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
They will set the temperature of the water bath themselves they will provide u with the water if specified or else will b dilutions

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

yes thats what ive been told by teachers
