Have a discussion and make predictions about what you think will happen to the water in each glass.
Experiments on solar panels.
Or analyze how solar cells or panels work.
If you re interested in creating your own science fair project see science fair projects for dummies cheat sheet for some tips and information to get you started.
Place the cubes outside in your backyard on a sunny but not too hot day.
The experiments test how radiation and rocket launches could affect dye sensitized solar cells which the students say are safer and easier to make than traditional solar panels.
Cover one of the glasses on white paper with plastic.
Measure the water temperature and set one cup on each paper.
Have your child make a guess on which cube will melt faster.
A future experiment would use mirrors in front of the solar panel rather than bi convex lenses which would increase the amount of sunlight coming into contact with the photovoltaic cells.
Place one cube directly in the sun and the other in full shade.
Experiment with solar power by building your own solar powered robot or oven or by testing ways to speed up an existing solar car.
