Evidence of Rotation and Revolution
Written by Adi Ackerman, Head Teacher
"Evidence of Rotation and Revolution" is written for 7th Grade (Ages 12-13), and it covers NGSS MS-ESS1-1. A 6th grader who is already steady on Earth and space can use it too, and an older student can use it as a short review.

FAQ
How do I use this seasons worksheet?
⌄
Use Evidence of Rotation and Revolution first to separate daily and yearly motion. Then use the Sun angle sheet to explain the seasons with numbers.
What does this worksheet teach?
⌄
Use star trails and shadow lengths of a 100 cm pole as evidence for Earth's rotation and revolution. The directions on the page read: Read the text. Then answer question 1 by filling in the table. An answer key is included.
Can I use this seasons worksheet for homeschool or classroom?
⌄
Yes, both. We made it for 7th grade Earth and space, and it works the same at home or at school. At home, a student can work through it alone and then go over it with you, which shows quickly what is solid and what needs another look. In class it works as independent practice, homework or a warm-up, and you can print one copy or a full set.
What causes day and night?
⌄
Earth rotates once on its axis about every 24 hours, which makes the Sun and stars seem to cross the sky.
Why is a shadow shortest at noon?
⌄
The Sun is highest in the sky at local noon, which is not always 12:00 on a clock. The shadow sheet shows a 100 cm pole's shadow falling to 84 cm and rising again.
Why are summers warmer?
⌄
In summer the noon Sun is higher, so sunlight spreads over a smaller area. The beam diagrams on the Sun angle sheet show this.
