Activity description

Now that you're working the Energy Sparks, run regular energy saving assemblies  to remind everyone in the school about the importance of saving energy and your progress towards your energy saving target. 

Here are some ideas of what you could share in your assemblies. Many of these suggestions link to another Energy Sparks activity, so you can score double points for your work:

  • You might want to show a short part of some of the videos here 
  • Review the Energy Sparks energy usage charts for your school. Present some of the Energy Sparks charts in an assembly. Explain to pupils what the charts show in terms of the main uses of energy at your school, and ask pupils for ideas of how you could save energy. Use the assembly to present an action plan to reduce energy use. Present a follow-up assembly after a  month to present Energy Sparks charts showing the change since the last assembly, and discuss further ways you could reduce energy use.

  • Present some of the data you have collected at your own school, through your monitoring campaigns, for example: 
    • Carry out a spot check to see if lights or electrical items are left on at lunch time 
    • Measure classroom temperatures 
    • Monitor whether outside doors and windows are closed during cold weather. 
    • Draw your own charts to present the data, and then present an assembly to tell your audience about what your results mean, and what the school could do next to reduce its energy use.

  • Use assemblies to introduce new energy policies to the rest of the school, for example: 
    • Introduce a policy on classroom temperature 
    • Introduce a policy on switching off lights, computers, and other information technology equipment. 
    • The assembly can be used to share why you are introducing the policy, who is responsible for the actions, how you will monitor how the school is doing and then to report back on whether the policy is making a difference.

  • Assemblies can also be used to launch energy saving campaigns at your school, for example: 
    • Run a campaign to switch off electrical equipment overnight 
    • Run a campaign to switch off lights and use natural light on sunny days.
