State the stock solution concentration and the the new concentration(s) you want to make. Mention the formula to do the calculation and explain each symbol. Describe the volume of stock you use and the distilled water volume. In your description mention suitable apparatus,such as measuring cylinder and beaker.
David de lecturer Ok so if i want to do simple dilution using stock solution of 0.5 gdm-3 using the formula c1v1=c2v2 to make say 0.4 g dm-3.what would be v1 and v2?
you have to fix a v2 or find it from the question. It depends on how much of 0.4 u need for the experiment. You cant have both v1 and v2 unknown, one of them must be fixed.
Hi, I wouldn't say it's enough because it is just some basics of p5. You also have to study on statistical tests and of course, try a lot of questions until you are familiar with the answering techniques.
@@DBiologyClassroom thank u for ur response. Do u cover all the p3 and p5 topics? If not, do u recommend any yt channels? Since im a private candidate so i dont have anywhere to do these
@@yunussicakozul2223 you can check out my playlist for practical, I do cover some important things to know about them. As for other channels, I am not too sure about that as I never really watch myself 🤣🤣
The second part of paper 5 is the graph question, statistical test, etc. So there is no second part for this video, but I have made one video for each of the statistical tests, and there is one video on how to describe graphs too.
I wish you would've made all p5 videos in your playlist instead of putting videos of other channels. You describe really well but others are confusing. This time my teacher also didn't make us practice p5 and now i am clueless. All videos are confusing of other channels. After two days, we have p5 exam and I guess I am gonna fail now.
Hi, I am pretty sure you are looking at playlist created by other people because I don't have any playlist that includes videos from other channels... At this point you should just try as many past papers as possible to understand the marking scheme. All the best.
@@DBiologyClassroom should i look at experiments such as respirometer, chromatography, redox indicators for rate of respiration of yeast and statistical experiments such as chi square test, T-test and random sampling and practice some past papers. Will that be enough to get general idea of p5???
Great video, thank you so much!
I have my paper 5 exam in just a couple of hours, hope it goes well!!
All the best !
ayo u must be done with uni now

Thank you very much Mr, your video is very helpful.
May God bless you.
You are welcome ! :)
Awesome work man, I have p5 on 15th may :)
All the best !
Thanks guys!
@TheSheikhofPeace centre?
Haseeb khan please help me with full notes of procedure to solve bio p5...I have exam tomorrow
Could you elaborate on 3:30
Can you give an example of where we would need to prepare something’s before carrying out the experiment?
E.g. steps to ensure a set up is airtight, to calibrate an instrument, acclimatise an organism etc.
@@DBiologyClassroom thank you!
Great explanation man, short and simple.
Glad u find it useful !
Of course,since my P5 exam is today.
@@vinsukakannangara5389 mine is today..after a long time😂but each one's turn is ought to come
Thank you for your help it's very useful💐
You are welcome !
anyone here from the quaratine for ON examss

You are welcome!
Thank you, this was very helpful
You are welcome !
damnn watching this 2 hr before exam
All the best !!
Hi ur videos are really helpful could u make a video on autosomal linkage
Hi thanks. I will put that title in the queue :)
Can you explain how to describe serial or propotional dilution?
State the stock solution concentration and the the new concentration(s) you want to make.
Mention the formula to do the calculation and explain each symbol.
Describe the volume of stock you use and the distilled water volume.
In your description mention suitable apparatus,such as measuring cylinder and beaker.

I need to ask you few more doubts how can I contact you ???

Hello there I need help with a Biology paper 4
Thank youuuuuuuuuu sirrrrrrrrr
Welcome
Thank you so much
You are welcome !
This is for cie a level right?
yes
Have paper5 today😭any tips because never worked p5 in school first time
Skills that you need: 1. experiment planning. 2. Graph drawing 3. Bio-statistical test
@@DBiologyClassroom Thanks sir I was able to work the paper if you have time please check the paper 9700 52
this was so damn helpful thank u!
You are welcome !

@@samsyy-601 yup. Statistics and experiments are the two main things in paper 5
can you provide some sample answers
You mean discuss questions kind of video?
David de lecturer yeah i mean questions
How to tackle that specific question
And 1 or 2 complete answer as a sample for any question
