AM I on the Radio?
During this activity, students create a working radio by soldering circuit components supplied from an AM radio kit. Since this activity is carried out in conjunction with the associated lessons concerning circuits and how an AM radio works, students should be able to identify each circuit component they are soldering, as well as how their placement causes the radio to work. Besides reinforcing concepts from the lessons, this activity will also teach students how to solder. Soldering is an activ
Design a Parachute
After a discussion about what a parachute is and how it works, students will create a parachute using different materials that they think will work best. The students will test their designs, which will be followed by a class discussion (and possible journal writing) to highlight which paper material worked best.
Testing the Caverns
This lesson provides a fun, activity-based closure to the Asteroid Impact unit. Students build model caverns using paper mache or clay and bury them in a tray of sand. Next, they test the models by dropping balls onto them to simulate an asteroid hitting the earth. By molding paper mache around a balloon to form a dome, or around a small cardboard box to form a rectangular structure, students will be able to build their caverns.
In this unit, students learn about the six simple machines and are introduced to compound machines. In the first lesson, students learn about work as defined by physical science and see that work is made easier through the use of simple machines. The second lesson introduces students to three of the six simple machines used by many engineers: the inclined plane, the wedge and the screw. Also, students become familiar with each machine's mechanical advantage and how it makes work easier. The thir
New Boxes From Old
Students find the volume and surface area of a rectangular box (e.g., a cereal box), and then figure out how to convert that box into a new, cubical box having the same volume as the original. As they construct the new, cube-shaped box from the original box material, students discover that the cubical box has less surface area than the original, and thus, a cube is a more efficient way to package things.
Introduction a la méthode des éléments finis en mécanique des solides
Polycopié d'un cours numérisé de l'INSA de Lyon. Le but de ce polycopié est de donner les principes de base de la méthode des éléments finis en élasticité. C'est une méthode de calcul qui consiste à découper en "éléments" la structure à étudier. Ces éléments sont définis par des noeuds dont le rôle sera largement précisé et dont la réunion doit représenter aussi fidèlement que possible la pièce a calculer. Cette façon d'opérer est satisfaisante pour prendre en compte
4.2.5 Scanners and OCRs
How does the computer's peculiar binary world of digital entities differ from our analogue world of colour, sound, taste and touch? This unit explores the way in which information, in the form of text, still and moving images, and sound can cross the boundary from the analogue universe into a digital world.
Load It Up!
Students take a hands-on look at the design of bridge piers (columns). First they brainstorm types of loads that might affect a Colorado bridge. Then they determine the maximum possible load for that scenario, and calculate the cross-sectional area of a column designed to support that load. Choosing from clay, foam or marshmallows, they create model columns and test their calculations.
As Charlotte uses her web to communicate, the students will also create a web to send a small message. The students will learn how a spider creates its web, and about the different types of webs spiders make. With this knowledge, the students will design and create their own web and incorporate a message.
Sound Booth Construction
Students explore the sound dampening ability of numerous materials by designing and prototyping model sound booths. As a result, students learn about how sound is reflected, absorbed and travels through various materials, thus giving them an overview of sound dampening, energy absorption and sound propagation in the context of engineering. Students also create blueprints and document their findings in a formal lab report.

Leon Sverdlove On the Taft-Hartley Act
The Taft-Hartley Act, passed in 1947, symbolized the anti-labor climate of postwar America. The act expanded the power of employers and the government to prevent union organizing and strikes, and made it difficult for unions to take industrial action. The most difficult aspect of the bill for many unions to swallow required labor leaders to declare themselves to be non-Communist if they wanted to participate in NLRB elections. While many union members, like Leon Sverdlove of the Jewelry Workers
This activity is designed to allow students to observe termite trail-following behavior. Termites will tend to follow lines made on paper by ballpoint pens because the ink contains a chemical that is similar to the trail pheromones used by termites to lead colony members to food sources. There are several pen brands that termites will follow and a great many other products (including markers, pencils etc) that they will ignore.
