A guide to calculating absolute and percentage error, experimental error, propagating errors and using excel to construct appropriate graphs treating errors via error bars, best, steepest, shallowest gradients etc.

Full guide to laboratory reports for IB Includes error treatments.

Rate of change of momentum investigated through the medium of lego. And hard boiled eggs. For goodness sake, make sure they are HARD boiled. Use of ICT in lessons. I did this as a video lesson and the camera man was getting all wobbly at using his flashiest kit. Works just as well with an iPhone (my footage was shot on iPhone) the better stuff made by the kids (not uploaded here because the files are huge), was on a Go pro hero 4- in high speed mode- other action cameras are available. What is the difference between Physics and Titting about? Accurate measurements. Try it.,

A test written for pre-IB pupils, can be edited, includes data handling and longer response questions.

Additional Notes and reflections from having run this lesson now through a complete cycle. Quite honestly I plan to put this into a bundle with other large video files, but I'm struggling with the upload of the slow-mo videos.

A cover lesson activity that reinforces the relationship between C and K and then leads onto E=mc deltaT Includes key skills activity of plotting a graph.

This is a good Pre-IB pupil's lab report that I use as a marking exercise for staff and pupils as preparation for their IB DP work. There are lots of examples out there of pupils' lab reports from primary data- but this one was conducted from secondary source data. A good activity to give to pupils with marking criteria to check they understand the rubric for a lab report.

This is for pupils to develop the ability to use a spreadsheet (I wrote it in excel) to process a large amount of data in order to calculate a value for g (set to be a little lower than 9.8) and then lead into consideration of experimental errors. Using s=ut + 1/2at2 pupils can calculate gravitational acceleration. Pupils are provided with values for s and t Pupils need to calculate a mean t from a very large data set (easy to do using excel). Pupils then need to square the mean t. Then they need to plot s against t2 which will give them a linear graph with the gradient as 1/2 a. The worksheet is editable so weaker pupils can have more guided instructions. Stronger pupils can work their way through. The accompanying worksheet then looks at errors in measurement- absolute and % AND there is a random error in the data set. Pupils can use absolute errors in the data to determine size of error bars, Pupils can work out experimental error, plot best, steepest and shallowest trend lines for g and compare that against the total % error in their data.

A simple 1 hour test comprising of multiple choice, longer responses, data handling (graph plotting and calculations) and reading and comprehension activities. It is editable so you can change it for your needs. Progressively more challenging, from simple responses, to short answers, to open questions. I have included a short reading and comprehension section to support my EFL candidates.
