ScienceTEM

Science:

The study of the natural world to gain understanding

Big Idea: Magnetism & transfer of power

STechnologyEM

Technology:

Systems or tools that are created by humans

Big Idea: Maglev, magnets (electromagnets), electronic/electrical power, motor system, tools

for construction

STEngineeringM

Engineering:

Applying knowledge of the known world (science) in order to create a technology

Big Idea: Design process & exploration of engineering careers

STEngineeringM

Provide students with an opportunity to

explore the design process.

STEMathematics

Mathematics:

Measuring, analyzing, describing, predicting and communication using numbers.

Big Idea: Data collection and analysis

Maglev Engagement

Provide students with an opportunity

to see a model maglev at work.

Maglev Exploration (Engineers)

• Identify the various engineering fields.

• What jobs are needed to make the maglev? (focus on the engineering fields)

• How do you become an engineer?

Maglev–Design and Construction

You must create a working Maglev model to win the companies latest contract bid proposal. The contract is for a Magnetic Levitation vehicle to be used in the high-

speed transportation of people. In order to win the bid contest you must design, construct, test and communicate your

finding to the FRA

Constraints are important

1. Sled size2. Cabin size3. One Motor/ Propeller4. Electricity comes from

the guide way5. Motor must be mounted securely 6. Information must be

recorded and communicated effectively

Maglev–Displaying data

“My data shows that there was an increase of success in my trials. I started off poorly and

made many modifications. Each modification after trail #5 increased in distance. I finished my project be consistently getting in the mid-

80’s for distance.”
