Night and day are like two different worlds. In this activity for the very youngest children, we introduce the concept of the spinning Earth and the use of a sundial.

This lesson is an introduction to the reading of NIGHT by Elie Wiesel, which students will read independently. The students will do research to discover the different colors and symbols used to symbolize the Nazi party's list of undesirable people. The students will gain an understanding of how other people can arbitrarily judge other people as inferior.

This activity helps children understand that the Earth is round and the origin of day and night. Image planets and space, and draw or paint it.

Use an UNAWE Earthball to facilitate in understanding day and night.

This is what the Earth looks like at night. Can you find your favorite country or city? Surprisingly, city lights make this task quite possible. Human-made lights highlight particularly developed or populated areas of the Earths surface, including the seaboards of Europe, the eastern United States, and Japan. Many large cities are located near rivers or oceans so that they can exchange goods cheaply by boat. Particularly dark areas include the central parts of South America, Africa, Asia, and Australia. The above image is actually a composite of hundreds of pictures made by the Defense Meteorological Satellite Program (DMSP) currently operates four satellites carrying the Operational Linescan System (OLS) in low-altitude polar orbits. Three of these satellites record nighttime data. The DMSP-OLS has a unique capability to detect low levels of visible-near infrared (VNIR) radiance at night. With the OLS VIS band data it is possible to detect clouds illuminated by moonlight, plus lights from cities, towns, industrial sites, gas flares, and ephemeral events such as fires and lightning-illuminated clouds. The Nighttime Lights of the World data set is compiled from the October 1994 - March 1995 DMSP nighttime data collected when moonlight was low. Using the OLS thermal infrared band, areas containing clouds were removed and the remaining area used in the time series. This animation is derived from an image created by Craig Mayhew and Robert Simmon from data provided by Christopher Elvidge of the NOAA National Geophysical Data Center.

Packet of activities to assist in explaining solar and lunar eclipses, night and day, the four seasons and much more.

"This course explores how our views of Jewish history have been formed and how this history can explain the survival of the Jews as an ethnic/religious group into the present day. Special attention is given to the partial and fragmentary nature of our information about the past, and the difficulties inherent in decoding statements about the past that were written with a religious agenda in mind. It also considers complex events in Jewish history -- from early history as portrayed in the Bible to recent history, including the Holocaust."

When the Earth spins around on its axis, it creates night and day on Earth. This movement makes it look like the Sun is moving across the sky. The Sun rises in the east and sets in the west, turning day into night.

This interactive feature from the NOVA "Leopards of the Night" Web site highlights the nighttime habits and abilities of a wide range of nocturnal creatures.
