This week, Dora and I have been wrapping up our study of the sun. The timing couldn’t have been more perfect as we have been having a heat wave here. Today, we made a necklace for Dora using UV color changing beads from Steve Spangler Science and some elastic string. When kept inside, as long as you don’t get too close to any windows, the beads are white. The beads turn different colors, however, once they are exposed to sunlight. At high noon, the beads were quite dark, while at dusk, they were just a faint pastel color.
In addition, we did a small-scale model of the earth orbiting the sun. I put a big, yellow, circular magnet in the center of a pie pan. Then I added a marble that somewhat resembled the Earth on the outer edge of the pie pan. When we moved the pie pan back and forth, it gave Dora a better understanding of how the Earth orbits around the sun. Plus just getting the marble to revolve in the pie pan, without flying out, was a good motor skills challenge for her (okay, I’ll be honest, it was a challenge for me too!).
