    Mr P
    In our lab report on heart rate do we need to include the variables?

  2. malisha says:

    the solutions for the electricity revision sheet isn’t coming up?

  3. Sabree Dorlandt says:

    Mr P,
    can you please explain to me what Ohm’s law is? i was away for that lesson and don’t understand it.


    • Mr. P says:

      Ohm’s law is the mathematical relationship between voltage, current and resistance.

      The formula is Voltage = current x resistance (abbreviated as V=IxR where I is the current)

      Typical question: What is the voltage of a light globe that has 2A flowing through it and 10 Ohm of resistance?

      V = IxR
      V = 2 x 10 = 20 Volts

      Hope that helps!

  4. Jeesmon says:

    Mr Patterson,
    Please put on the answers for the revision sheet because I actually dont get half of the questions.

  5. Jeesmon says:

    Finally you posted outcomes 11, 12 and 13 on.

    And how does double glazed glass work as an insulator again?


  6. Maheera says:

    Mr Patterson can you please post the answers to the Physics Heat Revision. Thanks

  7. Dominique says:

    Mr Patterson,

    Where is the sheet that tell us about the ‘Chimney Modification’ assignment? I tried to find it on the website but I can’t. Would you be able to print a copy out or email me the pdf or tell me where to find it.

    Cheers Dominique

  8. Pushan Desai says:

    Mr.Patterson where is the chimney modifications sheet on the website??

  9. Sarah Lee says:

    nevermind i found it

  10. Sarah Lee says:

    actually forget that it was a mistake do you have the answers for the revision sheet??

  11. Sarah Lee says:

    How do you do mark and recapture methods with ratios? its in revision sheet number8 and 9

  12. Emily Worthingtob says:

    Mr Patterson,
    Could you send me some extra worksheets to review for the Exam on Tuesday?
    Worksheets to include Chemistry, Physics and Biology.
    Thank You

  13. Jeesmon says:

    Mr. Patterson
    Would you please check if my ecology textbook is with you by any chance. Because it is not at home. I think the number is 101.

  14. kaveen says:

    hey sahan do you have my book i need it

  15. kaveen says:

    hey jeesmon do you have my science book the number is 104 if you have it could you plees tell me

  16. Jeesmon says:

    Oops sorry! its actually written here as outcome 2

  17. Jeesmon says:

    Mr P, the outcome you gave at school today is not the same as the one on the webpage.
    We havn’t learned the one in here yet.

  18. Jeffrey Chua says:

    Mr Patterson can you post a copy of the investigation sheet i left it at home

  19. Jeesmon says:

    What are you meant to write in an evaluation?

    • Mr. P says:

      Evaluation after conclusion yes.

      Comment on the validity and reliability of the experiment. Offer ways to improve upon it. But not “We should work better as a team”!

  20. Jeesmon says:

    Mr P, In the lab report, isn’t the evaluation meant to be after the conclusion?

  21. Mr. P says:

    Atomic number of 19 (number of protons)
    Mass number of 39 (number of protons + neutrons)

    The placement of these numbers can vary between books. Sometimes mass number is on top. Sometimes atomic number is on top. The trick is that mass number is the bigger than atomic number

  22. Pushan says:

    On the Revision package, I was looking back and I saw that in Question 6 that Potassium has a Mass Number of 19 and on the book it says that it is 39. Which one is right?

  23. Pushan says:

    Is the test going to be similar to the revision package that we have?

    • Mr. P says:

      The test is based on the outcomes.

      The revision package is based on the outcomes.

      So the answer is yes and no. The questions may be different but the knowledge required to answer them will be the same.

  24. sahan says:

    wen do you use the brackets when your writing a formula ?

    • Mr. P says:

      When you have more than one polyatomic ion in the formula.

      CuCl2 does not have any polyatomic ions so no brackets

      NaNO3 only has one polyatomic ion (1 x NO3-) so no brackets

      Cu(NO3)2 has two polyatomic ions (2 x NO3-) so brackets surround NO3 to indicate there are two of them.
      ** note: all my numbers in the formulas should be small but I cannot write them small in this comment section.
