Light and Shadows
Why does my shadow follow me, and why is it so long in the morning? Young scientists chase their shadows, track the Sun across the day and test which things let light through.
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.
Solids, Liquids and Gases
Where does a puddle go? Why does ice float? A first look at the tiny particles that explain the stuff around us.
Evidence Lab
How do you know something is true? Students test a claim with their own measurements, find out why one result is never enough, and learn to tell strong evidence from weak.
Our Living Planet
Air, water, land and living things, and how each one depends on the others. Students build a sealed jar ecosystem to keep for a month and catch the water cycle in a bag on the window.
Pushes, Pulls and Magnets
Why a rolling ball always stops, whether a magnet can pull through a table, and how far a paper clip will jump. Three lessons on the pushes and pulls that start, stop and steer things.
Data Detectives
How fast are our reflexes? Which graph is telling the truth? Do taller people really have bigger hands? Three lessons where students collect their own measurements and find out what numbers can and can't tell you.
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.
Power Up: Where Electricity Comes From
Where does the electricity in our classroom come from, and why is it made differently in different places? Students trace the wires, build a wind machine that does real work, and weigh up solar power like an energy planner.
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.
Kitchen Chemistry
Fizzing, curdling and colour changes with things from the grocery store. Students gather evidence of new substances, weigh a reaction in a sealed bottle, and turn red cabbage into an acid detector.
