Click the link to determine the other interesting experiments can be achieved using copper sulfate! The pre-heat group tasted burned, but had the most kernels pop. Test their skills! In this project you will learn a method for measuring how many Calories (how much chemical energy) is available in different types of food. A cork at the bottom of the large can is used to hold burning food underneath the smaller can. A less charming but more scientific explanation exists for why popcorn pops. Fold up the edges of the tin foil so youve constructed a small barge that will float and be able to hold objects inside of it. Which brand leaves the most unpopped kernels? When completing this experiment, test other chemical reactions to determine which produces the best results. Do the calculation and write your number down in the column "Qwater for 1g food". Slowly lower the charged balloon toward the sheet of tin foil, and as you close in with the balloon, the foil balls will react to the static charge and begin jumping like exploding popcorn kernels, but won't stick to the balloon. Put the foil on top of the embers. When the popcorn is done, count how many of the 100 seeds popped and how many did not pop. [9] The slits will let the steam from the popcorn release and help make the popcorn crispier, with just the right crunch. This instructable is going to be posted both in the Mad Researcher contest and also the Teachers Contest. A boat displaces a certain amount of water based on its weight and shape. Popcorn is scientifically known as Zea mays everta. Average the energy per unit weight released per individual food item over all three trials and write your value in the last column of your data table. When we talk about food energy, we also use the word Calorie (Cal) (note uppercase "C"), but it is a different unit. Why is it important? Tinfoil People Sculptures Directions: Cut from the center of the shorter edge of the piece to 1/3 of the way towards the center, these are the 'legs'. Once the paper outer covering is removed, the pan is held by an attached handle over a heat source such as a stove burner or campfire and gently agitated, causing the kernels to pop and push outward against the foil. Each copper ion gains two electrons, converting it into copper metal:Al0Al3+ + 3 eCu2+ + 2 eCu0Net ionic equation: 2Al0 + 3Cu2+2Al3+ + 2Cu0Aluminum foil is primarily made up of elemental aluminum arranged in a thin layer. We'll highlight some amazing money-saving uses in this episode of The Saving's Experiment!

As all this energy comes from the chemical reaction, the calculation will reveal the actual amount of energy released during the reaction, or the energy originally stored in the food. Tear another smaller piece of tinfoil and fold it longways. Perhaps students will come up with additional experiments to test other popping hypotheses? In no time, youll have perfectly crispy, fluffy popcornwith no drips to ruin the party. For example, if the normalized caloric content for nuts would be 2, it would inform you that these nuts contain double as many calories per gram of food than Cheerios do. It's easier done than said. The popcorn will pop until you can't hear the kernels shaking around anymore- this is when it's done. A less charming but more scientific explanation exists for why popcorn pops. Tin Foil Boat Experiments to Test with Kids After all of our talk about history and investigating the coins themselves, it was time to get down to experimenting. The gas forms bubbles that collect around the popcorn kernels. Fill a large basin with water, then cut a piece of tin foil that is 5 inches by 6 inches. The basic idea of a calorimeter is to release all the stored energy at once and capture all the released heat with a reservoir of water. What to do: Cut five pieces of ribbon: two long pieces, two medium pieces, and one short piece. Each group of kernels were heated for exactly 2 minutes in our microwave. Follow the same popping procedure used in the control experiment. Fill each jar half-way with your liquid of choice. Don't fold all the . The foil hack is compatible with any stovetop popcorn routine; all you have to do is swap out your usual pot lid for a sheet of foil. You even can use its chemical properties to fuel a device that will produce and collect powerful combustible gases. Note this value (expressed in milliliters) in your lab notebook. Create a graph listing the food items on the x-axis and the normalized caloric content on the y-axis. Place a C battery -- negative end-down -- on top of one end of the tin foil strip. Decide on the food items you would like to study. Do background research to find out the chemical composition of candle wax (paraffin). How many calories is this? You can present to students a simple experiment to prove that moisture is inside popcorn kernels. Then, while the base of the bulb is still in contact with the battery, take the free end of the tin-foil strip and touch it to the metal base of the light bulb. Heat oil until it begins to smoke. In general, if you take a solution containing ions of a metal, and put a piece of a more reactive metal in it, the ions will switch placesthe more reactive metal will go swimming in the solution, while the less reactive one will take its metallic form.
