Solar Power Science

Monday, we had a beautiful sunny day which is exactly what we needed for our science day. I found a couple fun science activities from http://www.stevespanglerscience.com/ that I thought the kids would have a lot of fun with.
 The first was a solar bag. You fill it with air and then watch it rise as the sun heats the air inside the bag.

 We did one of the activities that came with it. The one we choose was to measure the height of the bag at one minute increments. The wind in CA made this a little difficult but we just recorded where it was even though the numbers went up and down.

 The second activity had the kids finding bits of nature and making a collage on solar paper.
 The designs left on the paper after it was exposed to direct sunlight turned out really cool.

 The last activity, I got mainly for the boys. We built a solar powered toy car. It was fragile but really a lot of fun. I only got one not knowing how well it would work but after seeing it go, I wish I had a few more. 9 kids sharing 1 car was interesting but they all got a turn.

We are currently working on Astronomy for science so these activities demonstrated just a few more amazing things our sun can do.
