The pressure of performing best as per personal capabilities blankets most of the students. While subjects like Maths and English concentrates only on theoretical knowledge, subjects like Physics, Chemistry, Biology, Computer Science, Physical Education, etc, require candidates to prepare for excruciating practicals as well making this battle a tough one! Through this blog, we will be sharing some tips and tricks which are definitely going to help you in hitting a great in Biology practical. 

Marking Scheme of Biology Practical Exam for Class 12th

The theory exam for Physics, Chemistry and Biology are for 70 marks, leaving out 30 for practicals. From the beginning of a session, candidates are trained to ace during the final showdown. Regular classes for the same are arranged by the school authorities in well-equipped laboratories in the supervision of the teacher. Depending upon the experiment, a marking scheme is prepared for the board exam, here is a breakdown for Biology practical

List of Experiments 

In the Biology practical syllabus of Class 12th, there are numerous experiments which are mentioned. A student must have carried out each experiment ac couple of times, in order to have knowledge and skill to excel in the exam. Leverage Edu has compiled a list of important topics that a class 12th bio student cannot afford to miss while planning to prepare for examinations: 

Experiments

  • Collect and study soil from at least two different sites and study them for texture, moisture content, pH & water holding capacity. Correlate with the kinds of plants found in them.
  • Prepare a temporary mount of onion root tip to study mitosis.
  • Study the effect of different temperatures & 3 different pH on the activity of salivary amylase on starch.
  • Collect water from two different water bodies around you and study them for pH, clarity and presence of any living organism.
  • Prepare a temporary mount of the onion root tip to study mitosis.
  • Isolate DNA from available plant material such as spinach, green pea seeds, papaya, etc.

Spotting

  • Prepared pedigree charts of any one of the genetic traits such as rolling of tongue, blood groups, ear lobes, widow’s peak and colour blindness.
  • Flowers adapted to pollination by different agencies (wind, insects, birds).
  • Identification of stages of gamete development, i.e., T.S. of testis and T.S. of ovary through permanent slides (from grasshopper mice).
  • Two plants and two animals (models/virtual images) found in xeric conditions. Comment upon their morphological adaptations.
  • T.S. of blastula through permanent slides (Mammalian).
  • Meiosis in onion bud cell or grasshopper testis through permanent slides.
  • Common disease-causing organisms Like Ascaris, Entamoeba, Plasmodium, Ringworm through permanent slides or specimens. Comment on symptoms of diseases that they cause.
  • Two plants and two animals (models/virtual images) found in aquatic conditions. Comment upon their morphological adaptations

Preparation Tips for Biology Practical

Follow the Stepwise Guide
The student must note down a series of steps to be followed to conduct the experiment before carrying it out. Because different practical topics of Biology requires a different approach.

Following the stepwise guide is always beneficial!

Practice Diagrams and be thorough with Terminologies
When preparing for the Biology practical exam, students must practice diagrams very well. Students must be well versed with the important terminologies used in Biology and can use flashcards to remember and revise important terms and try to draw diagrams many a time so that they can draw a diagram at faster speed during the practical exam.

Confidence is the key!
During the Biology practical exam, the student must remain calm and confident to face any question provided by the examiner during the examination related to the experiment or anything that is under the Biology syllabus. Being confident enough during the exam is the only way to score excellent scores in the practicals.
