Polk Street School’s fourth and fifth grade students discovered that science can be found in everyday places during an interactive presentation by Michael Kirschner, “The Science Dude,” as part of the Supermarket Science show. During the program, common household items found in local stores were used to explain scientific concepts and challenge students to think like scientists.
Throughout the presentation, Mr. Kirschner revealed the science behind what appeared to be magic tricks, breaking down each demonstration to show the principles at work. Students explored topics such as polymers, optical illusions, forces and topology through hands-on activities and problem-solving challenges. One demonstration featured a Styrofoam cup and clear nail polish remover, helping students observe how different materials react when combined. Students also explored the mathematics and science of knots, learning about topology and attempting to tie a knot in a rope without letting go of either end.
One highlight was the “Dare to Fail” challenge, which encouraged students to make predictions, test ideas and learn from unexpected outcomes. Students discovered that failure is often an important part of the scientific process and that experiments do not always go as planned. According to Mr. Kirschner, the demonstration succeeds only about 80 percent of the time and requires a book to be moved at just the right speed in order for an egg to fall into a cup of water.
By connecting scientific concepts to familiar items found in supermarkets and around the home, the presentation made science both accessible and exciting. Sponsored by the PTA, the program was presented as part of the school’s Cultural Arts program.
