i WILL GIVE BRAINLYEST:::I NEED HELP SO BAD THE QUSTION IS AT THE END U JUST HAVE TO READ ALL THIS ... THE QUSTION IS AT THE END

In this task, you will use an engineering design method to create two solar ovens. Here’s one way to approach an engineering design:

Define the problem.
List the potential solutions.
Pick the best solution and build it.
Test the solution.
Improve the design.
Estimated time to complete: 3 hours

You will need these materials:

2 thermometers that reach at least 120°F (50°C)
2 boxes of any size that the thermometer will fit inside
Optional materials you might need to complete your designs:

plastic wrap
aluminum foil
paper
scissors or a box cutter
ruler
masking tape or clear packaging tape
glue
Stay safe! Work slowly and carefully with the scissors so you do not cut yourself. Handle thermometers carefully. Remember, they are breakable. Thermometers can contain hazardous materials. If you break a thermometer, ask for an adult’s assistance to clean it up. Construct all solar ovens outdoors in an open area.

Design, Build, and Test
Part A

In this activity, you will construct two solar ovens and use thermometers to determine which oven gets the hottest. What engineering problem are you trying to solve?

Engineers help people in remote areas and developing countries by designing alternative methods (to fossil fuels and electricity) for heating, cooking, obtaining fresh water and sanitation. Solar energy is often a suitable, available, inexpensive, renewable energy resource to power these technologies.
