Day 178 - Kindergarteners “Protect the Popsicle” in Engineering Challenge - Mr. Musselman - Burlington Science Center

Mrs. Duncan and Mrs. Parnell wrapped up their year-long investigation of weather and temperature with a challenge putting students engineering skills to the test! Our newly developed “Protect the Popsicle” challenge pits students love for these summer treats against the ultimate source of light and heat energy, the sun!

Students in both classes investigated how heat causes many kinds of matter to melt before investigating the many kinds of shade shelters humans already use to stay cool, particularly in the summer sun!

Students then designed and constructed solutions to the challenge of keeping a popsicle frozen in the sun with the help of a shade shelter. Students then considered how to test the shelters, ultimately deciding it would be best to put them out in a sunny spot outside because “we want to be challenged.”

The results were analyzed both qualitatively and quantitatively. Teachers poured what had melted after roughly 10 minutes into a graduated cylinder and kept the frozen contents in the plastic sleeve before asking students to consider how they could tell which shade shelters worked the best. Students were able to determine that their shelters worked well because “more freezepop was left in the plastic” than Mr. Musselman’s control popsicle left out in the sun. Then students counted up from their amount of melted popsicle to Mr. Musselman’s with the help of unifix cubes and other counters to determine the difference between the sunny and shaded popsicle!

Thanks to Mrs. Duncan and Mrs. Parnell for working on developing and piloting this new kindergarten engineering challenge! We are excited to share it with all of the Kindergarten teachers next year! Check out Mrs. Duncan’s blog post for even more information and pictures on how the challenge went.
