Exam Technique & Skills Flashcards
State/Name
one or two word answer
Describe
Detail (mugged/uniform)
Explain
Tell me why (uniform, because you are in school)
Predict (graph)
ruler, extend the line carefully
Percentage change/increase/decrease
difference/original x 100
Double axis graph
Slow down, colour code lines and axes, check correct line and axis each time.
Reliable
repeat what specifically, calculate an average
Compare
mention both
Function
the job (artery, carry blood away from the heart)
Structure
how it is constructed (artery, thick muscular walls, small lumen)
Average
total/number of numbers you have added
Average change
total change/total length of time
Conclusion
Aim - use the same wording
What is the relationship between X and Y?
X 1st, Y 2nd - If you increase X, what happens to Y. X will be the independent variable, Y the dependent variable.
What goes on the bottom axis of a graph?
The independent variable (NAPPY)
How many times bigger…
divide
Using data from the graph…
Guess what, use data from the graph
Using data from the table…
You really want me to answer that for you!?
You are reading from a graph - how will you do that?
Use a ruler and draw on the graph to be accurate
The graph has 2 axes and 2 lines - what is your first job?
colour code the axes with the lines
When looking at a results table, what always comes in the first column?
Independent variable
What two letter word should you avoid using in your answer?
it - give the name
List 5 possible variables that may need to be controlled in an investigation.
Temperature, volume of solutions, concentration of solutions, mass of solids, surface area of solids, diameter of samples, thickness of samples, light intensity, species of organism, time the experiment is left for, pH
When describing controlled variables what A word should you not use?
Am*unt
What do we call an experiment used to prove that the variable being investigated is responsible for the result?
A control
What are some reasons why an experiment may be left a period of time before measurements are taken?
allow time for diffusion
allow time for the reaction to take place
allow time for solutions to reach temperature
allow apparatus to stabilise
allow living organisms to acclimatise
When plotting a graph, what always goes on the x axis?
Independent variable
TRUE OR FALSE - A graph should always go back to the origin.
FALSE - only plot the points that you have in your results
If you are asked to describe a graph, what should be included?
labels, values and units
When describing a graph, how should you start your sentence?
AS THE (independent variable)
If you are asked to predict a result from a line graph, what should you do?
Extend the line using a ruler
If you are asked to predict a result in a table of results, what should we do?
look for the pattern between each reading
Why do we only change one variable during an experiment?
To make the experiment valid
