Science - 3rd Grade
Lesson Plans

Standard 4

Students will understand that objects near Earth are pulled toward Earth by gravity.

Objective 1

Demonstrate that gravity is a force.

• It's A Weighty Matter
  This activity will help students understand weight, mass and gravity.
• TRB 3:4 - Investigation 1 - I'm Falling For You!
  In this activity, students will experience gravity just like Galileo did during his experiments.
• TRB 3:4 - Investigation 2 - Jump
  This activity has students jump with and without weights. Their data should reveal that gravity has more of a pulling force with heavy objects that are on the ground than light objects on the ground.
• TRB 3:4 - Investigation 3 - Draggin' Me Down
  Students will discover that gravity effects objects that they roll up a ramp.
• Weighing In
  This classroom activity will help students understand gravity.
• Weighing in
  Gravity is a force that has pulling power and keeps everything pulled toward the Earth. To overcome the force of gravity, another force is needed. A Slinky and rubberbands are used in investigating weight and its relationship to gravity.
