Read the passage: "Long ago, before electricity, people used candles and oil lamps to light their homes. Reading at night was difficult and hard on the eyes. Then, in 1879, Thomas Edison invented a practical electric light bulb. This changed the world forever. People could now light up entire rooms with the flick of a switch, making nights safer and more productive." Who invented the practical electric light bulb?

Read the passage: "Spiders are not insects — they are arachnids. Unlike insects, spiders have eight legs and two body parts. Most spiders spin silk webs to catch their prey. Spiders eat flies, mosquitoes, and other insects, making them helpful to humans. Although many people are afraid of spiders, only a small number are actually dangerous." What do most spiders use to catch prey?

Read the passage: "Rainforests cover only a small part of the Earth, but they are home to more than half of the world's plants and animals.

It is important to protect these forests for the future." What word in the text means 'the roof formed by treetops'?

Read the passage: "Water is essential for all life on Earth. It covers about 70% of our planet's surface. Most of this water is salt water in the oceans.

Where is most of the fresh water found?

Read the passage: "Maya wanted to build the tallest sandcastle on the beach. She dug a deep moat around it and decorated it with shells. Just as she finished, a big wave crashed in and washed half of it away. Maya was upset at first, but then she smiled. She had learned something important: building is more fun than having." What happened just as she finished?

Read the passage: "A food chain shows how energy passes from one living thing to another. It always starts with a plant, because plants make their own food using sunlight. A caterpillar eats the plant. A bird eats the caterpillar. A hawk eats the bird. Each step is called a link in the chain. If one link disappears, the whole chain is affected." What is each step in a food chain called?

Read the passage: "Recycling means turning used materials into new products instead of throwing them away. Glass, paper, plastic, and metal can all be recycled. Recycling saves energy, reduces pollution, and helps protect natural resources. For example, recycling one tonne of paper saves 17 trees. You can help by sorting your rubbish into the correct bins." What are THREE benefits of recycling mentioned in the passage?

Read the passage: "Long ago, before electricity, people used candles and oil lamps to light their homes. Reading at night was difficult and hard on the eyes. Then, in 1879, Thomas Edison invented a practical electric light bulb. This changed the world forever. People could now light up entire rooms with the flick of a switch, making nights safer and more productive." When was the practical electric light bulb invented?
