|Activity: Phase Change Simulations
|Time: 30 mins
- Material 1 – laptops and Explore Learning access
- Material 2 – journals
- Material 3 – pencils
- Material 4 – post-its
- Material 5 – long ropes or tape marked areas for human simulation
- Question 1 – Why does temperature cause phase changes?
- Plans for part 1 of activity:
- Students will explore the Gizmo: Phases of Water (http://www.explorelearning.com/index.cfm?method=cResource.dspView&ResourceID=661).
- Students will sketch the positioning of the molecules in each phase on post-it notes and stick them in their journals.
- Underneath each post-it, students will record the temperature and their observations of the behavior of the molecules in each phase.
- The students will be led to label the specific type of phase change between each post-it with directional arrows using the simulation for assistance.
- Students will share out their observations.
- Guiding Questions to ask during this part of the activity:
- How does the behavior of the molecules change?
- What does anything need to change its behavior?
- How is it related to the change in temperature?
- Anticipated Student Responses to guiding questions:
- They spread out, move greater distances as the temp. increases, in a pattern as a solid
- Various responses
- Plans for part 2 of activity:
- In their small groups, students will make a human model of the molecular behavior of phase changes.
- The teacher will call out solid, liquid and gas. To increase difficulty use freezing, melting, condensation, boiling.
- As an extension, challenge a group to model evaporation.
- small group work
- use of computer simulation and physical simulation
- Modification 1 – visual cues and labels on simulation
- Modification 2 – social interactions
- Modification 3 - being a physical piece in a simulation
|Check for Understanding The students will be assessed for understanding through their journal responses and the small group human model.
