Cold weather comes in handy for Oswego County BOCES students

Submitted by Oswego County BOCES

Oswego County BOCES Exceptional Education teacher Mary Ryan has been making the most out of the cold weather by conducting science experiments with her students.

After learning about the physical properties of water, and seeing a video on Reddit.com on how hot water freezes faster than cold water, Ryan’s class tested the theory.

When boiling water is tossed in the air, it creates a larger surface area, which then turns the water to cool droplets.

In extremely cold temperatures, these droplets freeze, and turn the boiling water into a cloud of ice crystals midair.

Sure enough, when the boiling water was tossed into the air, the water turned instantly into what looked like mist.

Students were able to see for themselves how hot water changes from a liquid to a solid as soon as it comes into contact with cold air.

Students have also been learning about air pressure, and conducted their own experiment using a Styrofoam cup.

When a Styrofoam cup is filled with water, and an index card is placed over the rim, the cup can be flipped upside down without water flowing out.

This is because the air pressure inside the cup keeps the index card in place.

Once the index card is removed, a force is felt as the air pushes the water from the cup.
