Solubility Testing with Peeps

A couple of weeks ago we started a Peeps science unit. Students worked in small groups to predict and then test the solubility of Peeps. Most people think that Peeps are primarily sugar. In fact, we read the nutrition label and the first ingredient was "sugar" and the second ingredient was "corn syrup". We all know that sugar dissolves in water. This means that Peeps should dissolve in water, right?
Wrong!
The solvents we used included water, salt water, hydrogen peroxide, ammonia, diet soda, bleach and vinegar. We were very, very careful to keep the bleach and ammonia separate and did not even store the two sets of beakers in the same room.
What happened? Well, different things depending on the solvent. Ask your child what our results were. One thing we learned for sure, NOTHING seems to dissolve the eyes on those Peep chicks!
