NASA’s BEST Students: K – Grade 2
Design a Lunar Buggy
Time to explore! Design and build a lunar buggy.
K-2 Learners will be guided through a series of challenges that follow the engineering design cycle. Join NASA on an adventure through solving an engineering challenge to build a lunar buggy out of simple materials.
OBJECTIVE
To demonstrate an understanding of the Engineering Design Process while utilizing each stage to successfully complete a team challenge.
DESIGN CHALLENGE
To design and build a model of a Lunar Buggy that will carry equipment and astronauts on the surface of the Moon and to determine the best slope of ramp for the rover to travel the farthest distance.

PROCESS SKILLS
Measuring, designing, evaluating
MATERIALS
- General building supplies
- Meter stick
- Digital scale
- Small plastic people (i.e. Lego)
- Plastic eggs
- Pennies or washers (“cargo”)
- Wheels
- Something to use as a ramp (preferably a flat surface that would enable the buggy to roll for 25 cm or more)
STUDENT PAGES
- Design Challenge
- Ask, Imagine and Plan
- Experiment and Record
PRE ACTIVITY SET-UP
Set up a small ramp for the students to use with their Lunar Buggies. It can be made with something as simple as a large book set up on a table or a piece of wood propped up on chair.
MOTIVATE
- Show the video about the Apollo 15 Lunar Rover on the Moon: http://starchild.gsfc.nasa.gov/Videos/StarChild/space/rover2.avi
- Ask students to pay attention to the comments made about the difficulties in driving on the lunar soil.
SET THE STAGE
- Share the Design Challenge with the students.
- Remind students to ask questions and brainstorm ideas, then break into teams to create a drawing of a Lunar Buggy. All drawings should be approved before building.
CREATE
- Challenge the teams to build their Lunar Buggy based on their designs. Remind them to keep within specifications.
EXPERIMENT
- Students will let their rover roll down the ramp and record their observations.
- Students will test how much cargo weight their rovers can support by adding pennies (or washers, rocks, etc) to the plastic egg.
IMPROVE
- Students should improve their Lunar Buggy models based on results of the experiment phase.
CHALLENGE CLOSURE
Engage the students in the following questions:
- Did the cargo mass make a difference on your Buggy’s performance?
- How did the slope of the ramp affect your Buggy’s performance?
PREVIEWING NEXT SESSION
Ask teams to bring back their Lunar Buggy models for use in next session’s challenge. You may want to store them in the classroom or have the facilitator be responsible for their safe return next session.
Ask teams to think about potential landing pods for use during the next session. Tell students they will be building the landing pod out of the materials that have been available to them. The pod will be dropped from as high as possible (out a second story window, off a tall ladder, or from the top of a staircase).
