Weather and seasons
Daily and seasonal changes, measuring weather, and climate.
Lessons
Hot and Cold: Particles on the Move
Why tires go soft in winter, why sidewalks have gaps, and how a thermometer knows. Five lessons on what heating and cooling do to the particles in everything around us.
Climate Clues
Tree rings, old weather records and what your own town's numbers say. Three lessons on how scientists tell climate apart from a cold week.
Weather Detectives
Warm winter winds, the hottest spot in the schoolyard and the last frost of spring. Students measure weather fairly and find out why farmers care so much about it.
Winter Science: Ice, Snow and Staying Warm
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.
Weather Watchers: What Will the Sky Do Today?
Is it sunny, windy or wet today, and how can we tell? Young scientists keep a class weather chart for two weeks, build wind socks to catch the wind and make a rain gauge from a bottle to measure the rain.
Keep It Cool: Ice, Insulation and Staying Comfortable
Why salt makes ice melt faster, which wrap keeps a drink coldest, how a seal and a fennec fox each keep their body temperature steady, and how to build a cool box that beats the heat. Four hands-on lessons that start from a freezer and work in any climate.
The Reason for the Seasons: Tilt, Daylight and the Solstice
Is summer when Earth is closest to the Sun? Students test the idea with real 2026 orbit distances and city temperatures from both hemispheres, walk a human orbit, graph real solstice day lengths from the Arctic to Tierra del Fuego and work out why a high Sun heats more than a low one. Nothing to buy: just the printed sheets and the room.
Living with Water: Salt, Rice and the Mekong
Science and English together, for English learners (CEFR A2–B1). Three investigations from Vietnam: how salt farmers turn the sea into salt, how rice terraces stop a mountain washing away, and how a house in the Mekong Delta stays dry in the flood season.
