How ozone is made
How does ozone in the upper atmosphere help protect life on Earth? This informational piece, part of an interactive laboratory series for grades 8-12, explores the production and destruction of ozone in the upper atmosphere. Here students view an animation of ultraviolet light breaking an oxygen molecule to form ozone and then the ozone splitting when struck by ultraviolet light. Text explanations are provided along with chemical equations. Copyright 2005 Eisenhower National Clearinghouse

This site has students learn the basics of coordinate graphing and practice plotting points on the coordinate axis. Site includes the introduction, prior knowledge, appropriate grade levels, objective, resources, procedures, learning advice, evaluation, extensions, and conclusion. An introduction to the coordinate plane and coordinates, a coordinate game, maze game, graphing quiz and answer key, coordinate grid, and additional Web links can be found.
The Quest for the Perfect Weather Forecaster
Just how accurate are weather forecasters, anyway? How can a meteorologist from one television channel predict a completely different forecast for the same area on a different station? To answer these queries, this article describes two projects for middle level students to investigate these issues in a hands-on, active-learning environment. These three-week projects take the form of webquests?inquiry-oriented exercises focusing on analysis, synthesis, and evaluation, for which the Internet is t
Celestial navigation is the process of finding your position on Earth based on astronomical guideposts. In this lesson, explore the principles of navigation; build tools to observe celestial bodies, and learn how science, mathematics, technology, and history are intertwined.
Statistics and probability. Grades 6-8
This MathPARTNERS unit contains seven lessons with hands-on learning activities for exploring statistics and probability with students in grades 6-8. The lessons, designed for mentoring situations, may also be helpful for teachers and parents. Each lesson with reproducible student materials, features an overview of the mathematics, preparation guidelines, teaching tips, and suggestions for how to use each activity to develop specific mathematics concepts. Statistics activities focus on posing qu
Geoboard : circular (grades 6-8)
This virtual manipulative enables the student to form and measure angles and triangles on an online circular geoboard. The unusual virtual geoboard offers students the opportunity to think about angles in a non-rectangular setting. This applet features five activities with discussion questions. Activities challenge students to form and use the pegs to determine the degrees of central angles and angles found in triangles. Instructions for using the applet, an outline for a lesson encouraging the
Learn to Build a Rocket in 5 Days or Your Money Back
In this lesson, students discover the entire process that goes into designing a rocket for any customer. In prior lessons, students learned how rockets work, but now they learn what real-world decisions engineers have to make when designing and building a rocket. They learn about important factors such as supplies, ethics, deadlines and budgets. Also, students learn about the Engineering process, and recognize that the first design is almost never the final design. Re-Engineering is a critical s
An eighteen minute video that is a lecture about these artists with photos. As with most art videos, preview it first should there be an image that may not be appropriate for your class. A good video that provides great insights into the movement, artists, and style of painting.
Designing a Winning Guest Village in the Saguaro National Park
The Challenge Question of the Legacy Cycle draws the student into considering the engineering ingenuity of nature. It will force him to analyze, appreciate and understand the wisdom of these designs as the student team focuses on meeting each of the challenge’s requirements. The student is asked, with his team members, to envision a sustainable design for a future guest village within the Saguaro National Park, outside of Tucson, Arizona. What issues need to be addressed to support the comfort
Heat Transfer: From Hot to Not
Students learn the fundamental concepts of heat transfer and heat of reaction. This includes concepts such as physical chemistry, an equation for heat transfer, and a basic understanding of energy and heat transfer.
Mixtures and Solutions
This unit covers introductory concepts of mixtures and solutions. Students think about how mixtures and solutions, and atoms and molecules can influence new technologies developed by engineers. The first lesson explores the fundamentals of atoms and their structure. The building blocks of matter (protons, electrons, neutrons) are covered in detail. The next lesson examines the properties of elements and the periodic table — one method of organization for the elements. The concepts of physical
Students complete a series of six short investigations involving magnets to learn more about their properties. Students also discuss engineering uses for magnets and brainstorm examples of magnets in use in their everyday lives.
For Those Back Home…
Students review information learned during the past five lessons and activities of the Introduction to Engineering unit. Working in teams, they create flyers and short quizzes about various types of engineering to share with the class and collect into a "Olympic Engineering Binder" for the class to keep.
Students are introduced to our Sun as they explore its composition, what is happening inside it, its relationship to our planet (our energy source), and the ways engineers help us learn about it.
Our Big Blue Marble
Students are introduced to the fabulous planet on which they live. Even though we spend our entire lives on Earth, we still do not always understand how it fits into the rest of the solar system. Students learn about the Earth’s position in the solar system and what makes it unique. They learn how engineers study human interactions with the Earth and design technologies and systems to monitor, use and care for our planet’s resources wisely to preserve life on Earth.
Cutting Through Soil
Students pretend they are agricultural engineers during the colonial period and design a miniature plow that will cut through a “field” of soil. Students are introduced to the engineering design process and learn of several famous historical figures who contributed to the design of the plow.
