To download the files below for Datalogging Insight software (from Logotron) click on the items marked with the Insight icon. These are "ISA" files that Datalogging Insight recognises. Go to the program's file menu to open them. Thanks are due to Laurence Rogers, author of Datalogging Insight software for adding his results. 

Look for this icon below if you use other software. If you right click this: Photosynthesis: oxygen levels in an aquarium a menu will appear.  Choose "Save target as" or "Save link as". A dialogue will appear to choose where to save it. Start Excel, open "files of type all files" and treat the file as comma separated data. Otherwise open your data logging program and look for the option to open or import 'SID files'.

Many thanks to Data Harvest (www.data-harvest.co.uk) for these experiment files. They will load straight into Data Harvest's EasySense software, though most other data logging software and Microsoft Excel will be able to use them.

If you use other software do follow these instructions. If you just click a file this will produce a page of numbers. That's no good to you, so instead right click the icons where the pointer turns into a hand, and a menu will appear. Choose "Save link as" or "Save target as". A 'save' dialogue should appear, click OK to load the file to your computer. Open your data logging program and search the File menu for the option to open or import 'SID files'. 

A SID file is a CSV text file where the experiment results table is separated using commas instead of lines. You can, import such files into most UK data logging software. Microsoft Excel can handle it too, but data logging software is almost essential for daily work.

Candle burns in a bell jar and the oxygen level changes. That proof enough?

Steve Allen's party trick is to drop a magnet through a coil, then ask what happens if he turns the magnet round and drops it the other way round. You need really fast logging for this one. 

But look what happens if you just dangle a magnet from a twisted rubber band right next to a coil 

The current surge when a bulb lights. See also the screen dump where I have adjusted the y axis. Results by Sue Plant at Data Harvest.

Heat - using a heat loss sensor based on the worksheet produced by Roy Barton of University of East Anglia. Plot the difference between Temperature 1 and Temperature 2 against heat flow - it forms a straight line. Featured in Data Harvest Summer '99 Newsletter which should be on the website.

A waveform from our new sound sensor recording at 28,000 readings per second. The file is middle C of a piano. Use an Interval tool to find the time period from peak to peak = 3.885ms. Dividing 1 second by .003885 gives the result of 259.7, rounded up to 260 which I believe is the frequency of middle 'C'. Not bad for a bit of homework. The sound sensor normally gives a decibel reading, but when switched to mv can be used for really fast logging. Not as fast as an oscilloscope but it gets results.

and Two acid-base titration results files, the first is done by adding acid and using 'snapshot' to take a reading at each point. The file shows points as each 2 ml of alkali was added by pipette - we used 0.1M sodium hydroxide and 0.1M hydrochloric acid. This is from our new KS3 worksheets. The second file, titre.sid is the traditional alkali drained from a burette into acid.

Food as a fuel - burn vegetable oil and compare different oils. It needs zooming to see it properly. By Reshma Syed 

A file to show what happens in a collision between two hard surfaces measuring force. We repeated the collision with the same mass and at the same speed where one surface is 'cushioned'. The area under the graph in each case is the same. We kept repeating the collision with the hard surface - the force sensor gives such consistent readings.

Thanks to Barbara Higginbotham of Data Harvest for these.
