  1. Life Science Chapter Two

  2. TAKS Objective 2 – The student will demonstrate an understanding of living systems and the environment.

  3. Feedback Systems • Students will use multimedia segments to learn about how feedback systems regulate the body. • Students will perform a skit about glucose.

  4. You can’t have one without the other. There are twelve major organ systems in the human body (i.e., circulatory, skeletal, respiratory, excretory, integumentary, nervous, digestive, endocrine, reproductive, immune, lymphatic, and muscular systems). In this TEKS, we will introduce the most common interactions in the human body by relating them to the nervous and/or circulatory system.

  5. I’m depending on you In the lesson the student uses plastic soda bottles to build an ecocolumn which will be used to study biotic and abiotic interactions in terrestrial and acquatic systems (e.g., food chains, food webs, competition, chemical and nutrient cycling). The ecocolumn structure will be used to further understandings about how salt, fertilizer, and acid rain upset the balance of ecosystems (TEKS 8.14 C).

  6. Objective - The student will describe in the science journal at least seven environmental conditions that can have significant impact on the survival of individuals and species.

  7. ENGAGEDon’t Leap to Conclusions: The Case of the Malformed Frogs • Use the jigsawing teaching strategy where each group of students become experts on a particular topic. • After groups of students read the articles and answer the appropriate questions, allow then to share their information.

  8. Who’s da mama? Lesson Objectives • Students will apply their understanding of probability by making predictions. • Students will be able to complete monohybrid cross problems. • Students will apply their knowledge of Punnett squares to real-world situations. • Students will communicate information about genetic disorders by creating a brochure for publication.
