Hi, students! Welcome back to Primary 6 Basic Science and Technology. In our previous lesson, we learned about No previous lesson found.. Today, we’re going to learn about the Solar System.
Objectives
By the end of this lesson, you should be able to:
- Define the solar system.
- List the planets in our solar system.
- Define natural bodies in space.
- List six examples of natural bodies.
Solar System
The solar system is a fascinating place! It’s made up of the sun and all the objects that are held by its gravity, including the planets.
What is the Solar System?
The solar system is a group of celestial objects that are bound together by the sun’s gravity. The sun is a star, and it’s the largest object in the solar system. The planets orbit the sun in a path called an ellipse.
Planets in the Solar System
There are eight planets in our solar system, and they are:
- Mercury: The smallest and fastest planet, closest to the sun.
- Venus: The hottest planet, known for its thick atmosphere.
- Earth: Our home planet, with liquid water and life.
- Mars: The “Red Planet,” known for its rusty color and potential for past life.
- Jupiter: The largest planet, a gas giant with a Great Red Spot.
- Saturn: Known for its beautiful rings made of ice and rock.
- Uranus: An ice giant with a tilted axis, making it appear to rotate on its side.
- Neptune: The farthest planet from the sun, a cold and windy world.
Natural Bodies
Natural bodies in space are objects that occur naturally, like planets, stars, moons, comets, and asteroids.
What are Natural Bodies?
Natural bodies are objects in space that are not man-made. They are formed through natural processes, such as the formation of stars and planets.
Examples of Natural Bodies
Some of the most common natural bodies in space include:
- Stars: Giant balls of hot gas that emit light and heat. Our sun is a star.
- Moons: Natural satellites that orbit planets. Earth has one moon.
- Comets: Icy bodies that orbit the sun and leave a trail of gas and dust.
- Asteroids: Rocky bodies that orbit the sun, mostly found in the asteroid belt between Mars and Jupiter.
Evaluation Questions
Now that you’ve learned about the solar system and natural bodies, let’s see if you can answer these questions:
- What is the solar system?
- Can you name four planets in our solar system?
- What are natural bodies in space?
- What are some examples of natural bodies in space?
- What is the largest planet in our solar system?
- What is the hottest planet in our solar system?
Conclusion
Today, we learned about the solar system and the different natural bodies that exist in space. We learned that the solar system is made up of the sun and all the objects that are held by its gravity, including the planets. We also learned that natural bodies are objects in space that are not man-made and are formed through natural processes.
