Teachers TV: Most popular Persuasive writing (ages 7-11) Five short video clips provide a stimulus for pupils to employ a range of persuasive writing techniques. Primary maths - Measures Children have to estimate the volume of puddles, make muffins and concoct magic potions. Science - Forces (ages 5-11) Four primary teachers present their great lesson ideas for teaching forces and motion in science. English - Writing activities Three teachers share great lesson ideas to boost pupils' writing skills - plus resources you need to use these ideas. Maths - Shape and space Teachers at two schools use fun games to engage their pupils in maths lessons about shapes and space.
Detexify LaTeX handwritten symbol recognition Want a Mac app? Lucky you. The Mac app is finally stable enough. See how it works on Vimeo. Download the latest version here. Restriction: In addition to the LaTeX command the unlicensed version will copy a reminder to purchase a license to the clipboard when you select a symbol. You can purchase a license here: Buy Detexify for Mac If you need help contact mail@danielkirs.ch. What is this? Anyone who works with LaTeX knows how time-consuming it can be to find a symbol in symbols-a4.pdf that you just can't memorize. How do I use it? Just draw the symbol you are looking for into the square area above and look what happens! My symbol isn't found! The symbol may not be trained enough or it is not yet in the list of supported symbols. I like this. You could spare some time training Detexify. The backend server is running on Digital Ocean (referral link) so you can also reduce my hosting costs by using that referral link. Why should I donate? Hosting of detexify costs some money. No. Yes.
Gapminder: Unveiling the beauty of statistics for a fact based world view. TeacherTube - Teach the World Physics Flashlets Michael Fowler See also our Applets! This is a collection of Flash animations to make learning physics easier! They were created by myself and my students Jacquie Hui Wan Ching and Heather Welch, and Michael Timmins and , in the summer of 2003. Some of these flashlets are not quite perfect yet, but we’re working on it. Pythagoras: prove Pythagoras’ Theorem fast by moving triangles around with your mouse. Eclipse of the Moon: a short movie of the Moon moving through the Earth’s shadow, and how it appears from Earth. Ptolemy's Epicycles for Inner Planet Motion: actually a simplified version, with just the basic epicycle idea illustrated. Ptolemy's Epicycles for the Outer Planets: again, just the basic epicycle idea. Earth-Mars Line of Sight in Two Models. Kepler’s Laws: construct your own planetary orbits and check Kepler’s Laws! The Inner Planets: a movie of the inner planets in orbit ... and here are the Outer Planets. Trip to Mars! Carnot Cycle: the Carnot engine in action! Chinese Version
OER Commons 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. 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. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
Physics and Flash Flash is well-known for producing spiffy animations. Not as well-known is how to use it for demonstrations in the sciences using proper mathematical equations to control the motions. Using proper Physics equations for animations is also useful for realistic games. We will create 5 different animations below. When this document was written, the current Flash program was MX 2004. The Undamped Harmonic Oscillator We will use a harmonic oscillator, such as a mass oscillating on a spring, as our example. A is the maximum amplitude of the oscillation. (pronounced omega naught) is the "natural" angular frequency of oscillation, and depends on the mass and the particular spring. t is the time. (pronounced phi) is called the "phase angle" of the oscillation, and essentially depends on what moment in time we choose to call zero. In this document we will be clever and choose the phase angle to be zero. Faking It Our undamped oscillator will have a period of 2.0 seconds. This is not good. Problem 1 Here
