Hypothesis:
My hypothesis is that yellow light will make the solar cells work
better. I think that because yellow is brighter. (Professor
Sunny’s note: Rachel used red, green, yellow and purple filters
with the photovoltaic cells)
Conclusion:
My conclusion is that yellow worked best out of four choices. But
purple doesn’t work so great.
