in Berry Experiment (Experiments & PEKA)

The following list of PEKA experiments for SPM Biology Form 5 from Berry Berry Easy shows all the important information that you need to know regarding the experiment before conducting it, such as page number on the textbook, title, aim/objective of study, problem statement, hypothesis, variables, materials, apparatus and technique used. So, it is highly encouraged that students read all of these experiments from Chapter 5: Inheritance conducting the experiments so as to be better prepared. So do read this post.
