Ans:- The food insecure people are disproportionately large in some regions of the country, such as economically backward states with high incidence of poverty, tribal and remote areas, regions more prone to natural disasters etc. a large section of people suffer from food and nutrition insecurity in India, the worst affected groups are landless people with little or no land to depend upon, traditional artisans, providers of traditional services, petty self-employed workers and destitute including beggars. In the urban areas, the food insecure families are those whose working members are generally employed in ill-paid occupations and casual labour market. These workers are largely engaged in seasonal activities and are paid very low wages that just ensure bare survival.

6. (Motivate) Angles in the same segment of a circle are equal.
7. (Motivate) If a line segment joining two points subtendes equal angle at two other points lying on thesame side of the line containing the segment, the four points lie on a circle.
8. (Motivate) The sum of the either pair of the opposite angles of a cyclic quadrilateral is 180o and itsconverse

7. CONSTRUCTIONS (10) Periods

1. Construction of bisectors of line segments & angles, 60o, 90o, 45o angles etc., equilateral triangles.
2. Construction of a triangle given its base, sum/difference of the other two sides and one base angle.
3. Construction of a triangle of given perimeter and base angles.

UNIT V : MENSURATION

1. AREAS (4) Periods

Area of a triangle using Hero's formula (without proof) and its application in finding the area of a quadrilateral.

2. SURFACE AREAS AND VOLUMES (10) Periods
Surface areas and volumes of cubes, cuboids, spheres (including hemispheres) and right circular cylinders/cones.

UNIT VI : STATISTICS AND PROBABILITY

1. STATISTICS (13) Periods

Introduction to Statistics : Collection of data, presentation of data - tabular form, ungrouped / grouped,bar graphs, histograms (with varying base lengths), frequency polygons, qualitative analysis of data to choosethe correct form of presentation for the collected data. Mean, median, mode of ungrouped data.

2. PROBABILITY (12) Periods
History, Repeated experiments and observed frequency approach to probability. Focus is on empirical  probability. (A large amount of time to be devoted to group and to individual activities to motivate the concept; the experiments to be drawn from real - life situations, and from examples used in the chapter on statistics).

PRACTICALS

LIST OF EXPERIMENTS

Marks : 40 (20 + 20)

1. To prepare

a) a true solution of common salt, sugar and alum
b) a suspension of soil, chalk powder and fine sand in water
c) a colloidal of starch in water and egg albumin in water and distinguish between these on the basis of

iv) Heating of Lead Nitrate

v) Sodium sulphate with Barium chloride in the form of their solutions in water.

4. To verify laws of reflection of sound.

5. To determine the density of solid (denser than water) by using a spring balance and a measuring cylinder.

6. To establish the relation between the loss in weight of a solid when fully immersed in

i) tap water

ii) strongly salty water, with the weight of water displaced by it by taking at least two different solids.

7. To measure the temperature of hot water as it cools and plot a temperature-time graph.

8. To determine the velocity of a pulse propagated through a stretched string/slinky.

9. To prepare stained temporary mounts of (a) onion peel and (b) human cheek cells and to record observations

and draw their labeled diagrams.

10. To identify parenchyma and sclerenchyma tissues in plants, striped muscle fibers and nerve cells in animals,

from prepared slides and to draw their labeled diagrams.

sublimation.

12. To determine the melting point of ice and the boiling point of water.

69

13. To test (a) the presence of starch in the given food sample (b) the presence of the adulterant metanil yellow in

dal.

14. To study the characteristic of spirogyra/Agaricus, Moss/Fern, Pinus ( either with male or female conre) and an

Angiospermic plant. Draw and give two identifying features of groups they belong to.

15. To observe and draw the given specimens-earthworm, cockroach, bony fish and bird. For each specimen

record

(a) one specific feature of its phylum

(b) one adaptive feature with reference to its habitat.
