General Activity Information
 Activity ID: 1869 Title: Crash Test Dummies Digital Tool/Resource: Crash Test Dummies, Seatbelts, Momentum, and Airbags Web Address – URL: http://viewpure.com/y118jLg20i0?start=0&end=0 Overview: In this learning activity, students will use raw eggs and a shoe box to investigate how seat belts and airbags work together to save lives during a collision.  This activity results from the ALEX Resource Gap Project.
Associated Standards and Objectives
Content Standard(s):
 Science SC2015 (2015) Grade: 4 1 ) Use evidence to explain the relationship of the speed of an object to the energy of that object. Unpacked Content Scientific And Engineering Practices:Constructing Explanations and Designing SolutionsCrosscutting Concepts: Energy and MatterDisciplinary Core Idea: EnergyEvidence Of Student Attainment:Students: Use evidence, e.g. measurements, observations, and patterns, to explain the relationship between energy and speed.Teacher Vocabulary:Construct Evidence Energy Explanation Relative speed PhenomenonKnowledge:Students know: Motion can indicate the energy of an object. The observable impact of a moving object interacting with its surroundings reflects how much energy can be transferred between objects and therefore relates to the energy of the moving object. The faster a given object is moving the more observable the impact it can have on another object. The speed of an object is related to the energy of the object.Skills:Students are able to: Articulate from evidence to explain the observable impact of the speed of an object and the energy of an object.Understanding:Students understand that: Energy can be transferred in various ways and between objects.AMSTI Resources:AMSTI Module: Energy and Waves Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.4.1- Recognize that objects move at different speeds. Science SC2015 (2015) Grade: 4 3 ) Investigate to determine changes in energy resulting from increases or decreases in speed that occur when objects collide. Unpacked Content Scientific And Engineering Practices:Planning and Carrying out InvestigationsCrosscutting Concepts: Energy and MatterDisciplinary Core Idea: EnergyEvidence Of Student Attainment:Students: Use evidence from investigations to describe changes in energy that occur when objects collide.Teacher Vocabulary:collide relative motion relative speed relative brightness phenomenon inertia momentumKnowledge:Students know: Qualitative measure of energy (e.g. relative motion, relative speed, relative brightness) before the collision. Mechanism of energy transfer. Energy can transfer between colliding objects. Energy can transfer to the surrounding air when objects collide resulting in sound and heat.Skills:Students are able to: Plan and carry out an investigation to determine changes in energy that occur when objects collide. Identify the evidence to address the purpose of the investigation. Collect the data. Use data to provide evidence that energy is present whenever there are moving objects, sound, light, or heat and that it can be transferred from place to place.Understanding:Students understand that: Energy can be transferred in various ways and between objects.AMSTI Resources:AMSTI Module: Energy and Waves Alabama Alternate Achievement Standards AAS Standard: SCI.AAS.4.3- Identify the effect of an opposing force on a moving object.
Learning Objectives:

The students will:

• investigate changes in energy that result when objects collide.
• use evidence from their investigations to explain the relationship between the speed and energy of an object.
