REVISION 3 – CHANGES IN PLANTS 

Plants grow when seeds or young plants are put in the ground to grow.

As the plant grows, changes such increase in height, width and the number of leaves take place.

Putting seeds in the ground to grow are not strange to the pupils.

The change in plants as they grow is called life cycle.

The plant life cycle consists of four stages; seed, sprout, small plant, and adult plant.

REVISION 4 – CHANGES IN ANIMALS 

The animal kingdom is full of variety.

All living things share certain characteristics. This is how you know that something is living or not living. Living things do what non-living things cannot do on their own.

They,

• Move

• Respire (breathe)

• Excrete

• Grow

• Eat

• Respond to change

Young animals are produced by reproduction. Most have a nervous system and can move of their own accord. From birth, each individual grows, becomes an adult and often produces young.

It is called a life cycle.

REVISION 5 – CHANGES IN HUMAN 

Humans grow and mature in order to complete their life cycles.

So too do other animals. For us, growth involves physical and emotional changes and also changes to the thinking power of the brain. Babies have changed by age 2 to children, then at age about 11 to adolescent and then around 18 to mature adult.
