The report must be typed and double-spaced. Each page should have your name and page numbers (as a header or footer). A formal report usually has the following sections: Headings should be used to denote the start of each section. These can be either titles or subheadings. Make sure that these are clear and easy to read. Use words in the text itself to indicate where different parts of the report begin. There is no limit to how many pages you can include in your laboratory report, but it is helpful if there is something on every page. For example, you could put a signature at the end of the document or include a table of contents. These do not have to be at the front of the report, but it is easier to find things when they are grouped together. It is also acceptable to leave some pages blank if there is nothing relevant for them to say. It is helpful if you identify the source of your information by writing "Source: xxx" on each page of your report. This allows others reading your report to know exactly where the information comes from. They may want to look up this source themselves. You should also try to be as accurate as possible with your figures. Including errors means that others will have to go through all your work again to check what was actually found. This is time consuming and errors can easily be missed.
