    Hey guys so i did the bio exam on tuesday and the b2 paper had that question on magnification right. I dont remember it exactly but it was asking to use a ruler and measure the scale and find the magnification. So i found that people in my year put several different answers :confused:
    In the poll i included the most popular answers. Vote in the poll for what answer you put, if it is something else please say what you put in the comments.
    It will be interesting to see what the most popular answer is.

    AND GOOD LUCK FOR THE CHEMISTRY AND PHYSICS EXAMS
    although im completely dreading it as i do triple and still haven't finished recapping c2 !!!

    4cm on the diagram = 0.1mm in real life, 4 cm = 40mm, to get 40 from 0.1 you times it by 400. Therefore the magnification is 400.

    how about the transect one the 6 marks it was quite easy but i guess i missed out 1 mark
    i found that okay and understood it so quickly did the rest of the paper and did the 6 marker at the end.

    I wrote to pull the tape measure from the shady area to the sunny area to make a transect
    then at regular intervals e.g every 1m use the ruler to measure the size of the leaf of whatever it was
    at each interval also use the light intensity thing to measure the sunlight and record the size and light intensity in a table
    to this until you reach the sunny area
    then can carry out the experiment couple more times to get reliable results.
    If the results show that the size of the leaf decreases as light intensity increases the hypothesis is proven right.
    I didnt mention quadrats because it wasnt in the equipment list.
