Lesson Using 6-Volt DC Hobby Motors

Sample Prompt

Create a lesson plan using two 6-volt DC hobby
motors with wheels for a 5th grade
classroom that is interested in building robots.
Assume you have a battery pack of 3 AA batteries,
wires, and a glue gun.

Sample Response

Lesson Plan: Building a Simple Robot with DC Motors

Objective:

Students will learn about basic electronics and robotics by building a simple robot using DC motors and a battery pack.

Materials:

  • 2 DC motors (as shown in the image)
  • 1 battery pack for 3 AA batteries
  • 3 AA batteries
  • 2 wheels (one attached to each motor)
  • Chassis (can be a small plastic container or cardboard)
  • Electrical tape and/or heat shrink tubing
  • Small switch (optional)
  • Connecting wires
  • Hot glue gun and glue sticks
  • Screwdriver
  • Scissors or wire cutters

Duration: About 2 hours

Lesson Steps:

1. Introduction to DC Motors and Robotics (15 minutes)

  • Explain what a DC motor is and how it works.
  • Discuss how robots use motors to move.
  • Show examples of simple robots (videos or images).

2. Safety Briefing (5 minutes)

  • Explain the importance of safety when working with batteries and hot glue.
  • Demonstrate how to safely use the hot glue gun.

3. Building the Robot (90 minutes)

Step 1: Prepare the Motors

  • Attach a wheel to each motor securely.
  • Connect wires to the motor terminals if not already connected. Red wire to one terminal and black (or blue) to the other.

Step 2: Construct the Chassis

  • Use a small plastic container or piece of cardboard as the base.
  • Attach the motors to the bottom of the chassis using hot glue, making sure the wheels can rotate freely.

Step 3: Connect the Motors to the Battery Pack

  • Attach the battery pack to the top of the chassis using hot glue or tape.
  • Connect the red wire from each motor to the red wire from the battery pack.
  • Connect the black wire from each motor to the black wire from the battery pack.
  • Optionally, include a switch between the battery pack and the motors to turn the robot on and off.

Step 4: Test the Robot

  • Insert the AA batteries into the battery pack.
  • Turn on the switch (if included) and observe the robot move.
  • If the robot doesn't move, check the connections and ensure the batteries are inserted correctly.

Step 5: Customize the Robot

  • Allow students to decorate their robots with markers, stickers, or other craft supplies.
  • Encourage students to experiment with different chassis designs and motor placements.

Wrap-Up and Discussion (10 minutes)**

  • Ask students to share their experiences building the robot.
  • Discuss what they learned about motors and robotics.
  • Talk about potential improvements and modifications they could make to their robots.

5. Clean-Up (10 minutes)

  • Ensure all materials are put away properly.
  • Make sure the classroom is tidy and free of any hazards.

Additional Resources:

  • Provide links to simple robotics projects and tutorials.
  • Suggest books or websites for further reading on robotics and electronics.

Assessment:

  • Observe students during the activity to ensure they are following instructions and working safely.
  • Assess the functionality of each student's robot.
  • Encourage students to explain how their robot works and what they learned from the activity.

This lesson plan aims to provide a hands-on, engaging introduction to robotics and electronics, suitable for 5th-grade students.
