Objects move in different ways during physical activities on the playground.
Students communicate information about observations of the motion of objects on a playground and what causes the objects to move in order to determine initial criteria for the solution to the problem.
A school can’t reopen the playground until it receives a design for a new playground structure.

Lesson 1: Movement on the Playground begins with the scenario of a playground that needs to be redesigned. Students discuss why playgrounds are important, make observations of movement on the current playground, and use those observations to determine initial criteria to meet the design challenge of creating a new playground. They also determine initial investigation questions to gather evidence to support their design. Students explore forces and motion.
In Lesson 2: Forces Move Objects, students investigate the strength and direction of forces and resulting motion that happens in the process of a basketball game, specifically looking at what the movement was, how it happened, and how it can be applied to the problem.
Throughout the lesson, a flag () denotes formative assessment opportunities where you may change instruction in response to students’ level of understanding and making sense of phenomena.

Obtain and communicate information describing patterns of movement on the playground.
“Why do we have a playground? I think _____.Expected Student Response:
What can we do at recess that we can’t do in the classroom?”
Connect “why” students think recess is necessary to the question about what is their favorite activity in terms of movement.
“When on the playground, I like to _____ because _____.”Expected Student Response:
Keep this chart for reference in Step 16. Review the chart of the types of activities students like. If students listed basketball, soccer, and tug-of-war, circle them on the chart. If not, add them to the chart, stating that these are the activities they will be investigating during the next few days.
Use observations to describe movement on the playground, noting what causes the movement.
Depending on the situation, several groups could observe the same object.
Look at samples of 3.1.H1: Motion Observation to formatively assess prior knowledge of students’ ability to communicate their observations. Students may be sharing their observations using the kindergarten language of pushes, pulls rather than forces. If so, the term force is introduced in Step 11.
“How can you describe the motion of the objects that moved?”Expected Student Responses:
“What similarities or patterns did you see in the movement or nonmovement of all of the objects?”Expected Student Responses:
“What caused the objects to move?”Expected Student Response:
Students may be sharing their observations using the kindergarten language of pushes and pulls. If so, introduce the term force (any action that changes the shape or movement of an object). Explain that from now on they will be using this term to describe movement.
Identify initial criteria for a problem’s solution based on observations of movement and its causes.
Lesson 2: Forces Move Objects, Lesson 3: Patterns of Motion, and Lesson 4: Balanced and Unbalanced Forces are built on answers to these 3 questions, and rubrics are found in Lesson 2: Forces Move Objects and Lesson 3: Patterns of Motion to formatively measure student understanding about force and motion.
Students should suggest the following for criteria: motion, motion changes direction and strength, pattern of predictability, and forces. The idea of balance and unbalanced forces will most likely not be mentioned in the list yet. They will learn more about this in Lesson 2: Forces Move Objects. It can be added to the criteria list then.
Save each chart and add new learnings and wonderings to it after each lesson activity.
