1. Solar Bake Off

3. PROCEDURE 1.1 st person traces a flap in the top of the box. Use the ruler and marker to measure a 1½” border around the lid, on the top of the box. 2.2 nd person carefully cut three sides of the rectangle that was just traced on the lid of the box, forming a flap of cardboard. Leave the side of the square that is along the box’s natural hinge untouched. 3.3 rd person gently folds the flap back along the uncut edge to form a crease and wraps the underside face of this flap with aluminum foil. This flap will become your reflector panel. 4.4 th person tapes it on the other side so that the foil is held firmly.

4. PROCEDURE (continued) 1.1 st person closes the flap, opens the box, and cuts a piece of aluminum foil to fit the inside bottom of the box. 2.2 nd person glues the foil to the bottom of the box and glues black construction paper on top of the aluminum foil. 3.3 rd person rolls up some newspaper, and fits it around the inside edges of the box. It should be about 1” to 1½” thick. Use tape or glue to hold the newspaper in place, but only tape it to the bottom of the box, not the lid. 4.With the box still open, the 4 th person cuts a piece of heavy- duty plastic wrap an inch larger than the flap opening on the box top, tapes the piece of plastic wrap to the underside of the box lid and pulls it tight over the opening in the box top, then tapes it down on the top. (Be sure to tape down all four sides so the plastic is sealed against the underside of the cardboard. This creates a layer of air that works as insulation to help keep the sun's heat in the box.)
