Some of the Human Body Parts:

1. Brain: The brain controls all body functions, including movement, sensation, and thought. It is like the control center of our body.

2. Heart: The heart pumps blood throughout the body to deliver oxygen and nutrients to the cells. It beats all day and all night to keep us alive.

3. Lungs: The lungs take in oxygen from the air and remove carbon dioxide from the body. We have two lungs in our chest.

4. Stomach: The stomach breaks down food into smaller pieces so that it can be digested. It is like a food processing machine in our body.

5. Liver: The liver produces bile to help digest fats. It also cleans the blood and stores energy.

6. Kidneys: The kidneys filter waste products from the blood and produce urine. We have two kidneys in our body.

7. Bones: Bones provide support for the body, protect vital organs, and produce blood cells. Our skeleton is made of many bones.

What is Soil?

Soil is the loose material that covers the ground. It is made up of tiny pieces of rocks, minerals, decayed plants and animals, and other natural materials. Soil is very important because it helps plants grow.

Loamy Soil:

Loamy soil is a well-balanced soil type that consists of a mixture of sand, silt, and clay. It has a crumbly texture, which makes it easy to work with.

Characteristics of Loamy Soil:

• It feels soft and crumbly when you touch it
• It is generally rich in nutrients
• It can hold water well
• It can support the growth of a wide variety of plants
• It is considered to be one of the best soil types for gardening and farming

Sandy Soil:

Sandy soil is a soil type that is primarily composed of sand particles. It has a gritty texture and a loose structure.

Characteristics of Sandy Soil:

• It feels rough and gritty when you touch it
• It cannot hold water well and can quickly become dry
• This makes it difficult for plants to grow in
• Sandy soil is also low in nutrients
• It often requires the addition of fertilizers to support plant growth

EVALUATION:

1. Explain Sandy soil and Loamy soil.

What is Water?

Water is a transparent, odorless, and tasteless liquid that is essential for life on Earth. It is a universal solvent. This means it can dissolve many substances.

Sources of Water:

There are several sources of water, including:

1. Surface Water: This includes water found in rivers, lakes, and reservoirs. These are bodies of water we can see on the surface of the Earth.

2. Groundwater: This is water that is stored underground in porous rocks, soil, and underground rivers. We get this water through wells and boreholes.

3. Rainwater: This is water that falls from the sky in the form of rain, snow, and hail. Rainwater is fresh and clean.

4. Ocean Water: The world’s oceans contain about 97% of the Earth’s water. However, ocean water is salty and needs to be treated before we can drink it.

5. Wastewater: This is water that has been used and discarded, such as sewage and industrial wastewater. This water can be treated and reused.

EVALUATION:

To help pupils understand the sources of water, teacher should conduct a simple experiment:

Pupils should take a large bowl and place it outside overnight. In the morning, pupils will observe that the bowl has collected dew, which is a form of condensed water vapor from the atmosphere. Teacher should explain that this is another source of water, albeit a minor one, and can discuss other sources of water in the environment.
