Time-Warp Archive of Vintage Technology Through the Decades
The time-warp project is dedicated to preserving information about the advancement of technology. It currently focuses on specific innovations of the 20th century. The site lets users travel decade by decade through illustrated living rooms typical of the period. Technology is grouped into several categories, such as televisions, calculating machines, radio, photography, and telephones. For a given selection, examples of the technology representative of the decade are shown. These include specif
A collaboration between three universities is working to create a battery that is capable of powering microelectromechanical systems (MEMS). The work is especially important because no viable battery currently exists for these tiny devices. The three-dimensional battery will be a departure from current battery designs, which stack "positive and negative electrodes... like sheets of paper." As more electrodes are stacked to make a higher capacity battery, the size and weight increases dramaticall
IOL: InterOperability Lab
The University of New Hampshire has compiled this excellent collection of resources on networking and computer technology. Over twenty categories are represented, including emerging technologies such as 10 Gigabit Ethernet, Very high rate Digital Subscriber Line (VDSL), and wireless standards. Many of the resources are papers or tutorials written by researchers at the UNH InterOperability Lab, while others are links to various academic and industry efforts. The site is suitable for a broad audie
Geometry is the branch of mathematics which investigates the relations, properties, and measurement of solids, surfaces, lines, and angles. It is the science of the relations of space. Sourse: Webster's Dictionary
Students design, build and test model race cars made from simple materials (lifesaver-shaped candies, plastic drinking straws, Popsicle sticks, index cards, tape) as a way to explore independent, dependent and control variables. They measure the changes in distance travelled with the addition of mass to the vehicles. Students also practice the steps of the engineering design process by brainstorming, planning, building, testing, and improving their “mint-mobiles.”
This lesson will allow students to explore an important role of environmental engineers: cleaning the environment. Students will learn details about the Exxon Valdez oil spill, which was one of the most publicized and studied environmental tragedies in history. In the accompanying activity, they will try many “engineered” strategies to clean up their own manufactured oil spill and learn the difficulties of dealing with oil released into our waters.
Does Weight Matter?
Using the same method for measuring friction that was used in the previous lesson (Discovering Friction), students design and conduct an experiment to determine if weight added incrementally to an object affects the amount of friction encountered when it slides across a flat surface. After graphing the data from their experiments, students can calculate the coefficients of friction between the object and the surface it moved upon, for both static and kinetic friction.
Swing in Time
Students examine the motion of pendulums and come to understand that the longer the string of the pendulum, the fewer the number of swings in a given time interval. They see that changing the weight on the pendulum does not have an effect on the period. They also observe that changing the angle of release of the pendulum has negligible effect upon the period.
Two Sides of One Force
Students learn more about magnetism, and how magnetism and electricity are related in electromagnets. They learn the fundamentals about how simple electric motors and electromagnets work. Students also learn about hybrid gasoline-electric cars and their advantages over conventional gasoline-only-powered cars.
The Need for Shelter
In this lesson, the students will build a shelter in order to protect themselves from the rain. After the shelters are built, the class will perform durability and water proof testing on the shelters.
Oceans, climate and weather
What is the difference between weather and climate? What do the oceans have to do with them? Weather is the day-to-day state of the atmosphere and its short-term (minutes to weeks) variation. Climate is typically described by the regional patterns of seasonal temperature and precipitation over 30 years. The averages of annual temperature, rainfall, cloud cover, and depth of frost penetration are all typical climate-related statistics. The oceans influence the worlds climate by storing solar ener
What is Energy?
With an introduction to the ideas of energy, students discuss specific types of energy and the practical sources of energy. Hands-on activities help them identify types of energy in their surroundings and enhance their understanding of energy.
Taking the Boat to Manaus
In this activity, the students will apply the concepts they learned regarding mass, volume and density in the previous activities to design a boat.
Pi Day : Making a Pi Necklace
Diana Funke teaches mathematics at Davisville Middle School in North Kingstown, RI. Her students make a Pi necklace for Pi Day to reinforce the idea that some numbers never repeat or end. They assign a color to each digit (including 0) and then string beads of those colors into a necklace, using the digits of Pi as their guide.
Edd Presnell: Dulcimer Maker
Edd Presnell, a mountain craftsman and native of Watauga County, North Carolina, demonstrates and comments on the construction of a dulcimer. Presnell learned his craft from his father-in-law. Film includes a brief performance on a finished dulcimer by his wife, Nettie. This 16mm film is archived in the Thomas G. Burton and Jack Schrader collection in the Archives of Appalachia, East Tennesse State University.

Titan Beetle--An Overview
This short video gives excellent real life, close up footage of a Titan Beetle. Probably the largest insect in the world, the adult titan beetle,Titanus giganteus, cuts an imposing figure. The adult beetle has a flattened body, long, soft wing cases covering a large abdomen, and long spiny legs. The mouthparts, or mandibles, are narrow, powerful, and distinctly longer than the head. This is a great resource to help build background knowledge and to help make real world connections
Otis: Share a Memory of the Woman's Building: Kathleen Forrest
Otis College: Doin' It In Public: Feminism and Art at the Woman's Building: Weekend of October 15-16, 2011: Still Doin' It: Fanning the Flames of the Woman's Building: Share a Memory of the Woman's Building During the Weekend of October 15-16, 2011, women gave their memories of their experiences at the Woman's Building. Some were there and participated in numerous activities, some were influenced by it. Otis College exhibition "Doin' It In Public: Feminism and Art at the Woman's Building"
Normal - Station and Gait Exam - Station Sub-exam - Patient 1
Patient is a female with no known neurological health problems who volunteered to act as a simulated patient in order to demonstrate 'normal' responses to exam techniques. She is merely a reference point for exam procedures and protocols, as well as to denote subtle signs from diagnosed patients.
