Scaling Seasons Time Vocab Seasons - Part 2
To help us better understand scientific concepts that are too far away, too big or too small to be seen.
What are scientific models used for?
The tilt of Earth's axis.
What is the reason for seasons?
Earth's rotation
What about the S-E-M system creates a day?
An imaginary line that a planet rotates on.
What is an axis?
Summer, Fall, Winter, Spring
State Earth’s four seasons.
A model that shows an object's correct size.
What is a scale model?
When Earth is tilted towards the Sun.
How is summer created?
24 hours
How long does it take Earth to rotate on its axis?
To spin on its axis.
Define rotate
The Earth is NOT tilted towards or away from the Sun. Comes after winter.
What about the S-E-M system creates spring?
Sun, Earth, Moon
Rank the following objects from largest to smallest: Moon, Sun, Earth
When Earth is tilted away from the Sun.
How is winter created?
Earth revolving around the Sun
What about the S-E-M creates a year?
To circle around another object.
Define revolve
The Earth is NOT tilted towards or away from the Sun. Comes after summer.
What about the S-E-M system creates fall?
Using a tennis ball, basketball, and a marble, Correctly identify which can be used for the Earth, The Sun, and the Moon.
Winter = less direct light and
Summer = More direct light
Compare the angles of the sun in winter vs. summer.
A year or 365 days
How long does it take the Earth to revolve completely around the Sun?
The path an object travels during its revolution.
Define orbit
There would be no seasons.
What would happen to Earth’s seasons if Earth’s axis wasn’t tilted?
No, the Sun should be larger than the Earth for the model to be to scale.
Would a model of the Sun and Earth be to scale if the Sun were smaller than the Earth? Explain your answer.
It is colder because in winter the Earth is tilted away from the Sun.
Explain how it is colder in the winter if Earth is closer to the Sun.
The Moon revolving around the Earth.
What about the S-E-M system creates a month?
......
Pick up an object and model it rotating and revolving.
It is warmer in the summer because Earth is tilted towards the Sun.
Explain how it is warmer in the summer if Earth is farther away from the Sun.
