In these NGSS aligned activities/assessments, primary students analyze data to determine if a design solution works as intended to change the speed or direction of an object using a push or pull. In the first activity/assessment, a Ping-Pong ball is at rest and students observe and describe a how they can move the ball and identify the forces (a push or a pull or both) they used to make the ball move. Then they draw and describe themselves using a push or a pull to make the ball move.
The second activity/assessment, students predict and test the effects of small and large pushes and pulls on a toy car. Students measure, record, and make drawings showing the cause and effect of different kinds of pushes and pulls in terms of changing the speed and direction of toys.
K-PS2 Motion and Stability: Forces and Interactions
K-PS2-2. Analyze data to determine if a design solution works as intended to change the speed or direction of an object with a push or a pull.* [Clarification Statement: Examples of problems requiring a solution could include having a marble or other object move a certain distance, follow a particular path, and knock down other objects. Examples of solutions could include tools such as a ramp to increase the speed of the object and a structure that would cause an object such as a marble or ball to turn.] [Assessment Boundary: Assessment does not include friction as a mechanism for change in speed.]
Teaching tips, teacher background, photos for set up, student recording pages, rubrics for scoring, a tape measure to 50 and100, Core Math activity, Poem, Concept map, and large vocabulary words for a word wall are included.
