    What are they made of or something answer was DNA and protein :D

    I said genes and protein.

    I said genes and protein.

    99.5% sure its DNA and protein.


  • Registered Users Posts: 2,419 ✭✭✭WanderingSoul


    I was so happy with that paper. :D

    By the way, I said DNA and protein. :)

    Genes aré made up of chromosomes not the other way round :)

    Really relieved that this paper was not hard at all.

    What if you had both magnets hanging from strings and you said to push North to North?

    Yeah I said something like that for the experiment. I'm sure they'll give it to us, like I know it doesn't include a retort stand and any other equipment but it still shows that like poles repel and that was the purpose of the experiment.

    What was the liquid used to get rid of the green pigment in the leaf experiment?I said Alcohol:confused:

    Same. Pretty sure it is right.

    For the organ question I said eyes because about 80% of the eye is in your skull, so I think they have to accept it. The skull protects important parts of it like the optic nerve, etc.

    Overall i thought the paper was pretty good.
    just completely messed up that copper sulfate question:(

    Yes!;)
    It's almost fully alcohol so I'd say you'll get away with it!:P

    science is uber easy and we never have to do religion again....woo hoo.

    that paper was great imo! I'm just kinda worried bout the experiment with the magnets :/ sure hopefully it's only worth like 3/6 marks!

    What organs does the skull protect? I said the brain and the sensory organs? (eyes, nose etc.) I got kinda stuck on this one :/
    This question was quite tricky indeed :p I said brain and the spinal cord :pac:

    Wait, do you think I'd get any marks if I drew a diagram of two bar magnets with the south poles of each repelling? It said a 'simple experiment' so maybe??

    Maybe. The experiment is in the book and it sorta requires a retort stand. It enables the magnet to swing around freely. Unfortunately you don't get attempt marks in Science. But you'll get something :).

    I didnt read that Question properly and i wrote lungs and brain:(. So many in my class did that too....

    dont worry its only worth 3 marks!!

    I was looking back through the thread............there was a balancing equations question??


  • Registered Users, Registered Users 2 Posts: 6,840 ✭✭✭Luno

    I think that was just before the exam and someone was wondering how you done it... Didn't come up anyways thankfully!

    anyone notice the diagram where the stomach was in the guy's chest? :rolleyes:


  • Registered Users, Registered Users 2 Posts: 1,988 ✭✭✭Monsieur Folie


    There were 2 graphs as well, which is awesome. In science, graph's are like free marks! And the bar chart too.. It was suspiciously easy.


  • Registered Users, Registered Users 2 Posts: 2,326 ✭✭✭Scuid Mhór


    The exam was too easy. My teacher says he wished that they kept science on the old syllabus. I'm beginning to agree with him.

    Sure we have it done now. Don't ruin it for the younger generations. Or maybe do. They deserve it :rolleyes:

    It was a very easy exam not challenging at all!

    What was the answer to the cost of running the kettle, does anyone know? :)

    Good few in my class said €4.50 we could all be wrong though :p

    You see I got that, but I thought it was wrong! So I then changed it to 45c, but that still seems like a lot.:confused:

    How do you balance an equation?
    e.g. CaCO3 + HCl ---> CO2 + H2O + CaCl2

    I noticed it was in past papers but we never did it in class :confused:

    Balance the elements on either side:
    to balance this one just put a 2 before the HCl.

    CaCO3 + 2HCl ---> CO2 + H2O + CaCl2

    Then you have:
    1 Ca on either side
    1 C on either side
    3 Os on either side
    2 Hs on either side
    2 Cls on either side.

    Please stop :eek: Science is over and if I ever see a balancing equation ever again I will scream :cool:

    Not at all! Sure 450c is the same as €4.50! Examiners aren't that mean:p

    Book 1:There was a book where you had to write up all the mandatory experiments you were meant to have done over the 3 years. (Some schools just use a hardback to do this)

    Book 2:This was the green book we got a few months ago when we had to write up our one day practical experiments (on 2 of: "factors affecting the distance a toy car travels after rolling down a slope", "the best indigestion remedy" and there was one more on Biology, something about plants). It was in this book that you had to tick the boxes saying you had completed book 1.


    COURSEWORK PROCEDURE.

    over your 3 years of jc study you should have done 30 compulsory practicals, worth 10%. this is coursework A. you should have ticked off boxes in the little green sec booklet to show which of these experiments you have and have not done. then between january and april of this year you should have done 2 further major practicals, worth another 25%. the full reports for these should have been written into the same green sec booklets. these green booklets would have been completed some time in april, probably, and then collected by your teacher. they were kept in your school and are sent off with your actual science exam to be marked.

    now, regarding the coursework A, the 30 experiments. the dept. may require proof that these were actually done! this is where your hardbook notebook or report book comes in. over the 3 years you would have been completing reports on the experiments or filling in the report book. your teacher SHOULD have collected these from you in april also, and kept them. they SHOULD be kept in the school until next christmas, just in case there is any query by the dept as to whether the experiments were actually completed or not. ie do the ticks in the green sec booklet actually match the work done!

    interestingly, the department just require 'proof that the experiments were completed'. so, if instead of doing reports of the 30 experiments in coursework A, you could, in theory, submit video or photographic evidence for each expertiment!

    ok? :)
