Students will trace the changes in the position of an object over time such as a cup rolling on the floor and a car rolling down a ramp.
The student knows that forces cause change and energy exists in many forms.
Galileo Drops the Ball: Schlumberger Excellence in Educational Development (website) - What would drop faster, a feather or a cannonball? How about a large cannonball versus a small one? Use this fun, interactive website to simulate the test. You even can switch from Normal to Vacuum Mode, to run the test where there is no air.
Work, Energy, and Power: The Physics Classroom (website) - This online tutorial, focusing on the relationship between energy and motion, was written for high school physics students, but is a great resource for teachers.
The Force Be with You! Prince Edward Island (CA) Department of Education and Early Childhood Development (website) - Introduction to the concept of force, different types of force, the effects of different forces on Earth, and related topics. Content is appropriate for teachers and/or students.
Force Affects Motion: School for Champions (website) - Helpful explanation of how force affects motion, including references to “push,” “pull,” “gravity,” “friction,” and “magnetism.”
Making Objects Move: Science NetLinks (website) - Students identify ways to make objects move and then build a structure that can be used to move an object from one place to another.
- Supporting Lessons
- Assessment Ideas
- Literature Connections
- Additional Resources
Ramps 1, Let it Roll: Science NetLinks (website) - Students explore and measure the rate at which spherical objects roll down a ramp.
Ramps 2, Ramp Builder: Science NetLinks (website) - Students to plan, build and test ramps that allow rolling objects to travel long distances.
Elaboration Lessons and Extensions
Falling for Gravity: Science NetLinks (website) – Students will observe different objects fall from the same height to see if they reach the ground at the same time. They will also roll marbles of different sizes down an inclined plane to see if they reach the bottom at the same time.
Challenge students to devise as many ways as possible to move a heavy object (thick book) from one place to another. Provide different tools for students to employ in this task, such as a wagon, pulleys, wheels, tubes, string, sticks, etc.
