After a highly successful kindergarten registration, we turned our attention to Issa's Science Fair. She has literally been working on her project for months. One thing I will say for her is she doesn't take the easy way out! When we started talking about project ideas, she decided she wanted to invent raiser shoes. The spelling is very important there. She wanted to design shoes that had built in stools. It's actually a pretty cool idea.
Daddy was all over this, and he wanted to be sure she started with the mechanics of raising things. So...she and I did some library research on simple machines, and she decided gears, pulleys, and levers were all viable options. From that point, she and Daddy started sketching. He even taught her how to use some simple computer drafting software and how to share her desktop via Skype so they would work on it when he was out of town. It's pretty amazing to watch your seven year old share a desktop.
She ultimately decided on scissor jacks, which she taught me are first-class levers, as the design of choice:
She then had to sand the toothpicks to make them fit:
We had a blast at the science fair. As always, making ice cream was the favorite event:
