Science - 3rd Grade
Lesson Plans

Standard 3

Students will understand the relationship between the force applied to an object and resulting motion of the object.

Objective 1

Demonstrate how forces cause changes in speed or direction of objects.

• Catapult Creations
  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.
• Classify Forces
  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.
• Simple Machines
  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.
