  What are SID data files?
 
 
 
 
Results from data logging experiments

Here you can download data saved from experiments and use it in Excel or your data logging program. There are a few gems to illustrate key science ideas. We used them in our training days. Their associated experiments are in the galleries (left) and in the book 'Data logging in Practice'.

  • to download all the SID data files on this site in one zip file, click here: files.zip. Import a file with your data logging program*. Or import one with Excel by treating them as CSV text files. They could be tidier.

  • to see screenshots of the data scroll down or click Gallery: graphs


*To download the files below for Datalogging Insight software click on the items marked with the Insight icon. These are "ISA" files that 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 say: Photosynthesis: oxygen levels in an aquarium a menu will appear.  Choose "Save target as" or "Save link as" and 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'. 

The instructions are crucial because your PC doesn't know what to do with a file. The SID file is a CSV text file where the results are separated using commas. You can, import such files into most UK data logging software and Microsoft Excel.

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. 

Remember - Right click to Save the file to disk:

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

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. Results by Sue Plant at Data Harvest.

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.
