Learning outcome: Our Sun provides so much energy to our planet that if we were to harness it efficiently all pollution and global warming problems would had been solved! Scientists invented the "photovoltaic" panels which can convert sunlight to electricity and can power up our machines with free and clean energy.
Experiment Method Description: Test how the area of a solar panel affects its overall efficiency. Observe the number of rotations in one minute when the solar panel is exposed under direct sunlight. Partially cover the panel’s surface and measure once again the number of rotations. Prove that the produced electricity increases when the collecting area of a panel gets larger.
Components: Solar blade, Engino parts, plastic skins and paper outlines, adhesive tape, piece of carton, sunlight.
Contains small parts which could be swallowed. Not suitable for children under 3 years old.
