Tacoma Narrows Bridge: Lessons From the Failure of a Great Machine. How Galloping Gertie collapsed left us a lasting design legacy.

Tacoma Narrows Bridge: Lessons From the Failure of a Great Machine

The Damage Main cables: During the collapse, the main suspension cables were thrown violently side to side, twisted, and tossed 100 feet into the air. They slipped from their positions in the cable saddles atop each tower. And, they fell hard on the approach spans. On the north cable at mid-span, where the cable band loosened, it broke more than 350 wires. Suspender cables: The violent collapse broke many suspender cables. Towers: The main towers (West Tower, #4; and East Tower, #5), including the bracing struts, were twisted and bent.

A Hand-Cranked Automaton That Mimics the Effect of a Raindrop Hitting Water. This little wood automaton is meant to mimic the effect of a water drop hitting a body of water, all using concentric rings cut from wood that are manipulated by a hand crank.

The piece was created by UK-based designer Dean O’Callaghan, inspired by the work of Reuben Margolin (most likely his round wave sculpture). A mesmerizing pendulum wave demonstration with 16 bowling balls in a North Carolina forest. If you’ve ever been to a science museum or taken a physics class, you’ve probably encountered an example of a pendulum wave.

This video shows a large-scale pendulum wave contraption built on private property in the mountains of North Carolina, near Burnsville. Elementary STEM Activity 2 - Designing and Constructing a Pendulum.pdf. ISTS homepage. NPASS2: National Partnerships for After School Science. The game of pinball is a relatively recent invention.

NPASS2: National Partnerships for After School Science

Some say it was developed from a billiard-like game called bagatelle. Some of the earliest versions resembled Pachinko machines, which were upright boards with many pins through which a ball was dropped to earn points. This may be the origin of the word "pinball. " Today's arcade and video pinball games are much more complex than the ones of yesteryear, however they are similar in that a ball is rolled onto a board with bumpers (pins) and traps (holes), scoring points depending on what the ball hits and where it lands on the game surface.

Nineteen thirty-one saw the introduction of coin-operated machines, such as Ballyhoo. In 1947, flippers were first introduced into the game. Pinball games are still popular with children and adults. This project has an additional benefit for children. Wallace and Gromit - World of Invention. STRANDBEEST.

Arvind Gupta. Our core belief is that children learn by doing - by touching, feeling, cutting, sticking -- pulling things apart, putting things together.

We believe that this hands-on science helps them relate to curriculum and get conceptual understanding. We believe this will revolutionize the way children learn. A child lighting up a LED with a Syringe Generator is more likely to light up his village tomorrow. Our approach is inclusive. All the materials used in our activities are very affordable and accessible to every child across the globe, developing or developed countries alike. Ours is the most cost effective outreach program in the world, with cost of 15 paisa per person (0.2 cents per person). Our Goal We want to design science and math activities to comprehensively cover the whole curriculum. Understanding Movement & Making Automata.

The game can be accessed by a wide range of individuals with differing special needs and for mainstream participants as well. The ball is held at the length of the attached line from the stand and released slightly pushed. Galimoto! Self-Made Toys on Pinterest. Galimoto Boy. Found materials + engineering process = toy. We didn’t have enough wire so we re-used cardboard tubes, empty boxes, egg cartons, and plastic jar lids to create toys called “Galimotos” in the Malawian children’s tradition as recounted in the children’s book, Galimoto by Karen Lynn Williams and illustrated by Catherine Stock.

Found materials + engineering process = toy

Galimoto means “car” in Chichewa, the national language of Malawi and many, but not all, of our creations were vehicles. The small group of kindergarten and first grade girls drew their designs and then built their own toy to take home in a one hour library sponsored program. A third grade lesson plan (with additional links) from LEARN NC from the University of North Carolina at Chapel Hill describes this activity as an “opportunity to engage in creative self-expression by designing and creating wire sculptures.” Psyclone Pendulum Thrill Ride.

Thanks to a reader, I have been introduced to Wild Gears. They have turned my spirographic art world upside down! Fermi's Motion Produces a Study in Spirograph. Mad Scientist: Pendulums, Patterns from Sand. The Mad Scientist In this experiment, we will be examining the pendulum.

Mad Scientist: Pendulums, Patterns from Sand

We will learn what a pendulum is, learn some words that will help us describe pendulums, and use a pendulum to draw patterns that are made out of sand. Materials: Activity Guide: Pendulum Motion. Swinging back and forth, the solo trapeze is a giant pendulum just like the one in a grandfather clock. The time it takes to swing forward, then back to where it started is called the period. Surprisingly, this time has very little to do with the height of the swing, or amplitude. It depends mainly on the length of the pendulum, the longer the pendulum, the longer the period. The Science of Swinging. Swing in Time. Amusement Park Physics. You've bought your ticket and boarded the roller coaster. Now you're barreling down the track at 60 miles per hour, taking hairpin turns and completing death-defying loops.

Your heart is in your throat and your stomach is somewhere near your shoes. The only thing separating you from total disaster is a safety harness...but are you really in danger? The designers of the roller coaster carefully crafted this thrilling ride to be just that, but you're actually in less danger than you think. You face a greater threat of injury playing sports or riding a bike than you do on a park ride. How do physics laws affect amusement park ride design? Cabaret Mechanical Theatre. Www.robives.com. Milk Carton Marble Run. Humming.Bird. Mechanical Toy Set. A comprehensive set of traditional mechanisms for young children. The 10 wooden toys are based on traditional designs of toys that incorporate mechanisms, all of which are used today in all kinds of machines. The accompanying book provides questions for use in product evaluation activities and support materials designed to help children understand that drawings can communicate a variety of ideas and information.

Contains: bobbing Boats cars milk bottles pecking chicks roundabout snowmen twirling penguins Teachers Book - explains to the teacher the way in which the toys may be used with both KS1 and KS2 classes to explore and develop new design skills, and encourages the teacher to allow children to progress onto the making stage.
