CHEMISTRY HOME EXPERIMENT : Make Things Glow In The Dark Have you ever wondered what makes certain things glow under black lights? For this experiment you will need: • a black light• petroleum jelly• a piece of paper First we’ll use the petroleum jelly as a kind of invisible ink. A Philosophical Toy by Richard Frazier For nearly a decade I have challenged my students (grades 7-9) to answer the question, "How did the Cartesian Diver get its name?" The students who have taken up this challenge have returned with little more than a description of the device and a conviction that the name is eponymous, that "Cartesian" is derived from the name of the French mathematician and philosopher Rene Descartes (1596-1650). Never has a student found a documented link between the diver and Descartes although some science activity books suggest Descartes was the inventor (Vilenkin in Kikoin, 1980). We have recently made a more concerted effort to pursue the question and have posted queries by electronic and regular mail to science educators, to researchers at science museums, and to historians and philosophers of science.

5 Fun Science Experiments for Kids Everyone knows science is awesome, but did you know you can do science right in your own kitchen? Ok, maybe you did, but if you're not sure where to start, we've got five really fun experiments that demonstrate the scientific principles of buoyancy, surface tension, density, chemical reaction and non-Newtonian fluid. Best of all, families can do these easy experiments with common, household items. Sesame Street's fuzzy, blue scientist Grover stopped by the #5facts studio to teach us a few things about the scientific method. Watch the adorable video above to see the experiments in action, then use the instructions below to gather everything you need for your home science lab. Looking for more amazing experiments families can do together?

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. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary.

Make a Bouncing Polymer Ball - Experiment with Polymers Introduction Balls have been toys practically forever, but the bouncing ball is a more recent innovation. Bouncing balls were originally made of natural rubber, though now bouncing balls can be made of plastics and other polymers or even treated leather. You can use chemistry to make your own bouncing ball. Once you understand the basic technique, you can alter the recipe for the ball to see how the chemical composition affects the bounciness of the ball, as well as other characteristics. The bouncing ball in this activity is made from a polymer.

5 Best Rock Songs for Learning English Listening to music in a foreign language is a great way to learn vocabulary – just find the words online and use a dictionary for anything you don’t know. Or just have songs playing while you do your homework. I’ve tried to choose songs which are easy to understand and can be found on Youtube or Spotify, but which are still brilliant music! 5. Paramore – crushcrushcrush When you have a 'crush' on someone, you really REALLY like them, and this song describes this perfectly. vintage belt frame I’m sure you’ve seen plenty of wayward western belts at vintage shops and thrift stores.
