Primary Science. DIY Electron Accelerator: A Cathode Ray Tube in a Wine Bottle. As complex as the idea of a particle accelerator might seem, it's actually strikingly simple to implement.
The design we will be using was first created in the late 19th century by J.J. Thomson and subsequently used to make several important discoveries about the fundamental nature of the atom and the electron. Later, in the early 20th century, Cockroft and Walton (yup, the same hooligans responsible for the voltage multiplier) used a similar design to build the first true electrostatic linear accelerator, or "static linac" for short. Nowadays, advanced versions of this type of accelerator are commonly used for radiotherapy and ion implantation.
Essentially, our cathode ray tube is just two electrodes in a vacuum chamber with a high voltage applied between them. Some interesting effects that can be observed at this stage are sputtering and magnetic deflection. Free Curriculum - PreK - 8. The Easy Peasy All in One Homeschool – I’m working on a complete, online, free curriculum.
It is for Pre K through high school. It is everything: reading, language arts, writing, art, music, science, history, math, computer, health/PE, Bible and logic. It has everything laid out. You can do it by course–like just use it for science–or, you can use it for everything. It’s laid out so that your child can go to day 4 and just go down all the assignments for that day. Download & Streaming : Open Educational Resources : Internet Archive. MIT OpenCourseWare (OCW), available at , makes the course materials used in the teaching of all MIT undergraduate and graduate subjects available on the Web, free of charge, to any user in the world.
Educators utilize the materials for curriculum development, while students and self-learners around the globe use them for self-study or supplementary use. With more than 2,000 courses now available, OCW is delivering on the promise of open sharing of knowledge. This library of open educational resources features course materials for seven Advanced Placement (AP) courses. Practical Physics. The Wonders of Physics. In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see.
A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds. --Albert Einstein Never has there been a time when an understanding of science has been more important to the well-being of individuals and to the nation than the present. Yet many recent studies have documented a lack of interest in science and hence a decline in science literacy in the United States. To address this problem, the University of Wisconsin - Madison in 1984 began a program called The Wonders of Physics aimed at generating interest in physics among people of all ages and backgrounds. The show has been presented by Professor Clint Sprott on the Madison campus over 250 times to a total audience of about 90,000. Fundamentals of Physics I. About the Course This course provides a thorough introduction to the principles and methods of physics for students who have good preparation in physics and mathematics.
Emphasis is placed on problem solving and quantitative reasoning. This course covers Newtonian mechanics, special relativity, gravitation, thermodynamics, and waves. View class sessions » Great Physics Resources for Students and Teachers. I teach Physics and AP Physics B and have found some great resources over the years to use in class and to share with students as support materials.
Here's a list of some of them. 1. The Physics Classroom - this site is excellent. It has a tutorial section (online lessons with links, practice problems and simulations) along with a review section, help for solving word problems, links, multimedia resources and much more. The lessons are in easy to understand terms and each subject area is broken down into small parts. Physics.org. Light and Matter: open-source physics textbooks. David Tong: Teaching.

Module C : Motion and Forces : Physics Flash Animations. We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations.
LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below.
