Unit 2 MagLev: How do mag-lev trains function without touching the track?

Lesson 1:

Sub questions: What do we need to know about magnets to figure out why Maglev trains are so fast?

• • Maglev Train Video

Lesson 2:

How is it possible for a 20+ ton train car to float without touching anything using magnetic forces?

• • Investigation details for the teacher.

Lesson 3:

How is it possible for a 20+ ton train car to float without touching anything using magnetic forces?

• • Modeling rubric

  • Concrete model

  • First sage model

Lesson 4:

What is the magnetic field like around a bar magnet? What is the field like between two magnets? Where is the field strongest? What is the direction of the field?

• • Investigation details for teacher

  • Here is a video of this procedure

  • Optional activity:Time permitting, have students log in to the Phet simulation on magnetic field lines around earth.

Lesson 5:

How is magnetic force related to magnetic field?

• • Modeling rubric

  • Lesson 5 model

Lesson 6:

Where does the final kinetic energy of the cart come from?

• • Magnetic Cart Railgun Video

  • Teacher sheet for lesson 6

Lesson 7:

How do you think the PE graphs you made would change if the carts were attractive?

Lesson 8:

How would you design a car and track so that the car is floating on a magnetic cushion? What is the major advantage of floating on the track?

Lesson 9:

Revisit DQ. What are 5 things that interest you about maglev trains? Can you find any objections or drawbacks to maglev train technologies?

Lesson 10:

Put together a presentation that shows their final sage model, how that influenced their design decisions and a test trial for their train
