3. A group of planets, moons, asteroids, and comets that revolve around the sun. Earth is part of the solar system.
5. A tool used to see very small objects that are too small to see with our eyes alone. It magnifies objects and helps scientists study cells and tiny organisms.
7. The force that pulls objects toward each other. It is what keeps us on the ground and makes things fall.
9. The remains or traces of plants and animals that lived long ago. Fossils can provide clues about Earth's history and the types of creatures that lived in the past.
10. The force that attracts or repels objects made of certain materials, like iron or steel. Magnets have two ends, called poles, that have different effects.
11. The genetic material found in all living things. It carries the instructions for how organisms grow and develop.
12. An optical instrument used to observe distant objects in space, such as planets, stars, and galaxies. It helps scientists study the universe.
13. A form of energy that can power machines and make light. It flows through wires and can be generated from sources like batteries or power plants.

1. A process where substances combine or break apart to form new substances. It often involves changes in color, temperature, or the release of gases.
2. The force that pulls objects toward each other. It is what keeps us on the ground and makes things fall.
3. Energy from the sun. It can be used to generate electricity or heat water. Solar panels capture sunlight and convert it into usable energy.
4. A community of living things, such as plants, animals, and microorganisms, along with their environment. They rely on each other for food and survival.
6. The process by which plants use sunlight, carbon dioxide, and water to make food. It is how plants grow and produce oxygen.
8. The condition of the atmosphere at a certain place and time. It includes things like temperature, precipitation, and wind.
