A Search For Starch By: Leo

     Hello Readers!  In Science, Rus and I are studying Botany.  In the past lesson, we did an experiment to test the starch level in several different foods.  We put the food on a plate and set out Iodine and a dropper.  The Iodine showed us which of the foods contained starch. On each piece of food, we put one drop of Iodine.  If the food turned blue, we knew that there was starch in the food, but if the Iodine remained brown, the food had little or no starch.  The results were interesting!  Foods such as pasta or hamburger rolls contained lots of starch, while foods such as pears or marshmallows contained almost none.  Here are some pictures. Enjoy!

 Above is the food BEFORE we applied the iodine.  Below is the food AFTER we applied the iodine.
