Luke loves freezing things. He is constantly freezing lego guys, cars, pennies and anything else small he finds. Luke experiments with the temperatures to freeze things at, he experiments with how much the water grows when it turns into ice, and he has even experimented with freezing different types of liquids including adding lots of salt to the water. Mainly, he just loves freezing things, but he is learning a lot in the process.
For older kids or super science nuts:
Did you know that scientists have recently made discoveries changing why they believe ice is slippery? It might seem like a simple question and answer, but apparently it's not. Here is a link from the NY Times showing old and new theories of why ice is slippery.
In our family, we especially love ice because we love to skate on it. Luke and Megan have been taking ice skating lessons and are doing great! I just found a website that talks about the science of hockey. I think Luke will really enjoy reading it.
