📖 Part 1: Read and Answer

The Water Cycle

Water moves around our planet in a never-ending cycle. When the sun heats water in oceans, rivers, and lakes, it turns into invisible water vapour and rises into the sky. This process is called evaporation. High up in the sky, the water vapour cools down and forms tiny droplets that make clouds. This is called condensation. When the clouds become too heavy, the water falls back to Earth as rain, snow, or hail. This is called precipitation. The water then flows back into rivers, lakes, and oceans, and the cycle starts again!

🔬 Part 2: Animal Groups

Sorting Animals

Scientists group animals based on their characteristics. Mammals are warm-blooded animals that feed milk to their babies and usually have fur or hair. Examples include dogs, cats, and whales. Birds are warm-blooded animals with feathers and wings, and most can fly. Reptiles are cold-blooded animals with scaly skin that lay eggs on land. Snakes, lizards, and crocodiles are reptiles. Fish are cold-blooded animals that live in water and breathe through gills. They have scales and fins to help them swim.
