Native Americans believed that a spirit lived inside each kernel of popcorn. We found that the dancing popcorn experiment worked best when we used baking soda and vinegar. Ask any physicist working with a particle accelerator, x-ray or other light source about their lab equipment. How many calories is this? Step 2 Using tongs, gently. Aluminum foil is known to be a conductor of electricity, which means that electrons can move freely through the material when a charge is applied to it. Put on the rubber glove and use your gloved hand to rub the Styrofoam plate or rubber balloon on your hair or wool. Repeat the experiment multiple times for the most accurate results. Be patient, some food items like nuts might take a while to catch fire. Our top priority is student learning. So let us say that we start out with 100milliliters (mL) of water in the calorimeter. Count 100 popcorn kernels from the same bag used in the control experiment. Everyone knows popcorn is a great tasting snack, but it is also a fascinating food and great subject for your science fair or school project. You even can use its chemical properties to fuel a device that will produce and collect powerful combustible gases. Popcorn needs between 13.5-14% moisture to pop. Crimp the edges to seal it up, stab it all over with a small, sharp knife, and crank the heat. Lay out the aluminum foil and add the popcorn, oil and salt. Have your calorimeter pieces close at hand, and ready for use. It's easier done than said. Its just a theory, but then so is the Standard Model. Bibliography. To analyze your data, you will first calculate the energy captured by the water for each trial. (n.d.). The goal of this science project is to determine which food items store more chemical energy; you will determine this by burning the items and capturing the heat given off in a homemade calorimeter. Andrew is an avid photographer, who enjoys blending science and art in his work. It involves the same materials used to create a worx bomb, but instead of trapping the Hydrogen gas inside a sealed container, the gas is captured with a standard party balloon and ignited in the safest. Your homemade version will not reach the same efficiency to catch the heat released while burning the food; in other words, only a fraction of energy stored in the food will be converted to energy captured in the water and measured by your calorimeter. Add 20 popcorn kernels to the beaker and oil. When the balloon is inflated -- and before it bursts -- pinch the mouth of the balloon and remove it from the bottle. How do these types of molecules differ in the amount of energy they contain? Most scientists do not consider aluminum toxic. They then cover the top of the flask or beaker with a piece of foil and poke it to make several holes to allow the steam to escape. The initial temperature of the water is 20C. Use a test tube for this experiment. We started with a sheet of aluminum foil and cut it into a large circle. All Right Reserved. The foil spins because hot air rises. Glass bowl. Even with low efficiencies, this project will allow you to rank different kinds of food from more caloric to less caloric and will allow you to predict, with reasonable accuracy, the ratio of caloric content of different types of foods. A kernel will swell 40-50 times its original size! Place the plastic cup in the center of a disposable aluminum pie plate.
