Activities

Lesson Plan version 1.1 activities

1. Let us take an empty glass bottle. Let us do the following activity to find what is there inside an empty glass bottle. Dip the open mouth of the bottle intothe trough filled with water. Observe the bottle. Does water enter the bottle?

Now tilt the bottle slightly. Now again dip the open mouth of the bottle. Do you think that water will enter the bottle?

When you perform the experiment, can you hear the bubbly sound? can you now guess what was inside the bottle?

The bottle was not empty at all. In fact, it was filled completely with air.

2. Take a healthy branch of Hydrilla and place it in a funnel. Invert the funnel in a beaker of water as shown in the figure. Invert a test tube over the stem of the funnel. The stem of the funnel should be kept immersed inside the water. Leave the beaker in sunlight for some time. You will notice some bubbles rising in the test tube. The bubbles contain oxygen released by the plant during photosynthesis. If we show a glowing splinter to the collected air, it burns brightly. This shows that the collected gas is oxygen.

3. Take a small portion of iron wool, press it into a 20 ml graduated test tube and wet it with water. Tip away excess of water. Take a 500ml beaker and fill half of the beaker with water. Invert the test tube and place it in air. Leave the arrangement at least for a week without making any disturbance to the test tube.

4. Place two candles on a table. Ensure that both the candles are of same size and height. Mark them as candle 1 and candle 2 using a chalkpiece. Light both the candles. Now, cover candle 2 with glass tumbler as shown in the figure Observe the happenings at both the candles.
