 * FOOD SCIENCE LABS**

= Iron in Cereal Lab =

To observe the presence of the mineral, iron, in breakfast cereal.
 * Purpose**

iron-fortified cereal resealable bag water magnet
 * Equipment**

1. Choose an iron-fortified cereal (preferably a flake-type cereal) 2. Crush one cup (250 ml) into tiny pieces and place into a resealable bag. (Alternatively, if the bag is strong enough, you may crush the cereal inside the sealed bag.) 3. Fill the bag half full with water and carefully seal the bag. Leave an air pocket in the bag. 4. Leave it to set for several hours. (You may leave it until the next class period.) 5. Lay the bag flat on the palm of your hand and drag a strong magnet over the cereal mixture. Flip the bag over and drag the magnet underneath the mixture. Slowly slosh the contents of the bag in a circular motion for 15 to 20 seconds. 6. Continue to move the magnet around and note your observations.
 * Method**

1. Observe the edges of the magnet where it touches the bag. What do you see? 2. As you move the magnet over the bag more, what do you observe?
 * Conclusions**

Why does the cereal need to be crushed and mixed with water? Redesign the experiment to compare the iron content of different kinds of cereals. How would you maintain consistency when investigating? Design a possible observation chart for someone to record his or her observations.
 * Extensions**

= Fats in Foods Lab = - Test the items by smearing the product on blank paper (or paper bag). Allow samples to dry. - Note that the samples that cause the paper to be translucent after a drying period contain fat. - Consider various items, including: margarine, butter, chips, granola, cheese slice, lard, oil, water, apple juice, cold cuts, crackers. - Use the attached observation chart to record your results.  - Observe the appearance of the item before smearing, the appearance immediately after the smear, and the appearance after the sample has dried. For each item, determine whether fat is present. - Record your calculation.
