7th Grade Science Unit 10

Big Idea:

The human body is composed of multiple, complex systems which perform specific tasks to ensure survival.

Student Expectations:

Priority TEKS

7.12(B) [Supporting] 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.

Focus TEKS

7.3(B) [Ways to Show] use models to represent aspects of the natural world such as human body systems and plant and animal cells.

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

7.12(C) [Supporting] recognize levels of organization in plants and animals, including cells, tissues, organs, organ systems, and organisms.

7.12(E) [Supporting] compare the functions of cell organelles to the functions of organ systems

Ongoing TEKS

7.1(A) [Tools To Know] Demonstrate safe practices during laboratory and field investigations

7.1(B) [Tools to Know] Practice appropriate use and conservation of resources, including disposal, reuse, or recycling of materials.

7.2(A) [Tools To Know] The student is expected to plan and implement comparative and descriptive investigations by making observations, asking well defined questions, and using appropriate equipment and technology.

7.2(E) [Ways to Show] analyze data to formulate reasonable explanations, communicate valid conclusions supported by the data, and predict trends.

7.4(A) [Tools To Know] use appropriate tools to collect, record, and analyze information, including life science models, hand lens, stereoscopes, microscopes, beakers, Petri dishes, microscope slides, graduated cylinders, test tubes, meter sticks, metric rulers, metric tape measures, timing devices, hot plates, balances, thermometers, calculators, water test kits, computers, temperature and pH probes, collecting nets, insect traps, globes, digital cameras, journals/notebooks, and other

7.4(B) [Tools To Know] use preventative safety equipment, including chemical splash goggles, aprons, and gloves, and be prepared to use emergency safety equipment, including an eye/face wash, a fire blanket, and a fire extinguisher.

Student Learning Targets:

• I will be able to identify the functions of organ systems.
• I will identify the functions of organs in a particular organ system.
• I will write about how body systems work together and are essential for ensuring the survival of living organisms.

Essential Questions:

• How does food get broken down and used by the body?
• How does the body get rid of wastes?
• Why are the respiratory and circulatory systems important for survival?
• How does the body move?
• How does the body respond to environmental changes?
• How does the body protect itself?
• How does the endocrine system help in human reproduction and development?
