They will set the temperature of the water bath themselves they will provide u with the water if specified or else will b dilutionsm
my teacher didn't say anything about preparing water bath, only hydrogen peroxide and the equipments like in the specimen paper, so he guessed it will be the effect of different concentrations on the number of bubbles
whether its serial dilution or effect of temperature, it won't really matter, at least we knw about counting the number of bubbles, so then we can prepare ourselves for techniques neededThey will set the temperature of the water bath themselves they will provide u with the water if specified or else will b dilutions
I was told that it could probably be counting bubbles by changing temperate of the beaker or by changing concentration of H2O2
But my teacher told that it is about yeast !!!!!!!
yess it includes hydrogen peroxide, my teacher who prepares the lab equipment said so, and the test might be like the one in the specimen where u have to count the number of bubbles per min and see the effect of concentration on the number of bubbles, so most probably there will be serial dilution , and the slide include a dicot stem where u have to draw
what yeast experiment might come? :S any links to a past paper that might be similar ? please

that ques was so weird:/..we had to make lines of how many bubbles formed..i did it with pencil too but wrote the total no. with penGuyss a havee a very important question, in the tables were we had to do, i wrote my results in pencil, but i wrote a report to the CIE asking them not deduct any marks and gave them my reason, do u think ill get deducted?
Yes we had to do this, but am on about the table u had to make to insert ur results the one just right before the question of inaccuracy.that ques was so weird:/..we had to make lines of how many bubbles formed..i did it with pencil too but wrote the total no. with pen

Yes, i wrote the answers in this table in pencil, will they deduct marks?for that we had to show the time and bubbles for hot temp and same for cold temp also
Yes, i wrote the answers in this table in pencil, will they deduct marks?
But i wrote them a report that i didnt have time to go over it with pen, so i hope they wont deduct muchi think they will not sure:/...our teachers always told us to write tables with pen
