2. Grand Challenges for Engineering http://www.engineeringchallenges.org/cms/challenges. aspx Engineer the Tools of Scientific Discovery

3. Geo-Caching Challange 1.Direct navigation assistance (pre-programmed way-point) 2.Relative Position (distance and angle from first way-point) 3.Absolute Position (latitude and longitude only)

4. What do all those numbers mean??? 33.210955,-111.716712 http://maps.google.com/

5. What do all those numbers mean??? 33.210955,-111.716712 Which number indicates how far north or south you are? Which number indicates how far east or west you are? Find out!

6. What do all those numbers mean??? 33.210955,-111.716712 How far is it from the northern to the southern end of the field inside the track (in change of latitude)?

7. What do all those numbers mean??? 33.211505 -33.210445 0.001060

8. Discovery: We can use GPS to measure things! 33.211505 -33.210445 0.001060 = (approximate) length of the football field

9. What does the GPS receiver tell us? Where we are! = Position Change in Position over time = Velocity Change in Velocity over time = Acceleration Change in Acceleration over time = Jerk

10. From data to science… Hypothesis: If ________________ then ______________ because _____________________________. If a car accelerates more then it will require more maintenance because acceleration (changing speeds, making fast turns and going over bumps) puts more stress on the car’s components.

11. GPS Satellite – Receiver Model Question: How many GPS Satellites does a GPS receiver need to “see” to find its position (Latitude, Longitude and Elevation)? Hint: The only information a receiver knows from a satellite is how far away it is. Materials: –You (one person per team will be a receiver, everyone else will be satellites). –Lengths of string (used to represent a fixed distance).
