Science through LEGO Engineering Learning About Gears
Lesson 8 Snail Car
Suggested Time One 30-minute session
Lesson Overview Students will build and program a LEGO car that uses gears to travel as
slowly as possible. The students will compete in a “snail race ”
whose car is the slowest. The last to cross the finish line will be crowned
the winner.
- Class discussion of different building methods.
- Building of sturdy car with gears. Gears must be geared down.
- Overview of programming the car to move forward.
- Snail car race.
- Recording design and race results in Engineering Journal.
Learning Objectives By the end of this lesson, students will be able to:
- Define WeDo programming terms.
- Be familiar with the WeDo programming language.
- Be familiar with gears.
- Define engineering design as the process of creating solutions to
human problems through creativity and the application of math
and science knowledge.
