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.
Photosynthesis – Life’s Primary Energy Source
This lesson covers the process of photosynthesis and the related plant cell functions of transpiration and cellular respiration. Students will learn how engineers can use the natural process of photosynthesis as an exemplary model of a complex — yet efficient — process for converting solar energy to chemical energy or distributing water throughout a system.
Students explore the many different ways that engineers provide natural lighting to interior spaces. They analyze various methods of daylighting by constructing model houses from foam core board and simulating the sun with a desk lamp. Teams design a daylighting system for their model houses based on their observations and calculations of the optimal use of available sunlight to their structure.
Engineering: Simple Machines
Simple machines are devices with few or no moving parts that make work easier. Students are introduced to the six types of simple machines — the wedge, wheel and axle, lever, inclined plane, screw, and pulley — in the context of the construction of a pyramid, gaining high-level insights into tools that have been used since ancient times and are still in use today. In two hands-on activities, students begin their own pyramid design by performing materials calculations, and evaluating and sele
The Growling Stomach
In this lesson, the students will investigate what types of plants and insects they could eat to survive in the Amazon. They will research various plants and/or insects and identify characteristics that make them edible or useful for the trip. The students will create posters and present their findings to the class.
U.S. says Gaddafi weakened but not defeated
U.S. military officials say Gaddafi is not close to a military breaking point even though coalition strikes have seriously degraded his fighting power. Deborah Lutterbeck reports.
Eureka! Episode 10 - Potential Energy vs Kinetic Energy
A rock teetering on the edge of a cliff is shown to have potential energy - the energy of position. Eureka was a series of short cartoons on physics that ran on public television in the 1980's. The video explains the concept in simple and well illustrated way. Good for students of any elementary school level. (04:51)
