Have students create an attractive, economical and efficient product to protect their pet egg from a 2 meter drop.
Log in to see state-specific standards (only available in the US).
Generate and compare multiple possible solutions to a problem based on how well each is likely to meet the criteria and constraints of the problem.
Support an argument that the gravitational force exerted by Earth on objects is directed down. “Down” is a local description of the direction that points toward the center of the spherical Earth. Assessment does not include mathematical representation of gravitational force.
Define a simple design problem reflecting a need or a want that includes specified criteria for success and constraints on materials, time, or cost.
Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects. Examples of evidence for arguments could include data generated from simulations or digital tools; and charts displaying mass, strength of interaction, distance from the Sun, and orbital periods of objects within the solar system. Assessment does not include Newton’s Law of Gravitation or Kepler’s Laws.
Plan and carry out fair tests in which variables are controlled and failure points are considered to identify aspects of a model or prototype that can be improved.
