Heat from the Sun

HEAT FROM THE SUN

Today we had some special visitors, they were Peter and Des. They are very interested in science. Des is a science teacher and Peter is an engineer.

They had a solar disc, that is like a sky dish, that has tin foil on it. Peter and Des demonstrated how to cook things on a solar disc. They even made paper burn by holding it in front of the disc. The paper smoked and then it burst into flames.

The disc used the sun to cook the pikelets. It was amazing.

Matt helped mix the pikelets and then the men put them into a pan. The pan was in front of the solar disc.

The pikelets were different because they had the secret ingredient, it was the solar energy! It was cool. We all got to try one.

Peter showed us a little plastic tug....but the really cool thing was, there was an electric motor on the boat and a solar panel on it’s roof and we put it in the swimming pool. The tug went around the green pool. When Peter put Samantha’s hat over the solar panel...it stopped!

We learnt lots of new words, like expand, parabolic and vaporize.

It was cool having 2 visitors in our class room and we learnt heaps of stuff about the solar energy.
