day and night spinner

© K. Wright 2012
Assembly Suggestions:
1. See the photo on page 3 for proper assembly.
2. It is recommended that the spinner and background page be printed in color on
cardstock weight paper. If a color printer is not available, it is recommended that you
highlight the sun yellow and points A, B and C in a bright color such as pink or green.
3. Attach a fastener in the center of the Earth and the center of the day and night circle.
The lines on the Earth should come very close, if not exactly line up with the dots
around the edge of the day and night circle. Some imperfection will occur due to printers
and copy machines. When giving directions to students, emphasize that they should
read the spinner from the closest dot!
Remind students that this activity simulates Earth’s rotation causing day and night. Explain
that it does not necessarily show the correct time for the locations, as the spinner does not
account for the Earth’s tilt and the changes in the amount of daylight and darkness as Earth
orbits the sun.

Copy the background
on cardstock paper.
Highlight if color ink
is not available.
Copy the Earth
spinner, cut and
mount with a
pivoting fastener.
Copy the student
questions and post
near each spinner.
Example of how to read the spinner:
Point A is just past midnight at approximately 1 am. Point C is at 4 am. Point B is at approximately noon. I
have this in Active Inspire flipchart format as well. It allows to you spin the Earth on the board to model the
process. If you are a Promethean user, send me a message on TpT and I will email you the flipchart!

Earth’s Rotation Lesson Plan
Essential Question: How does Earth’s rotation cause day/night, time zones, sunrise and
sunset?
Materials:
Spinners made from Earth printable, day and night printable and a fastener (12-15 per class)
Student question sheets (12-15 per class)
Globe (1)
Flashlight (1)
Internet access for sharing satellite image website
Build Background:
Model the process of day and night using a flashlight and a globe. Turn all of the classroom lights off and model
how light from the flashlight (sun) can only reach ½ of the globe at any given time. Put a large sticker on your
school’s town on the globe and spin the globe slowly modeling sunrise, day, noon, sunset, and night. Emphasize
the following main ideas:
 Rotation: To move in a circle around a central point or axis
 Earth rotates from West to East. This is why we see the sun set in the West and rise in
the East. The further East a location, the sooner they experience the next day!
 At all times, 1/2 of Earth is lit by the sun; the other 1/2 is in darkness.
 The Earth’s axis is tilted 23.5 degrees from vertical. The day and night line does not
line up with the tilt, causing some regions of Earth to have very long periods of daylight
or darkness at some points throughout the year.
 Make sure you share this amazing website that has a real time updated image of the day
and night line! http://www.fourmilab.ch/cgi-bin/uncgi/Earth/action?opt=-p
 The Brainpop website also has a pretty decent video on time zones that addresses the
main idea of this activity. If your school is not a subscriber, you can sign up for a free
two-week trial!
Spinner Activity:
Once students have a handle on the main concepts listed above, organize students into small groups of 2-3 to
work on using the spinners to simulate the Earth’s rotation, day and night and time zones. Explain and model
how the spinner works and remind them to make sure they spin it counter-clockwise! Allow time for students to
answer the questions while you circulate to support any struggling students.
Once all students have completed the task, go over the answers and questions as a class to ensure understanding.
