Making Use of the Questions
The questions and practical work sheets are best used by
opening the corresponding PDF file. For this you will need to access the free
download, Adobe Acrobat Reader.
Once viewed in Adobe Acrobat reader the files can be saved and printed.
There is also an HTML version of each biology question which can be saved from screen. However, for those questions which included images, each image needs to be saved in order to work with the HTML file. The advantage to this method is that the questions can be answered on screen by calling the HTML file into a suitable word processing programme. Work can then either be printed or e-mailed to the teacher (as a .zip attachment if there are images). If the work is to be printed remember to put page headings on each separate page.
A Note About Spelling
We have tried to be consistent with spelling! The Open Door Web Site uses British spelling in general. The team, however, is multi-national and there may be occasions when US spelling has been used.
