Subject: Elementary Education Science 5905
Chapter: Life Science
Life science explores how living organisms are structured, how they function, how traits are inherited, and how species change over time. Teachers preparing for the Praxis 5905 Science Subtest must understand how cells, tissues, organs, and organ systems work together to sustain life. They must also understand heredity, evolution, regulation in living systems, and the classification of organisms. These concepts help explain both the unity and diversity of life on Earth.
By the end of this lesson, you should be able to:
- Explain how living systems are organized from cells to organ systems
- Describe how reproduction and heredity transmit traits between generations
- Explain how organisms change over time through evolution and natural selection
- Describe how living organisms regulate internal conditions and respond to stimuli
- Explain the unity and diversity of life and how organisms are classified
- Identify how adaptations help organisms survive in different environments
