Students explore the concepts of center of mass and static equilibrium by seeing how non-symmetrical objects balance. Using a paper cut-out shape of a parrot sitting on a wire coat hanger, they learn that their parrot exists in stable equilibrium it returns to its balancing point after being disturbed. The weight of its tail makes the parrot balance upright. Give the parrot a push, and she knocks off balance, but swings back and forth until coming to rest in balance again.
The flash animations present the characteristics of wind power as a source of clean energy and allows the viewer to examine how a modern wind turbine works by pausing and clicking on its components.
Energy -- Elastic and Inelastic Collisions in Two Dimensions for Blind Students
This module explains elastic and inelastic collisions in two dimensions in a format that is accessible to blind students.
Build a LabVIEW subVI to sample a signal on demand and hold the signal value across multiple calls to the subVI.
Video Player Flash kit
This hands-on activity explores the concept of static electricity. Students attract an O-shaped piece of cereal to a charged comb and watch the cereal jump away when it touches the comb. Students also observe Styrofoam pellets pulling towards a charged comb, then leaping back to the table.
How World War One Ended
This 2:48 long video explains the steps that lead to the defeat of Germany. The video also explains what happened in Russia and France. The video uses original footage.
"The Engineer of 2020, Fall 2009"
" Numerous recent studies have shown that the U.S. has relatively low percentages of students who enter science and engineering and a high drop-out rate. Some other countries are producing many more scientists and engineers per capita than the U.S. What does this mean for the future of the U.S. and the global economy? In this readings and discussion-based seminar you will meet weekly with the Dean of Undergraduate Education to explore the kind of education MIT and other institutions are and shou
Maternal/Placental Hormones Supporting Fetal Growth and Development
An interactive animation depicting how maternal/placental hormones, including estradiol, cortisol, and progesterone, support fetal development (i.e., lung maturity, length, weight) and placental weight. Guide questions - What is the relationship between fetal growth and placental growth during gestation? What is the relationship between fetal length and fetal weight during gestation? What is the relationship between fetal lung maturation and gestational age? What are the functions of chorionic g
Please Excuse My Dear Aunt Sally: Math Mnemonic Device
This three minute video to help students determine order of operations when solving an equation. It uses music instead of narration.
Students observe the relationship between the angle of a catapult (a force measurement) and the flight of a cotton ball. They learn how Newton's second law of motion works by seeing directly that F = ma. When they pull the metal "arm" back further, thus applying a greater force to the cotton ball, it causes the cotton ball to travel faster and farther. Students also learn that objects of greater mass require more force to result in the same distance traveled by a lighter object.
Computer Science Unplugged
Tim Bell is an Associate Professor in the department of Computer Science and Software Engineering at the University of Canterbury in Christchurch, New Zealand. His current research interests include Computers and Music, Public Understanding of (Computer) Science, and educational applications of podcasting. Credits: Speaker:Tim Bell (50:20)
Support Walls Being Poured for Barret Library.
Wood and metal supports for pouring concrete for "basement" walls.
In this lesson, students are introduced to communications engineers as people who enable long-range communication. In the lesson demonstration, students discuss the tendency of sound to diminish with distance and model this phenomenon using a slinky. Finally, Alexander Graham Bell is introduced as the inventor of the telephone and a pioneer in communications engineering.

Photonic Dipole Contours of Ferrofluid Hele-Shaw Cell (Two Magnet Pole Video)
This investigation describes and demonstrates a novel technique for the visualization of magnetic fields. Two ferrofluid Hele-Shaw cells have been constructed to facilitate the imaging of magnetic field lines. We deduce that magnetically induced photonic band gap arrays similar to electrostatic liquid crystal operation are responsible for the photographed images and seek to mathematically prove the images are of exact dipole nature. This is the two magnet version with the poles mostly facing the
What is consciousness? How does the brain generate consciousness and how can a science of the mind describe and explain it adequately? This unit will introduce you to the slippery phenomenon that is consciousness, as well as some of the difficulties consciousness presents to science and philosophy.
How does what you say come to mean something? Does what you say inherently represent what you, the speaker, think it means, whatever that might be, or does what you say carry its own meaning, separate from your intentions in saying it? This unit introduces you to the key questions about how meaning is conveyed in language.
