One thing we have plenty of right now in Michigan is SNOW! We have tons of clean, white, cold, fluffy snow. The kids love to play in it, build forts, and throw it on the slide to help them slide faster. This week we decided to use what nature gave us to make some yummy juice slushies. First the students poured juice into a small zipper top bag, and sealed it closed. In a larger zipper top bag they scooped snow (about two or three cups) and then added a tablespoon or two of rock salt. The sealed juice bag was placed inside the large bag, and the large bag was zipped close. The students then squished and squeezed the snowy mixture around the juice bag. They discovered that the bag got pretty cold, use of mittens was encouraged. We learned that the rock salt lowers the temperature of the snow, making the juice freeze, or turn to slush faster.After a few minutes, the students began to see and feel the changes. The juice began to turn into slush. When at their preferred slushie consistency, they discarded the outer bag, and using a straw and spoon, enjoyed the delicious slushie.
To learn more about the science behind making slushies or ice cream using rock salt, watch this Discovery Education Video Clip on Making Ice Cream. You can find a recipe for homemade ice cream here, and a recipe for Slushies here
