Please answer ONE of the following questions in at least 5-8 sentences.
1. Oven Mitt:
How does an oven mitt successfully keep your hands from getting too hot when you reach into a hot oven?
2. Cookie:
You have a chocolate chip cookie that recently came out of the oven. You touch the outside of the cookie and it seems cool enough to eat. As you bite into it, a melted chocolate chip burns your tongue. How does this happen?
3. Plane:
In a recent movie about snakes and a plane, there was a need to turn the air circulation system on the plane off. In the movie, the inside of the plane became hotter once the air system was turned off. In real life, do you think the inside of the plane would get warmer or cooler without the air circulation system (do you think the air circulation system acts as a heater or air conditioner)?
