Content Source:

PBS
Type: Interactive/Game

Overview:

In this blended lesson supporting literacy skills, students watch videos about gravity and investigate the motion of falling objects on Earth and on the Moon. They examine how the force of gravity acts on falling objects and how air resistance counteracts gravity. This resource is part of the Inspiring Middle School Literacy Collection. This lesson is a great resource to use to give students background information on gravity and forces before they conduct a test of a falling object.

Unpacked Content
Scientific And Engineering Practices:
Constructing Explanations and Designing Solutions
Crosscutting Concepts: Cause and Effect
Disciplinary Core Idea: Motion and Stability: Forces and Interactions
Evidence Of Student Attainment:
Students:
  • Design a test to modify the speed of a falling object.
  • Conduct a test to modify the speed of a falling object.
  • Collect and record data including data before and after the modification is added.
Teacher Vocabulary:
  • gravity
  • design
  • conduct
  • gravitational force
Knowledge:
Students know:
  • The gravitational force exerted by Earth on objects is directed downward towards the center of Earth.
  • How an engineering design process is used to design and conduct a test.
  • The properties (surface area, substance, weight) of different materials used to modify the speed of a falling object will affect the fall.
Skills:
Students are able to:
  • Apply scientific ideas to solve design problems.
  • Generate and compare multiple solutions to a problem based on how well they meet the criteria and constraints of the design solution.
Understanding:
Students understand that:
  • A device added to a falling object can cause the speed to be modified.
