Strength of Magnets Why do you think magnet strength is important to our maglev system design?

1. Strength of Magnets Why do you think magnet strength is important to our maglev system design? How could we figure out how strong a magnet is?

2. Strength of Magnets Which magnet had the strongest magnetic field? Which had the weakest? How do you know? What do you predict would happen if the paper clip was heavier? Lighter? What do you predict would happen if the paperclip was made of a different material? How will this activity help with the design of your maglev transportation system? Do you think using more magnets in your design will always make your design better? Explain. Do you think it matters how close together or far apart you place your magnets on the maglev track? Explain.

3. How can we use our knowledge of the properties of magnets, the Engineering Design Process, and our creativity to design a maglev transportation system? • What are the main parts of our maglev transportation system? • Is a system a type of technology? Explain. • How will we know whether the objects transported by our maglev system are being transported safely? • How will we know whether the objects transported by our maglev system are being transported efficiently? • How should we judge the success of our designs?

4. Reflection What properties did you observe in Magnetic Sailing that will help you with your design? What properties did you observe in Levitating Magnets that will help you with your design? How did the masking tape, stiff paper, and foam affect the height of the levitating magnets? How will that help with your design?What properties did you observe in Magnetic Strength that will help you with your design? What step of the Engineering Design Process do you think we used when exploring the properties of magnets? Why?

5. All engineers operate under certain rules or requirements when they are designing, called criteria. They also face restrictions called constraints.

6. Use the bag of sample materials to complete Engineering Design Process: Ask!

7. Engineering Design Process: Imagine! • Brainstorm TWO different maglev transportation system designs. • What will the maglev vehicle look like and what materials will you use? • What will the maglev tracklook like and what materials will you use? • Where will you place the magnets on the vehicle and on the track? • How will you arrange the poles of the magnets?

8. Placemat Consensus to Share Ideas Draw a large rectangle in the center of the paper. Divide the outer portion of the rectangle into the number of members in the group. Record you ‘plan’ including an illustration of your components and how they will complete task in your section. Each person shares their solution to the problem. The team discusses the benefits of each design and chooses one design, or creates a new one design with features of more than one. Record the final solution to the problem in the center rectangle.

9. Engineering Design Process: Plan! • You are limited on the amount of supplies. The maximum amount is listed below: • 1 roll of masking tape • 3 sheets of stiff paper • 3 foam trays • 4 bar magnets • 5 ring magnets • 4 disc magnets • 4 strip magnets • 2 paper cups

10. Reflection Describe your maglev transportation system design. What materials did you use? Why did you choose those materials? How many weights could your system transport? Did your system transport the weights safely? How do you know? What parts of your system worked well? How do you know? What parts of your system did not work well? Why?
