We are an 8th grade Pre-Algebra class at Maricopa Wells Middle School in Maricopa, Arizona, U.S.A.
We are located Latitude (33) Longitude (-112).

Our city and school is in a great growth at this time. A couple years ago our middle school had 300 kids; now we has 1270 and still more are coming! We have a dress code of simple designs/plain shirts and pants, and we have a great sports program with football, volleyball, soccer, basketball, cheer, and cross country. We have a great staff and student population and we are getting excited for this well put together project...goooo Eratosthenes!!

Mrs. Gomez’ 8th Grade, 5th Hour Pre-Algebra Class

When I caught up with the class on Wednesday, September 26th, they had already been working with several days worth of sun movement measurements.When I met up with them outside their classroom, at the start of 5th hour, students were already aligning and stabilizing meter sticks that would be used as one of their tools. Underneath the sticks, they had first set down butcher paper. The stick cast the sun’s shadow on the paper and the small teams were directed by the teacher to take new measurements every 2 minutes for 10 minutes. This was the data collection phase.

Along with this and several other days of data the students are developing mathematical and statistical ways to analyze and interpret their data - to make it meaningful. The collaborative portion of this project derives from the publishing and evaluation of many class findings. The students in Mrs. Gomez’s class were viewing data submitted by students in other countries, far flung geographic locations, who are conducting the same project NOW!

Students will now work to calculate the circumference of the Earth, prepared with a good understanding of mathematics, the measurements of their simple tools and methods, and factoring in data published from a worldwide host of contributors ! They viewed data and pictures from Australia, Philippines, France and more!
