General Lesson Information
 Lesson Plan ID: 34549 Title: I've Fallen....... Overview/Annotation: In this lesson, which was adapted from Gravity and Falling Objects, students predict what will happen when different objects are dropped at the same time from the same height, and then test their predictions. Next, they will observe objects of different masses being dropped and leaking cups being dropped into a bucket. The activities in this lesson will demonstrate that all objects fall at the same rate, regardless of their mass. Finally, students will predict what will happen when two balls of the same mass but different volumes--and then two balls of different masses but the same volume--are dropped at the same time from the same height.This lesson results from a collaboration between the Alabama State Department of Education and ASTA.
Associated Standards and Objectives
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).

Primary Learning Objective(s):

Learning Targets

I will be able to describe gravity as a force that exists between any two objects that have mass.

I will be able to demonstrate that all objects, regardless of their mass, fall to the ground at the same rate.
