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. Sputtering: 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.

It’s made for your children to work as independently as you want them to. Here is curriculum I have written based on what’s available for free and linked to this site. These are for elementary age through high school, K-12. If you find problems with the links don’t just assume the site doesn’t exist anymore.

Home | Practical Physics. This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory.

We have published a new set of resources to support the teaching of practical science for Key Stages 3-5. 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 heart of the program is a fast-paced presentation of physics demonstrations carefully chosen to be entertaining as well as educational.

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 » Course Structure This Yale College course, taught on campus twice per week for 75 minutes, was recorded for Open Yale Courses in Fall 2006.

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. One of the best physics resources available. 2. 3. 4. 5. 6. 7. 8.
