Tests at Pine Ridge Weather Station

11. A weather team at Pine Ridge Station wanted to learn how mountain cold and warmth change materials. The team used a warming box and a cold outdoor shelf. They recorded what happened before and after each test.

22. First, the team put a snowball in the warming box. After a while, it became liquid water. They put a cup of liquid water on the cold shelf. Later, the water became ice. The team also warmed a piece of chocolate until it melted. When the melted chocolate cooled, it became solid again.

33. An adult placed a raw egg in hot water. The egg white became firm. After the egg cooled, it stayed firm. The team also warmed a slice of bread. The bread became brown and crisp.
