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.

CBSE curriculum for class 12 includes investigatory biology projects which help the students to understand the fundamental theories. This blog will provide you with details on how to prepare a biology project for class 12 with some ideas topics and more. 

This Blog Includes:

Investigating the ph of a water sample, to study the effect of ph on seed germination , growing yeast: sugar fermentation, effect of sugar on bean plant growth, effects of diet on blood glucose, factors affecting nodule formation in legumes, does the color of light affect plant growth, the speed of sprouting seeds, how does mold grow, how does microwave radiation affect different organisms, format of writing biology project for class 12, sample biology project for class 12, other popular biology projects for class 12, biology projects for class 12.

It is important to monitor the chemical properties of the water we drink or use every day. The permissible pH of the water that is safe for our life and health is 6.5-8.5. If the pH is 3 to 5 it is too acidic for the survival of most organisms. Below the pH of 4.5, fishes die and only a small number of acid-tolerant insects survive. Likewise, a pH of more than 8.5 is too basic for the survival of most organisms.

Materials Required: Universal indicator, litmus paper and different water samples.

Aim: Seed germination is affected by the pH of the germinating medium. The amount and type of various minerals and quantity and quality of humus control the pH in soils. A specific level of pH is required for different seeds for maximum germination. The level of pH also affects the growth and development, reproduction and metabolism activities of the plant.

Materials Required: 125 seeds each of different types, pH buffers, distilled water, Petri dishes and blotting paper.

Yeast is classified as a fungus and is made up of eukaryotic microbes, i.e, they have cells with nuclei. Fermentation is the process of breaking down a substance by bacteria, microorganisms or yeast. Yeast gets activated when mixed with sugar as it breaks down due to fermentation. Yeast alone or when mixed with water does not give any reaction.

Materials Required: 3 clear cups, sugar, water, permanent marker.

Aim : To determine whether plants grew stronger and healthier with the addition of sugar while watering

Abstract: Sugar is a source of energy. When sugar is added to water while watering plants, the plants should grow healthier and stronger as they get additional energy from the sugar. This could be observed by visual inspection and measurement of plant samples with and without sugar for comparison.

Material Required: Bean seeds, distilled water, water with added sugar, cotton, beaker.

Aim: To investigate the relationship between blood glucose and diet in non-diabetic people.

Abstract: a person’s blood glucose level rises after consumption of a high carbohydrate meal. Likewise, blood glucose would be low if a person consumes a low carbohydrate diet.

Materials Required: Measuring the blood glucose level in 4 non-diabetic persons using a glucometer before meals and then one hour, two hours and 3 hours after eating.

Aim: To determine which factors are important in the formation of nodules on legumes.

Abstract: Rhizobium leguminosarum bacteria fix nitrogen for a legume plant and in return, the bacteria get shelter and nutrients in a nodule.

Materials Required: 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.

Aim : To observe how different light colours affect plant growth

Materials Required : 5 boxes with different coloured transparencies(red, blue, green, yellow and clear)on top and front, seeds, potting plant, rulers.

Title: Mitosis in Onion Root Tip Cells

Aim: To observe the different stages of mitosis in onion cells

Objectives:

• To understand the process and different stages of mitosis
• Prepare specimens of onion roots to visualise all stages of mitosis.
• Use an analytical technique to determine the relative length of each stage of mitosis.

Principle : Onion cells have 8 chromosomes. During cell division, the two strands of the DNA double helix separate, and for each original strand, a new complementary strand is produced, for the process of DNA replication. This is followed by the process of mitosis which assures that each daughter cell receives one copy of each of the replicated chromosomes. During this chromosomes pass through several stages of mitosis. These stages include interphase, prophase, metaphase, anaphase and telophase.

Materials needed: A fresh onion, small beaker, Muriatic acid(10% HCL), 0.5% Toluidine blue, forceps, scalpel, needle, toothpick, distilled water, dropper, gloves, microscope slides and coverslips, dissecting microscope and compound light microscope.

Method: 

• Place 3-4 toothpicks inside the onion and put it in a jar of water with the onion root side down. Wait for a few days for the roots to grow
• Once the roots have grown, remove the onion from the water and cut about 5mm off the tips of the roots using a scalpel.
• Put the root tip in a beaker and pour muriatic acid in it. Uses gloves and safety goggles. Allow the roots to soak in the acid for 20 mins
• Use forceps to remove the root tip from the acid and place it on a microscope slide. Using a dropper, put 3-4 drops of distilled water over it.
• Using a scalpel, trim the roots to 2mm and then using a needle slice it into 2 or more lengthwise sections.
• Using a dropper, put 2-3 drops of Toluidine blue and wait for 2 minutes. Put the coverslip on and soak excess dye using a paper towel.
• Observe the slide under a microscope, first at the lowest magnification and then at the highest.
• Once you’re able to identify the different stages of mitosis, draw them.
• Now, count the cells in each stage and record them using tick marks.
• Once you have counted at least 1000 cells, convert your tick marks to numbers. Graph your results with a bar graph.

Result: 

Analysis and Interpretation : (Prepare a pie chart and write your interpretation based on your result)

Conclusion: After DNA replication, onion cells go through different stages of mitosis.

Biology Projects for Class 12

The study of biology projects is very much important in order to understand various kinds of biological processes that occur within animals and even humans. Scientists make a clean study of nature and its contents( living or non-living) in order to learn the ways of improving animal health for the purpose of farm production, human companionship and also wildlife preservation. They even study animal life in order to discover various new methods to improve human health.

Animal studies provide a better understanding of disease development and also its prevention, along with the standards for knowing normal and abnormal behaviour. These project ideas introduce us to the areas of animal studies, which are explored through the process of experimentation. Scientific experiments consist of a number of steps that are followed by scientific investigators in order to answer questions about the natural world. It also involves making an observation, formulating a hypothesis, and conducting scientific experiments too. The scientific inquiry begins with the observation that is followed by formulating a question as to what is observed.

Here are some great ideas for Biology Projects for Class 12, which are related to plants, animals, and the human body.
