Middle School Physical Science Teacher Guide

(PS-3852)

Features 23 core lab activities that cover the fundamental concepts of Force & Motion, Energy Transfer, Electricity & Circuits, Fluids and more.

Speed and Velocity

Lab Summary

Use a motion sensor to measure the position and velocity of a moving object.

Theory

In this activity, students learn about the related concepts of speed and velocity and how to graph speed and velocity versus time. They also:

  • Observe that speed is the rate at which position changes and that average speed is the distance an object travels divided by the time it was traveling
  • Observe that a complete description of velocity includes speed, direction, and a frame of reference
  • Measure and describe their own velocity (speed and direction)

Method

Students gain experience conducting the following procedures:

  • Setting up the equipment and work area to measure the position and velocity of a moving object
  • Measuring distance and time data and plotting it on a graph
  • Recording their own motion as they follow instructions that include distance, speed,
    direction, and time
  • Using math skills to compute rate of speed, given distance, and time

Sensors / Equipment Used:

PASPORT Motion Sensor

(PS-2103A)

The PASPORT Motion Sensor accurately measures position, velocity, and acceleration of a target. Can be used to track the motion of carts, balls, people and more.
