What Is a Lunar Eclipse for Kids?

I was watching the news one day at home with my son. Suddenly I saw flash news talking about the Lunar eclipse. My son asked me what it was, and to be honest, I didn’t remember my old science books.

So instead of fibbing my way out of it (you’ve all been there), I brought out my handy friend google. I even made it interesting for him by creating a fun activity that we could do together to learn the idea.

So, below I present to you the activities we did. I hope these activities and ideas will help all parents answer the question “what is a lunar eclipse” for kids who are bright and inquisitive.

What Is A Lunar Eclipse?

Let us first understand what an eclipse is and what the types of eclipses are.

Eclipses And Its Types

In simple words, when one object in space comes under the shadow of another thing, we call it an eclipse. There are two types of eclipses: Lunar and Solar. Lunar eclipses happen all the time, while Solar eclipses are not that common.

The word Lunar means we are talking about the moon. You need to know that the moon does not have any light of its own, even though we see it shining every night.

You might wonder then, how does the moon appear so bright? Well, it simply reflects the sun’s light after the sun goes down, just like a mirror reflecting a source of light.

Now imagine what would happen if there was some way to stop the sun’s light on its way to the moon? It would become dark. That is what happens in a Lunar eclipse. Let me explain below.

How Does a Lunar Eclipse Take Place?

We know that the moon revolves around the earth, and the earth moves around the sun. Sometimes all three, the sun, the earth, and the moon, come together in a straight line. The earth then blocks the sun’s rays from reaching the moon, creating a Lunar eclipse.

Lunar eclipses are of two types:

  1. Total lunar eclipse: when the earth’s shadow fully covers the moon, it is known as a total lunar eclipse. The earth will completely block out the sun. Whatever little light the moon reflects gets distorted by the earth’s atmosphere, making it look reddish. This reddish moon is also known as a “Blood moon.
  2. Partial lunar eclipse: when the earth’s shadow partially covers the moon, it is known as a partial lunar eclipse.

Here are some activities which I did with my son to make him understand what was happening.

Activity 1:

You need an orange, lemon, and torchlight to do this activity.

Here we have to consider light from the torchlight as the sunlight, orange as the earth, and lemon as the moon.

Total Lunar Eclipse

Steps To Take

It would be best if you placed the orange and lemon on the table, keeping them eight inches away from each other facing a wall. You should turn off the lights for a better result. Now you can ask your kid, or you can take the torchlight and turn it on, keeping it a little way from the table but in the same line of the orange and lemon.

What Do We Observe?

When we turn on the light, we can see that the torch’s light is falling on the orange. We can see the shadow of the orange on the moon and the wall. No light from the torch is reaching the moon. We call this a total lunar eclipse.

Why Does This Happen?

It happens because the earth stops the light from the torch reaching the moon and completely covers it, and imposing a shadow on the moon.

Partial Lunar Eclipse

Steps To Take

In this experiment, we have to move the lemon a little away from the path of the orange; we should take care that the movement is only slight and not entirely out of the line. Now turn the torchlight on in the direction of the orange and lemon.

What Do We Observe?

We can see that the shadow of the earth is on the moon even now. But the moon is not fully covered. This state is called a partial lunar eclipse.

Why Does This Happen?

It happens because the moon is not entirely in the same line as the earth and the sun is a little deviated from the path.

The above activity will help our kids practically understand the meaning of the lunar eclipse.

Partial Lunar Eclipse

Activity 2:

If your child loves coloring and crafts, you can help it do this craft and teach it what lunar eclipse is at the same time.

What Do You Need?

You will need one white chart, scale, pencil, three white balls in three sizes-large, medium and small and some watercolors.

Steps To Take

Now ask your child to color the large ball orange indicating the sun, the medium ball blue indicating the earth, and leave the small ball colorless as the moon is white. Now make three markings on paper with some distance- one big circle, one medium circle, and one small circle in the same line in the same order and ask your child to paste the balls to the paper.

Now it is your turn to take a pencil and draw lines indicating the sun’s rays towards the earth with the scale’s help. You can ask them to color the sun’s rays to the earth in orange and rays from the earth towards the moon in light blue.

You also have to make a marking indicating how the earth covers the moon, casts a shadow on the moon, and asks them to color it in black. Once they finish coloring, you can easily explain how the lunar eclipse occurs by showing the variations in the colors of rays and shadow on the chart.

By exchanging the place of earth and moon and re-drawing the rays’ colors, you can also teach them what a solar eclipse is.

Giving practical experience to kids is important so that they understand things better. I try to explain any STEM concept with the help of experiments to make it easier for my son. With these What Is a Lunar Eclipse for Kids activities, we both had a lot of fun, and we both learned a little from these DIY experiments.
