Listening (10 minutes)

The solar system contains the Sun and all the objects that orbit around it. These objects are planets, asteroids, comets, and other celestial objects. It was formed more than 4 billion years ago and contains eight planets. The closest four planets to the Sun are rocky planets and the other four are made of gas and are much bigger. The rocky planets, which are Mercury, Venus, Earth, and Mars, are called the inner planets because they are closer to the Sun while the other four planets, which are Jupiter, Saturn, Uranus, and Neptune, are called the outer planets because they are much further from the Sun. Between the fourth and the fifth planet there is an asteroid belt made of a huge number of asteroids of different shapes. The hottest planet is Venus although it is not the closest planet to the Sun, the closest planet to the Sun is Mercury. The eight planets have at least 176 moons. The Sun is the biggest object in our solar system and you can fit one million Earths inside it.

Answer the questions by marking the correct answer with “C”. (5 minutes)

Writing (15 minutes)

Write using your own words everything you have learned about the solar system.



Asking questions about the solar system might look simple but it is not. They probably never heard the word “Earth” before. Choose the questions you want to ask them and prepare pictures. I did it with 10 year old learners (Vietnamese) and it went really well. They seem to enjoy learning about these things and definitely they enjoyed watching the photos I showed them.

Unlocking vocabulary

Teach them vocabulary using a picture of the solar system. You may want to help them pronouncing correctly the names of the eight planets.
Have on the whiteboard the matching exercise and ask learners to come to the board and draw lines between the words and their corresponding definitions. You may want to give them a few minutes to complete the task in pairs before coming to the board.


Have the picture of the solar system projected on the board while reading the text for your students. Point to the objects that you are reading about so they can understand better. Read for them twice (or even three times) before asking them to complete the multiple choice task.


Ask learners to write a short paragraph about our solar system using their own words. Tell them that they can use the multiple choice exercise for help.
