Making Objects Move Faster or SlowerActivities & Teaching Strategies
Active learning helps students connect abstract force concepts to their own experiences. When children push toy cars and balls, they directly feel how force changes motion, building lasting understanding. Hands-on exploration makes Newton’s ideas concrete, especially for young learners who learn best by doing and seeing.
Learning Objectives
- 1Compare the effect of varying forces on the speed of a rolling object.
- 2Explain the actions required to change the direction of a moving object.
- 3Predict the outcome of applying a greater force to an object compared to a lesser force.
- 4Identify factors that can slow down or stop a moving object.

Ramp Push Challenge
Build ramps from books and cardboard. Students predict, then push toy cars with light, medium, and hard forces, timing speed over a marked distance. Record results on group charts and compare predictions to observations.
Prepare & details
Predict how applying more force affects an object's speed.
Facilitation Tip: During Ramp Push Challenge, ask students to whisper-predict how far the car will travel before each push to encourage reasoning before action.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Ball Stop Station
Roll balls across surfaces like carpet, tile, and grass. Students apply varying stopping pushes and note distances traveled. Discuss why some surfaces need more force to stop motion.
Prepare & details
Explain how to make a rolling ball stop.
Facilitation Tip: During Ball Stop Station, have students trace the ball’s path with their fingers before stopping it to build directional awareness.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
String Pull Races
Tie strings to small toys and pull across tables with different strengths. Pairs race toys, measure finish times, and switch roles to feel force differences. Chart which pulls made toys fastest.
Prepare & details
Compare the effort needed to push a small toy car versus a large box.
Facilitation Tip: During String Pull Races, time each student’s pull with a stopwatch so they see the direct link between effort and speed.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Whole Class Prediction Wall
Display objects like balls and cars. Class predicts and votes on speed changes from more force, then tests one by one with student volunteers. Update wall with evidence.
Prepare & details
Predict how applying more force affects an object's speed.
Facilitation Tip: During Whole Class Prediction Wall, use colored sticky notes so students can visually group similar predictions before testing.
Setup: Varies; may include outdoor space, lab, or community setting
Materials: Experience setup materials, Reflection journal with prompts, Observation worksheet, Connection-to-content framework
Teaching This Topic
Start with simple materials to reduce cognitive load while maximizing exploration. Model how to change one variable at a time, like force strength, so students isolate cause and effect. Avoid over-explaining—let students discover patterns through repeated trials. Research shows that guided inquiry, where students test ideas and adjust predictions, leads to deeper understanding than direct instruction for force concepts.
What to Expect
Successful learning looks like students using force vocabulary accurately, predicting speed changes before testing, and explaining why motion changes through evidence. They should connect their trials to real-life pushes and pulls, like swinging or stopping rolling objects. Discussions should show clear reasoning tied to force observations.
These activities are a starting point. A full mission is the experience.

Watch Out for These Misconceptions
Common MisconceptionDuring Ramp Push Challenge, watch for students who assume the heavier car will always move slower, even with the same push.
What to Teach Instead
Ask students to push the light and heavy cars with equal force and time both trials. Have them present their times side-by-side so the group sees that size alone doesn’t determine speed when force is controlled.
Common MisconceptionDuring Ball Stop Station, listen for ideas that balls stop 'because they get tired' instead of forces like friction or obstacles.
What to Teach Instead
Have students roll the ball on different floors and observe which surfaces make the ball stop faster. Ask them to name the invisible force slowing the ball and share findings with the class.
Common MisconceptionDuring String Pull Races, notice students who think a ball changes direction without a sideways force.
What to Teach Instead
Ask students to pull the string straight and sideways separately, then describe how each force changes the ball’s path. Have them act out the forces with their bodies to reinforce the connection.
Assessment Ideas
After Ramp Push Challenge, give each student a toy car and small ramp. Ask them to draw the car pushed with light force and strong force, then write one sentence comparing the speeds. Collect tickets to check for accurate vocabulary and observations.
After Ball Stop Station, present the scenario: 'A ball rolls toward a wall. What are three ways to stop or change its direction?' Facilitate a discussion where students use 'force,' 'push,' or 'pull' in their answers, noting who applies the vocabulary correctly.
During String Pull Races, place a large box and small car at the front. Ask students to raise hands for little, medium, or lots of effort needed to push each object. Then, have volunteers try pushing and report back to show if their predictions matched actual effort.
Extensions & Scaffolding
- Challenge: Ask students to design a ramp that makes a car move fastest using only one cardboard sheet and tape.
- Scaffolding: Provide picture cards of pushes and pulls for students to match to the correct force word during stations.
- Deeper: Introduce the term 'friction' after Ball Stop Station and have students test balls on different surfaces like carpet, tile, and sandpaper.
Key Vocabulary
| Force | A push or a pull that can make an object move, stop moving, or change direction. |
| Speed | How fast an object is moving. It is measured by how far an object travels in a certain amount of time. |
| Direction | The path along which something moves or is aimed. |
| Friction | A force that opposes motion when two surfaces rub against each other, often causing things to slow down. |
