• The work plan includes routines, review, activity, discussion, IXL activity, and wrap-up.
• Plants and animals differ from one another.

Science Trivia

Life Cycle

• The stages of growth and change make up an organism's life cycle.
• All living things follow a pattern of birth, growth, reproduction, and death.

Stages in Human Life Cycle

• All humans go through a series of changes as they grow
• Before a baby is born, it develops inside the mother's body for about nine months.

Infants

• Adulthood represents the mature stage of human development.
• As an adult, you will need to provide food for yourself.
• Reading books and learning new skills help to keep your mind active throughout your adulthood.
