A teacher challenges her students to each build a solar oven using common household materials. The students will then test their designs using thermometers. What engineering problem are they trying to solve?

Climate issues associated with engineering works

Explanation:

A teacher challenging her students to each build a solar oven using common household materials is highly commendable. The students using this method will help in solving the engineering problem of climate issues.

This will help in the reduction of emission of greenhouse gases which causes global warming. Solar energy on the other hand is renewable and free from emission of such gases.
