Identify common materials that conduct heat well or poorly. The mitten test compares wool, cotton and foil.
The Florida's State Academic Standards for Science (NGSSS) outcome SC.4.P.11.2 (Physical Science) for Grade 4 says: “Identify common materials that conduct heat well or poorly. The mitten test compares wool, cotton and foil.” This Fieldbook unit teaches it hands-on, with everyday materials and a printable teacher guide and student sheet for every lesson. Official wording: Florida's State Academic Standards for Science (NGSSS).
Winter Science: Ice, Snow and Staying Warm Grades 3–5
Why roads get salted, which mitten really works, how a seal stays warm in icy water, and why a mouse is cosier under the snow than on top of it. Four hands-on lessons on ice, heat and insulation.
- What melts ice fastest? 50–60 min
Teams sprinkle salt, sugar and sand on identical ice cubes, leave one plain, and measure the meltwater after 20 minutes. Then they use their evidence to explain why road crews spread salt, and why salted ice actually gets colder.
- Which mitten keeps a hand warmest? 50–60 min
Teams wrap jars of warm water in wool, cotton, foil or nothing, and read a thermometer every 5 minutes to see which loses heat slowest. Then they explain what a mitten really does, and why it doesn't make any heat of its own.
- How do animals stay warm in winter? 50–60 min
Students put a hand into ice water inside a 'blubber glove' made of shortening between two zip bags, measure the difference with thermometers, and compare a lone cup of warm water with a huddle. Then they argue how blubber, fur, feathers and huddling help animals survive the cold.
- Can snow keep things warm? 60–75 min, including about 40 min outdoors
Teams build a 'den' for a jar of warm water, leave one on top of the snow and bury one underneath, and compare temperatures after 30 minutes. They also probe the snow with thermometers, then explain why voles, grouse and bears spend winter under the snow. A no-snow version uses a freezer and a snow stand-in.
