    Definitely. As long as you supported your answer with reasons and data from the graphs you could get 5 easily or even 6.

    Would an acceptable control variable for Q4 be to keep the same person seeing how long it takes for the cross to disappear after every test? (Some people have better eyesight than others).

    I assume that would be acceptable since it is true, so I think unless they're super strict you'll get the mark

    I thought it went 26.0 for 10g and was then 26.6 for 12g and 14g or did I read it wrong?!

    Did anyone else put add a polystyrene cup for the question about making the results more accurate by changing the apparatus used? Because a polystyrene cup is a good insulator so it would reduce heat loss. What do you guys think?
