1) An experiment was
conducted to show that stem conducts water to all parts of the plant. A white
flower was placed on a bottle which was partially filled with red water.
Gradually this white flower developed a pinkish tinge which shows that the
stem transports water to different parts of the plant.
2) Two potted plants,
(green gram) planted on the same day, in similar pots. They were labeled as Pot
A and Pot B. One pot was placed in the sunlight and the other pot was placed in
the dark. After a few days it was noticed that the pot which was kept in
sunlight, had grown and the leaves were green in colour. Whereas the pot which
was kept in the dark, had yellow leaves. This proves that sunlight is
required for photosynthesis. The pot which was kept in dark could not prepare
its food so the leaves turned yellow. The children understood the importance of
photosynthesis and noticed the difference between the two potted plants.
