im doing my as level biology coursework and i want to say that 'using a syringe would be more precise than using a measuring cylinder because the syringe has a smaller measuring scale therefore i can measure closer to the amount i need' but dont know how to say it in scientific terms help!

Because the syringe has finer gradations on its measuring scale than the measuring cylinder the error involved in using the syringe to measure the volume of fluid is less than the error when using the measuring cylinder.

Because the syringe has finer gradations on its measuring scale than the measuring cylinder the error involved in using the syringe to measure the volume of fluid is less than the error when using the measuring cylinder. The main difference is the gradations on the measuring scale.

The use of a syringe is much more accurate than a measuring cylinder, due to the smaller volume and control of the syringe output.

What you wrote is easy to understand but if you want to refine it a little more, here it is:
" Use of a syringe to measure small quantities of liquids gives more precise results than a measuring cylinder because of the former's smaller diameter and consequent longer scale with more divisions, thus minimising error."

Well, what everyone else has said is fine, so pick one of them. But one thing that would help you out even before trying to rephrase that, would be to know the difference between "precise" and "accurate".
This is something teachers will ask you in beginning science classes.
Precision = the degree of refinement with which an operation is performed or a measurement stated. So, for example, the number pi. If your calculator displayed pi as being 3.14, it would not be as precise as one that can calculate pi to
3.14159265.
Accuracy = degree of conformity of a measure to a standard or a true value (how close to the actual value). So if you had the same calculator that could calculate out to the billionths, but displayed pi as 3.20000000, it would be inaccurate.
Hope this clears the difference so you can come up with a better summation.

Try some thing like;
.using a syringe would be more precise than using a cylinder because it uses smaller units of calibration; therefore I can measure with more accuracy'.

What you mean is it has a larger measuring scale. That's why it's easier to read and more accurate.
Say, "It would be better to use a syringe than a measuring cylinder since its calibration is on a larger scale, so making measurement more accurate."

Personally, I'd recommend Orinico's answer. But I just thought I'd add a bit of general advice to writing scientific reports: don't use the word "I". So instead of saying 'I could measure more precisely', say 'a precise measurement was achieved'. Orinico has done exactly this, but make sure you use it in the rest of the work!

This is fine, right? I mean, anyone will understand this, which I think is something lacking from general sciencespeak.
