I'm just a fan of Commander Chris Hadfield, astronaut.
Click on the links below to see his many short YouTube videos taken aboard the International Space Station (ISS) last year, the amazing photos he took from space to post on Twitter and Facebook, and the advice he gives to students when he travels around the world to give talks about his experiences aboard the ISS.

Cuban Tree Frog, Florida
Sometimes you have to take advantage of whatever heat source you have available...
Photograph by James Snyder
This pic was the Photo of the Day on the National Geographic Website for December 9, 2009.
Here' s the text that followed:
"This is a Cuban tree frog on a tree in my backyard in southern Florida. How and why he ate this light is a mystery. It should be noted that at the time I was taking this photo, I thought this frog was dead, having cooked himself from the inside. I'm happy to say I was wrong. After a few shots he adjusted his position. So after I was finished shooting him, I pulled the light out of his mouth and he was fine. Actually, I might be crazy but I don't think he was very happy when I took his light away."

Thermal Energy Transfer
How do research scientists living in the most severe weather on earth minimize heat loss from their bodies? Create a post in your Science Journal titled "Antarctica", and upload an image: identify and explain 3 examples of how humans can limit heat loss through:
1. conduction 2. convection 3. radiation
