Tips for Practical Papers
Paper 3 Tips: Practical Test
• Do not panic if the context of the practical experiment appears unfamiliar. Where
appropriate the question paper will tell you exactly what to do and how to do it.
• If you find yourself in real difficulty setting up your practical equipment you may ask
your supervisor for help, although you may lose one or more marks for this.
• There are a number of things that you can do to save time: Draw a single table for
your results in advance of taking any readings and enter your readings in the table as
you take them (so that you do not waste time having to copy them up later). This is
also important because you must record all your raw readings before you calculate
and record any average readings. If the number of readings that you need to take is
indicated in the question paper do not waste time by exceeding this number. Repeat
your readings, but remember that it is only necessary to repeat them once (so that
you have two sets of values) - do not waste time repeating them more than once. • All the raw readings of a particular quantity should be recorded to the same number of
decimal places which should in turn be consistent with the uncertainty in the readings.
• The uncertainty in a measurement can sometimes be larger than the smallest interval
that can be measured by the measuring equipment. For example, a stopwatch can
measure time to a hundredth of a second, but human reaction times will mean that
the uncertainty in the reading given by a stopwatch is (typically) 0.1s to 0.4s.
• Each column heading in your table must contain both a quantity and its unit. For
instance if you have measured time “t” in seconds, your column heading would be
written as “t/s” (“t in s” or “t(s)” would also be acceptable). The quantity or unit or both
may also be written in words rather than symbols.
• The number of significant figures used in a derived quantity that you calculate from
your raw readings should be equal in number to (or possibly one more than) the
number of significant figures in the raw readings. For example, if you measure
potential difference and current to 2 and 3 sig figs respectively, then the
corresponding value of resistance calculated from them should be given to 2 or 3 sig
figs, but not 1 or 4. If both were measured to 3 significant figures, then the resistance
could be given to 3 (or 4) sig figs.
• When drawing your graph, do not forget to label each axis with the appropriate
quantity and unit, using the same format for expressing column headings in a table.
Choose a scale such that the plotted points occupy at least half the graph grid in both
the x and y directions. The x-axis scale should increase positively to the right and the
y-axis scale should increase positively upwards. Use a convenient scale such as 1, 2
or 5 units to a 2cm square as you will then be less likely to make a mistake with the
position of your plotted points and it will be easier for you to read off points from your
graph if you are calculating the gradient or finding an intercept.
• All your plotted points should be on the grid; points in the white margin area will be
ignored. Plot all your observations and ensure that they are accurate to half a small
square. A fine cross (or an encircled dot) drawn with a sharp pencil is acceptable, but
be careful not to obscure the position of your points by your line of best fit or other
working.
• When drawing your line of best fit, ensure you have an even balance of points about
the line along its whole length. If it is a straight line, use a clear plastic rule so that
you can see points on both sides of the line as it is being drawn.
• Show all your working when calculating a gradient. It is helpful to draw the triangle
used to calculate the gradient on the graph and to clearly label the coordinates of the
vertices (accurate to half a small square). These values can then be used in the
gradient calculation. The length of the hypotenuse of the triangle should be greater
than half the length of the graph line.
• If you are required to give a value for the y-intercept, it may be possible to directly
read it off from your graph from an axis where x=0. If this is not possible you can
instead calculate the y-intercept by using the equation of a straight line. In this case
you should substitute into this equation a pair of x and y values from your line of best
fit along with your calculated value of gradient.

Moment. Wooden rod pivoted with nail with stand,
masses hanging at both ends,position of pivot has to change for different sets of readings

Q1

Q2
Long tube is connected with a syringe with stopwatch flow rate of water measured either by changing quantity of water or length of tube
Errors
1 two sets of readings not enough to conclude about relation
2 parallax error in measuring volume of water / length of tube
3 hard to see level of water in the syringe (both are white)
4 its hard to maintain same pressure at the plunger of syringe
Improvements
1 take several sets of readings and graph is plotted
2 meter rule must be close to object and line sight perpendicular to scale of it
3 water should be dyed to make it visible in syringe
4 a weight should be placed at plunger to move it down in syringe uniformly or other suitable mechanical method be adopted

Apparatuses:
-First Question
>Rod Stand
>50 cm wooden metre rule
>Brick
>Spring Balance
-Second Question:

>Syringe
>Scissors
>Water Beaker
>Thread Ball
>Small tub(double Bowl size)

is it easier now !!!???
