Dr. Dower Visit

Dr. Dower came today to talk to us about his job as a scientist. He showed us some of the different protection he wears at the lab.

He showed us an invention that he made and how long he worked on solving that problem. My kiddos faces were shocked when he told them how long it took to create this invention. They have a hard time working on the same thing for a week, so years seems crazy!
The invention is a protection for the radio connection for cell phone towers.

We reviewed matter: solid, liquid, gas.
Then we did experiments with liquid nitrogen.
