This year Tucker and Hunter both wanted to participate in the science fair at school. Thankfully, they decided this enough in advance that I could help each of them on different weekends to do their experiments and then still have a weekend to work on their posters.
After taking a simple quiz from one of the websites we settled on making plastic from milk, a simple project that could be completed in one day :)
first you have to warm up the milk then add it to the vinegar to curdle the milk
Then you separate it
and squeeze out the extra liquid
He won a ribbon for first place (there were only a couple of other 1st graders participating)
Hunter wanted to make something different but thankfully let me have him do dry ice experiments instead.
Hunter loved that gas came out of the bubbles when he popped them.
He originally called the gas steam but couldn't explain why it wasn't hot and thought that cold water would not let it 'steam.' He was surprised that there was still gas when using cold water.
Hunter thought it was cool that one of the judges' first experiments when he was younger was also with dry ice.
And here are a couple of pictures
