  • Pizza Box


Your mission
Your Mission

  • To design a solar oven that will create the most thermal energy in 45 minutes using common supplies (cardboard boxes (shoe box, pizza box, larger box, etc.) tin foil, plastic wrap, newspaper, etc.)

  • You must work in groups of 3 or 2 (need team name)

  • You will calculate volume of oven (minimum of 1,000cm3, joules of energy converted, and power of oven

  • You can choose to bring ingredients from the provided recipes (only) to make something for your group/self

Provided items
Provided Items

  • Tin foil (about 4 sheets (8.5x11))

  • Plastic wrap (about 4 sheets of 8.5x11)

  • 2 sheets black paper (which I would like back at the end)

  • Glue, staples, tape (not very strong)

Items your team must provide
Items Your Team Must Provide

  • The container (be creative!)

  • Extra tin foil (if needed)

  • Extra plastic wrap (if needed)

  • Insulation (if needed)

  • Substitutes for any of the above materials (for example: if you want plexi-glass or something more heavy duty then plastic wrap)

  • Any pre-cooked food items (basically we are only melting or re-heating foods for safety reasons, must come packaged)


  • Please use caution when cutting cardboard, especially with sharp scissors or exacto knives

  • Please only bring food that is pre-cooked and packaged

Heating systems
Heating Systems

  • Heating systems vary depending on climate

  • Before only stoves/fires used to heat: but is a slow process

Forced air systems
Forced Air Systems

  • Furnace warms air, then spreads air using ducts and vents

  • Cool air is

    returned to be

    heated again

  • Most common

    in US

Radiator systems
Radiator Systems

  • Closed metal container with hot water or steam

  • Through conduction, thermal energy passed to the surrounding air

Electric heating systems
Electric Heating Systems

  • Electric coils in floors heat surrounding air

    by conduction,

    then convection

    currents heats the

    rest of the room

Solar heating
Solar Heating

  • Buildings use the sun’s radiation in 2 ways

    • Passive: materials easily absorb radiation and heat naturally

    • Active solar: solar cells

Passive solar heating
Passive Solar Heating

  • Need lots of south facing windows

Active solar heating
Active Solar Heating

  • Uses solar collectors, photovoltaic (PV) cells, or solar panels to create electricity or warm water to radiate heat


  • The study of how thermal energy, heat, and work are related

  • Heat and work increase TE

  • Heat can only move from warm to cold, unless work is done (think about rubbing your hands together)

Converting heat to work
Converting Heat to Work

  • Heat engine: converts thermal energy to mechanical energy

    • ME=____+_____

  • Internal Combustion Engines: fuel is burned inside cylinders and turn heat to work


    • Converts only 25% of heat to mechanical energy- 75% of heat is lost (that’s why coolant is needed!)

Heat movers
Heat Movers

  • Heat movers move TE from one location to another at a different temp

Heat mover refrigerators
Heat Mover: Refrigerators

  • Does work so that heat can move from inside refrigerators to outside

  • Needs coolant: evaporates at a low temperature

  • Liquid coolant->gas (cool)->pumped to coils in fridge and TE goes from warm to cold->warm gas compressed doing work-> becomes warmer then outside air and heat flows to outside air, process starts all over again.

Air conditioners and heat pumps
Air Conditioners and Heat Pumps

  • Air conditioners: Work like refrigerators, just does the opposite

  • Heat pump: can cool and warm air

Human coolant
Human Coolant

  • As sweat evaporates absorbs TE, taking heat away from your body
