W mans covering the new syllabus
W video frl
god bless you dan, hope lifes good man!
My fav RUclipsr frl
Thank you for your videos, please keep uploading it helps a lot.
Thanks for this video 😊
Instead of chicken liver can I use a potato?
Yes as it also has catalase
Very well explained and straight to the point. Thank you!
What concentration of hydrogen peroxide should I use
I used 30%, but you can also use 3% as it is easier to obtain, will just require more drops

@@drott1722thanks smmmm
did you watch oppenheimer yet?
Only thing that you could improve on is making it clear which topics are HL! Thanks Mr Rott!
I only teach HL so everything I produce is focused on HL
W mans doing gods work
ngl your videos are insanely underrated- you cover the ib book by the page- rlly saving lives here 🙌
So helpful tysm!!! -Sam and Chris
Hi, I'm still confused how to collect database which I mean statistical data , plus my research question is "How does the change in temperature (70°C, 75 °C, 80 °C, 85 °C, 90 °C) affect the rate of the decomposition of ammonium carbonate? " For example, does the quantitative data has to be copy paste from a resource or what?
Thanks so much!!
Do your videos included HL areas of the units?
Yes they do
You are quite literally the BEST
subbed!
Junior dp1 student here. Looks like i’ll be visiting this channel quite a bit over these next two years
Super helpful channel defo gonna reccommend to my friends!
great video, thank you!
I love these videos would be great if you had more on the channel really helpful
More to come!
Thank you!
good video, though i think that salt water flows less easily than fresh water
Than you so much for the lesson Mr. Rott.
Thank you!
life saver.. i just started ib and nothing like bioninja or anyother resource is updated
same!! its so hard to find any study resources
I'm glad you're back! great video
Thanks Kevin, more to come soon
straight to the point, thank you
Your video was very helpful. Clear, concise, straightforward.
So that's why sanitizers are always 99% effective
Thank you very much
Nice way of delivering 👌🏻
Studying for my exam in a few weeks! For anyone else, keep in mind he forgot to mention the emergent property which is basically when cells work together, a greater function emerges (heart pumps blood, lungs expand, etc).
what buffers did you use or can you give some buffer examples to use while doing this experiment
I purchase stock pH buffers from Carolina Biological Supply. You can also do some google searching to find how to make buffers at home
do i need uncertainity if i have a database IA?
Only if the database provides it. If it does not, be sure to address that they were not provided
Thank you so much, I was finding this section so overwhelming, but this really helped make everything more clear
Thank you
Fantastic!

Hi, I did my IA on the effect of pH on plant growth, but I'm unsure how to formulate my hypothesis and which stats test to use. How would you formulate a hypothesis for a pH experiment?
Edna, not knowing completely your question and experimental design, my general recommendation would be to ensure you have a wide range (at least five) pH values tested and a minimum of five trials for each. This would enable you to create an XY scatter graph and correlation test for your analysis. Good luck.

Hi, I was wondering that app/program I should use to make my graph. Would excel suffice or do I have to pay for other programs like Logger Pro? Thanks.
I would recommend using Excel or Google Sheets. Logger pro is to be used with Vernier probes and really is just used to collect data, not analyze the data. If you have access to a probe, I highly recommend using them for your IA data collection: digital data collection is always best.
Great teaching and sharing. Can we plot individual data plus SD, rather than mean value plus SD?
Yes, you could. However, a single trial and individual values are not well statistically supported and thus, at least for IB, you should conduct at least five trials and use the average of those.
Hi. What concentration of catalase should i use for this experiment if i have pure aqueous catalase?
Sorry, I can't give a straight answer on this. In using blended chicken liver, I don't know the exact amount of catalase in the solution. I always test the solution with various pH levels before class to ensure the concentration is appropriate. Assuming you are also using Vernier gas pressure sensors, I would recommend doing the same. Good luck
@@drott1722what concentration of hydrogen peroxide did you use ?
So don’t boil raw milk?
That doesn’t matter. By the time the milk reaches your small intestine, the lactase that you’re body produces will be perfectly capable to break down the lactose.
I love you
