Lab report discussion sections

hello students miss Watson here and

welcome to the ninth episode on how to

write a proper high school lab report

today we're taking a look at the

discussion section so first things first

it should be between one and five

paragraphs in length

now I understand that's a pretty big gap

depending on the lab you would choose

closer to one or closer to five so let's

say this is a small lab it comes maybe

near the start of a unit of study then

it would be closer to one paragraph if

it's a major summative lab it comes at

the end of the unit of study and the

whole point is to show everything you

know then closer to five paragraphs will

be better also if it's an inquiry lab

where you're making up the experiments

on your own closer to five paragraphs

would be better because you have a lot

more explaining to do it should relate

to the theory that you've learned either

in class or the research that you've

done should relate to the observations

and it should relate to the analysis so

here your discussion discussing all the

information that you found and relating

it back to the theory should be accurate

based on the actual results that you

obtained so if your observations section

gave you certain numbers you analyzed it

you got a final result your discussion

should be based on that result even if

you know what's wrong that's okay

discuss based on that result and then

maybe analyze why that was the wrong

result but you need to have your lab

report based on what you actually

obtained in your results in your

analysis it should be written in the

past tense and it should be written in

the passive voice

so again passive voice is to avoid

personal pronouns like I me we us and so

on here's an example instead of writing

we realized that the size of measurement

of the beats was a major source of error

for us so that has to

no pronouns that we want to get rid of a

better statement would be the size

measurements of the beats was a major

source of error so that would be in the

passive voice and it gets rid of those

personal pronouns now there are two

types of labs that we'll look at

standard labs and inquiry labs for a

standard lab then the majority of the

marks are just based on showing that you

understand why the results that you

obtained why you actually obtained them

so showing that you understand the

theory that you learned in class and in

your research and applying that to

understand why you obtained your results

for an inquiry lab in addition to that

you still need to include that

information you're also going to include

information on sources of air and don't

forget to explain that error don't just

tell me sources but explain why that's

error and then also the strengths and

limitations of the lab so strengths why

was this a great lab what did you do

well limitations what didn't go so well

and how could you improve upon that for

next time

and then lastly some labs will include

discussion questions

I don't include them as often as some

other teachers but many teachers will

include them for every single lab so

obviously some of your labs in my class

or maybe many of your labs in other

classes will have discussion questions

those also go in the discussion section

and your marks are awarded for complete

and accurate answers also the highest

marks if you're really looking to get

those top marks on your lab you need to

show a high level of comprehension and

insightful details so that goes back to

doing additional research rather than

just what we've taught you in class and

comparing it to the results that you

obtained all right that's all for now

bye bye
