1. Infer What is the energy source for the
water cycle?

the energy source is primarily the sun, and it drives the cycle by evaporating water from the oceans, lakes, rivers, and even the soil.

it also supports my hypothesis. if you rest first you can squeeze the clothespin more times. from the data i collected the average of the eight people concluded exercise makes your muscles more fatigued and less able to squeeze the clothespin compared to resting before squeezing.
