6/2 Title and make a list• List 3 Criteria for your maglev car

project– Must float– Motor must PUSH– Must “Look like a high-speed” vehicle– Must house a 1x1x5 inch piece of cargo– Wires must contact track behind the car

Exploring Technology - Lesson 7

• Energy is the capacity to do work.–Lifting a weight–Heating a room or material–Pushing a vehicle

• Potential energy (stored) is often converted into Kinetic energy (motion)

Energy• Energy can be used to

do work using several processes.

• Energy can be potential or kinetic

• Power is:– the rate at which energy is converted from one

form to another,– transferred from one place to another, or – the rate at which work is done.

We can walk up the steps or run. Either way, the same amount of work is done. Running does it faster and requires more POWER.

• Much of the energy used in our environment is not used efficiently.–Automobile engines < 20% efficient–Hot water heater–Electrical power plants

Conservation is the act of making better use of energy

Power Systems

• Automobile

• Airliner

Power Systems

• Locomotive

• Grain Mill

10/20 Add to yesterday’s drill• Transportation vehicles are made up of subsystems

that must function together for a system to work effectively.– Structural– Propulsion– Suspension -What holds it up in its environment?– Guidance - What helps the operator know where to go?– Control-How does the operator make it stop, go, turn?– Support

Transportation SubsystemsSubsystem Description Automobile Airliner

Propulsion What makes it “go”?

Structural Functional shape, gives it strength, aerodynamics

Suspension What holds it up in its environment?

Guidance What helps the operator know where to go?

Control How does the operator make it stop, go, turn?

Support Outside systems that enable it to function properly

3/21 Sketch and Label

• Sketch 3 shapes you might consider for you maglev car base.

• REMEMBER – Magnets must align with the original edge of the base

10/22 Answer in sentences• Identify a change you made to your maglev car

based on testing.• Describe the result of the change.

– Ex. “We removed and flipped over our front magnets because the stuck to the track. The car floated well as a result of the change”
