These are potentially useful science downloads. I  make no promises about anything on them, but they have been useful to some people.
Atoms download
My structured program for learning about atoms.  This program supports learning for the Module C4 of GCSE OCR Gateway science.  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, more if you need to do the worksheets, but you can start at fifteen different points if you need to stop and return later.  There is a “secret” box near the top edge of the screen, click to skip forwards, right-click to skip backwards.  Note, it’s not always in the same part of the top edge.
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.
