Top 10 CBSE Class 12 Biology Project Topics 2024

There are a wide range of topics that students can work with regarding their CBSE class 12 Biology Project Topics 2024. Candidates can go through the top 10 Project topics stated below.

1. Examine pH of Different Water Sample

Candidates in these CBSE Class 12 Biology Project Topics 2024 must study the pH level of Water and its properties. The pH level of 6.5 to 8.5 is healthy and safe for drinking. Water with a pH level of 3 to 5 is very acidic. Candidates must take the universal Indicator, Litmus paper, and different water samples and test the pH level for each of them. 

• Required Materials:  Various water samples, universal indicator and litmus paper.

2. Examine the Effect of pH on Seed Germination

The pH of the germinating medium influences seed germination. The quantity & type of different minerals, along with the quantity and quality of humus, hold the pH in soils. An exact level of pH is required for other seeds for maximum germination. The level of pH also impacts the growth and development, reproduction and metabolism actions of the plant.

• Required Materials: 125 seeds of various types, pH buffers, purified Water, Petri plates, and blotting paper.

3. Growing Yeast Process of Sugar Fermentation

This fungus is composed of eukaryotic microbes, i.e., cells with nuclei. Fermentation is the method of breaking down a substance by bacteria, microorganisms or yeast. Yeast starts working when mixed with sugar as it smashes down due to fermentation. As a result, it does not cause any reaction.

• Required Materials: 3 clear cups, sugar, Water, & marker pen.

4. Impact of Sugar on Bean Plant Growth

Candidates must assess if adding sugar to Water enhances plant growth and health. Sugar provides additional energy, and plants should grow stronger and healthier. It can be observed through visual inspection and comparison of samples with and without sugar.

• Required Materials: Bean seeds, distilled Water, Water with added sugar, cotton, and beaker.

5. Effects of Diet on Blood Glucose

Candidates must explore the correlation between blood glucose levels and diet in non-diabetic individuals, as high-carbohydrate meals increase blood glucose levels while low-carbohydrate diets decrease them.

• Required Materials: A glucometer for measuring blood glucose levels before meals and after meals for four non-diabetics.

6. Characteristics Affecting Nodule Formation in Legumes

Candidates must try to determine which factors are essential in the formation of nodules on legumes. The Rhizobium leguminosarum bacteria fix nitrogen for a vegetable plant in exchange for shelter and nutrients.

• Required Materials: Students will require 12 pots, 2 bags of vermiculite, a bag of potting soil, 36 snow pea seeds, Bacteria (Rhizobium leguminosarum), nutrient broth, an inoculating loop, and a Bunsen burner.

7. Proof Light Colour Affects Plant Growth

Students must observe how different light colours affect plants' growth.  Students must place plant pots under different boxes, let them grow, and record their sizes.

• Required Materials: 5 boxes with different coloured transparencies(red, blue, green, yellow and clear)on top and front, seeds, potting plant, and rulers. Students must place plant pots under different boxes, let them grow, and record their sizes.

8. Mechanism of Seed Sprouting

Students must determine bean seed growth speed in various germinating solutions. They should soak seeds in distilled water, hydrogen peroxide, malt, humic acid, potassium nitrate, and fish emulsion, then record germination results over 4 days. Then, they must record the results and observe the growth of seeds.

Required Materials: Students will require Plastic zip bags, different types of foods(fruits, bread, cheese, meat), spray bottles, and water.

9. Effects of Microwave Radiation on Different Organisms

Students must observe microwave radiation's effects on fungi, bacteria, and plant life. It is recommended that students use microwave ovens to heat certain ingredients and fats in the food by radiating high levels of energy. On the other hand, other substances remain unaffected.

Required Materials: Students will require Radish seeds, baker's yeast, Petri dishes with agar, paper towels, bowls, gloves, a microwave, a notepad and a pen.
