Shadow Chalk Experiment

Shadow Chalk Experiment (5)

Travis has made sundials before, but never before has he used his whole body for the activity! This might be the coolest version we’ve tried yet.

Okay, so it wasn’t as precise as past versions, since the measurement (your body!) is big and you have to remember to pop outside. But at 9 a.m., 1 p.m., and 4 p.m. intervals, Travis stood with his feet in the same spot on our patio. He held a big stick for extra effect and struck a dramatic pose.

Each time, I traced his outline and marked the time.

Sure enough, it was long and aimed to the south in the morning, short and stubby at 1 p.m, and long and to the north by late afternoon.

If your kids want to, have them color in their shape each time with fun patterns or colors! Travis preferred to leave his blank, but we still had a neat record of the sun’s passing by the end of the day.
