Overview:

Falling 101 investigates why and how things fall, and explores common student misconceptions about gravity, inertia, and air resistance.

Content Standard(s):
 Science SC2015 (2015) Grade: 5 7 ) Design and conduct a test to modify the speed of a falling object due to gravity (e.g., constructing a parachute to keep an attached object from breaking).* Unpacked Content Scientific And Engineering Practices:Constructing Explanations and Designing SolutionsCrosscutting Concepts: Cause and EffectDisciplinary Core Idea: Motion and Stability: Forces and InteractionsEvidence 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 forceKnowledge: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.AMSTI Resources:AMSTI Module: Earth: Gravity and Space Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.5.7- Identify solutions designed to reduce the effects of a falling object due to gravity (e.g., a parachute to keep an attached object from breaking).
