|Keywords||sturdy, vehicle, drive, motors, pulleys, Simple Machines, Engineering Design Process, ramp climbing, wheels|
|Grade Level||K, 1, 2, 3|
|Time||1 Hour Total|
|Brief Description||Students will build a vehicle that is sturdy and able to drive using motors.|
|Lesson Objectives:||- Introduce students to building vehicles using prior knowledge of sturdy building, motors and pulleys.
- Use the Engineering Design Process to accomplish the task.
- Explore pulley combinations that facilitate ramp climbing (extension).
|Materials Needed:||- LEGO Simple Machine kits.
- Makeshift ramp (board and stack of books, poster board, wooden blocks, etc.).
- Extra Batteries.
- ‘Engineer’s Planning Sheet’.
- ‘Engineer’s Final Report’ Worksheet.
|Preparation and Set Up:||- Set up a ramp.
- Make enough copies of worksheets for the class.
- Arrange students in pairs.
- Distribute LEGO Simple Machines kits.
|Extensions or Modifications:||- Have students use different sized pulley wheels to make their car drive up a ramp
without tipping back or falling off (smallest possible pulley on the motor, largest on
the axle with wheels). You will need to add the Ramp Test – the car should drive
to the top of the ramp. Students may need to add additional weight to their cars.
- Have students construct a cart that their car can pull. Have this cart pull something
- ADVANCED: Have students build a car that pulls a car up a ramp.
