EXTRACTING IRON FROM BREAKFAST CEREAL

By Owen Reuther and Kevin Gallagher
2.

IN OUR FIRST EXPERIMENT...

  • We did an experiment that closely matched the "Science Buddies" website
  • In this experiment we went though a series of steps to try to extract iron from breakfast cereal
  • We put the same amount of cereal and water through each trial
  • This experiment involved passing blended up cereal through a bottle with a magnet on it
  • For the first experiment, we tested Cheerios, Great Grains, Honey Bunches of Oats, Fruit Loops, and Frosted Mini Spooners
3.

WE STARTED OFF WITH POURING 250 ML OF CEREAL AND WATER

INTO THE BLENDER, THEN BLENDED FOR 5 MINUTES
4.

WE POURED THE BLENDED CEREAL INTO A SMALLER CUP

THAT WAS MORE EASY TO POUR INTO THE 2L BOTTLES
5.

WE THEN TAPED A MAGNET TO

THE SIDE OF EACH OF THE FIVE 2L BOTTLES
6.

AFTER THAT, WE POURED THE BLENDED CEREAL INTO THE 2L BOTTLES

AND MADE SURE THE PASTE PASSED OVER THE TAPED MAGNET
7.

WE WAITED ABOUT 5 MINUTES THEN EXAMINED EACH BOTTLE, EACH

WITH A DIFFERENT CEREAL IN IT, AND WENT TO SEE IF WE HAD VISIBLE IRON
8.

UNFORTUNATELY... THERE WAS NO VISIBLE IRON

IN MOST OF THE CEREALS, EXCEPT FOR....
9.

CHEERIOS!!!

AS YOU CAN SEE, THERE IS SOME VISIBLE IRON AND THE BOTTOM OF THE 2L BOTTLE
10.

HOWEVER, THERE IS NO VISIBLE IRON ON ANY

OF THE OTHER CEREALS DURING THE FIRST EXPERIMENT
11.

UH OH!

SO WE TRIED A DIFFERENT EXPERIMENT...
12.

WE DECIDED TO CHANGE UP THE EXPERIMENT A BIT

WITH THIS EXPERIMENT WE GOT BETTER RESULTS

WE HAD TO CHANGE EVERYTHING IN THIS EXPERIMENT!

  • We had to include 25grams of each cereal into 250ml of water
  • Before we put it in the water, we had to crush the cereal into crumbs
  • We also used a magnet stirrer, and a capsule like magnet
  • We tested Cheerios, Total, Chex, and Corn Flakes in this experiment
14.

THROUGHOUT THE CEREAL. WHEN THE MAGNET MOVES AROUND, IT COLLECTS IRON ON IT

AS YOU SEE HERE, WE USED THE MAGNET STIRRER TO MOVE THE MAGNET
15.

IN THIS PICTURE, KEVIN IS CRUSHING THE CERIAL FOR THE NEXT TRIAL

AND OWEN IS STIRRING THE CORN FLAKES TO EXTRACT IRON
16.

THIS IS THE MAGNET CAPSULE BEFORE BEING

STIRRED IN THE TOTAL CEREAL
17.

SHOWN HERE IS THE MAGNET CAPSULE AFTER BEING

STIRRED IN THE TOTAL CEREAL!!! LOOK AT ALL THE IRON!
18.

THE CORN FLAKES HAD THE SECOND MOST AMOUNT

OF VISIBLE IRON
19.

HERE, IS THE CAPSULE THAT WAS IN THE

CHEX CEREAL!
