Standards of Learning

Grade Two
Life Processes

2.4 The student will investigate and understand that plants and animals undergo a series of orderly changes in their life cycles. Key concepts include

a) some animals (frogs and butterflies) undergo distinct stages during their lives, while others generally resemble their parents; and
b) flowering plants undergo many changes, from the formation of the flower to the development of the fruit.

Overview
The concepts developed in this standard include the following:
• Throughout their lives, plants and animals undergo a series of orderly and identifiable changes.
• Changes in living things over time occur in cycles and differ among the various plants and animals.
• Some animals, such as frogs and butterflies, go through distinct stages as they mature to adults. Other animals, such as deer, resemble their parents from birth to maturity and do not have distinct stages.
• An important part of the life cycle of a flowering plant is the formation of the flower to the development of the fruit.
