Activities

[Author - Arshea Bimal]

1. Take a fresh potato. Observe the scars on it with the help of a magnifying glass. You may find bud(s) in them. These scars are also called “eyes”. Cut a few pieces of a potato, each with an eye and bury them in the soil. Water the pieces regularly for a few days and observe their progress. What do you find?(TEXTBOOK)

Lesson Plan version 1.1 activities

1. Cut a branch of rose or champa with a node. This piece of branch is termed a cutting. Bury the cutting in the soil. A node as shown in the figure is a part of the stem/branch at which a leaf arises. Water the cutting every day and observe its growth.

2. Take a fresh potato. Observe the scars on it with the help of a magnifying glass. You may find bud(s) in them. These scars are also called “eyes”. Cut the potato into small portions, each with an eye and bury them in the soil. Water the pieces regularly for a few days.

3. Take a piece of yeast cake or yeast powder from a bakery or a chemist shop. Take a pinch of yeast and place it in a container with some water. Add a spoonful of sugar and shake to dissolve it. Keep it in the warm part of a room. After an hour, put a drop of this liquid on a glass slide and observe under a microscope.

4. Take a mustard/china rose/petunia flower and separate its reproductive parts.
