Lesson Plan version 1.1 acitivites

1.Bring a packet of food grain to the classroom. Now, spread the grains on a sheet of paper. You may find pieces of stone, husks, broken grain and particles of other grains in it. Now, remove with your hand these unwanted pieces of stone, husks and other grains from it.

2. Make a mixture of dry sand with sawdust or powdered dry leaves. Keep this mixture on a plate or a newspaper.

Hold the plate or the sheet of paper containing the mixture, at your shoulder height. Tilt it slightly, so that the mixture slides out slowly.

3. Bring a sieve and a small quantity of flour from home, to the class. Sieve the flour to separate any impurities in it.

4. a. Collect some muddy water from a pond or a river. Let it stand for half an hour. Observe the water carefully and note your observations.

b. Now, slightly tilt the glass without disturbing the water. Let the water from the top flow into another glass.

c. Now filter it using a piece of cloth.

5. Take a mixture of sand and salt. Keep this mixture in a beaker and add some water to it. Leave the beaker aside for some time. The sand can be separated by decantation or filtration.

Transfer this liquid to a kettle and close its lid. Heat the kettle for some time. Take a metal plate with some ice on it. Hold the plate just above the spout of the kettle. What do you observe?

6. Pour half a cup of water in the beaker. Add one teaspoonful of salt and stir it well, until the salt dissolves completely. Again add a teaspoonful of salt and stir well. Go on adding salt, one teaspoonful at a time, and stir.

7. Make a saturated solution of salt in water. Add a small quantity of salt to this saturated solution and heat it. Let this hot solution cool. Observe carefully.

8. Take two glasses and pour half a cup of water in each of them. Add a teaspoon of salt to one glass and stir till the salt dissolves. Go on adding salt, one teaspoon at a time, till the solution saturates.
