Objectives:-• Observe the rate of growth of seeds• Recognize what do plants need to grow• Differentiate between different seeds of

different plants• Describe the life cycle of the plants• Describe the life cycles of the some animals• Differentiate between the complete and

incomplete metamorphoses.• Differentiate between animals and plants life

What do living things need to grow?All living things grow and change.All living things need food, water, and air to

live.

Animal life cyclesAnimals grow and change during their life

span, or from time to birth up to death.The series of changes in appearance it called

metamorphosis. Example of some animals life cycles Butterfly life cycle Frog life cycle
