• Engineer means to invent, create, or to regulate

• Use math and science to create buildings, bridges and other structures

• Create safe highways and roads• Many different types of engineers

– Construction, structural, geotechnical, transportation, environmental, water resources

Where’s My Bus?Where’s My Bus?

This is a website that explains the Where’s My Bus. This is a useful website for people that use the bus system in Lincoln, NE. It tells you where the buses are at any given time and what time they are scheduled to be at each stop. You can show the students different routes and talk about how they can use this if they need the bus.

I taught this lesson the day after I taught distance formula so this is a good warm-up problem or you can use it mid-lesson to break up the notes and to ensure that the students know how to use the distance formula for the activity.

This is the bus route that goes to North Star high school which is the bus my students use, might want to change to fit your school.

This is a picture that John Coburn got when he traveled the bus system with a GPS tracker, this is the route that goes to North Star.

ActivityActivity

• The bus is at Point A on the map and we are at Point G. We want to help the engineers figure out how long it will be until the next bus arrives.

• Brainstorm missing factors needed to determine how long it will take for the next bus to arrive

• The bus is at Point A on the map and we are at Point G. We want to help the engineers figure out how long it will be until the next bus arrives.

• Brainstorm missing factors needed to determine how long it will take for the next bus to arrive

Missing factors are: Stop lights, speed limits, accidents, ect.
