### QUESTION 1 of 10

We live on a beautiful, unique planet. The Earth is very special because it is teeming with life. It is the only planet to have seas and oceans of 'liquid' water and an atmosphere containing oxygen.

The Earth spins on its axis once every 24 hours.

It takes 365 and a quarter days to orbit the sun and the orbit, which is an 'oval' shape (or ellipsis), gives us our seasons: spring, summer, autumn and winter.

Use that information as you navigate this worksheet.

Marcus and Carlie are learning about the Earth.

Marcus says: "The Earth is spinning as it orbits the sun, just like a spinning ball."

Carlie says: "I can't feel it spinning - so it can't be!"

Who is correct?

Marcus

Carlie

To help Carlie understand why she doesn't feel the Earth spinning, choose the correct explanation.

We get used to it.

Friction cancels the effect.

Everything on Earth is travelling at the same speed.

We are travelling at the speed of light.

How long does it take for the Earth to orbit the sun?

365 days

365 and a quarter days

100 days

24 hours

The extra one quarter of a day every year is...

the 29th of February in a leap year

added on to every other year

24 hours is the time taken for the...

sun to travel across the sky

Earth to orbit the sun

Earth to rotate on its axis

In the same 24 hours, which is also true about the moon?

The Earth orbits the moon.

The moon orbits the Earth.

the moon orbits the sun.

The moon rotates once on its axis.

How long (approximately) does it take for the MOON to ORBIT the Earth?

one day

one week

one month

one year

Carlie and Marcus need help with the meaning of these science words.

Can you help them match the word with its definition?

The students are learning that our planet is changing, especially our climate and weather patterns.

Carlie is using the internet and books to research this change which is called...

melting

heating

global warming

global warning

Which TWO from this list are EVIDENCE for global warming?

melting ice caps

destruction of the rain forests

seas and oceans warming up

burning fossil fuels (coal, oil, gas)

• Question 1

Marcus and Carlie are learning about the Earth.

Marcus says: "The Earth is spinning as it orbits the sun, just like a spinning ball."

Carlie says: "I can't feel it spinning - so it can't be!"

Who is correct?

Marcus
EDDIE SAYS
The Earth is spinning, just like the basket ball, at a speed of just over 1000 mph! (about 1600km/hour).
• Question 2

To help Carlie understand why she doesn't feel the Earth spinning, choose the correct explanation.

Everything on Earth is travelling at the same speed.
EDDIE SAYS
Objects on the Earth's surface are travelling WITH the Earth through space, so we don't feel as though we are spinning at about 1000mph - just as well, we'd feel REALLY dizzy!
• Question 3

How long does it take for the Earth to orbit the sun?

365 and a quarter days
EDDIE SAYS
Why is it 365 and a quarter days? Well, remember that we have a LEAP YEAR every fourth year? That's 366 days in a leap year (we have February 29th). That's because Earth's orbit of the sun takes 3651/4 days. Four quarters make one, so we add one day to every fourth year to make up for the missing quarters in the other three years. Make sense?
• Question 4

The extra one quarter of a day every year is...

the 29th of February in a leap year
EDDIE SAYS
The four quarter days, over four years, are put together to give us the 'extra' day in a leap year. This means that leap years come round every four years.
• Question 5

24 hours is the time taken for the...

Earth to rotate on its axis
EDDIE SAYS
Day and night are created by the spin of the Earth. Remember, the sun APPEARS to travel across the sky!
• Question 6

In the same 24 hours, which is also true about the moon?

The moon rotates once on its axis.
EDDIE SAYS
We always see the same face of the moon because it is also SPINNING at the SAME SPEED as the Earth.
• Question 7

How long (approximately) does it take for the MOON to ORBIT the Earth?

one month
EDDIE SAYS
A month, about 28 days, is the time taken for the moon to travel around the Earth. That makes it a MOONth!
• Question 8

Can you help them match the word with its definition?

EDDIE SAYS
What a mixture of words! Were there any that stumped you? Getting the difference between days and years is important (Earth's spinning and Earth's orbiting the sun). If there are any you get muddled on, there are some great videos to help you online.
• Question 9

The students are learning that our planet is changing, especially our climate and weather patterns.

Carlie is using the internet and books to research this change which is called...

global warming
EDDIE SAYS
Scientists have shown that the Earth is getting warmer because of human activity. They call this change GLOBAL WARMING or (in many ways, better) CLIMATE CHANGE.
• Question 10

Which TWO from this list are EVIDENCE for global warming?

melting ice caps
seas and oceans warming up
EDDIE SAYS
Chopping down the rainforest and producing gases by burning fossil fuels are thought to be some of the REASONS for global warming - not the evidence. The EVIDENCE is the clues which scientist use to explain their ideas. We can MEASURE the shrinking ice caps and the temperature of the oceans.
