Activities

[Contributor - Kripa S]

1. Ask students to name plants:

a) Smaller than them

b) Same size as them

c) Taller than them

2. Ask students to get a leaf to class. Illustrate their different parts. Show the different types of venation.

3. We would require seeds of gram and maize, cotton wool, katori and some water. Take two katoris. Place some wet cotton wool in them. Put 3 or 4 seeds of gram in one and maize in the other. Keep the cotton wet by sprinkling water every day, until the sprouts have grown into young plants. After a week try to separate the young plants from the cotton wool. (cotton wool can be replaced with soil) Help the students observe the roots of the gram seeds.

[Contributor - Mahika Joshi]

1. Pick out a plant to show all its parts such as the roots, stem, leaves, flowers etc. This will help the students refresh their previous knowledge.

2. Keep a moistened ball of crumpled paper in a conical flask. Place some soaked gram/beans in the flask between the paper and the glass wall. Observe and note the changes in the seeds in two or three days.

3. Take a glass jar and fill three quarters of it with water. Place an onion on the mouth of the jar in such a way that its roots are towards the water. Observe the growth for 8 days. Thread or Fiber like roots arising from stem are called fibrous roots.
