Experiments on the effectsThe melting of the ice worldwide
North Pole South PoleResults:Melted ice from continents and the thermic expansion of the oceans will cause a rise of the sea level. severe flooding of low-lying areas
Why should we tackle the problem?

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
