Fun science games for year 2

Each plant part has a distinct job, and roots, stems, leaves, flowers, and seeds work with sunlight, water, and air to help the whole plant live, grow, and begin a new generation.

Weather clues such as clouds, temperature, wind, and repeating observations help us describe current conditions, prepare sensibly, and make simple forecasts that are predictions rather than promises.

Palaeontologists identify dinosaurs by comparing combinations of fossil features—such as skulls, horns, plates, claws, limb proportions, and tails—rather than guessing from one bone.

A living thing passes through stages in a particular order, and reproduction links the adult stage to a new generation so the pattern repeats as a life cycle.

A biome's long-term temperature and rainfall shape its vegetation, which determines which plants, animals, and food chains can survive there.

The ocean changes in zones with depth: sunlight fades, temperature falls, and pressure rises, so animals need different adaptations to live at different depths.

As altitude increases, Earth’s air gets gradually thinner: birds and airplanes need enough air, balloons rise into thin air, and satellites orbit above almost all of it.

Constellations are recognizable patterns we see from Earth: their stars are real, but the connecting lines are imaginary guides, and hemisphere and season change which patterns are easiest to find.
