Causing Motion

Causing Motion

Enduring Understanding

  • A variety of forces are always acting upon objects, affecting their movement.

Essential Questions

  1. What is the relationship between motion and energy?

  2. How do forces influence motion?

  3. How can we model forces and motion?

  4. How does an object’s mass influence motion?

Observations and Discussions

Movement Description

  • Discuss the type of movement observed in the tube.

  • Consider how the tube is moving.

Delivery System

  • Explore the use of compressed air to push or pull a tube-shaped container.

  • Identify what is causing the movement of the containers for delivery.

Object Selection

  • Discuss which objects to move for the project-based learning (PBL) activity.

  • Share ideas with table groups.

Moving Objects

  • Identify objects and materials needed to achieve project goals.

  • Discuss methods for moving these objects.

Device Features

  • Consider necessary features for the device to effectively move objects.

  • Understand the importance of starting, stopping, and changing movement in planning.

Lesson Activities

Toy Car Exploration

  • Use a toy car as a model to explore causes of motion.

  • Complete Fan-N-Pick Cards in any order, recording observations in journals.

Movement Scenarios

  • Experiment with different methods to start the car's movement:

    • Use 1 or 2 rubber bands.

    • Use fingers, hands, or feet.

    • Start movement from various positions (back, front, side).

    • Move the car up and down a ramp.

Observations and Reflections

Observational Questions

  • Describe the car's state before and after movement.

  • Discuss the duration of the effect on the toy car.

  • Analyze how to move, stop, or change direction of the car.

Vocabulary for Responses

  • Use terms: up, down, forward, backward, push, pull.

Forces and Motion

Discussion on Forces

  • Discuss the forces used to make the car move, stop, or change direction.

  • Define force as a push or pull and motion as the change in position.

Energy Transfer

  • Explain that energy must be transferred to change an object's state from rest to motion.

  • Discuss how a push or pull (force) transfers energy, resulting in motion.

Energy Concepts

Kinetic vs. Potential Energy

  • Kinetic Energy: Energy of motion; examples include meteors, walking, falling, throwing a ball, flying airplanes.

  • Potential Energy: Stored energy that can be converted into kinetic energy.

Kinetic Energy in Action

  • Reflect on when the toy car had kinetic energy during experiments.

  • Discuss energy transfer methods for different scenarios.

Illustrating Forces

Force Diagrams

  • Discuss how to illustrate a force acting on an object using diagrams.

  • Use arrows to represent motion and direction of forces.

Key Vocabulary

  • Collision: Interaction between objects.

  • Direction: The path along which something moves.

  • Friction: Resistance that one surface or object encounters when moving over another.

  • Mass: The amount of matter in an object.

  • Rest: The state of an object being stationary.

  • Energy: The capacity to do work.

  • Hypothesis: A proposed explanation for a phenomenon.

  • Motion: The action of moving or being moved.

  • Speed: The rate at which an object covers distance.

  • Conclusion: A summary of findings.

  • Energy Transfer: The process of energy moving from one object to another.

  • Independent Variable: The variable that is changed in an experiment.

  • Dependent Variable: The variable that is measured in an experiment.

  • Force: A push or pull on an object.

  • Kinetic Energy: Energy of an object in motion.

  • Position: The location of an object.

  • Work: The energy transferred when a force is applied to an object.
