Weekly SRP Activities: A Sweet Experiment

Posted on July 20, 2020 at 12:00 AM by Elizabeth Land

Summer Reading weekly activities
This summer, we're imagining our stories every day! Come to the Tabb Library to pick up activity bags for crafts, science experiments and more. Can't make it this week? Don't worry. Activities with related videos will be available on our YouTube page. Activities without videos will be posted right here!

Summer Science: A Sweet Experiment

Today we're going to do a Hansel and Gretel experiment, because Hansel and Gretel liked candy and treats. Check out the book list below for some more juvenile fiction books about candy adventures, candy mysteries, as well as non-fiction books about candy. But unlike Hansel and Gretel's story, we will not be indulging in sweets and fighting a witch. Instead we're going to experiment with these sweet treats! Let's pretend to be Hansel and Gretel candy scientists and see if we can get our candy to dissolve.

Supplies

    The first step is to line up Skittles in a circle around the outside of a plate in whatever pattern
  • Skittles
  • a dish (white, if available)
  • warm water.

Instructions

  1. Line the skittles around the outside of the dish in any color order or pattern that you want.
  2. Then slowly add warm water to the middle of the dish.
  3. Watch and see what happens!

Understand the Science
The skittles are coated in sugar. The warm water dissolves this sugar coating and then diffuses it into the water. This sugar adds density - or weight - to the water. This weight pushes the less dense water away. The colors will not initially mix because they have similar density pushing against each other.

The water is the solvent: It can dissolve other substances. The colorful sugar on the skittles is the solute: A substance that is dissolved. 

As you saw, you have created rainbow water! Now think about how might change this experiment to test out different factors. You can try other candy—such as M&Ms or Starburst. You can also try tap water or ice water to see if it takes more or less time to dissolve the water. Check out the Experiment Ideas link before for a fun experiment to conduct with gummy bears. Have fun and feel free to share any pictures with us by emailing youthservices@yorkcounty.gov.
