About Me
 Mr. Barnett’s Site
Downloads
These are potentially useful science downloads. I  make no promises about anything on them, but they have been useful to some people.
Formulas download
My structured program for revising formulas.  Save it to disk on your system and run it from there, or run it straight from this link.  You will need about 80 minutes to do the whole sequence, but you can start at four different points if you need to stop and return later.
Pondweed download
My simple program for simulating the pondweed experiment.  Save it to disk on your system and run it from there, as it needs to unzip itself.
Random calorimetry download
An Excel spreadsheet for creating random calorimetry problems for GCSE and A-level.  Save it to disk on your system and run it from there, by right-clicking and choosing “save target as”, though just clicking may give the same effect.  This spreadsheet needs Microsoft Excel, WITH the analysis toolpak add-in installed (to support random number generation).
NOTE!
Every effort has been made to ensure these programs are virus-free, but you should always trust your own virus-checker and keep it up-to-date.
Measuring Download
A stand-alone program to take pupils through basic measuring skills.  Save it to disk on your system and run it from there or direct from the web by clicking.  
Note for teachers, there is a hidden box in the top left corner, left- and right-clicking will skip forward or backwards one page.  
And the weighing example doesn’t work very well, sorry.
Random moles download
An Excel spreadsheet for creating random moles problems for GCSE and A-level.  Save it to disk on your system and run it from there, by right-clicking and choosing “save target as”, though just clicking may give the same effect.  This spreadsheet needs Microsoft Excel, WITH the analysis toolpak add-in installed (to support random number generation).

If you don’t have Microsoft Office, you should be able to see and print the Microsoft compatible files in Open Office, which is free and can be obtained here

For that matter, you can get most of them to open on a smart phone.
