Science Sunday: Starchy Science

In honor of all the Thanksgiving feasting
we did this past week,
it seemed appropriate to do some Science
with our food.

So,
we decided to test different foods for starch.
All we needed was some Iodine, an eye dropper,
and a variety of different foods to test.
Each of the kiddos got two disposable plates
filled with slices of the follow foods:

Bread
Celery
Apples
Potatoes
and
Cheese Sticks
We then made predictions about
which foods we thought would contain starch
and recorded the info.

Then...
...we filled our eye droppers with iodine...
...and placed a few drops on the different foods.

If the iodine turned...
...purple on the food,
then it contained starch.
If the iodine didn't turn purple...
...then it didn't contain starch.

Our final conclusion?
Bread, Celery, and Potatoes
contain starch;
Cheese and Apples do not.

And no, we did NOT eat the foods
after they were sprinkled with iodine,
though I think Baby Girl really wanted too...

Yuck!

  1. I love this experiment. I've seen it a couple of times and every time I think, "I need to do this." When will I actually do it?
