20 januari 2020If you have another magnet and cup, repeat steps 1-7 with a different cereal to compare the amount of black shavings from each (be sure you use the same amount of cereal and shake the cup for the same amount of time). Make sure it's sealed tightly. Does it move now? Add a few spoonfuls of dry cereal to your Zip-Lock bag, gently squeeze out most of the air and zip shut, then crush or smash the cereal into powder. If you move the magnet over the plate slowly, some of these same mashed pieces of cereal will move; and follow the direction route of the magnet. Iron is a crucial component of a balanced diet (there should actually be enough iron in your body to make one or two small nails), but some people might not consume enough iron naturally to sustain themselves. Tape your magnet to the bottom of your cup (on the outside). An experiment to prove that some breakfast cereals contain iron to stay healthy. Then he told us to put the magnet and brush it through the cereal. Gently rinse the cup with water then look for tiny black particles or shavings that are stuck to the bottom of the cup near the magnet. If you move the magnet over the plate slowly, some of these same mashed pieces of cereal will move; and follow the direction route of the magnet. Some, Breakfast cereals (a nutritious or "healthy" brand like "Total" is best to start with, but you may want to try several different ones; look for cereals that list "Reduced Iron" in the ingredients, avoid those that list "Ferric Orthophosphate"). We then took that cereal and milk and put it into a clear, ziplock bag. uIron-fortified cereal contains pure iron, which can be separated from a mixture of the cereal and water. It's also the most frequently used metal on the planet; it makes up most of steel, which is a mixture of iron and other ingredients. It's also the most frequently used metal on the planet; it makes up most of steel, which is a mixture of iron and other ingredients. Credits. If you don't see any black particles try pouring the cereal mix back into the cup and shaking it for a few more minutes, then check again. Share your story with Science Buddies! Yes, I Did This Project! That's right, you're eating metal in the morning! Yes, I Did This Project! Rinse you cup and then repeat steps 1-7. Open the bag and fill your small cup mostly full with the crushed cereal. Try floating a piece of cereal in a bowl of water, then holding the magnet very close.
Look closely and you might find iron… you know, the metal… the stuff used to make nails. He said "Yes" and I didn't believe him. Here’s an experiment to see if there really is metallic iron in your breakfast cereal. In this experiment you will devise a method of extracting supplemental iron from food to compare the iron content of several brands of breakfast cereal. All you need is a magnet strong enough to separate the meal from the metal. This project was adapted from a student project submitted to the Marin County Science Fair in California. Add enough water to make a soupy mix, then attach the lid. Because of this, many food manufacturers add iron to some foods to boost the average daily intake of this important mineral. You will see that some of the crumbled cereal is gearing upwards towards the magnet. All Acid/Base Chemistry Bubbles Crystals Density Food Chemisty Heat/Cold Kitchen Science Milk Chemistry Oils Phase/State Changes Polymers Soap Water.
Carefully remove the lid and pour the cereal into another cup or bowl (don't throw it away yet, you may want to reuse it). But not to worry, acids in your digestive tract can change this metallic iron into a form that is easily absorbed and used by your body. He had a magnet and he crushed cereal pieces and he put it in a jar. In this experiment you will devise a method of extracting supplemental iron from food to compare the iron content of several brands of breakfast cereal.

This project was adapted from a student project submitted to the Marin County Science Fair in California. Because iron has magnetic properties, during this experiment, a magnet is used to separate the iron particles from the cereal mixture.
