This project explores how a solar-powered oven can cook marshmallows using sunlight. By building a simple oven with reflective surfaces and black paper to trap heat, the experiment measures how effectively sunlight can be converted into heat to melt marshmallows, demonstrating the practical use of solar energy

The project appears to be something you care so much about and this is evident in your presentation.Your ability to explain the process/concept makes your work very interesting.
Thank you for the effort you put into this project. You explored an interesting way to use solar energy and clearly showed how sunlight can be turned into heat. Nice work and good effort.
Great idea!
Great!
