Here are the answers to fill in your worksheet.
What is a rotation of the Earth?
Rotation is when the Earth spins around on its own axis (the imaginary line going through the North and South Poles). This spinning motion creates day and night.
How long does it take for the Earth to complete one rotation?
24 hours (or 1 day)
What is a revolution of the Earth?
Revolution is when the Earth travels in an orbit around the Sun.
How long does it take for the Earth to complete one revolution around the Sun?
365 days (or 1 year)
THINKING TIME
Since Jupiter's day is only 10 hours long, this tells us that Jupiter rotates much faster than the Earth. It takes less time for Jupiter to spin once on its axis compared to Earth, which takes 24 hours.

Final Answer:
Left Column:
*
Definition: Rotation is the spinning of the Earth on its own axis.
*
Time: 24 hours
Right Column:
*
Definition: Revolution is the movement of the Earth around the Sun.
*
Time: 365 days (or 1 year)
Thinking Time Box:
This tells us that Jupiter rotates much faster than the Earth. Because Jupiter finishes a full spin in only 10 hours, while Earth takes 24 hours, Jupiter has a shorter day.
Parent Tip: Review the logic above to help your child master the concept of rotation and revolution worksheet.
