Can help with these questions. Thanks
although more accurately, it should be light (Sun) --> electrical (circuit) --> light + heat (bulb)
solar energy is not one of the forms of energy that they learn, they learn light and heat
For the second one, I think the best answer is (1)
light does not affect rate of evaporation, gravity is acting on both towels, and the exposed surface area of both towels are the same. Towel A has less water as the water dripped down from the towel, while for Towel B, the water remained on the towel due to its placement on the plate.

i can’t comment on the CL part though, but based on the discussion in the chat group, seems like they do a lot.
