Az. ELA Standards
5.RI.3:
Explain the relationships or interactions between two or more individuals, events, ideas, or concepts in a historical, scientific, or technical text, based on specific information in the text.
5.SL.1 :
Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 5 topics and texts, building on others’ ideas and expressing their own clearly.� a. Come to discussions prepared having read or studied required material; explicitly draw on that preparation and other information known about the topic to explore ideas under discussion.� b. Follow agreed-upon rules for discussions and carry out assigned roles.� c. Pose and respond to specific questions by making comments that contribute to the discussion and elaborate on the remarks of others.� d. Review the key ideas expressed and draw conclusions based on information and knowledge gained from the discussions.
Objective(s):
I can construct and test a device to show that energy can be transferred from one object to another.
Reading: Context for Lesson
Energy is a quantity that is conserved - it cannot be created or destroyed.
Energy makes things move. It makes machines go or do work. Energy comes in different forms. These include kinetic energy, potential energy, thermal energy, electrical energy, chemical energy, heat and light energy, sound energy and mechanical energy. Energy can be stored or it can be used. One form of energy can be transformed into another form, for example, a battery stores chemical energy but this energy can be changed to electrical energy. In a lightbulb, this energy changes into light and heat. When energy changes form, it is called energy transformation.
People have invented many ways to cause energy transformations to happen. For example, engineers control how electrical energy is formed and where it goes so it can be changed or transformed into light or heat energy in our homes.

How is energy being transferred in the video?
Where does the energy cycle begin?
How is /does it flow/transferred?
What reaction does it cause?
What would happen when: (effects of strength)
Can a stronger person be more or less accurate when bowling the ball?
Discussion: How is energy transferred:
Can you think of similar examples of how energy is transferred?
Think:
gas to your car to driving.
food you eat?
Toasting bread.
Energy flow in a toaster.
Review of Previous Knowledge and Making Connections
Think about the circuit we built, how does energy flow in this system?
How does a battery store energy?
How can you use your knowledge of energy transfer to build a device to demonstrate how energy is transferred?
Agenda (lesson time)
Review:
How does electricity move in a circuit?
How is an electrical circuit similar or different from the electricity we get (using electric wires that we use at home?
How can we use our knowledge to show how electricity can be transferred?
Reading: Energy Transfer
Task:
Design a device using your knowledge of electrical circuits to show how energy can be transferred .
Discuss and give examples of electrical appliances we use at home that transfer energy.
Discuss how your device can be a stepping stone for other devices to help us do work.
Communicate: Record observations about the design and how the energy is transferred by drawing a diagram (assessed).
Hands-on Activity Instructions
Assessment
Questions
What is an electrical circuit?
What causes the robot's motor to vibrate?
How does the motor make the robot move across the desk?
What do you think will happen when the switch is turned on/off?
Why might the bot stop moving even though it is still switched on?
Can you explain how the energy flowed or was transferred?
Draw and label a diagram to show how energy flowed in your bot.
Answer the following questions:
Did your bot work the first time? If not, what caused it not to work and – what changes did you make?
How long did your bot run?
Differentiation
Students will be allowed to use a diagram to explain the process they followed.
Students will be given sentence stems or frames to use to complete the activity.
Word Bank with list of vocabulary
Remediation
Extension/Enrichment
Explain how the idea can be used to make a practical tool. Design and name your tool/device.
Discuss how this tool can be functional using other forms of energy: mechanical etc.
