How does this experiment compare to the changes the students have already seen in class?

Ms. Sloan's students are studying changes and heat energy in science. They have recently made models of the water cycle and learned how the sun can turn liquid water into steam. They also took some ice cubes from the freezer and let them melt on the lab table. Next Ms. Sloan gave each group some sugar cubes. She asked each group to grind up the cubes. "What kind of change is this?" she asked. "A physical change!" the class responded. Next Ms. Sloan got out the hot plate and put some sugar cubes in a pan. She began heating the sugar cubes.

• Heating the sugar did not affect the solid sugar cubes.

• Heating the solid sugar cubes caused evaporation and the sugar disappeared.

• Heating the sugar caused something new to form and a chemical change to occur.

• Heating the solid sugar cubes caused melting and a physical change to occur.

Diana had a frozen ice cube and frozen Popsicle. She let both of them melt and refroze them shortly after they melted. They underwent a change.

What happened to these frozen goods?

• There was no change.

• They went through a physical change.

• They went through a chemical change.

• The ice cube became a Popsicle and the Popsicle became an ice cube.

Think about how water would change if an ice cube tray with ice was left on the counter over night and then placed back in the freezer the next day. In what order would the phases of water be from the ice pulled out of the freezer the first time to pulling it out after it was frozen the second time?
