Minds-On: What do we know about the Earth, Moon and Sun? [20 min.]

Instructions Teaching Tips

Begin with a classroom discussion to find out what students already know about the Earth, the Sun and the Moon.

Discuss each one at a time using discussion prompts such as the ones on the right. As you do so, begin to fill in the chart with words and images.

Begin with the Earth, then go on to the Sun and Moon.

As each is discussed, add the corresponding image to the chart.

Shown are labelled colour photographs of the Earth, Sun and Moon in a table.

Shown are labelled colour photographs of the Earth, Sun and Moon in a table. The table has three columns and two rows. The top row contains the labels, and the bottom row has photographs. The left photograph is labelled “The Earth.” It shows a blue and white sphere against black space. The centre photograph is labelled “The Sun,” and shows an orange, glowing sphere against black space. The right photograph is titled “The Moon, “ and shows a grey, mottled sphere against black space.

Explain to the students that next they will pretend that they are the Earth, the Moon and the Sun.

Action: Sun-Earth-Moon Active Roleplay [30 min.]

Instructions Teaching Tips

1. Day and Night Roleplay

Ask the question:

Does the Earth move? How do you know?

Young students are likely to respond “no” because to them, the Earth does not look or feel like it is moving.

Explain to students that the Earth is moving and by living on it, we are moving too!

Have students stand and form a circle. It is best for younger children if they can stand on a circle. This may be:

  • A circle printed on the gym floor
  • A chalk circle drawn on pavement
  • The edge of circular carpet

Stand in the centre of the circle and explain that the students are to imagine that you are the Sun and that each of them is the Earth. Encourage them to use the bodies to represent Earth (e.g., hold their hands or arms to form a circle).

Hold the large ball in your hands to represent the Sun.

Explain that the Sun is in the centre of our Solar System and that it shines outwards in all directions like a bright and hot glowing ball. Leave the ball on the floor in the centre of the circle, then join the circle yourself.

Explain that we see day and night on Earth because the Earth is turning on what is called its “axis”. The axis is an imaginary line that goes from the top to the bottom of the Earth.

Show students the ball on the axis and have them imagine that the ball is the Earth and the skewer is the Earth’s axis.

Turn the skewer so that they can see the ball turn. It’s a bit like spinning a top.

Have students imagine that they have an axis that goes from their head to their feet. At their spots in the circle, have the students slowly turn on their axis (turn in place) until they once again face the centre of the circle.

Tell students that when the Earth does one full turn on its axis, we call it a day.

Now, have students think about the Sun.

If you are the Earth and you are facing the Sun, what time of day do you think it is?

Help them to understand that this is midday, when the Sun is highest in the sky.

When your back is to the Sun, what time of day do you think it is?

At this point, they may understand that it is night.

Have students slowly turn again but stop them at a quarter of the way around and identify the time of day (sunset), repeat at the halfway mark (night), and the three quarters mark (sunrise).

Call out the times of day in order and have students move to those positions.

Identify to students that how they see the Sun throughout the day forms a repeating pattern.

Assessment Icon

Ask students what comes next in the pattern (e.g., Sunrise, midday, ____)

 

 

Safety Icon

Safety

Ensure that students have enough room to move around without bumping into others.

Any students who experience dizziness should not do the turning in circles part of the activity.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Language tips icon

Language

You may wish to introduce or use the word “cycle” to describe this type of repeating pattern.

2. Seasons Roleplay

Follow up the day-night roleplay with a similar activity for the seasons.

Tell students that the Earth also moves around the Sun. It does this much more slowly.

Ask the question:

How long do you think it takes the Earth to go once around the Sun?

Answers will vary, but some children may know that it takes a year, or 365 days, for the Earth to orbit the Sun.

Tell students that we call the time it takes for the Earth to go once around the Sun is called a year. A year is 365 days.

While still in the circle, have students walk around the circle. As they do so, call out the months. Once they get the idea, they can call out the months along with you.

Tell students that as the Earth goes around the Sun, that is why we have seasons.

If you are in the classroom or the gym, place the two metre sticks or tape on the floor in the centre of the circle to form a cross. Place the four seasons images into the quadrants it forms.

