In this lesson, students revisit the writing they did at the beginning of the unit to add in more details and demonstrate all that they have learned about forces.
2.7 — Force: Double Dutch
Note that the Playground Physics app is not required for this lesson.
Expected Activity Time
- Total Activity Time: 45 minutes
- Introduction: 10 minutes
- Investigation: 20 minutes
- Discussion: 15 minutes
Materials and Prep
- Force: Odd One Out Worksheet
- iPad with Playground Physics app (optional)
Introduction (10 minutes)
- Remind students that as a class you have been investigating the question “How can I describe the forces on my body when I jump rope with a friend?”
- Pass back to students the worksheets that you collected from them during the first lesson, Force: Jumping Rope Part I.
- Have students read what they wrote for the definitions of the vocabulary words and the explanation of jumping rope on their worksheet at the beginning of the lesson.
Investigation (20 minutes)
- Pass out the worksheet Force: Double Dutch.
- Allow students time to reflect on what they have learned and to complete the worksheet.
Discussion (15 minutes)
- Allow students to share how their ideas about the forces involved with jumping rope have changed since they first wrote their narratives.
- Encourage students to share their reflections about the process of practicing science. What do they feel they have learned about doing science from this investigation and through the use of the Playground Physics app?
- As a class, revisit the “Parking Lot” of questions. Any questions remaining in the parking lot that have been answered can be removed. Any new questions that students have now that they know more can be added to the “Parking Lot”. Provide post-in notes and allow students to add any questions they have.
- If students want to explore their remaining questions or new questions in more detail, Lesson 0.4 Science Investigation can be used to help structure these investigations.
