GPS Drawing - identify the pictures

I worked with another of the girls' 4-H clubs to make drawings using a GPS unit (between the girls they're involved in 4 different 4-H clubs, each with a different project area focus).

This group's ideas were a bit more complicated than the one I worked with previously (it was also a lot warmer so we had more time out in the field to work out details than the group I did this with back in January did).

To create these drawings is a bit like reading a map. The kids have to orientate their pencil drawing to the direction they are walking in with the GPS unit. In order for the drawings to be accurate, they need to "draw" on a large scale so that no line is closer than 10 feet to another line. The kids laid out their designs by putting people at key turning points on the open field to make the drawings. Then with the pencil drawing (which serves like a map), along with people place markers, they get the perspective needed to make these type of drawings.


One of our little friends (a younger sibling to a club member) offered G. one of his precious sticks while she had to stand as a place marker for a drawing. It was really sweet.



Even though some of the drawings are a little hard to decipher this time, it was the fault of the technology (my GPS unit is only accurate to about 10 feet and these drawings were very detailed and a few times the walking path came too close to other lines) than it was from the planning and execution of walking the path of their design. The kids did a great job problem-solving and strategically placing people around the field.

Have a guess what a group of 4-Hers might opt to draw? (See answers below)


 #1 - covered 16,500 square feet (if the kids spread out the details this one might have been a bit more accurate)


#2 - covered 21,405 square feet (this covered plenty of space for the outline but not for the details, particularly on the top right)


#3 - covered 17,750 square feet


#4 - covered 8,800 square feet


#5 - covered 10,750 square feet


#1 - stick person; #2 - pig (we have several kids in this club who are also members of the Swiners (pig) club); #3 - spiral (a much better rendition of a spiral than my girls attempted previously); #4 - star; #6 - barn door
