Understand tidal and wave energy and how it works
Key Words
Tidal energy, tidal barrage, dam, turbines, pressure, force, gravity, renewable, wave machine, acetate,
Resources
TIDAL = Two 2-litre plastic drinks bottles, strong cloth tape, a pair of sharp compasses
WAVE = Plastic tubes or wooden dowelling, OHT, acetate, elastic bands, plasticine, scissors
Recap what students can remember from lesson 2 about what they found out about Tidal and Wave Power. If you are struggling to remember look at the information pages in your energy project book.
Teacher will demonstrate how the tidal and wave power models work.
TIDAL
The greater mass (or weight) of water in the full bottle exerts a greater downward force (due to gravity) and so there is increased pressure on the water, pushing it out of the small hole with more force.
Red Draw a diagram of the two demonstrations that you saw.
Amber Draw a diagram of the two demonstrations that you saw and label it
Green Draw a diagram of the two demonstrations that you saw and try to explain how each model works, (you may need help from your group teacher.)
