Year 6 Unit 2.1 Cycles in the Solar System

What is a cycle? Please read the passage below and answer the following questions:

During the day, you see the sun in the sky, and during the night, you see the moon in the sky. These events happen every day. The sun rises in the morning and sets in the evening. These events repeat again the next day. This is an example of a cycle – a complete round of events that repeats all over again.

To answer the question of why the Sun rises in the east and sets in the west, let’s study the diagram and fill in the blanks in the following passage using the helpful words provided.

The following passage and diagram provide an explanation for why we experience day and night.

The Earth rotates on its axis, which causes one part of the Earth to face the sun while the other part faces away from the sun. The part of the Earth that faces the Sun experiences daytime, while the other part experiences nighttime. It takes the Earth 24 hours to complete one rotation, which we call a day.

Questions:

How does the Earth rotate?

The following passage and diagram provide an explanation for why we experience day and night.

The Earth rotates on its axis, which causes one part of the Earth to face the sun while the other part faces away from the sun. The part of the Earth that faces the Sun experiences daytime, while the other part experiences nighttime. It takes the Earth 24 hours to complete one rotation, which we call a day.

Questions:

In which direction does the Earth rotate?

The following passage and diagram provide an explanation for why we experience day and night.

The Earth rotates on its axis, which causes one part of the Earth to face the sun while the other part faces away from the sun. The part of the Earth that faces the Sun experiences daytime, while the other part experiences nighttime. It takes the Earth 24 hours to complete one rotation, which we call a day.

Questions:

How long does it take for the Earth to complete one rotation?

To answer the question “How does the Earth move around the Sun?” we need to understand that the Earth follows a path called an orbit. One complete orbit of the Earth is referred to as one revolution, and this takes 365.25 days to complete. This is why we have a leap year every four years, where one day is added to make a total of 366 days.

Now, let’s answer the questions based on the passage:

What is one complete movement of the Earth around the Sun called?

To answer the question “How does the Earth move around the Sun?” we need to understand that the Earth follows a path called an orbit. One complete orbit of the Earth is referred to as one revolution, and this takes 365.25 days to complete. This is why we have a leap year every four years, where one day is added to make a total of 366 days.

Now, let’s answer the questions based on the passage:

What is the name of the path taken by the Earth around the Sun?

To answer the question “How does the Earth move around the Sun?” we need to understand that the Earth follows a path called an orbit. One complete orbit of the Earth is referred to as one revolution, and this takes 365.25 days to complete. This is why we have a leap year every four years, where one day is added to make a total of 366 days.

Now, let’s answer the questions based on the passage:

How many days are there in one year in our calendar?

To answer the question “How does the Earth move around the Sun?” we need to understand that the Earth follows a path called an orbit.

This is why we have a leap year every four years, where one day is added to make a total of 366 days.

Now, let’s answer the questions based on the passage:

How many days are there in a leap year?

Why does the Moon change shape throughout the month? Please read the passage and study the diagram below, then answer the following questions.

The Moon revolves around the Earth, as shown in the diagram. It takes 27.3 days for the Moon to complete one revolution. The changing shape of the Moon during different times of the month is due to different parts of the Moon being illuminated by the Sun as it revolves around the Earth. A full Moon occurs when the Earth is positioned between the Sun and the Moon, while a new Moon occurs when the Moon is positioned between the Earth and the Sun. The new Moon is not visible because the part of the Moon that is illuminated by the Sun is not facing the Earth.

Questions:

The diagram provided illustrates our solar system comprising of the Sun and eight planets. Being a star, the Sun is positioned at the center of our solar system and provides both light and heat energy for the Earth. All the planets revolve around the Sun. Kindly review the diagram and respond to the questions accordingly.

The Earth is a unique planet in our solar system because it is the only one that supports life. What are the characteristics that make it so special compared to other planets? Below are some of its characteristics:

There are various objects in our solar system, including comets. Comets are balls made up of ice and dust that revolve around the Sun. These objects are located in the outer parts of our solar system, beyond Neptune, and are too far away to be seen from Earth. However, some comets can be seen from our planet as they pass close by while orbiting the Sun. As they approach the Sun, the ice within the comet changes to gas, and the dust particles spread out, forming a very long tail. The Sun’s light reflects off the tail of the comet, causing it to glow and allowing us to see it.

Astronomical objects called asteroids are also found within our solar system. The diagram below illustrates how asteroids revolve around the Sun. Please read the passage below in order to answer the following questions.

Asteroids are large rocks that orbit the Sun and can vary in size from just a few meters to more than 200 kilometers in diameter. The majority of asteroids are located in a region of the solar system between the orbits of Mars and Jupiter, which is referred to as the Asteroid Belt. Ceres, the largest asteroid in the Asteroid Belt, is included in this region.
