"You have to earn your way into this class," student Michael James said as he continued to work on his own solar oven.

Volunteers and mentors Lee Lang and Larry John lead a small group of fourth and fifth grade boys and girls in experimental science and math projects once a week, for an hour, usually on Tuesdays.

Two of the boys, Michael James and Garth Knutson, explained the process. "First we measure our boxes (none of the boxes are of the same size). Then we measure and cut pieces of foil to line each box and a piece of plastic to cover the opening. The foil reflects the sun, heats the interior of the box, gets hot and cooks stuff."

The plan is to make and eat s'mores at next week's session. J.D. Miller, Hannah Carlson and Gracie Hatheway were also busy creating solar ovens.

Other projects completed during the school year have been constructing terrariums, Mars rovers, catapults, and toothpick houses of their own design (only bases were glued).

Some third graders had the opportunity to have a group session earlier this year.

Finished projects are displayed in the 3-5 corridor at Cedaredge Elementary School.
