Grade 7 Unit 02: Body Systems and Homeostasis (22 days)


TEKS

(7)  Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy. The student is expected to:

(B)  demonstrate and illustrate forces that affect motion in organisms such as emergence of seedlings, turgor pressure, geotropism, and circulation of blood.

(12)  Organisms and environments. The student knows that living systems at all levels of organization demonstrate the complementary nature of structure and function. The student is expected to:

(B)  identify the main functions of the systems of the human organism, including the circulatory, respiratory, skeletal, muscular, digestive, excretory, reproductive, integumentary, nervous, and endocrine systems;

(C)  recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms;

(E)  compare the functions of cell organelles to the functions of an organ system; and

(13)  Organisms and environments. The student knows that a living organism must be able to maintain balance in stable internal conditions in response to external and internal stimuli. The student is expected to:

(A)  investigate how organisms respond to external stimuli found in the environment such as phototropism and fight or flight; and

(B)  describe and relate responses in organisms that may result from internal stimuli such as wilting in plants and fever or vomiting in animals that allow them to maintain balance.