Shown is a colour illustration of a large X, with printed illustrations in between the lines.

Image - Text Version

Shown is a colour illustration of a large X, with printed illustrations in between the lines. The illustration is shown as if looking down at the ground. The X divides the space into four sections. Each section contains one piece of paper with a labelled illustration of a season. These are facing the outside edges of the illustration. The top centre section has an illustration labelled “Fall.” It shows trees with red and orange leaves falling to the ground. The right section has an illustration labelled “Winter.” It shows the same trees with no leaves, and snow falling. The bottom centre has an illustration labelled “Spring.” It shows the trees are still bare, but with green grass and birds in the bright blue sky above. The left section has an illustration labelled “Summer.” It shows the same trees, full with green leaves. The grass is also green and the sun is bright yellow in the sky.

Assessment Icon

Have students name the four seasons.

Designate one student to be the leader. Give this student the medium-sized ball. This ball represents the Earth. Have the children walk around the circle again. This time the leader calls out each season as they walk by. Repeat with several students.

Assessment Icon

Ask students what comes next in the pattern (or cycle) (e.g., Spring, Summer, ____, _____)

Ideas icon

Idea

It helps to watch one student as they move around the circle, calling out the months as they get to points, like the hands of a clock.

Ideas icon

Idea

Have students say this poem as they walk from season to season:

Winter, spring, summer, fall

Which do you like best of all?

3. Earth-Moon-Sun Roleplay

Ask the question:

Does the Moon move? How do you know?

Some students may have seen the Moon move during the night.

Explain to students that just like the Earth goes around the Sun, the Moon also goes around the Earth. Show the students that this time the small ball will represent the moon.

Explain that the time it takes for the Moon to go around the earth is around 1 month.

Have the students sit or stand in a circle.

Choose three students to come to the centre of the circle.

  1. Student #1 will hold the large ball. This represents the Sun.
  2. Student #2 will slowly walk around Student #1 while holding the medium-sized ball, which represents the Earth. Have the two students practice this. Alternatively have Student #2 stand inside the hula hoop and hold at waist level while walking around Student #1.
  3. Student #3 will slowly walk in circles around student #2 while holding the small ball, which represents the Moon. Alternatively have this student walk in circles around student #2 while using the hula hoop to guide their movement.

Repeat with other students in groups of three.

4. Solar Eclipse demonstration

With the final group of students from the previous activity, have the students stop in place so that the students are in a line like this. Give student #1 a flashlight.

Shown is a black and white diagram of three labelled circles in a horizontal row.
Alignment of students (©2024 Let’s Talk Science).
Image - Text Version

Shown is a black and white diagram of three labelled circles in a horizontal row. The text inside the left circle reads, “Student #1 (Sun with flashlight.)” The text in the centre circle reads, “Student #3 (Moon with small ball.)” The text in the right circle reads, “Student #2 (Earth with medium ball.”

Explain that once every few years, the Sun, the Moon and the Earth are perfectly in a line.

Sometimes when this happens, the Moon can block out the light from the Sun. When this happens, we call it a solar eclipse. Have students say this with you. When the Moon blocks all of the light, we call it a total solar eclipse.

This may not seem possible since the Sun is so much larger than the Moon, but it works because of the distance between them.

Have student #1 and Student #3 stand at such a distance that when Student #2 looks towards the flashlight, the light is blocked by the small ball.

Shown is a colour illustration of three students with different objects, standing in a row.

Shown is a colour illustration of three students with different objects, standing in a row. The student on the left is pointing a flashlight towards a small ball held by the student in the centre. The left half of the ball is white, illuminated by the flashlight beam. The right half is dark grey, in shadow. This shadow stretches from the first ball, to a larger ball, held by the student on the right. The left half of this ball is dark grey, in shadow. The right half is bright blue.

Have Student #1 and #3 stand in place while the rest of the students come to where Student #2 is standing to see the effect.

Background Information for Teachers

Solar Eclipses

What is a solar eclipse?

