Experiments are a perfect way to expand your mind to the concepts of STEM and the physical world.
While we may be stuck indoors, there are still ways you can harness the power of light to learn about the concepts of natural phenomena like solar energy!
Here are three experiments you can do yourself at home with the same set of materials for the whole family to enjoy, derived from CME’s very own solar4STEM science kits!
Materials for Experiments
These materials can be reused for all these experiments:
1 – Varying Light Intensities on a Solar Panel
Solar energy works by capturing photons and turning them into electricity; what do you predict will happen when the intensity of light, or the amount of photons, changes? Is there a limit to the efficiency of a solar panel?
2 – Optimum Orientation of a Solar Panel
Solar panels work through the photoelectric effect, where photons collide and dislodge electrons located in the solar cell. What were to happen if we adjusted the orientation of the solar panel? Is there an ideal angle which allows photons to collide with the solar panel to eject the most electrons?
3 – Temperature Affecting Energy Collection
Photons kick electrons out of their existing energy states to produce a current; this difference from initial to final energies gives us electricity. Temperature is the measure of average kinetic energy; if we were to raise the temperature, what would happen to the electron’s initial energy? If the energy provided by the photon were to not change, what would happen to the overall energy collection? Follow these steps to find out:
With these three experiments, you can bring the world of solar energy right into your home!
