Students will model a MAGLEV train by using magnets to make it "float" or repel from the track with washers serving as "people" on their train. Students will calculate a figure of merit to compare the train's efficency. Students in grades 5-6 participating in the extended MAGLEV Challenge will use timers to record their train speed and use a more in-depth mathematical formula to obtain their figure of merit.

**Vocabulary: ** attract, figure of merit, levitate, MAGLEV, magnetic force field, north pole, repel, south pole

Performance Indicators | M1.1, Mathematical Analysis:“Use special mathematical notation and symbolism to communicate in mathematics and to compare and describe quantities, express relationships, and relate mathematics to their immediate environment.” S2.3, Scientific Inquiry:“Carry out their plans for exploring phenomena through direct observation and through the use of simple instruments that permit measurement of quantities, such as length, mass, volume, temperature, and time.” T1.1, Engineering Design:“Describe objects, imaginary or real, that might be modeled or made differently and suggest ways in which the objects can be changed, fixed, or improved.” |

Major Understandings | M1.1ac, Mathematical Analysis:• “Use plus, minus, greater than, less than, equal to, multiplication, and division signs.” • “Apply mathematical skills to describe the natural world.” S2.3a,b Scientific Inquiry:•“Use appropriate “inquiry and process skills” to collect data.” • “Record observations accurately and concisely.” T1.1c, Engineering Design:“Suggest ways the object can be made differently, fixed, or improved within given constraints.” |

Performance Indicators | PI5.1, Physical Setting:“Describe the effects of common forces (pushes and pulls) or objects, such as those caused by gravity, magnetism, and mechanical forces.” |

Major Understandings | MU5.1e, Physical Setting:“Magnetism is a force that may attract or repel a certain object.” |

Performance Indicators | T1.5, Engineering Design:“In a group setting, test their solution against design specifications, present and evaluate results, describe how the solution might have been modified for different or better results, and discuss trade-offs that might have to be made.” PI 4.4, Physical Setting:“Observe and describe energy changes as related to chemical reactions.” |

Major Understandings | T1.5a,b Engineering Design:• “Test a design.” • “Evaluate a design.” MU 4.4g, Physical Setting:“Without direct contact, a magnet attracts certain materials and either attracts or repels other magnets. The attractive force of a magnet is greatest at its poles.” |