During a solar eclipse, the Moon casts a shadow on the Earth. This happens when the Moon passes between the Sun and Earth. As it does so, it blocks some or all of the Sun’s rays. Scientists call the area of darkness caused by an eclipse the penumbra. The darkest part of the penumbra is a small area in the centre. This is called the umbra

The solar eclipse on April 8, 2024, is a total solar eclipse. A total solar eclipse happens when the Moon completely covers and blocks the light from the Sun. The path of the penumbra will cross over Canada, the United States and Mexico.

Shown is a colour diagram of the positions of the Sun, Earth and Moon during a solar eclipse. The illustration is titled “Solar Eclipse.” It shows the Sun as a yellow circle on the left, the Earth as a blue circle on the right, and the Moon as a grey circle between the Earth and Sun. The Sun’s light is shown as a light blue cone extending from the Sun to the right towards the Earth and moon. The light blue cones of sunlight meet in between the Sun and moon, casting a circular shadow on Earth. The darkest part of the shadow is a small dot in the centre. This is the apex of the Moon’s umbra.

Shown is a colour diagram of the Sun, Moon and Earth during a solar eclipse. The Sun is shown as a yellow half-circle on the left. Earth is shown as a blue circle on the right. Between is a circle representing the Moon. The half of the moon facing the Sun is light gray and the half of the moon facing the Earth is black. A cone of dark gray extends from the Moon to the Earth. This represents the darkest part of the Moon's shadow on Earth. The area where this shadow is on Earth is labelled "Umbra". A larger pale gray cone extends from the Moon to the Earth. This represents the less dark part of the Moon's shadow on Earth. The oval area where this shadow appears on Earth is labelled "Penumbra".

On April 8th, 2024 many parts of Canada will experience a total solar eclipse. 

The eclipse will enter Canada in Southern Ontario, and continue through Quebec, New Brunswick, Prince Edward Island, and Cape Breton. The eclipse will exit continental North America on the Atlantic coast of Newfoundland, Canada, at 5:16 p.m. NDT. For those in the ‘path of totality’, daytime will turn into darkness for a short time as the moon passes in front of the Sun.

Shown is a colour map of the world overlaid with dozens of curved blue and red stripes and one pink line. Each stripe is labelled with a year, month, and day. A legend along the bottom indicates that the blue stripes represent total solar eclipses, the red annular solar eclipses, and the pink a hybrid solar eclipse. The blue stripe labelled “2024 April 8” is thin. It curves from the South Pacific ocean, up across Mexico, through the eastern United States and into southern Ontario, Quebec and through the Atlantic provinces. It ends in the north Atlantic ocean, about ¾ of the way between the island of Newfoundland and the coast of France.

Here comes a … Solar Eclipse (poem)
When the Sun is up,
it gives us light.
That’s how we know
it’s day not night.
When the Sun is down,
the people say,
“Hello to night and
goodbye to day”.

But sometimes
when the Sun is high,
A strange thing happens
in the sky.
The sky turns dark,
just like at night,
the people wonder,
“Where is the light?”

The Moon just wants
a little fun.
And so it sneaks up
on the Sun.
It blocks the Sun
and all its light.
It makes the day
look just like night.

The people say,
“Oh, what a sight!”
and yet for some,
it is a fright.
“Don’t be afraid,
you just need tips,
for safely watching
an eclipse.”

Special glasses
you can wear,
that keep your eyes safe
from the glare.
You can also
look around,
at cool shadows
on the ground.

So now you know
just what to do,
when an eclipse
is passing through.
It really is
a sight to see.
So, let’s get ready -
you and me!

Mathematical Thinking

  • Talk about the geometric shapes explored during the lesson (e.g., circles, spheres, crescent shapes, etc.).
  • Have students draw and talk about the cycles of day and night and seasons.

Computational Thinking

  • Students develop the computational thinking skill of abstraction when they make models, such as those using objects to represent objects in space.
  • Students develop the computational thinking skill of pattern recognition when they identify and continue patterns such as night and day and seasons.
  • Students develop the computational thinking skill of logical thinking when they make predictions about the position of planets, how objects move, etc.
  • Students can help Lenny and Lexie get ready for the eclipse in this fun unplugged coding activity.

Indigenous Perspectives

Physical Education 

  • Have students continue to practice the movement of the Earth, Moon and Sun in groups of three.
