Kindergarten: Forces and Interactions
Next Generation Science Standards addressed in this packet:
K-PS2-1: Plan and conduct an investigation to compare the effects of different strengths or different directions of pushes and pulls on the motion of an object.
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.
Activity 1 materials: toy cars, meter sticks (or printed meter sticks from the internet or just tape on the floor marking distance for about 5 meters). Using the cars students will investigate the effect of push strength on distance traveled. Students will take turns pushing their car on the floor and recording the distance. Worksheets provided. I do this as a whole class activity, I have 16 kindergarteners, everyone gets to go twice.We then discuss what makes the car stop (friction), worksheet provided.
Activity 2: materials: same as Activity 1 and you will also need a ramp (poster board on a stack of books works!) Using the cars, students will investigate the effect of ramps on distance. Worksheets provided. I do this with my 16 kindergarteners working in groups of 4. I set up 4 ramps in 4 different areas of my classroom.
Activity 3: materials: same as Activity 2, and paper towel or toilet paper rolls, cars or ping pong balls. Using the cars or ping pong balls, challenge your students to create a track that has a direction change in it! Your kids will get so creative with this – I love to see what my kids come up with! Photos of my students’ creations included. I do this with my 16 kindergarteners working in groups of 4. I set up 4 ramps in 4 different areas of my classroom. Have your students try to change the speed of the ball by changing the angle of the ramp- worksheet included.
