Experience Sarah’s Science Demonstration at Fair Oaks Elementary School!
Parents, teachers, and students, mark your calendars for Wednesday evenings when Meteorologist Sarah Spivey brings her science experiments to life on GMSA@9. Get ready to explore the fascinating world of science with Sarah as she explains the science behind each experiment.
Science with Sarah is a partnership between KSAT and the San Antonio Zoo (Copyright KSAT 2023 – All rights reserved). To help you conduct the experiment at home, here are the materials you’ll need:
Materials needed for experiment (Copyright 2024 by KSAT – All rights reserved.): A large bowl filled with ice water, 2 Ziploc baggies, Crisco or other vegetable shortening.
Follow these steps to conduct the experiment:
1. Fill a large bowl with ice and water.
2. Place your hand in the ice water and see how long you can keep it in there before it gets too cold.
3. Fill a Ziploc bag with some Crisco.
4. Place your hand in another Ziploc baggie, then place your bagged hand into the other bag filled with the shortening. This creates a layer of “blubber” around your hand.
5. Stick your “blubbered” hand into the ice water bath. You should be able to keep it in the ice water for a LOT longer! You should be able to stick your hand in an ice water bath for a lot longer! (Copyright 2024 by KSAT – All rights reserved.)
Marine animals such as polar bears, whales, walruses, and seals use blubber to keep them warm from icy waters. Without blubber, they wouldn’t survive so well in their environment like we do ours here on land or sea . In this experiment we used ziplock bags and shortening as a protective layer of blubber for our hands against
