In this lesson, students jump rope and write a description of what they observe about the forces on their bodies as they leave the ground and then return again. This lesson is a starting place to help students connect to their own lived experiences and does not require the use of the Playground Physics app.
2.1 — Jumping Rope – Part I
The playground physics app is not used in this lesson.
Expected Activity Time
- Total Activity Time: 45 minutes
- Introduction: 15 minutes
- Record a video: 15 minutes
- Discussion: 15 minutes
Materials and Prep
- Jump ropes (one jump rope per group of students)
- Worksheet: Force: Jumping Rope – Part I
Introduction: 15 minutes
- Tell students that as a class you are going to start investigating the question “How can I describe the forces on my body when I jump rope with a friend?” Write the question on the board and ask students to share their initial ideas to this question. Add their ideas to the board as they share them.
- Provide students with the worksheet Force: Jumping Rope Part 1. Have students write their own definitions for each of the five vocabulary words. Let students know that it is okay if they do not already know the definitions of the words. If they are not sure of the definition encourage them to take a guess or make up a silly definition based on what the word sounds like.
Investigation: 15 minutes
- Provide a jump rope to each group of students. Allow students time to jump rope while thinking about the forces acting on their bodies while jumping rope and how they would describe those forces.
- Once students have had time to play and jump rope, have them write a description of the forces acting on their bodies while jumping rope along with any questions that they have. Students should include the vocabulary words in their writing even if they don’t use them correctly. Encourage students to be creative in their writing. Learning about force with Playground Physics is intended to be fun!
Discussion: 15 minutes
- Allow students to share their ideas about the forces acting on their bodies while jumping rope and how they described it with the class.
- Write the words “Parking Lot” on a large piece of chart paper and post it at the front of the room. This is a place the students can post questions about their investigations and their wonderings in physics as the class moves through the lessons. Give each group of students a post-it note and have them write one of the questions they had about forces while jumping rope on the post-it. End the lesson by having each group share their question and place it in the “Parking Lot.” As students answer their questions that are in the “Parking Lot,” the questions can be removed. As the class moves through the lessons and new questions arise, they can be posted in the “Parking Lot. “
- Teachers may want to collect and hold on to students’ worksheets, as they will revisit the writing they did in this lesson at the end of the unit.
