Yes! We eat certain metals, we need them in fact. They are important for our bodies. Have you ever noticed the iron in your breakfast cereal?
The adult human body actually has enough iron in it to make two small nails!
Take a look at the crushed cereal in your bag. Examine it for traces of Fe(iron), which are dark in color. Do you have any ideas about how we could break the cereal down further, making the particles smaller?
Once you have added water to your cereal, please squish your mixture around in the bag. Be careful not to open it. Now take your magnet and rub it around over one side of the bag. Remove the magnet and look to see what is underneath.
