A pinwheel is a childrens’ toy used for simply entertainment. It works by children blowing into the pinwheel hence making it spin. However, when a solar panel is attached to the pinwheel it uses the solar energy and is able to spin automatically.
A solar cell is a cell which converts energy from the sun (solar energy) into electrical energy. Many solar cells make up a solar panel which can be used for many purposes such as making a pinwheel spin. A solar panel can cost anywhere from $10- $1000. The solar panel we purchased costed $16.95
Solar cells are made of semi
conductors.
A solar cell is made up of two layers of semi-conductor.
Each layer is made up of silicon and small amounts of phosphorous and boron are added to each layer.

Most of our materials were obtained from home such as: cardboard, pencils, straws. The motor and solar panel were bought from the shop Jaycar. The problems we encountered were: trying to stick the pinwheel to the ground and getting the pinwheel to spin.
1.We used cardboard and folded it in the shape of a pinwheel
2.We attached the cardboard to a wooden stick using a nail.
3.We attached the motor to the nail and connected the motor to a solar panel using wires which travelled down the wooden stick.
4.We put the solar panel under sunlight and the pinwheel began to spin.
