SCIE1000 exam tips
Meaning of some terms used in exam question!
Reconcile
"!
Means to justify why the contradictory statements are reasonable and similar in a way !
"!
Find the relative number of this to that.
"!
The ratio of this to that. !
"!
Explain how each term mathematically affects the function
"!
Give the mathematical effect of each of the terms of the function (eg: amplitude, vertical shift,
phase shift)!
"!
Explain how each term physically effects the function
"!
Give the physical name of each of the terms of the function !
(eg: the y-int is the initial value of CO2, amplitude is how much the CO2 changes etc)!
"!
Estimate and explain your answer
"!
They don’t want you to calculate anything! Use some reasoning and deduce the answer based on
the pattern !
"!
Make appropriate points on the graph
"include the actual coordinates of any given figures before or the initial and final coordinates.!
Make sure you include the actual function of the graph on the top !
"!
What are some physical factors that can affect something? (3 marks)
make sure u have as many points as the marks that are very different from each other.!
"!
Find the time when this is blah
Don’t just find t=bah. If it is in a time period, find the exact date or year (2011) it will happen. !
Find main features of graph!
•is it rising or declining?!
•Is the rate of change (slope) increasing or decreasing?!
•Are there any identifiable shapes the graph is making (linear, exponential etc.)!
Comment on the suitability on the model
•explain how important the difference between model value and actual value is!
•Eg: the slightest difference in models when looking at pH can have a huge effect in real life
whereas differences in money will not. !
Making models and drawing graphs !
•when being asked to make a model, always find the units for each value including the constant !
•When drawing different functions all on the same graph, label the different functions with their
appropriate equations !

Document Summary
Meaning of some terms used in exam question. Means to justify why the contradictory statements are reasonable and similar in a way. Find the relative number of this to that. Explain how each term mathematically a ects the function. Give the mathematical e ect of each of the terms of the function (eg: amplitude, vertical shift, phase shift) Explain how each term physically e ects the function. Give the physical name of each of the terms of the function (eg: the y-int is the initial value of co2, amplitude is how much the co2 changes etc) Use some reasoning and deduce the answer based on the pattern. Make appropriate points on the graph include the actual coordinates of any given gures before or the initial and nal coordinates. Make sure you include the actual function of the graph on the top.
