    water... take the sample of soil place it in oven measure the intial content ie mass and after heating allow it dry..measure the diffference in mass which gives u moisture content.
    light........use light sensors

    I wrote that to measure water you get a sample from the soil and weigh it, then you dry the sample and weigh it again.
    Then to measure light use a light meter.
    I did add too that this measurements should be repeated to ensure reliability since they can vary depending on the season of the year or the time of the day. Just in case since they were 3 or 4 marks (can't remember exactly) haha

    For the detection of cancer on blood sample i wrote that you get a blood sample and compare to a healthy blood sample, which will have the normal number of white blood cells, platelets and red blood cells and plasma cells will have a normal shape. Therefore you count how many they are in the blood sample and depending in the number of them and shape of plasma cells, they would have cancer or not.

    My son sat unit 4 Biology today and sits Unit 4 Chemistry on Thursday. He said today's paper was like nothing he had seen before. A lot of suggest questions and less knowledge based. Over his 5 x AS levels he averaged 90%. He was so upset about the exam today. He didn't even finish the paper. One very upset son
