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.
Evaluation is a group oral lab report video on Flipgrid. Can also be used as an individual written evaluation.
You can have students bring in items to cook also--smores, nachos, hot dogs etc.
