Design Challenge: Lesson 1In 20 minutes or less design and build a
vehicle that will move 100 centimeters.*Do not take your vehicle apart- place it
on the back counter with your card.
When you are done, open your notebook and answer these 2 questions.
How did you get your vehicle to move?What was one problem your group
encountered and how did you solve it?
Lesson 2: Technical Design
Engineers use science and math to plan, design, and construct products. They often sketch their ideas and plans before they build. They also make detailed records of their products after building them.
Using graph paper, draw a side view of your vehicle. Use colored pencils and try to be as accurate as possible. If you finish draw a top view as well.
Lesson 3: Design ChallengeTake apart your vehicle.
Your design challenge is to use a technical drawing to design a standard vehicle.
All vehicles should be the SAME.Read article “The Race That Wasn’t Run”
Lesson 4: Pulling a Vehicle
Question: How does adding weight affect the motion of a vehicle?
Prediction: (Students complete on their own)Materials: 1 standard vehicle 1 pulley system 16 small metal washers 1 large metal washers 1 bookendPlan:First you set up the pulley system on the vehicle.Pull it back on the table and hold it until one washer is on.Then test using different amounts of washers.Record data.
Lesson 4: Pulling a Vehicle (cont)DATA

Lesson 4: Testing Motion With a Load
Question: How does adding blocks change the way your vehicle moves?
Prediction:
Materials:1 standard vehicle1 falling weight system1 bookend2 blocks of wood1 timer
Lesson 4: Testing Motion With a Load (cont.)Method:First set up the falling weight system.Then add 2 blocks to your vehicle.Place ? washers on the hook until the vehicle
moves. Time the vehicle and record with a colored dot
on the data sheet. (REPEAT 5 TIMES)Repeat with 1 block. Repeat with 0 blocks.
DATA: (Glue down line plot)
Lesson 4: Testing Motion With a Load (cont.)
Claims Evidence
Conclusion: Answer the questions.Was your prediction right or wrong? What did you observe when testing various
loads?How did the vehicle move when it was loaded
with 2 blocks?How did the motion change when you
removed 1 block?

Lesson 5: Designing Vehicles to Meet RequirementsQuestion: How can I design a lunar rover to meet
design requirements? (Read Design Challenge Card for requirements)
Prediction: ]Materials:1 standard vehicle16 small washers2 blocks1 falling weight system1 timer
Lesson 5: Designing Vehicles to Meet Requirements (cont.)Plan: Write 5 sentences about how you designed
and tested your vehicle.
Lesson 5: Designing Vehicles to Meet Requirements (cont.)Data: (glue down data sheet)Conclusion: Was your prediction right or wrongTell about your results. Tell about how you tested the vehicle and how it
moved. Tell about any difficulties you had and how you
solved your problems.Describe any changes you would make and why? Next Questions/I Wonder………………………
Lesson7: Testing Rubber Band Energy1-Question: What is the relationship between the number of turns of a rubber band and the distance?
5-DATA: (Glue down chart)
2-Prediction: 6-Claims Evidence
3-Materials:1 standard vehicle 1 rubber band connected Colored dotsAdding machine tapeMeasuring tape
7-Conclusion: Answer the questions.•Was your prediction right or wrong?•How did you store energy in the rubber band?•What happens when the stored energy is released?•How does the number of turns on the rubber band affect the distance?
4-Method:First Then Next
