Control process Beetroot samples: The same size beetroots will be used throughout the experiment this is to ensure that the impact of the temperature on every sample will stay the same‚ i.e. if having a bigger beetroot sample less pigments will be released into the test tube at lower temperature‚ or having a smaller beetroot sample more pigment will be released into the test tube. This error will change the results of the experiment at large. Therefore it is important to insure the sample sizes

(37’C)‚ a ruler‚ 2spatulas Materials: 1 gram of “Super clean” and “Magic power” washing powder‚ distilled water‚ iodine solution‚ a starch agar plate Procedure: i. Drill 3 identical wells on the starch agar plate by a cork borer ii. Weigh 1 gram of “Super clean” and “Magic power” washing powder separately using the electronic balance. iii. Dissolve the measured washing powders with 4mL distilled water in 2 test tubes respectively.. iv. Labeled the wells on the underside of the dish of agar

beetroot and its cells. My earlier experiment suggest that as temperature increases the integrity of the beetroot cell membrane will be destroyed and a subsequent release of beetroot pigment will be released into its surrounding milieu(in this case distilled water). In the experiment I will examine if my hypothesis (above) is correct. In order to conduct this experiment I would choose a dependent variable as well as an independent one. The independent variable is the temperature at different degrees

After the mixture from part (a) has separated‚ turn on the suction valve and then slowly pour the mixture through the filter in the Buchner funnel. Be sure to completely empty the beaker (use distilled water if necessary to wash the precipitate from the beaker). f.) Wash the precipitate in the filter with two 20-mL portions of distilled water. Allow the suction to continue for several
