28-05 STEM - Solar Oven challenge!

The STEM Challenge for third of primary students was to build a solar oven prototype, using heat-absorbent material to create the greatest temperature and deciding the final design. The students took the prototypes outside and tested them in full sunlight for 15 minutes.
STEM
Science: key concepts such as source of energy, solar energy, and renewable energy.
Technology and Engineering: building the inside and outside of the oven following the scientific principles and using specific heat conductive material.
Mathematics: collecting and registering numerical data.
