I did an experiment on solar power. I covered an umbrella with tinfoil and taped it to the umbrella with clear tape. Next, I taped a wooden dowel with a whittled end to the umbrella and stuck it in the ground to keep the umbrella from blowing away. Then, I wrapped a hot dog in tinfoil and put it in a potato bag. Later, I felt the umbrella pole and drew a sharpie line around the pole where most of the sun has been reflected and taped the hot dog there. Last, I waited for it to cook.
My hypothesis was if hot air is the result of sun’s reflected light then hot dogs placed in the direct zone of reflected light will cook thoroughly. Unfortunately, my hypothesis was wrong. My experiment didn’t work because it wasn’t hot enough outside at 60 degrees Fahrenheit. I don’t think that the 3 mph wind was a factor. Even though the sun was shining really brightly, it wasn’t hot enough to get anything on the umbrella hot. The sun couldn’t get the hot dog hot enough to cook it. In the book I got the experiment from it said that it had to be at least 70 degrees Fahrenheit. If the weather outside was warmer then I think that it would’ve worked.
