BASIC SCIENCE

BASIC SCIENCE AND TECHNOLOGY 

SMASE – ASEI PDSI METHOD

FIRST TERM

WEEK 6

PRIMARY 5

TOPIC – EROSION 

 

LEARNING AREA 

  • Lesson One – Effects of Erosion
  • Lesson Two – Controlling Soil Erosion
  • Lesson Three – Revision and Test

 

TIME – 40 Minutes each.

 

LEARNING OUTCOME 

By the end of the lesson, pupils should be able to –

  1. list the effects or dangers of erosion
  2. identify, discuss and implement simple strategies for controlling erosion.

 

 

RATIONALE

We experience erosion around us. Erosion can have a number of causes, but the effects are usually the same. The most visually noticeable effect is soil damage. Topsoil is very valuable, because it is nutrient-rich and feeds both seeds and plants. The flow of wind or water can remove topsoil leading to the loss of the nutrients and resources. This makes the soil poor and the crops will not grow well.

Erosion also makes land unusable and in severe cases, it can cause buildings to collapse. During erosion, soil and sediments can also be washed into rivers and streams, clogging up the habitats of animals that live in the rivers and streams or nearby.

 

LEARNING MATERIALS 

The teacher will teach the lesson with the aid of:

  1. Buckets of water, hand fans. soil and trays (per groups).
  2. Pictures or charts showing erosion.Pictures/posters of large piece of land, flashcards with the following statements: “crops will grow”, “crops will not grow”, “the soil is good”, “the soil is bad”, “land is good for building”, and “buildings cannot be built on the land”.

 

PREVIOUS KNOWLEDGE

Rainfall is the main causes of running water and strong wind comes along with different particles especially soil. The pupils understand these concepts.
