Science - 3rd Grade
Students will understand the relationship between the force applied to an object and resulting motion of the object.
Demonstrate how forces cause changes in speed or direction of objects.
A demonstration of how a catapult works and an activity which asks students to build their own helps them understand the concept of force and its effect on an object.
Students will compare the forces of pushing and pulling. Students will also recognize that objects at rest will not move unless a force is applied to them.
Forces & Motion with Simple Machines
The students will be able to sort simple machines according to an
applied force --push or a pull.
Lifting the Load
Students will compare how much force is needed to lift objects without a pulley, then how much force is needed with a pulley.
Move It, Sir Isaac!
Students will learn about the laws of motion and force.
Students will complete several activities that reinforce the concept that all simple machines transfer force.
TRB 3:3 - Investigation 1 - Push and Pull
Students understand the effect of the forces of push and pull on motion.
TRB 3:3 - Investigation 2 - Zoom Balls
Students will create Zoom Balls to understand how sometimes both forces of push and pull need to be used at the same time.
TRB 3:3 - Investigation 3 - Weighty Mistakes
Students will understand the concept of "work" and the use of levers.
The Larger It Is the Harder It Falls
These activities help students understand the concept of force and the effect it has on the motion of objects.
Using Force and Motion
This is an hands on investigation that demonstrates what happens when a force is applied to an object.
