Pi = 3.14159...
What is Pi? Who first used Pi? How do you find it? How many digits is it?
Drift Seeds And Drift Fruits : Seeds That Ride The Ocean Currents
This essay explores seed dispersal by water and describes some of the physical adaptations that evolution has produced in the seeds and fruits that travel this way. There is a background essay, discussion questions, state and national standards, and links to related Teacher's Domain resources.
Part of the larger Imagine the Universe educational site, the Electromagnetic Spectrum site is another great resource from NASA. The site gives clear and easy-to-understand explanations, while providing keywords throughout the page that are linked to a dictionary of terms for easy access to further information. Students will enjoy the colorful illustrations accompanying the text, which vertically follow the spectrum from radio to gamma rays, while teachers will appreciate the related lesson plan
Data Analysis and Measurement: Ahead, Above the Clouds
This is the Educator Guide of an archived NASA (National Aeronautics and Space Administration) CONNECT program designed to help students discover that in predicting severe weather and tracking clouds, NASA engineers and scientists are developing technologies to collect data that will help them better understand Earth's climate. The guide includes an activity in which students play a game that will help them understand the complexity of hurricane forecasting. They will be given the coordinates fo
Cold Clouds and Water in Space
This article from Astrobiology Magazine reports on the discovery of water in cold regions of space. Using data from the European Space Agencys Infrared Space Observatory, astronomers have determined that water is abundant in these cold, or quiescent regions of space where there are no stars, and that the majority of it occurs as ice with a small amount of water vapor. It is thought that these cold regions of space might be the future birthplaces of low-mass stars like our own sun. Links to other
Science Sampler : Thriving in the co-taught classroom
Classrooms are becoming more diverse as students with specific learning needs are moved out of self-contained special education classrooms and into mainstreamed classrooms with their non-disabled peers. The use of the co-teaching model allows for extensive flexibility in structuring instructional activities and responding to the needs of diverse learners. This article provides a summary of co-teaching practices that have been effective and beneficial for many years.
Examine evidence of Earth turning about an axis
Using an animation of the classic pendulum experiment, this resource supplies middle and high school students with evidence of the Earth's rotation on its axis. The introduction explains that although pendulums are known to swing in a fixed path, on Earth their path appears to shift over time. As the animation reveals, it is not the pendulum's swing that changes--it is the Earth beneath the pendulum that moves. The animation contains three screens: two with different views of a pendulum swinging
Observe some products of a Geographic Information System (GIS)
By combining a short paragraph and six enlargeable maps, this resource explains to students what a Geographic Information System (GIS) is. Introductory text explains that GIS technology enables users to plot multiple data sets onto maps of varying scales. Then six sample maps produced through GIS are provided. Among these maps is one that identifies where energy and mineral resources are located globally and another that highlights and labels the rivers that drain into the Mississippi River. Cop
Observe an animation of the Coriolis effect over Earth's surface
This pair of Earth science animations uses airline flight patterns to demonstrate the Coriolis effect in the Northern and Southern Hemispheres. The animations first show two planes' target destinations and intended flight paths on a stationary Earth. Then, the planet rotates, revealing that the plotted routes would take the plane in the Northern Hemisphere to the right of its intended destination and the plane in the Southern Hemisphere to the left of its intended destination.

Everest : Test Your Brain
This interactive feature from the NOVA Everest Web site lets you take the same brain quizzes that researchers used to test the brain function of climbers on Mount Everest.
The Electromagnetic Spectrum: FRONTLINE
This video segment adapted from FRONTLINE introduces the electromagnetic spectrum and explains how the various types of electromagnetic waves are distinguished by the amount of energy each wave carries.
The Homestead Act of 1862
The Homestead Act of 1862 - Imagine that you can’t feed your family, or maybe you risk persecution for your political or religious beliefs. But, suddenly, you hear the call: Come along to make a new life in a wide-open land. In a few years, you’ll own that land, for yourself and your descendents, free, and forever. This offer turned out to be a cornerstone in the very foundation of America’s heartland.(03:31)
Wemberly Worried by Kevin Henkes Read A Loud
In this video, students will meet a mouse named Wemberly. She worries too much. She has a list of worries. Wemberly worries about everything especially about her first day of nursery school. She meets a new friend Jewel at school. This is a good companion teaching resource for reading Kevin Henkes books in the classroom. It helps to bring literary characters to life. Content is appropriate for elementary students. (2:46)
Multiple Sclerosis - Station and Gait Exam - Station Sub-exam - Patient 20
Janie is a 39-year-old Caucasian female who initially presented with weakness and L'Hermitte’s phenomena at the age of 35. Initially mistaken as a TIA, MRI of the brain revealed numerous plaques in the white matter suggesting Multiple Sclerosis. Her lumbar puncture initially failed to demonstrate the presence of oligoclonal bands, but since progression of the disease over the past few years bands have developed.
2.14 Summing up
This unit is concerned with macroevolution – the patterns and processes of evolution above the species level. A crucial consideration in macroevolutionary studies is that of the evolutionary relationships (phylogeny) of the organisms in question. The unit begins with an introduction to the scope of macroevolutionary studies and illustrates methods of reconstructing phylogeny, from both morphological and molecular data.
Appendix 1 Terminology
Optical-fibre communications became commercially viable in the 1970s and innovation continues today. This unit will illustrate how very high data rates can be transmitted over long distances through optical fibres. You will learn how these fibres are linked, examine the technology used and assess the future direction of this continually developing area of communication.
Engineering and the Human Body
The Engineering and the Human Body unit covers the broad spectrum of topics that make-up our very amazing human body. Students are introduced to the space environment and learn the major differences between the environment on Earth and that of outer space. The engineering challenges that arise because of these discrepancies are also discussed. Then, students dive into the different components that make up the human body: muscles, bones and joints, the digestive and circulatory systems, the nervo
3 Politics: Radicalism and reaction
Childcare, education, working conditions, healthcare, crime … these issues are hotly debated in today's society. They are also issues that Robert Owen, seen by some as a visionary and by others as a knave and a charlatan, sought to address in the early 1800s. This unit uses a series of essays written by Owen to explore the ideas of this important and controversial figure.
Which Roof is Tops?
When you walk or drive around your neighborhood what do the roofs look like? What if you lived in an area with a different climate, how would that effect the style of roof that you might find. This is an introductory activity to explore the advantages of different roof shapes for different climates or situations.
