Science Fair

Vivian and Allie did colors. They made playdough and learned what primary and secondary colors are.
Paige learned about the sense of taste and how you use your nose to taste your food. The soy sauce worked the best on the subjects and we all got a laugh out of it. The experiment was that you couldn't tell what the liquid was with your nose closed just that it was salty and then when you let go of your nose you got a strong taste of what it really was. The kids all made a really disgusting face. It was so cute.
Shannon's idea was to make a solar oven. She was not able to cook anything in it being as the weather here was not cooperating. The highest temp she was able to get was 103 not bad considering it was only 60 that day. p.s. she made the dress she's wearing too!!!
Madison did acids and bases. She made her own litmus paper out of red cabbage and tested various household chemicals and compared them against a control acid and base.


*****A fellow homeschooler set this up for our group in a retirement home where she works. Three of the residents watched our kids individual presentations and awarded them with certificates. We had a lot of kids participate that day and our kids really learned a lot. It was way cool.

Very cool! The solar oven may come in handy on the camping trip!

I did not know you could use cabbage as a litmus test!
