Activity 1.1: Building an action model
of the carbon cycle
Group A Carbon stores (4 pupils): need a bag of 8
carbon beads and an instruction card.
Group B Natural processes (7 pupils): need instruction
cards to show how carbon is moved around in the
carbon cycle.
Group C Sunshine (1-4 pupils): do not need cards or
beads. This group makes sure the carbon moves around
as it should to make the model work.

Activity 3.1
What’s your carbon footprint?
Carry out the tasks in the ‘Footprint calculator’
spreadsheet.
To discuss:
How does your ranking of activities compare with other
people’s?
What would be the easiest and the most difficult
activities to change to reduce the carbon footprint?
What are the main difficulties in working out an
individual’s carbon footprint?
What additional information would you need to calculate
an individual’s carbon footprint for a year?

Activity 4.1:
Installing a wind farm
Learning outcomes
You will be able to:
• Use a project management tool.
• Assemble a 3D exhibition to communicate closed
loop ideas to a specific audience.
• Produce and work to a plan for a group project.
• Justify a wind farm referring to closed loop
theory.

Activity 4.1:
Installing a wind farm: the challenge
You need to convince your community of the value of
installing a wind farm.
Overview of the challenge
a. Identify a suitable community for wind-powered
energy in your region (roughly 5000 people).
b. Work out how many wind turbines you would need to
supply them with energy.
c. Identify the site(s) where the turbines might be
located.
d. Plan an exhibition for the town hall to gain public
support for your proposal.

a. Construct an exhibit proposing a wind farm site in
your area. Design the exhibit to be displayed in a 3D
cabinet measuring 60 cm x 60 cm x 30 cm.
b. The exhibit must display accurate STEM information
and data (research into turbines is needed).
c. The exhibit must include a map showing where the
turbines would be located in your borough. Justify
your choice of sites for the turbines.
d. The exhibit must aim to convince local people of short
and long term benefits, by referring to closed loop
ideas.

1. Your project will be judged on how effectively you
organise your work. The following criteria will be used
to judge your group’s work:
2. Did you produce a clear project plan?
3. Was everyone in the team given an appropriate role?
4. Did the planning of tasks allow the group to carry out
the exhibit brief provided?
5. Did everyone finish their tasks on time?
6. Did other members of the group help when people
fell behind?
