PROPERTIES OF MATTER LESSON 2B What Causes Matter to Change from a Solid to a Liquid or from a Liquid to a Solid?
Review: Changes in Matter Let s complete these sentences together for each kind of matter (ice, chocolate, and crayons) that we observed in our investigation: The matter I saw started as _________ and changed to _________. I think __________ caused the change in matter.
Review: Changes in Matter Do you think the changes in matter that we observed are reversible or not reversible? Explain why you think so.
Todays Focus Question What causes matter to change from a solid to a liquid or from a liquid to a solid?
What Causes Matter to Change? Using the words below, let s build two sentences that answer our focus question. Liquid Changes When heat is taken away Solid Becomes When heat is added One sentence will describe what causes matter to change from a solid to a liquid. The other sentence will describe what causes matter to change from a liquid to a solid.

Ways to Show How Matter Changes Some different ways to show how matter changes: Use data tables. Build sentences. Create graphics or diagrams with arrows and labels.
Show What You Know! Pairs: Use the picture and word cards to create sentences that answer our focus question: What causes matter to change from a solid to a liquid or from a liquid to a solid? Make sure your sentences include the science ideas we ve been learning about. If you need a word that isn t on any of the cards, write it on one of the blank cards.
Show What You Know! Let s communicate in scientific ways as we share our sentences! Listen to others ideas. Ask clarifying questions. Agree or disagree with others ideas. (Make sure to say why you agree or disagree!) Add your own ideas.
Next Time Graphic organizers like the one we used today can help us explain science ideas about changes in matter. How do you think scientists explain what happens when matter changes from a solid to a liquid or from a liquid to a solid?
