This is the imaginary line that the Earth rotates on.
What is an axis?
This means Earths spins on its axis.
What is rotation?
This phase is in when the moon is in between the Earth and the Sun.
What is the new moon?
The Earth’s orbit and the Earth’s tilt causes these on Earth.
What are seasons?
This is when the Earth goes around the sun.
What is orbit or revolution?
The model shows Earth during part of its orbit around the Sun.
This causes half of the Earth to experience daylight at a time.
What is the rotation on its axis?
This helps show why the amount of daylight changes throughout the year.
What is the tilt of the Earth?
This is when more shadow is shown than lumination on a moon.
What is cresent?
This is when more lumination is shown than shadow on a moon.
What is gibbous?
This adjective means when sunrays point straight down.
What is direct?
This adjective means when sunrays point diagonal down.
What is indirect?
The model below shows the Earth in one of its positions as it moves around the Sun.
The Southern Hemisphere is experiencing this season.
What is summer?
The model below shows the Earth in one of its positions as it moves around the Sun.
The Northern Hemisphere experiencing winter would have these kind of days and these kind of nights.
What is shorter days and longer nights?
This is when the luminated part of the moon is shrinking?
What is waning?
This means when the luminated part of the moon is growing.
What is waxing?
Students are given the following image to try to figure out which season is represented in the images and provide evidence for their explanation.
A is summer because it has these kinds of rays.
What are direct rays from the sun?
Students are given the following image to try to figure out which season is represented in the images and provide evidence for their explanation.
D is winter because it has these kinds of rays.
What are indirect rays from the sun?
The following chart shows the average length of daytime from sunrise to sunset for six months of the year in Atlanta, Georgia.
If making a model of this chart, this month would be when the Earth would be directly tilted toward the sun.
What is June?
The following chart shows the average length of daytime from sunrise to sunset for six months of the year in Atlanta, Georgia.
If making a model of this chart, this month would be when the Earth would be directly tilted away from the sun.
What is December?
A student wants to design a model to show different phases of the moon.
This is one improvement a student could make to this model.
What is adding the sun?
A student created the following chart to show the phases of the moon.
This is an improvement a student can make to this model.
What is putting the phases in a circle?
A student wonders why it is colder in the winter than in the summer. Winter has less daylight hours and less of these kind of rays.
What are less direct rays?
A student wonders why it is warmer in the summer than in the winter. Summer has less night time and more of these kind of rays.
What are more direct rays?
A student is creating a model of the Earth and the Sun to explain why the length of day and night change throughout the year. This would be the most important thing to include in the model.
What is the tilt of the Earth?
The model below shows the earth on the summer solstice for the Northern Hemisphere.
This year of the Earth would not receive any daylight.
What is the Antarctic Circle?
A student creates the following model to show phases of the Moon on the North Pole.
This letter would be what an observer would see from the North Pole.
What is A?
A student created a model about the phases of the moon.
This is why the circles are only half luminated.
What is light only hit half of the moon at a time?
Noah made the following model to explain why Georgia receives a shorter amount of daylight in the winter compared to the summer
This is one strength of Noah's argument.
What is making Earth tilted?
Noah made the following model to explain why Georgia receives a shorter amount of daylight in the winter compared to the summer.
This is one correct you could make to Noah's argument.
What is changing the explanation to "Georgia is on the part of the earth that is tilted away from the sun, so it will not receive as much daylight."
