water-cycle stages, its scarcity, composition, origin and boiling temperature through fun, little science experiments that will turn them into true chemists and show them how to safely make a small storm inside a test tube heated by a burner!
For 30 more minutes:
Add another amazing experiment using the burner to learn about the effect of pressure on the boiling of water.
Objectives at the elementary level:
- Describe where Earth’s water comes from.
- Describe the different stages of the water cycle (evaporation, condensation, precipitation, runoff and infiltration).
- Identify natural freshwater sources (streams, lakes and rivers) and natural sources of salt water (seas and oceans).
- Experiment how atmospheric pressure acts on water (compression, displacement, temperature increase).
- A sink must be available close to the classes where the animation activity will take place.
- If there isn’t much time between animation activities, it is strongly recommended that they are set up in the same area.
- 6 teams must be formed before the science animator arrives.
