The "Academy of STEAM" series has been developed in order to cope with the new trend in education science that incorporates "Arts" within the STEM curriculum. The sets of this series are based on the new ENGINO's Multi-level Learning System. Each level corresponds to different skills that can be acquired through encompassing STEAM activities, starting from the practical (model building) going all the way to the abstract (learning through experiments). 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.
