Thermal Energy: Lesson 1.3 Activity 2 - Screen 2 Throughout the year, you can look up vocabulary words in the glossary to help you understand what they mean. © The Regents of the University of California.

Thermal Energy: Lesson 1.3 Activity 2 - Screen 2 In this unit, we will describe the smaller pieces that make up stuff by using the word molecule. © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 2 In the Sim, each circle represents one molecule. The Sim portrays molecules on a much larger scale than their size in real life. © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 2 The Sim shows a small number of molecules so we can easily observe what is happening to them. The things around us—even very small things—are made up of billions of molecules. © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 2 Key Concept 1. Things are made of molecules (or other types of atom groups). © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 3 What did you observe in the investigation? What could have caused the difference between how the food coloring moved in the two cups? © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 3 Now, you’ll use the Sim to model the food coloring investigation. This will help you find evidence to help explain why the food coloring spread out differently in the two water samples. © The Regents of the University of California. All rights reserved.

Activity 2 - Screen 3 Investigation Notebook pg 12 Thermal Energy: Lesson 1.3 Activity 2 - Screen 3 What evidence did you find in the Sim activity? © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 3 Use the evidence from the Sim to try to answer our question. Investigation Question: How is something different when it is warmer or cooler? © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 2 - Screen 3 Let’s revisit our question from the hands-on investigation with a more complete explanation of what’s happening to the water molecules. After using the Sim today, why do you think the food coloring spread faster in the hot water? © The Regents of the University of California. All rights reserved.

Investigation Notebook pg 13 Thermal Energy: Lesson 1.3 Activity 3 Let’s discuss the results of our poll. Which image shows the difference between the speed of molecules in hot and cold water? © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 Activity 3 Key Concept 2. When a thing gets hotter, its molecules are moving faster. © The Regents of the University of California. All rights reserved.

Thermal Energy: Lesson 1.3 Activity 4 For this activity, you will read and annotate an article about absolute zero to learn more about temperature and molecular speed. Then, you’ll answer some questions about it. © The Regents of the University of California. All rights reserved. Thermal Energy: Lesson 1.3 © The Regents of the University of California.
