The Science Fair here at this school, or any other science fair, is a good place to look for interesting projects or unique solutions to questions, which is why it is my favorite event at this school. In this article, I will be describing some of my favorite Hale Science Fair projects from this year’s science fair.

A project in the material sciences section titled “Burger Time” recorded how long it takes different burger patties to rot and grow mold. The project requires three burger patties, one all natural, one organic, and one McDonalds burger patty. The hypothesis was that the organic and all natural patties would rot before the McDonalds one because the McDonalds one had preservatives. The burgers were recorded after no time, then after one week, then two weeks. Surprisingly, the McDonalds fast food burger rotted fastest and had grey spots on it by the end of the two weeks, as shown by the picture on the board, but the other two didn’t rot as much. The results show that McDonald’s has changed their burger recipe or gotten rid of the preservatives.

This one is an example of one of the many projects done on Fortnite, under behavioral sciences of course. “Does IQ affect kills in Fortnite” is a project where the student had a number of volunteers with no Fortnite experience take an IQ test. Once their IQ was taken, they had one hour to kill as many players in the game as possible, and the test does not end if they get eliminated. The hypothesis was that for every fifty IQ points the volunteer would get one kill. The conclusion proved that IQ does not affect how good you are at Fortnite, as I assumed, since people get better at video games the longer they play, so if you are really smart but are new to the game, a slightly less smart person that has played the game for a year would be able to beat you at it, since games are more skill based.

“No Place for Plastic” is a science project also in material sciences that has a goal of finding how to get rid of plastic and styrofoam in the oceans and other water bodies. The student had two glass cups of the following mixtures: normal water, water with one tablespoon of salt in it, and half full of acetone. Put one of each in shade and one of each in sun. Then take pieces of a plastic soda bottle and styrofoam in each. The styrofoam in acetone dissolved instantly, both in the shade and outside in the sun, proving a way to get rid of styrofoam. One thing a follow-up to this experiment could do is a way to get rid of all the dissolved microplastics and acetone in the water once all the large chunks are dissolved.

My project is titled “Does the Exterior Color of a House Affect the Inside Temperature”. Since Los Angeles is painting some of its streets white to keep them cool, I set up a science experiment to see if painting our houses certain colors during certain seasons will make them more energy efficient. The process was to take the outside and inside temperatures of each house after half an hour, one hour, and three hours, and then compare them. All the birdhouses I used were the same as well as the laser thermometer was always positioned at a specific distance. My hypothesis was that white would be the coolest because it reflects more heat, black would be the warmest because it absorbs more heat, all the others would be in between. I also assumed that having color on the roof only would be the same as on the walls and roof because the sun hits the roof more, but actually, I was wrong, because I did the experiment during the winter time and the sun was at an angle.

“Which has more voltage, a lemon or potato”  might sound like a weird question, but the student managed to pull it surprisingly. The procedure is to stick copper nails in the lemon or potato and measure the voltage with a multimeter. The hypothesis was the lemon will conduct more electricity because it has more juice, which contains water, that conducts electricity. At the end of the experiment, the lemon won in terms of volts, having 0.930 volts compared to the potato’s 0.909 volts. There was no benefit stated in the experiment, but I think if you were lost in the wilderness and needed just a little electricity to make an SOS call, you could use a lemon. You would still need a charger and some way to plug your phone in, but it’s an idea.

There are still countless projects I did not touch on in this article and many others. The science fair took place in the Multi-Purpose Room, the STEAM Lab, and the Library. I did not talk about any projects in the Library because during my research period, it was closed, and I ran out of time in this article.
