Students love this lab! This 5E can take 3-5 days depending on how many days you allow them to refine their designs.
Students take cardboard boxes, rip them apart, tape and cover with foil into a shape that they think will heat water and/or cook.
Student assessment questions lead them to discover how solar cookers can help people with contaminated drinking water and also prevent air pollution and deforestation.
You can have students bring in items to cook also--smores, nachos, hot dogs etc.
