Tutor Marked Assignments

Important Instructions for 2016-2017 Dear Learner,

By now you must have started studying your Higher Secondary Course of the

Assam State Open School [ASOS] under the Assam Higher Secondary Education Council

[AHSEC]. As you already know, planned and continuous study is necessary for successful

completion of a course. We have developed several means and strategies to help you to

learn and be a successful learner. Tutor Marked Assignments (TMA) is one of such

means.

TMAs will help you to : develop regular study habit which is necessary to become a self learner;

know the subject matter better;

get practice in writing responses to questions thereby having a kind of rehearsal in

the preparation for the final examination;

receive feedback and confirmation about the correctness of the response provided by

you;

check your progress in studying the subject you had opted for, so that you can find

out subject areas where you have difficulties and need to put in more effort to learn well;

and

maintain contact with the subject teachers at the Accredited Institution (AI) in which

you are registered and enable you to take appropriate guidance in your studies.

There are three assignments in each subject. You are required to complete the

assignments in your own handwriting in the chosen subjects only and submit them to your Coordinator at your Accredited Study Centre.

We have tried to give you some practice in two types of questions that are usually set in your term end question papers.

The schedule for submission of the TMA is as given below:

The awards of the TMAs at Senior Secondary Courses will be in grades and the grades of the assignments submitted by you will be reflected in the mark-sheet.

Do not forget to take a receipt of submission of your TMA from your teacher.

For every academic year a new set of TMA booklets will be available at the Study Centres. Go through the corrected assignments carefully and use them to improve your performance by:

re-reading the lessons in the study materials provided to you by ASOS;

attending PCP classes to clarify doubts from the teacher or solve problems that you face during studies; and

devoting more time for studies. Looking into the benefits of TMA, it will be possible for you to make best use of it in order to become a successful learner. If you have any doubt or suggestions, please do not hesitate to write to us. We wish you all the best. PLEASE NOTE THAT SUBMISSION OF TMA OF THE SUBJECTS APPLIED FOR IS COMPULSORY.

are easy to culture,have a short generation time and are prolific breeders. You may get your own

culture of fruit flies by just taking a ripe banana and an empty well cleaned jam bottle. Keep the

banana in the bottle and place it at a fruit or

vegetable vendor‟s cart or shop. You will find red eyed fruit flies entering the bottle. Cover with a

soft cloth and tie the cloth at the month of the bottle with a rubber band after some flies have entered

the bottle.

Keep the bottle near the window sil for two days. They would have mated and laid eggs.

After one or two days tiny growing larvae will hatch from eggs. After another fews days well grown

larvae will become pupae and then fruit flies will hatch from them. Now invert another empty jam

bottle on the Drosophila bottle. Fruit flies will fly up into the empty bottle. Release them. Now

study the life cycle by observing the happenings in the covered bottle with the banana.

Record the following

1. Date of collection of flies and day.

2. Date of tiny larvae to come out. The first larvae are tiny and called first

instar larvae.

3. Observe them eating and getting fatter and note the duration of larval stage.

4. Note the number of days they take to pupate. Pupae are oval, small, egg shaped bodies

sticking to drier

parts of the inside walls of the bottle. Note the number of days taken for the flies to hatch

from the pupae.

Project 4 Constructing a green house from scrap material

i. You are learning a lot about the „greenhouse effect‟ and global warming. Why not

see for yourself how sun rays heat the greenhouse and keep it warm enough for

plants to survive in it.

ii. You shall need some pieces of glass or transparent plastic sheets, Brown cello tape,

cardboard, plastic pipes to circulate water inside the chamber, table fan to cool the

inside.

iii. Now see the figure 35.9 of green house on page 48 of module 6A of your senior

secondary Biology book 3.
