a fun video about bar magnets

I made a fun video about dipoles in molecules.

I made a crazy video about hydrolysing water with a hofmann voltameter Note: the youtube version is free. I only put a price on the download because you have to do that for the resource to appear on TES pages.

As the title. Based on AQA GCSE specification.

I made a simple worksheet about density. 5 pages. Two of info, one table of values, a page of questions and my answers. I have now added a keynote and powerpoint version.

I made a tiny gcse question about radioactivity.

I made a wacky little video about this.

I used colour to enhance this simple display. Might be of use to someone.

I took the AQA Physics keywords document and used those words to make a word search for each topic. Eight word searches in total.

Made for my own satisfaction I have now added a set of bingo cards as an alternative

A Drag & Drop exercise for building up the electronic structure of atoms. After a short cartoon for building up an atom of calcium, students build up four atoms by drag and drop. Could be used projected on the whiteboard or by students individually at computers. Double click on the full atomic structure.html file and it will open in your browser. I made it big for projection, but it can be made smaller by zooming out using the browser zoom control. A preview is available on my web site Please note: in order to provide a rich interactive experience, my drag & drop resources are mini-web sites local to your computer. After unzipping, they comprise a folder containing the main .html file and another folder containing the graphic resources and my coding to make the resource work. Double click on the .html file and the resource will work. If, however , you move or delete any of the files from this hierarchy, the resource will not work.

There are erroneous diagrams on this web site for this diagram. I aim to correct this . Keynote, powerpoint and pdf formats.

Distance/time and velocity/time labelling excercise. With answer sheet which could be used as a handout for notes.

Preparing for a lesson with a student on waves, I was searching for diagrams to illustrate it. The internet is awash with suitable diagrams, but they all seem to be low-resolution bitmaps. Being a vector graphic fanatic, I made some high quality graphics of my own. I offer them in pdf, keynote and powerpoint formats.

A simple simulation of the experiment. Unzip the file. Open the folder. Double click on ‘spring stretch version 4.html’ and it opens in your browser. Add the masses by clicking the buttons, and watch the spring stretch. Use a ruler to measure the extension. (The anomaly on the graph at 3N is probably due to a draught of warm air expanding the spring as a door was opened). Enjoy! A preview is availableon my web site.

I made a wacky interactive widget thingy to illustrate the gas laws. Change the property with the slider and it draws the graph. Just for fun really. A preview may be seen on my web site.

This is better than my old one.

Just three diagrams for students to label. I have left the teacher to specify which labels are required. I hope it is of use to somebody , somewhere.

A simple labelling exercise.
