The researchers thought of trying to come up with a makeshift solar cooker in order to test if this way of cooking may be effective and useful in substituting for a frying pan and a stove. The solar cooker may be a possible alternative when cooking outdoors under the heat of the sun. It could also be a huge energy saver and a safer way of cooking, avoiding hazards such as burns. The researchers have picked the safest and easiest procedure and materials in making a solar cooker so that teenagers or even

Rationale * The researchers arrived at this kind of problem stumbling upon the topic of solar power and how much heat the sun’s rays can produce. * The researchers, as a group think that this is of big significance since global warming is indeed a serious problem in the world, in line with this, usage of energy is one of the factors that concerns this, and as students, investigating on this may be a way of helping out. They also thought that this would be a fun and innovative experience especially since this is not something you see or do every day. * PROBLEM: Can we cook food by using a mirror and sunlight? * HYPOTHESIS: * H1: If heat is produced once the sun’s rays are reflected through the mirror to the food attempted to be cooked, then we can cook food using a mirror and sunlight. * H2: If the heat coming from the sun is not enough as compared to the heat coming from the gas range or electric stove, then we cannot cook food using only a mirror and sunlight. * OBJECTIVES OF THE STUDY: * The researchers’ main objective is to be able to come up with a successful investigation and prove that it is indeed
