Design Challenge: Lesson 1 In 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 Challenge Take 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 bookend Plan: 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 Glue down data sheet 3-A into notebook

Lesson 4: Pulling a Vehicle (cont) Claims Evidence

Lesson 4: Pulling a Vehicle (cont) Conclusion (Answer these questions?) Was your prediction right or wrong? What made your vehicle move? What made your vehicle stop? How did the different weights change the motion?

Lesson 4: Pulling a Vehicle (cont) Next Questions/I wonder……………

Lesson 4: Testing Motion With a Load Question: How does adding blocks change the way your vehicle moves? Prediction: Materials: 1 standard vehicle 1 falling weight system 1 bookend 2 blocks of wood 1 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? Next Question/I wonder……….. Lesson 4: Testing Motion With a Load (cont.)

Lesson 5: Designing Vehicles to Meet Requirements Question: How can I design a lunar rover to meet design requirements? (Read Design Challenge Card for requirements) Prediction: ]Materials: 1 standard vehicle 16 small washers 2 blocks 1 falling weight system 1 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 wrong Tell 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 Energy 1-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 dots Adding machine tape Measuring 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 8-Next Questions/I wonder………………

Lesson 9: Designing and Building a Vehicle With A Sail 1-Question: How will a sail affect the motion of an axle driven vehicle? 5-DATA: (What are your observations) (Complete a Technical Drawing on Graph Paper.) Fold & glue down into notebook 2-Prediction:6-Claims Evidence 3-Materials:7-Conclusion: Answer the questions. Was your prediction right or wrong? What did the sail do to the movement of the vehicle? 4-Plan: Adapt your vehicle with K’nex to hold a cardboard sail. 8-Next Questions/I wonder………………

Lesson 10: Testing the Effects of Air Resistance on a Vehicles Motion (2 Days) 1-Question: What affect will the position of a sail have on an axle driven vehicle? 5-DATA: Creat Chart to document trail runs 1, 2, and 3 for each sail 2-Prediction:6-Claims Evidence 3-Materials: Car made in Investigation 9 Card board for sail Adding machine tape Red and Blue Dots 3 #16 Rubber Bands 7-Conclusion: Answer the questions. Was your prediction right or wrong? How did the sail placement affect to the movement of the vehicle? 4-Plan: Run 3 test runs with Sail #. Wind rubber band at least 10 times. Make sure you keeps the winds the same on each trail. Record Data 8-Next Questions/I wonder………………

Lesson 12: Building a Propeller-Driven Vehicle 1-Question:5-DATA: 2-Prediction:6-Claims Evidence 3-Materials:7-Conclusion: 4-Plan: 8-Next Questions/I wonder……………… Each group selects a What If statement and designs their own investigation following the Science Notebooking process outlined below.
