Representative Samples

    Hi guys



    I've been trying to prepare resources to cover the following points on the syllabus. Everything I search the web for appears to be presented in a complicated, detailed way. This is for GCSE Additional Applied Science. I wondered if anyone had anything that I could take a peek at please? I wouldn't be able to steal and use it without work, as I teach in a Welsh medium school so would have to translate. The bits I'm struggling with are:

    * explain how representative samples can be collected for analysis (e.g. water samples from streams/rivers, landfill sites or household water supplies).

    * state the information required when collecting and storing samples for analysis (e.g. water samples).

    * explain how to prevent the deterioration or contamination of a sample (water samples from streams/rivers or household water supplies).



    Any help with this would be amazing! I've been trying to do stuff on it all day and my brain is fried.

    A huge thanks in advance :)
