Station 1 – The Greenhouse Effect
What is the atmosphere?
Our atmosphere is a thin layer of air surrounding the earth.
Pretend the model’s plastic bubble is the atmosphere.
T
1. Using the greenhouse model, while in the sun or under the lamp, measure
the temperature inside and outside simultaneously over a three minute
period. Record your readings in the table below.
Time (minutes)
T1 (oC)
(outside temperature)
T2 (oC)
(inside temperature)

Name three Greenhouse Gases. ________________________________
____________________________, _____________________________.
Would you like to live in a world that was as hot as it became under the
bubble all the time? __________________
The air is a mix of different kinds of gases. If too much of that mix is made
up of greenhouse gases, the air temperature starts to increase. When we
burn less coal, petrol, oil and other fossil fuels we release less
greenhouse gases into the atmosphere.

Station 2 – Sustainable Technologies - Wind Power
Wind turbines come in many different sizes. The bigger the wind turbine blades, the
greater the power output from the wind turbine.
The higher the wind speed the greater the power generated.

Station 3 – Sustainable Transport
How do we use energy to move ourselves and our
things around?
What are some examples of fossil fuels?
(ask your volunteer if you’re unsure)
What are some ways we can choose to move ourselves around which use
less fossil fuels (or even none at all)? (Lift the red lids for clues)
Circle ONLY the sustainable forms of transport below

Station 4 – Greenhouse Bike
“Saving energy”
1.
Pedal the bicycle.
Pedalling the bike you are using mechanical (kinetic) energy. This
energy is changed to _______________ energy to power the
appliances.
List the electrical items have you
powered
Power required (Watts)
[ Read from the display]
The electricity most people use is produced by coal burning power stations. Burning
coal produces carbon dioxide.
2.
What atmospheric gas is represented by the bubbles in the
greenhouse gasometer? __________________________.
2.
Place the following words in the paragraph below.
increased, carbon dioxide, burning coal, warmth, fossil fuels
The greenhouse effect is a natural process in the atmosphere.
Greenhouse gases trap the sun’s ______________.
Human activities such as
___________________________ have
led to ______________ concentrations of greenhouse gases such as
___________________________ in the atmosphere.
We can minimise the greenhouse effect by burning less

Station 5a – Reducing our Impact on the Environment
How can we save energy and water at SCHOOL & HOME?
1. Using ideas you have seen in the Eco-House or by looking at the
pictures below, list ways you can save energy and water at home.
In the
kitchen/canteen
In the bathroom
Yard/ garden
Other places
eg. classroom

Station 5b – Reducing our Impact on the Environment
The four ‘“Rs”
Reducing waste is a good way of becoming sustainable.
To help us, we can remember the four ”R”s
Reduce
- Don’t buy things we don’t really need
Refuse
- Don’t buy packaged items
Reuse
- Take green shopping bags to the shops
Recycle
- Use old things to make new ones
Activity
Each person in your group is given a piece of garbage. You have to place the item in
the proper garbage bin.
TICK THE CORRECT BOX
Yellow bin – used for
 General rubbish
 Recyclables
 Green waste
Green bin – used for
 Glass
 General rubbish
 Green waste
Red bin – used for
 Plastic
 General rubbish
 Green waste

Station 6 - Solar Investigation - Solar Powered Pump
Making electricity from the sun is called Solar Power. Solar energy does not pollute the
air and can be used instead of the energy from a power point. Solar Pumps can be used
in areas with no conventional electricity for pumping water to crops or for drinking water.
The solar photovoltaic panel converts sunlight into electricity. We can use solar electricity
to power a water pump.
Working in your group, complete the following investigation.
Objective: When does the solar pump work best?
Procedure: Record how long it takes to fill the bucket with water from the
solar pump in the following conditions A and B.
A
B
Results:
Pump operating conditions
Time (seconds)
A The solar panel pointing directly towards the sun.
B The solar panel held parallel to the sun’s rays.
C The solar panel with half the cells covered.
Conclusion: The pump works best when
