Essential Understanding

The student knows that objects have properties and patterns.

Science Background

Heat and Temperature: Annenberg Learner (website) - Heat is the transfer of energy between two objects with different temperatures. Build your understanding of heat and temperature through easy-to-follow text and video (58 minutes).

Signature Lesson

Water and Ice: Science NetLinks (website) - Water changes from a solid to liquid and back again, in this inquiry lesson.

Supporting Lessons

Melting and Freezing: Science NetLinks (website) - Investigate what happens to the amount of different substances as they change from a solid to a liquid or a liquid to solid.

Elaboration Lessons and Extensions

Change It: FOSS (website) - How can you change a liquid into a solid, or a solid into a liquid? Students place different objects in the oven and freezer to see what happens.

Assessment Ideas

The following investigation can help you assess your students’ understanding of how heat can change the physical properties of some materials.

Remove one frozen popsicle (flavored ice) from the freezer. Have students observe this popsicle in its plastic tube and compare it with a second popsicle, which has been left at room temperature and is in liquid form. Student pairs should discuss the similarities and differences between the two popsicles. Then, have students take both popsicles outside, into the sunshine, and predict what will happen to them. Students should observe and discuss what happens to the popsicles after 5 minutes, and again after 10 minutes. Ask the following questions.

  • What happened to the frozen popsicle in the hot sunshine?
  • What happened to the room temperature (liquid) popsicle in the hot sunshine?
  • Why did the changes occur?
