[iRuler]

Just stuck on question 61, part c of the 2007 science School Certificate paper.

I did this at school as a practice paper and I ended up getting a 4/6 so I just need help as to what I'm supposed to write to get 6/6.. any help would be nice

Thanks

Sorry about not being able to help, but I wanted to throw a question out there too. Could someone please post up answers or just a few points on the very last question of the exam? i.e. the satellite one, all sections of q 65. It would be very much appreciated!

Ehh.. No problem, I asked my friend last night on MSN at like 12 and he gave me an answer

Here's the Answer

Question 61 (continued)
(c) The scientists carried out a controlled experiment that supported the hypothesis:

Cane toads are attracted to UV light. ​

Describe a method for a controlled experiment to test this hypothesis. [FONT=&quot]
[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]you need set up a dome with 4 enclosed rooms[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]one room with uv light[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]another light by fluorescent lights[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]another with no light[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]and the final one with a red coloured light[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]introduce a large sample 50 to 60 toads into the dome[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]observe where they stay for a week[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]feeding them in the centre of the dome due to ethical reasons[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]and tabulate and graph your observations[/FONT]
[FONT=&quot] [/FONT]
[FONT=&quot]done[/FONT]

I just copied and pasted that into a word document so same colour etc...

Meh I think thats a perfect answer for it, If anyone can add more please do so

Perhaps repeat the experiment for reliability?

Ahh thanks

My teachers told me that you need to write down that you have to repeat an experiment atleast 5 times to get a reliable result otherwise you wont get any marks for the question.

So for that Well Repeat the experiment over 5 weeks with 50-60 New toads each week..

mmm my teacher said ten times to be on the safe side
and conduct the experiment over 2 months.

question.
When you're asked to describe the experiment, would you be allowed to set it out in an experimental design kind of way?

Like this:

variables controlled:
variables changed:

risk Assessment

method.
1.
2.
3.
4.
5


?
or like you megre all your ideas in one paragraph?

Same question here, althuogh I'm wondering whether u should have:

-aim
-hypothesis
-method
-results
-conclusion

or could you just merge it all into a series of dot points (as seen above) and get 6/6?

For designing experiements you don't include, results and conclusions.

You just have to state in your method how you will obtain results, what instruments your using and the units
