Solar Energy is everywhere
The sun gives off more energy in one second, than people have used from the beginning of time .It is bigger than anything we can really imagine -- a million planet earths would fit inside it! It takes millions of years for the energy from the center of the sun to reach the sunâ€™s surface. And then just eight minutes for it to travel the 93 million miles to earth.

We harvested lots of solar energy in September and October. On two days the temperature of the water increased by 8 ºC. The lowest increase of temperature was 2º C on the 28th of September. The average increase in temperature was 5.5º C We were very successful harvesting solar energy in September and October.

Using Solar Energy to Purify Water We put 600ml of salty water into a plastic container. We used food colouring to turn the water red.
Then we put a small bowl standing in the middle of the plastic container
We used cling wrap to cover the container. We used an eraser to weigh down the centre of the cling wrap. We put in the window facing the sun. After a while we noticed drops of moisture on the cling wrap. The moisture dropped into the small bowl. We collected a small amount of clean water. By Laura Kelly
We built this eco-house in class it took one day to build. It has a fan on one side of the roof and an alarm on the other side. It has a ladder on the right side of the house and a fence surrounding the house. You can use it in solar mode but due to limited power supply only one electric consuming part such as the windmill and alarm . The solar panel cannot hold solar energy inside it. So we have to use batteries as a back up
Our teacher brought in a lamp that works on solar energy. We put the lamp in the window and used the energy from the sun to recharge the battery. The next day we put the lamp on our table to see how long the energy would last.
