Biology Investigatory Project Class 12 Samples

The investigatory project domain of the Class 12 Biology ranges from fermentation to the study of effects of radiation on the living organisms. Some of the project samples along with the materials required and their overview is given below.

pH Effect on Seed Germination Process

Overview: The pH of the germination medium has an impact on seed germination. The pH of soils is determined by the quantity and quality of humus, as well as the type and amount of different minerals. For optimal germination, various seeds need varying pH levels. The plant’s ability to reproduce, grow, and regulate its metabolism are all impacted by the pH level.

Materials Needed: 125 seeds (of different types), distilled water, pH buffers, Petri dishes and blotting paper.

To Study the Growth of Mold

Overview: A fungus called mold grows when it gets water and nutrients. Mold grows on stale food items such as bread, fruits, cheese, meat, etc. at home.

Materials Needed: Plastic zip bags, different types of foods (cheese, meat, fruits, bread), spray bottle, water.

Effect of Microwave Radiation on Different Organisms

Objective: To study how the microwave radiation affects bacteria, fungi, and plant life

Overview: Due to the high energy levels that microwave ovens emit, some food components including lipids become heated. Other chemicals are not impacted.

Materials Needed: Baker’s yeast, agar-filled Petri dishes, paper towels, bowls, gloves, microwave, notepad, and pen are needed along with radish seeds.

To Investigate the pH of Water Sample

Overview: It is important to keep an eye on the chemical composition of the water we use or drink on a daily basis. Water with a pH between 6.5 and 8.5 is acceptable for human life and health. The pH range of 3 to 5 is too acidic for most species to survive. Fish perish below pH 4.5, and few invertebrates that can withstand acidic conditions live. A pH of more than 8.5 is also too basic for most species to survive.

Materials Needed: Water Samples, Litmus Paper, and Universal Indicator

To Study Growth Speed of Sprouting Seeds

Objective: To determine the speed of growth of bean seeds in different growth solutions

Materials Needed: 5 sets of 10 bean seeds each, distilled water, fish emulsion, coffee filters, hydrogen peroxide, malt, humic acid, potassium nitrate, cups.

Methodology: The bean seed should be soaked in several cups that contain fish emulsion, distilled water, hydrogen peroxide, malt, humic acid, and potassium nitrate. Stow the seeds in between coffee filters to keep them damned. Keep track of the germination outcomes for four days.

To Study the Process of Sugar Fermentation

Overview: Yeast belongs to the class of fungi and is composed of eukaryotic microorganisms, which means that its cells have nuclei. The process by which bacteria, microbes, or yeast break down a substance is called fermentation. When sugar is combined with yeast, fermentation causes the sugar to break down. There is no reaction from yeast when combined with water or when used alone.

Materials Needed: 3 clear cups, sugar, water, permanent marker

Study the Effect of Sugar on Bean Plant Growth

Objective: To ascertain whether adding sugar to watering plants resulted in their growing stronger and healthier

Overview: One source of energy is sugar. When you add sugar to water when you water plants, the sugar gives the plants more energy, which should help the plants grow stronger and healthier. Visual inspection and measurement of plant samples with and without sugar could be used to observe this.

Materials Needed: Bean seeds, cotton, beaker, distilled water, water with added sugar.

Study the Factors Influencing Node Formation in Legumes

Objective: To determine the factors important nodules formation in legumes.

Overview: The bacteria Rhizobium leguminosarum fix nitrogen for legume plants in exchange for a nodule that houses and feeds the bacteria.

Materials Needed: Twelve pots, two bags of vermiculite, one bag of potting soil, thirty-six snow pea seeds, nutritional broth, an inoculating loop, bacteria (Rhizobium leguminosarum), and a Bunsen burner.

To Study the Effect of Diet on Blood Glucose

Objective: To find out the relationship between blood glucose and diet in non-diabetic people.

Overview: Blood glucose levels increase in individuals who have eaten a high-carbohydrate meal. In the same way, a low-carb diet would result in low blood glucose.

Materials Needed: Non-Diabetic People (at least 3 persons), a glucometer

To Study the Effect of Light on Plant Growth

Objective: To study how the light affects the growth of plants

Materials Needed: Five transparent boxes (red, blue, green, yellow, and clear) with seeds, a potting plant, and rulers on top and front.

Methodology: Plant pots should be placed beneath various boxes to allow them to grow and be measured.

Impact of Class 12 Biology Practical Marks in CBSE Board Result?

In the CBSE Class 12 Biology exam, practical marks play a significant role in your overall score. The total marks for the subject are divided between theory and practical components as follows:

Theory (70 marks): This is assessed through the written board exam.
Practical (30 marks): These marks are based on the performance in practical exams conducted at the school level under external supervision.
Importance of Practical Marks:
Boost to Overall Score: Practical exams generally tend to be easier compared to the theory exams, providing students with an opportunity to score well and enhance their overall result.
Contribution to Final Grade: Since practicals constitute 30 marks, performing well can significantly impact your final grade.
Skill Assessment: The practical exam tests your ability to perform biological experiments, understand lab techniques, and analyze results. It reflects your hands-on knowledge, which complements theoretical learning.
Preparation for Further Studies: For students planning to pursue biology-related courses (like medicine, biotechnology, etc.), practical skills are essential. Scoring well in practicals indicates a good foundation.
In summary, practical marks can make a noticeable difference in your final score and can help improve your grade in the subject.
