Quick take on stream ecology
Planning your spring units? Most kids (and their teachers) love to get into the field to do science. The activities provided here can stand alone or act as a complement to activities done with the assistance of department of natural resources personnel.
What do computer programmers actually do? This is the introductory page for a set of materials about computer programming as a career. Here the job of a computer programmer is defined and described. Computer programmers write and maintain computer software. In the rest of the resource, students can examine a specialized job title associated with computer programming: software developer. Students can view a six-minute video clip of the software developer as he works on writing software and debugg
Maths: Number : Short and long division
Worked examples of short and long division problems. For long division, an applet gives a step-by-step demonstration of the procedure; the pace at which the learner views each step is controlled by the user.
Observe solar eclipses
This Earth science animation helps students compare three types of solar eclipses: total, partial, and annular. The introduction explains how the type of eclipse is determined by variations in distance and alignment between the Earth, sun, and moon. The animation follows the events of all three eclipses concurrently. Movie controls allow students to repeat, pause, or step through the animation, which can give students more time to compare the eclipse sequences. Copyright 2005 Eisenhower National
Water reclamation plant (RealVideo)
In this video clip, students see how wastewater is treated at a water reclamation plant. One of the plant's operators gives Bob the Vid Tec (a children's programming host) a tour of the plant, describing along the way what happens at each step in the water treatment process. For example, the operator explains that microorganisms are used to consume human waste in the biological nutrient removal step. Bob also talks with another plant operator about why kids should learn about wastewater treatmen
About 2000 years ago the Greek astronomer Hipparchus discovered that the position of the Sun at any season, measured against the background stars, migrates in a slow cycle of about 26000 years. This precession of the equinoxes also shifts the position of the celestial pole (so that our pole star would not have been a good guide for the ancient Greeks) and is caused by the rotation axis of the Earth slowly moving around a cone. Precession may be one of several astronomical processes contributing
Warning Signs for Dangerous Times : Exploring the Use of Storm-Tracking Technologies
In this lesson, students explore the use of storm-tracking technologies, research how natural disasters are predicted, and assess the importance of these technologies. A case study of a New England snow storm and its impacts is presented for discussion, along with suggestions for retrieving information about forecasts as well as links to weather prediction and warning sites.
What are agricultural scientists, and what do they actually do? This is the introductory page for a set of materials about agricultural science as a career. Here the job of an agricultural scientist is defined and described. In the rest of the resource, students can examine two specialized job titles associated with agricultural scientists: organic specialist/assistant professor and senior research associate. Students can read narratives that are a few paragraphs in length about an organic speci
What is a method of active solar energy production? This article, part of a series about the future of energy, describes the use of large reflector power plants in the Mohave Desert. Students are introduced to the use of large solar reflectors to heat molten salt and produce energy for homes. Students view four photographs of different aspects of the solar complex.

Problems with a Point
A collection of problems designed to help students in grades 6-12 learn new mathematical ideas by building on old ones. Varying in difficulty and approaches, these problems are useful for teachers, students, parents, math clubs, home-schoolers, and others. Problems are classified by topic, time required, suggested technology, required mathematical background, and habits of mind that students develop or use as they work. Synopses of the problems are keyword searchable. Answers and solutions are p
The Yo-Yo Problem
Students will explore linear patterns, write a pattern in symbolic form, and solve linear equations using algebra tiles, symbolic manipulation, and the graphing calculator. This lesson plan includes the objective, overview of the lesson, needed materials, procedures, assessment, extensions and adaptations, tips, resources, ideas for discussion, and the activity sheets and answer key.
Space blocks : algebra (grades 6-8)
This virtual manipulative offers the student an opportunity to develop spatial sense and the ability to model ideas using mathematics. In seven activities, the student models shapes with cubes and observes patterns related to surface area of a solid. Activities involve forming largest and smallest solids using eight blocks and determining which of three networks of squares decorated with colors and shapes can be folded to form a given cube. This manipulative provides two user controls. The stude
Mystery Mud : Exploring Changes in States of Matter
Join a group of middle-school students on a visit to a laboratory at the Massachusetts Institute of Technology, where they experiment with mystery mud and learn about the relationships between magnetism, particle motion, and changes in the state of matter.
Introduction to Bacteria
This science site has students research how bacteria move, where they live, and how they reproduce; learn how bacteria can be helpful or harmful; and create a design illustrating what they have learned about bacteria. Included in the lesson plan are the objectives, needed materials and Web sites, procedures, discussion questions, evaluation, extensions, suggested reading, and vocabulary. Teachers can link to Teaching Tools to create custom worksheets, puzzles, and quizzes. A printable version of
Physical science is the science of matter and energy and their interactions and examines the physical world around us. Using the methods of the physical sciences, students learn about the composition, structure, properties, and reactions of matter and the relationships between matter and energy. Students are best able to build understanding of the physical sciences through hands-on exploration of the physical world.
Earth and Space
In earth and space science, students study the origin, structure, and physical phenomena of the earth and the universe. Earth and space science studies include concepts in geology, meteorology, oceanography, and astronomy.

What Is Renaissance Art?
The Renaissance period of art was full of great innovations as artists expanded their technical skills of making super-realistic images both in paint and in sculpture. This 2:23 long video explains the origins of the Renaissance art with information from an art historian, critic and curator. Unfortunately, there are no photos of the art as it is a talking head video.
