During Spring Break, I went to Mexico Beach, Florida. I was walking barefoot on the soft, cool grass, but when I got to the sand, I noticed that my feet were burning! Ouch! This is an example of _________________.

• conduction

• convection

• radiation

During Spring Break, at Mexico Beach, I also got a terrible sunburn! Ouch! This is an example of ________________.

• conduction

• convection

• radiation

Mrs. Tully's class was investigating the heat flow with warmer objects and colder objects. Sawyer and Brody decided to observe what happened when ice cubes were placed in the palm of their hands. After a few minutes of holding the ice cubes in their hands, the ice cubes began to melt. Then the boys began to complain that their palms were freezing. Mrs. Tully told Sawyer and Brody to put their ice cubes away and write a conclusion based on their observations. Using what you know about heat transfer, choose the BEST conclusion statement for their investigation.

• The heat from the palms of their hands transferred to the ice cubes.

• The ice cubes evaporated, changing from a liquid to a gas.

• There was no change in the ice cubes - they remained solids.

• The cold from the ice cubes turned the palms of their hands red.
