Observe how air pressure affects a rising balloon
This animation enables students in high school Earth science classes to observe how atmospheric pressure changes with respect to altitude. Students are instructed to click and drag a lever to move a balloon between altitudes of 5,000 and 30,000 feet. A pair of gauges indicates the volume in the balloon and the atmospheric pressure at each elevation. The legend indicates that the concentration of air molecules decreases with increasing altitude.

Science Sampler : Thinking about students' questions
Asking questions is a vital component in any classroom, but it is absolutely essential in a science classroom. As science teachers, we know that questioning plays a major role in the inquiry process and has a positive impact on students' learning. This article discusses the importance of questioning skills and current research on questioning techniques. In addition, this article will present a series of lessons that were implemented by the author to improve the questioning abilities of middle sc
The modern atom model
All particles in the atom are in constant motion, according to modern atomic theory. On this page of a tutorial on particle physics, students evaluate the relative size of atomic particles. If protons and neutrons are balls with a 1-centimeter diameter, then electrons have the diameter of a hair. The comparable size of an atom made from these particles would be 30 football fields long. Students read that atoms are mostly empty space. Copyright 2005 Eisenhower National Clearinghouse
Miss Lindquist: The Tutor
A free Web tutoring system for middle school and high school students concentrating on writing expressions for algebra word problems. Teachers can assign portions of this site for homework, students can get help as they do their homework, and progress reports can be sent to a teacher's e-mail address. The program randomly selects problems from the section that the student is working on, e.g.: One-operator problems; harder one-operator probems involving speed, distance, and time; easier two-opera
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.
An Introduction to the Coordinate Plane
This math site has students find points on a number line and graph points in the coordinate plane. Site includes information about negative numbers on a line, changing the scale of a graph, estimating points, and tricky graphs. A glossary of terms, links to other sites, and suggestions on how to use the material can also be found.
Etymologies of Algebra, Geometry, Trigonometry
What are the origins and roots of the words geometry, algebra, and trigonometry?
The Ocean Project
The Ocean Project is a collaboration of several zoos, aquariums, science museums, and conservation museums/organizations who are committed to providing better education to their respective visitors and the public regarding the importance of the oceans and the role each person plays in conserving the earths waters. The website offers access to public opinion research, communication strategies, conservation networks, and information and research to informal educators, in order to promote the ocean
Cups and Volume
How can I calculate the volume of a box, if I know how many cups of rice fill it? And how can 2 cups be a volume measure?
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 an animation of cave formation
Created for high school students, this resource presents an animation of how caves develop. A short paragraph introduces the animation, and text boxes in the animation supply further information. The movie begins with the acid in groundwater dissolving limestone and ends with the appearance of stalactites and stalagmites in caves. Movie controls allow students to pause, replay, or move backward or forward through the animation. Copyright 2005 Eisenhower National Clearinghouse
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.
Introducción al Sistema Jurídico Internacional y de la Unión Europea (2010)
La asignatura pretende ofrecer al alumno que por primera vez se enfrenta al mundo del derecho una aproximación al Derecho Internacional Público contemporáneo así como a la Unión Europea y su Ordenamiento jurídico. Se trata de dos manifestaciones jurídicas muy distintas a las que los alumnos del Título de Grado van a estudiar en las distintas ramas del Derecho interno español, pero que al mismo tiempo tienen en este un grado de penetración cada vez más importante. La asignatura está p

LUNCH IS GROSS!
Countdown to MIX11: Get Your Science On When the content team plans sessions for MIX not only do they take into account practicality and applicability, but
they also are tasked with programming inspirational content. And a lot of that mind-blowing, peek into the future content comes from the big brains working at and partnering with Microsoft Research. Charles Torre joins us this week to talk about the R&D presence at MIX this year, including both sessions and
