Duration:- 40 minutes

Date:- 6th ,May 2020

Behavioural Objectives:-

At the end of the lesson the students should be able to:-
1. Draw a food chain representing grassland habitat.
2. List and write on three(3) factors that effects grassland habitat.

Instructional Material(s):-

A chart showing the food chain in grassland habitat.

Introduction:-

Presentation

Step 1:- Food chain in a grassland habitat.

The savanna is also a community where there are several food chains. Example of food chains In the grassland habitat include:-
1. Grass--> Grasshoppers-->Lizards-->Snakes.
2. Grass-->Zebras-->Lions
3. Grass-->Grasshoppers-->Toads-->Birds.

Step 2:- Factors Affecting Grassland Habitat.

1. Light Intensity:-
Light intensity is very high since there is little vegetation to shield its rays. Also photosynthetic activities are high in this habitat.

2. High Temperature:-
The grassland is affected by extremes of temperatures which range from 21-30degree celcius. The annual temperature range is 11 degree celcius.

3. Moderate rainfall:-
The grassland has an annual rainfall of about 600-1500m. It has seasonal conventional rainfall with single maximum.

4. Fertile Soil:-
Soil in grassland is always Bert fertile as most of the nutrients are not leached or eroded because of low rainfall.

Evaluation:-

The teacher ask the students question to ascertain the level of their understanding:-

1. Draw a food chain representing grassland habitat.
2. List and write on three(3) factors that effects grassland habitat.

Homework:-

1. List two factors affecting grassland habitat
2. Draw a food chain representing grassland habitat.
