very easy. aiming for 95+ what was the magma movement under the earths crust??? i thought its convection currents but it wouldnt fit so i just put current ??

easy test. some multiple choice qs a little hard but overall hopefully 85+

V = I x R Voltage = Current x resistance if voltage is constant, current increaes, resistance decreases if voltage is constant, current decreases, resistance increases. eg. 10 volts = 5 amps x 2 ohms. if amps increase to 10 then ohms (resistance) decreases to one.

u got control mixed with controlled variable. ur definition is for controlled variables. control is a test under normal conditions to compare your tests with/

normally by the time i answer someone else has lol. anyway the first one is quite easy. circle is 360 degrees from the centre. 720 is twice 360. so all u do is half everything to get it to the right aount (ie 1/2 = 2/4, 140/720=70/360. so expenses would be 70 degrees out of 360 degrees...

cant be bothered writing this but there is some good info on writing a method here: Science SKILLS answer. | Facebook

they are water resistant and fire resistant and flexible (?) PLZ someone answer this: 3 observations is a metal+acid reaction (eg. magnesium+HCL). hint: bubbling is one. now name the other 2.

Line of best fit is there in science so that there are not more than one gradients. First plot all the X s on the graph, then see whether a line is more apppropiate or a curve. try to draw the line/curve in a way that it goes through most points but not necessarily all. for a curve, go smoothly...

look above

not sure but i think it breaks thy continuous cycle of heating and releasing light. is this in our syllabus?

Evaluate an impact of an environmental problem. In your answer, show how science can help reduce the impact on society and the environment. (6 marks, SC 2007 Question 64)

sorry my bad it was a sample paper not the real thing but thanks for the answer anyway

yes done the same one. lol only got 86% and came first in my school. i lost 5 marks on the last 2 pages because i didnt see them until the last 3 minutes. i thought the page with the 4/5 marker questions was the last page doh!
