Storyline Narrative 8.2.3

Episode 1 Phenomenon:

Students will share experiences with and talk about the phenomenon of using the metal brake on a scooter going down a hill.  They will ask questions about why this happens.  Students will then do an online simulation that will allow them to explore the energy transfer of a person on a skateboard on a halfpipe. They will be able to explain about the change in the types of energy by the end of the activity.  

 

Episode 2: Students will explore the idea of transfer of energy by building simple rube goldberg machines.  They will identify the transfers of energy that are occuring in order to cause the motion for the machine to work.   


Episode 3 assessment: To begin the class the teacher will lead a brainstorm discussion about “What is Kinetic Energy” and then to identify things that have kinetic energy.  Remember to have the class review their definition for kinetic energy during this process. This information is logged where all of the students can see it. Each student will need to choose an object or process where kinetic energy is at play in which they can make a claim about how the kinetic energy is changing.  The performance expectation of this standard requires they provide evidence to the claim that the kinetic energy of an object changes as energy is transferred to or from a object. They will plan and conduct mini experiments to gather evidence to support their claim.  

Episode 1

Question

What causes motion to become heat?

Snapshot

Students look at the phenomenon of using the metal brake on a scooter going down a hill.  They will identify questions about why this happens and do an online simulation that will allow them to explore the energy transfer of a person on a skateboard on a halfpipe.

Conceptual Understandings

That kinetic energy becomes heat energy through friction.

What other types of transfers can happen?

 

Episode 2

Question

What other types of transfers can happen?

Snapshot

Review types of energy, watch a rube goldberg video and identify the transfers of energy present.  

Optional

Have students build a rube goldberg machine with provided materials and identify the transfer of energy present.

Conceptual Understandings

Many types of energy can be changed into kinetic energy.

What evidence proves that energy is transferred to or from an object causes kinetic energy to increase or decrease? 

 

Episode 3

Question

What evidence proves that energy is transferred to or from an object causes kinetic energy to increase or decrease? 

Snapshot

Students gather data about transfer of energy in order to make an argument that when energy is transferred to or from an object its kinetic energy increases or decreases.  

Conceptual Understandings

How to identify energy transfers that occur when energy is given to or taken away from an object.
