               INVESTIGATORY PROJECTS

The syllabus of biology practicals at senior secondary levels also includes a project or investigatory experiment to develop the concept of original thinking, planning and performing scientific ideas. A student can plan his or her

own experiment and perform that to test the validity of the idea. Such experiments require several hours or days even. The syllabus of class XII has a list of such experiments. Out of which student can choose any one or he/she can plan a project of his/her own choice.

GUIDE LINES FOR PROJECT WORK

1.Selection of topic. For selection of the topic for the project work road different chapters of your syllabus and also consult scientific literature. Then select the topic of your interest.

2. Planning of the project. Collect all possibly available informations about the topic of the project. Prepare a rough outline of the experimental work of the project.

3. Experimentation for the project. Plan and conduct the experimental work with precision so that you are sure to get correct results.

Following points should be kept in mind while performing the experiments for the project work.

(i) Collect data with honesty and utmost care. Record only your observations and data.

(i) Repeat the experiment several times and take average of the results of all the experiments.

(iii) Compare your results with those available in the reference books.

(iv) Discuss your results in the light of available information about the project and draw out meaningful conclusion.

(v) Make use of histograms, graphs, photographs, diagrams or models to support your observations and conclusions.

(vi) Give a list of books, magazines or journals you have consulted during the course of your project.

(vi) Acknowledge the guidance, help and assistance rendered by your teacher, parents, neighbours and friends by expressing sincere gratitude and thanks to them in the beginning.

HOW TO WRITE A PROJECT/INVESTIGATORY EXPERIMENT

A student is required to do a project work, collect related data and write it. It is a type of experimental exercise performed with a scientific attitude. Students are required to get their project report typed on bond paper sheets (if possible) and to represent in the best possible manner. The project report should be written in the

following sequence:

1.Title/Aim-Name of the project.

2.Introduction-Information collected from various sources related to the topic.

३-Requirements-Materials required for experimental work.

4.Procedure- Write details of the experimental work you have performed.

५.Observations-Record your observations/data in the form of tables, histograms, graphs etc.

6. Results/Conclusion-Give analysis of the data and compare your results with those available in the literature and draw conclusions.

7.References Give the list of books, magazines or journals you have consulted, for the project work.
