INTRODUCTION TO SUN POWER
The energy we use today is usually obtained from fossil fuels, such as oil, gas or coal.
Even electricity is a fossil fuel, because most of the electricity generated today is made
by burning one of these three kinds of raw material.
Fossil fuels like coal, gas and oil, which we use for things like heating, lighting, and
cooking, won’t last forever. One day the world’s supply will run out. So what will take
their place? One possibility is energy from the sun. which we call solar energy. For
many years now scientists have been developing ways of collecting and using solar
energy, because it is clean, sate and something the world cannot run out of – though
obviously some parts of the world have more of it than others!
The experiments in this kit should give you some idea about how the sun’s rays create
energy. As this kit deals with solar energy, there are some experiments that may not
give you good results without strong sunlight. These experiments are marked with this
sign:
You will find a few experiments that require adult supervision. These experiments are
marked with this sign:
After reading this short introduction, you are ready to start with your experiments.
