Let's create GPS art while learning more about the global positioning system!

Materials

First sketch a single letter or symbol that you would like to draw with the GPS receiver

Orient the picture in the direction of the field where you will make the drawing

Find the maximum dimensions for your drawing!

Turn on your receiver and walk straight down the field while the GPS receiver draws your path

Turn to find the maximum width of your drawing and record the distance

Determine a scale for your picture according to the measurements based off the field

Start at the beginning of your picture, and walk along the path you drew until the picture is complete!

What differences do you notice between the two drawings?
