Lesson title: Renewable energy
Class: 10Phy Date: 3rd Nov Period: 2 No. Pupils: 30 Boys: 14 Girls:16
Lesson Objectives (WALT):
Will know how we can generate energy from wind, water, solar and geothermal
Will know the advantages and disadvantages of both.
Time Activity Content / Notes (key points, questions to ask, assessment of learning, safety)
Before Have all the equipment where needed.
9.47 Starter 10 Meaning of renewable & non-renewable. Then Demo wind turbine using fan, lamp &
mins vacuum cleaner, with hydroelectric is the same only the water moves the turbine
instead of the wind.
9.57 Main Questions from 40-43 (10 mins)
activity 1 The sun delivers enough energy in 1 hour to supply our energy needs for 1
30 mins year…so why isn’t it used? When is it used? The methods we use for solar
energy as very very inefficient at present.
Geothermal is another method when the heat from the radioactive decay deep
down in the earth is used to heat water into steam. 44-45
9.27 Plenary Use the animation to discuss issues and efficiency
Risk Assessment Homework Vocabulary (key words)
Links with previous lessons
Builds on the ideas discuss last lesson when looking at generating electricity as mentions all that
changes is how you turn the turbine.
Energy from renewable sources can be used to drive turbines directly. Renewable sources used in this way
include wind, the rise & fall of water due to waves & tides, and the falling of water in hydroelectric schemes.
4Electricity can be produced directly from the sun’s radiation using solar cells.
In some volcanic areas hot water and steam rise to the surface. The steam can be tapped and used to drive
turbines. This is known as geothermal energy.
