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.
