The WIB-Capital Region Kitchen Science Series on April 23, 2016, at the Harford County Public Library (HCPL), Edgewood Branch was a fun and educational day. Youth Women In Bio (YWIB) presented the “Layer Magic! Rainbow in a Jar” experiment in coordination with the STEM program at Harford County Public Library.
Young ladies, ranging in age from 5 years old to high school freshmen, were guided through a fun and simple experiment in density, building a liquid rainbow by first dying liquids of different densities different colors of the rainbow with food coloring and then layering these liquids (from most to least dense) on top of each other in a clear plastic jar. Our rainbows consisted of normal household items: corn syrup, dish detergent, olive oil, water, and rubbing alcohol. After creating our “rainbows,” we compared the densities of the different liquids to solids, including sponges, wine corks, pennies, and grapes. During the experiment our YWIB volunteers talked about their own careers in the biological sciences and answered any general questions the ladies had about careers, density, or science in general.
The children had a great time and were able to take a colorful piece of science home with them. We thank all of our volunteers. Specifically, we would like to thank HCPL for advertising and hosting our event. In all, the library event provided a great opportunity to reach out to younger children in the Harford County community and educate them on future opportunities and careers in STEM. We look forward to partnering again with the HCPL in future years as part of their STEM and reading summer program.
