Last week was science and engineering week.In school we were learning about food science. We tested for glucose, iron, fat, protein and starch. For the protein we got protein strips and food juices. We then got a test strip and dipped it into the food juice. We then looked on the bottle and seen what colour it matched to. For the iron we got different cereals and put them into a sandwich bag and then we sealed the bag tightly. Then we crushed the cereal with a rolling pin and then added a bit of water. Then we got a strong magnet and kept sliding it back and forth looking for iron(wee black dots).  For fat, we got a piece of brown paper and drew a circle it, then rubbed what ever it was, and held it up to the light and the parts in it are fat.  For glucose we used Benedicts solution.
