Energy Check at School

Here: measuring light intensity and temperature

What can we do to save energy at school?1. posters, signs 2. rules:

Turn off lights when not necessary Set the heating at 20 °C Close the windows before leaving Stop tabs from dripping

3. energy guards4. competition:

many prizes for many classes for the most possible

motivation

What can we do to save energy at home?

SLOGANS:

Sing a short song

Make 1,000 stepsBe Miss Watt

Let the sun shine

Top your roof
