DCI: ESS1.B (A) Earth and the Solar System – The orbits of Earth
around the sun and of the moon around earth, together with the rotation of
Earth about an axis between its North and South poles, cause observable
patterns. These include day and night; daily changes in the length and
direction of shadows.
PE: 5-ESS1-2 Represent data in graphical displays to reveal
patterns of daily changes in length and direction of shadows, day and night,
and the seasonal appearance of some stars in the night sky.
[Clarification
Statement: Examples of patterns could include the position and motion of Earth
with respect to the sun and selected stars that are visible only in particular
months.] [Assessment Boundary: Assessment does not include causes of seasons.]
The ideas we see in this standard are:
-The earth orbits around the sun
- the moon orbits around the sun
- the earth rotates on its axis
- all of these movements cause observable patterns (day/night, day length, direction of shadows)
The PE is definitely geared more towards classroom activities, rather than assessment. It will be difficult to have students create their own graphical displays about the patterns causes by the movements of the Earth. However, we can provide graphical displays and have them describe what kind of movement is causing the change. Because the standard makes mention of the patterns, we can also have them do predictions on what will happen next.
Possible Question Starters:
"Students are modeling the Earth, the Sun, and their relative motions. A basketball is used to represent the Sun, and a tennis ball is used to represent Earth. In order to accurately model the cause of day and night on Earth - the students must -
correct answer - rotate the tennis ball on its axis.
incorrect answer - rotate the basketball on its axis.
"Saturn rotates on its axis once approximately every 10.5 hours. From this information, it can be concluded that Saturn will differ from Earth in which of the following ways
correct answer - shorter day
incorrect answer - more extreme temperatures
correct answer - rotate the tennis ball on its axis.
incorrect answer - rotate the basketball on its axis.
"Saturn rotates on its axis once approximately every 10.5 hours. From this information, it can be concluded that Saturn will differ from Earth in which of the following ways
correct answer - shorter day
incorrect answer - more extreme temperatures
