Science · Pre-K
Children discover that some questions can be answered by trying something (Will the apple float?) while others are answered by asking someone (What is your friend's name?). They make a prediction, test which things sink or float, and tell honestly what happened, even when the result surprises them.
Science · Pre-K
Children watch things change over time: ice melts into water, a puddle dries up, a seed sprouts. They put before-and-after pictures in order, run an ice-melt race between a sunny spot and a shady spot, and learn to record what they see with drawings and marks so they can count and remember it later.
Science · Pre-K
Children name what everyday things are made of (wood, metal, cloth, paper, plastic, glass) and run two simple tests: a drip test to see which materials soak up water and which keep it out, and a look-through test to see which materials are see-through. They use what they found to pick a material for a raincoat and a window.
Science · Pre-K
Children sort everyday actions into pushes (away from you) and pulls (toward you). With a ramp simulation and a real ramp, they find that a higher ramp sends a toy car farther, then run their first fair test: same ramp, same car, only the floor changes, and the bumpy carpet stops the car sooner than smooth wood.
Science · Pre-K
Children learn that living things grow and change, while things like rocks and balls do not. They match young animals to grown-ups, put the steps of a chick's and a frog's life in order, and measure a growing plant with blocks to see that it gets taller over days.
Science · Pre-K
Children learn that a habitat is a place where an animal finds food, water and shelter. They explore three habitats close to home (a tree, a pond and the damp ground under a log), sort animals into the habitats where they live, and practise being gentle habitat explorers who look closely, count what they find and put everything back.
Science · Pre-K
Children sort daytime and nighttime, find things that give off light, and discover that a shadow appears when something blocks the light. They follow the sun's pattern across one day (low in the morning, high at midday, low in the evening, then night) and trace their own shadow to see it change from long to short to long.
Science · Pre-K
Olly's toy bunny needs a shelter from rain, wind and hot sun. Children decide what a good shelter must do, test shelters with a gentle 'rain' from a watering can and a 'wind' from a fan, compare two designs fairly and improve the one that failed by choosing a better material, using what they learned about waterproof materials.
