Notes for Teachers

  • Context: This lesson takes place in a classroom for one or more hours
  • Students may work in small groups of 2-4.
  • An emphasis on the target product (a functioning basic motor)
  • Creative solutions should be encouraged
  • Facilitate student reflection on why and how Frank Einstein encourages readers to question the way things work and to discover how they, too, can experiment with motors.

List of Materials:

  • 1 AA Battery
  • 1 Pack Neodymium Disc Magnets
  • 1 Copper Wire (about 20 cm)

Picture Book (or video read-aloud)-How Does an Electric Motor Work?

Science Standards:

4.P4U1.1: Develop and use a model to demonstrate how a system transfers energy from one object to another even when the objects are not touching.

4.P4U1.2: Develop and use a model that explains how energy is moved from place to place through electric currents.

Science and Engineering Practices

  • ask questions and define problems
  • develop and use models
  • plan and carry out investigations
  • analyze and interpret data
  • use mathematical and computational thinking
  • construct explanations and design solutions
  • engage in argument from evidence
  • obtain, evaluate and communicate information

4.RL.1 Refer to details and examples in a text when explaining what the text says explicitly and when drawing inferences from the text.

4.RL.3 Describe in depth a character, setting, or event in a story or drama, drawing on specific details in the text (e.g., a character’s thoughts, words, or actions).

4.W.7 Conduct short research projects that build knowledge through investigation of different aspects of a topic.

4.SL.1 Engage effectively in a range of collaborative discussions (one-on-one, in groups, and teacher-led) with diverse partners on grade 4 topics and texts, building on others’ ideas and expressing their own clearly

Objective(s):

Today we will explain how to build a simple electric motor and study how simple changes affect the motor's rotation.

Today we will describe a character using details from a story.

Today we will collaborate and communicate effectively with our peers to complete an engineering design challenge.

Today students will be able to design and engineer a magnetic field to make a simple motor.

What is a Simple Electric Motor?

8 of 13

Simple Electric Motor

Electric motors are devices that convert electrical energy into mechanical energy (electricity into motion). Motors take the electrical energy from an electricity source, such as an outlet or battery, and change that energy into something that spins, moves or does some sort of work.

Hands-On Activity Instructions

In a group of 2-4, engineer a a magnetic field to make a simple motor.

Constraints:

  • 1 AA Battery
  • 1 Pack Neodymium Disc Magnets
  • 1 Copper Wire (about 20 cm)
  • 15 minutes

11 of 13

How do we assess our work?

  • We field test our invention
  • We seek feedback
  • We iterate and repeat

We evaluate our final iteration’s ability to meet requirements and stay within constraints

Assessment

Test your motor:

  • What do you need to create a motor? What does each component do?
  • Which part of the motor is the electromagnet?
  • How can you make the motor go faster?
  • What could you use the motor for?
  • Can two objects push or pull on each other without touching? How?

ELA Assessment

How is what you are doing similar to what Frank Einstein invented?

How is it different?

Describe in detail how Frank Einstein loves figuring out how the world works by creating household contraptions that are part science, part imagination, and definitely unusual.

Differentiation

One way to differentiate in this lesson is to provide some groups pictures of their motors and then have them draw arrows to show how the energy flowed through their motors.

Another option is to make the wire coils in advance and have students put together the simple motor as a group;

Remediation

Extension/Enrichment

  • Students who are successful right away can investigate how the thickness of the wire affects the motor.
  • Have students change one or more variables and suggest a design for the best motor possible.
