General
In this lesson, students will learn about Earth's gravitational force.
Standards
NGSS:
MS-PS2-2
MS-PS2-4
Learning objective
Students will be able to explain how objects' masses and distance are related to their gravitational force.
Introduction
Warm up with a problem about weight on the moon compared to weight on Earth.
Instruction
Introduce the definition of gravity in the lesson. Discuss how all objects have gravity and mass. Bring up the scenario from the introduction and explain that although Virko the robot's weight stayed changed when he traveled from the Earth to the moon, his mass stayed the same. There will be practice problems to do as a class.
Next, discuss mass vs. gravity, as well as small and large gravitational forces. Students will talk with a partner about why Virko doesn't suddenly fly off the Earth of the sun is much more massive than Earth?
Quiz
Students will respond to ten multiple-choice and fill-in-the-blank questions.
Closing
Students will complete an exit slip that includes these questions:
1. Consider the picture below. What are the forces acting on the child (for this question, assume the child isn't moving)?
2. What is the difference between weight and mass?
