Curiosity Cabinet Over the past 25 years I have accumulated a collection of various gizmos, devices, toys etc. which to me are excellent examples of scientific principles or things that you look at and you say "That's impossible!" except it's staring you in the face. In the hope that others may also find them interesting and with the help of two undergraduates, Jacy Lundberg and Omar Khan, we have created videos of many of the items in the collection. In many cases we have tried to include explanations of how they work or references to where one can find this information. Jacy and Omar are currently seniors in the Boston College pre-medical program. Omar is from Portland, Oregon and Jacy is from Los Angeles, California. In the olden days some people assembled what were known as curiosity cabinets.

PhysicsLAB: Converging Lenses Any lens that is "thicker in the center" than on the edges is generally described as a convex lens and will function as a converging lens when it is operating in air. The point where all rays which enter the lens parallel to its axis are brought to a focus is called the principal focus. This position is located behind the lens and is usually labeled as F in ray diagrams. A similar point the same distance in front of the lens is called the lens' secondary focus, F'. The distance from the center of the lens to the principal focus is called the focal length of the lens and is represented by the variable, f. Whenever the actual rays of light that refract through the lens converge behind the lens to form an image, that type of image is called a real image. Since the actual rays of light passing through the lens form these real images, they are also known as "hot" images. Converging Lenses There are three primary rays which are used to locate the images formed by converging lenses.
Welcome to a Resource for Physics Teachers | Physics & Physical Science Demos, Labs, & Projects for High School Teachers This site is designed to help physics teachers share their ideas. Many of us are the sole physics teacher in their school. It’s nice to know there are others out there to help develop experiments and demonstrations. I will be listing many of my demos and activities along with a commentary on what works and what doesn’t. The school I teach in is new. 2006/2007 was the first year there was a 12th grade. I’m looking for contributors, even if it’s one or two postings. – Scott Like this: Like Loading... prettygoodphysics - home
You'll Flip Over Forces & Motion Submitted by Heidi BaitzLudlow Elementary SchoolLudlow, Vermont 05149baitzh@ludlowelementary.org Digital Wish Grant Does Your Classroom Flip? “We are Newtonians, fervent and devout, when we speak of forces and masses, of action and reaction; when we say that a sports team has momentum, when we note the inertia of a tradition or bureaucracy; and when we stretch out an arm and feel the force of gravity all around, pulling earthward.” James Gleick Overview:This intensive course, designed specifically for K-8 teachers, will focus on forces and motion as understood through Newton’s Laws of Motion. Goal:This past summer while co-teaching a course on “Forces and Motion” at Castleton State College, my partner, Dr. Lesson:During the week-long course, students were exposed to a variety of inquiry-based learning and hands-on activities. As a culminating activity of this course, students were put into groups of four and sent on a scavenger hunt using their flip cameras. Forces & Motion Scavenger Hunt
HyperPhysics Concepts About HyperPhysics Rationale for Development HyperPhysics is an exploration environment for concepts in physics which employs concept maps and other linking strategies to facilitate smooth navigation. For the most part, it is laid out in small segments or "cards", true to its original development in HyperCard. The entire environment is interconnected with thousands of links, reminiscent of a neural network. The bottom bar of each card contains links to major concept maps for divisions of physics, plus a "go back" feature to allow you to retrace the path of an exploration. Part of the intent for this exploration environment is to provide many opportunities for numerical exploration in the form of active formuli and standard problems implemented in Javascript. New content for HyperPhysics will be posted as it is developed. A resource that was initiated as a resource for local high school physics teachers whom I had taught has expanded into an intensively used website worldwide. HyperPhysics

Now, one man may have the answer to ensure the Slinky fun never stops. Matthias Wandel is a Canadian woodworker who regularly uploads videos to YouTube of him creating innovative toys and devices like marble machines or a "Jenga Pistol" out of wood. Wandel recently tackled the challenge of creating a "Slinky escalator," a device that when operated correctly could keep the toy in motion without it coming a stop. In the video, Wandel crafts the machine from scratch, making adjustments along the way to help keep the Slinky from toppling over. The video has already earned nearly 400,000 views since being uploaded last week. "It's these novel but useless contraptions that get people interested," Wandel wrote on his website.
Roller Coaster - Museum of Science and Industry Learn about energy as you send a marble through a roller coaster that you design. Materials Marbles or small balls About 6 feet of flexible tubing, such as ¾-inch foam pipe insulation Masking tape Plastic cup Scissors Various supports, such as boxes, paper towel tubes or books Directions Cut the tubing in half. This doubles the amount of “track” for the roller coaster.Your “car” (the marble) needs kinetic energy at the beginning of the roller coaster so that it can make it through the entire course. What's happening? A roller coaster demonstrates kinetic energy and potential energy. Extensions Once you get your roller coaster to work, try starting the coaster at a higher point and see what happens. Find the velocity of the marble. Vocabulary Kinetic energyEnergy from motion Potential energyStored energy that transforms into kinetic energy
