If it is too hot to be outside, try this simple but educational activity: find iron in your food!

You may think of it largely in terms of lawn furniture and vitamins, but iron is everywhere. Not only is iron the fourth most common element in the earth’s crust, it’s also an essential part of our own blood!
The objects needed are very simple to find:
- A magnet.
- Breakfast cereal that is fortified with iron.
- Ziplock bag.
- Plastic see-through cup.
- Water.
The “Did You Know” section of the download explains the importance of iron in the blood.
Iron is naturally magnetic, and even though your blood contains iron, you can’t get a refrigerator to stick to you. That’s because the iron in your blood is spread out into particles too small to get the magnet to react. You can, however, use a magnet to separate the iron contained in some iron-rich foods.
