A short, light-hearted drama for Y10 students. It covers Jenner's vaccination experiments. I had a group that did not seem to 'get' acquired immunity so I thought this might be a way of presenting it to them. It takes about 5 minutes to perform and you need another 5 - 10 choosing a cast and sorting out some space. It makes quite a good plenary

This spreadsheet will generate a random name from the class list. Download and save the spreadsheet. Open it (you must enable editing and macros) and replace the names with your class members. Make sure each one has a corresponding number in the first column, then click on the 'Go' button. This was put together as a bit of fun for my Y9 science classes.

Starter for Probability topic. 'Coins in Bag' type puzzle that can be set using the first 3 slides. The remaining slides show the answer with working. Shows how to multiply across to calculate probability for 2 step events. Demonstrates that sometimes maths will come up with counterintuitive answers. All images are creative commons. Updated 23.12.12 due to issue with later version of Office not working on older software.

Originally done for Y10 A combined cloze and wordsearch. Useful for mixed ability groups, get them all to have a go at the cloze, those who finish can do the wordsearch while the others catch up.

A brief PowerPoint on Avogadro's number, what is a mole and making molar solutions. All images are Creative Comons. Ends with an extension piece on the molarity of water.

Students create a poster or cartoon strip illustrating a skydive. I generally give them each a sheet of A3 paper to do this. There is a cutoff bit of graph paper on the task sheet which they can use to sketch the velocity time graph. This can be stuck onto their poster.

Students are given expressions with brackets that need to be expanded. When they have done each expansion they can cross it off their card if it is present. The first student(s) to complete their card wins. This activity is suitable for students who have a good understanding of how brackets are expanded and need a bit of practice or revision. There is also a PowerPoint; Algebingo.ppt that will display the questions if you do not want to write them on the board.

A pre-built 9 x 9 table for Sudoku puzzles. These may be done as a class activity, particularly useful for small groups of high-ability students. These is a pre-populated simple slice&dice puzzle on page 2. I use these as a fun activity with a small tutorial group of high functioning ASD boys.

Student handout is not really necessary but I wanted them to get to the data/graphing bit without too much writing as at the time our lessons were only 40 minutes.Good exercise in graph plotting; data collecting and recording.

How Walter and Luis Alvarez examined evidence of iridium in the KT boundary and came up with the idea of a massive meteorite impact at Chixculub which caused the mass extinction of the dinosaurs. This is presented as part of the Queensland curriculum. The intenton is to illustrate how scientists gather evidence, consult with experts in their own and other fields, research previously published work in books, journals and on the web. They then publish their hypotheses for peer review as well as discussing and evaluating explanations which differ from their own.
