1. Close your mouth and close your nose with your fingers so that air cannot pass through it. Measure the time.

2. Hold a finger under the nose of one of your friends. What did you feel on your finger? Use this method to find out how many times your friend inhales and exhales in a minute.

3. Take a measuring tape. Wrap the tape around the chest of one of your friends and measure the width of her/his chest. Hold the tape lightly and ask your friend to breathe in and out deeply.

4. Fill a measuring cylinder to the brim and invert it in a bucket or a large container of water. Insert one end of a rubber tube into the mouth of the cylinder under water. Hold the other end of the tube in your hand. Inhale as much air as you can and blow the air into the measuring cylinder through the rubber tube. Blow out as much air as you can in a single breath.

5. Exhale air from your nose on the back of your index finger. Is this air warm?

6. Take a mirror. Wipe it clean with a cloth. Blow air from your mouth on the surface of the mirror. What did you observe?

Clean the mirror and blow air on it with a syringe. Observe.

7. Take two boiling tubes and insert two glass pipes in each of them. Fill both boiling tubes one fourth with phenolphthalein solution. Mark them A and B. Now repeatedly blow in and suck out air.

8 . 1. Take a conical flask. Fit a two-holed rubber cork tightly into its mouth and insert glass tubes into the two holes. Fit a rubber tube on one of the glass tubes and a funnel on the other.

2. Fill a test tube about one fourth with lime water and dip the rubber tube into it.

3. Add water till the conical flask is filled one fourth. Observe the test tube carefully.

4. Now remove the water from the conical flask and put some flowers and buds in it.

5. After 30 min, repeat Step 3.

Repeat the experiment by replacing flowers and buds with germinating seeds.
