WALT:

1. Understand what are the natural objects in the sky during Daytime.

STARTER:

Look around outside your window or balcony, look at the sky during Daytime. In Daytime, what do you see?

What do you see in the sky during Daytime?

Sky during Daytime

• Sun

• Clouds

• Rain

• Rainbow

Sun Facts (Part 1)

• The Sun is almost a perfect sphere.

• The Sun is a huge star that Earth and the other

  planets in our solar system orbit around.

• Unlike other stars, the Sun is close

  enough for us to feel its heat.

• Our Sun is just one star amongst billions of others!

• The Sun’s core is around 15 million degrees Celsius!

Sun Facts (Part 2)

• It is a huge ball of gas full of ongoing nuclear reactions which

  emit massive amounts of heat, light and energy in to space!

• The Sun’s light is so bright that it can damage your eyes if looked at directly.

• The sun is 1.4 million km wide!

• It is over a million times bigger than the

  Earth and 300,000 times heavier!

• The Sun has a staggeringly powerful gravity force

  which pulls the planets in space towards itself.

Sun Facts (Part 3)

• The Sun has a staggeringly powerful gravity force

  which pulls the planets in space towards itself. This same force keeps us all on Earth.

• The Sun is 150 million km/ 93 million miles away from the Earth.

• It takes the Sun’s light just over 8 minutes to actually reach the Earth, so what we see of the Sun right now is like a photograph of it.

• Light travels at 300,000 km per second.

Clouds (Part 1)

How Do Clouds Form?

The sky can be full of water. But most of the time you can't see the water. The drops of water are too small to see. They have turned into a gas called water vapor. As the water vapor goes higher in the sky, the air gets cooler. The cooler air causes the water droplets to start to stick to things like bits of dust, ice or sea salt.

Clouds (Part 2)

What Are Some Types of Clouds?

Clouds get their names in two ways. One way is by where they are found in the sky. Some clouds are high up in the sky. Low clouds form closer to Earth's surface. In fact, low clouds can even touch the ground. These clouds are called fog. Middle clouds are found between low and high clouds.

Clouds (Part 3)

What Are Some Types of Clouds?

Another way clouds are named is by their shape. Cirrus clouds are high clouds. They look like feathers. Cumulus clouds are middle clouds. These clouds look like giant cotton balls in the sky. Stratus clouds are low clouds. They cover the sky like bed sheets.

Clouds (Part 4)

What Causes Rain?

Most of the water in clouds is in very small droplets. The droplets are so light they float in the air. Sometimes those droplets join with other droplets. Then they turn into larger drops. When that happens, gravity causes them to fall to Earth. We call the falling water drops "rain." When the air is colder, the water may form snowflakes instead. Freezing rain, sleet or even hail can fall from clouds.

Rain

Rain is droplets of water that fall from clouds. Heat from the Sun turns moisture (water) from plants and leaves, as well as oceans, lakes, and rivers, into water vapour (gas), which disappears into the air. This vapour rises, cools, and changes into tiny water droplets, which form clouds.

Rainbow

A Rainbow is a multicoloured arc made due to the striking of light on water droplets. Rainbow is produced after the rain, by reflection, refraction and light dispersion process in droplets of water. All such events develop a light spectrum in the sky are called rainbow.
