Each group needs:

• 1 piece of Plexiglas (1/4-3/8 inch thickness) that will need to be cut to fit specific dimensions of each oven; alternatively, a plastic oven bag may also be used for this top layer and is easier to work with, although it does not provide as much insulation against heat loss by conduction through the clear layer
• scotch tape
• black duct tape
• 1 Granite Ware pan or regular black metallic cooking pan sized to fit each specific box. Teachers can simply standardize the box size for the entire class to avoid having to buy multiple size pans.
• foam insulation, which can be acquired at any home improvement store; supply each group with enough foam to insulate its box; alternatively, foam peanuts and newspaper are less-expensive insulation materials
• cardboard boxes of various sizes (at least 2)
• 3-4 feet of aluminum foil
• scissors; must be strong enough to cut corrugated cardbaord if utility knives are not used
• (optional) glue
• 3-4 pieces of black construction paper
• ruler
• (optional) utility knife
• food item to be cooked on metallic pan with box, such as Break and Bake Cookies (pre-made cookie dough), Bagel Bites, etc...; best if the items are pre-cooked and only require warming
• thermometer
• oven mitts (can share among groups)
• graph paper
