Science

Life Science

Power Standards
  • Use argument supported by evidence for how the body is a system of interacting subsystems composed of groups of cells. (Organization of the body, and interaction of body systems)  (MS-LS1-3)
  • Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories. (MS-LS1-8)

Critical Content

Concepts and Skills

* Power Standard Content

LS1.A:  Structure and Function (Human Body Systems intro)

  • In multicellular organisms, the body is a system of multiple interacting subsystems. These subsystems are groups of cells that work together to form tissues and organs that are specialized for particular body functions. (MS-LS1-3)

LS1.B:  Growth and Development of Organisms (Reproductive System)

  • Animals engage in characteristic behaviors that increase the odds of reproduction. (MS-LS1-4)

LS1.C:  Organization for Matter and Energy Flow in Organisms (Digestive System)

  • Within individual organisms, food moves through a series of chemical reactions in which it is broken down and rearranged to form new molecules, support growth, or release energy. (MS-LS1-7)

LS1.D:  Information Processing (Nervous System)

  • Gather and synthesize information that sensory receptors respond to stimuli by sending messages to the brain for immediate behavior or storage as memories.
  • Each sense receptor responds to different inputs (electromagnetic, mechanical, chemical), transmitting them as signals that travel along nerve cells to the brain. The signals are then processed in the brain, resulting in immediate behaviors or memories. (MS-LS1-8)

PS3.D:  Energy in Chemical Processes and Everyday Life (Respiratory System)

  • Cellular respiration in plants and animals involves chemical reactions with oxygen that release stored energy.  In these processes, complex molecules containing carbon react with oxygen to produce carbon dioxide and other materials.

Critical Language (Science & Engineering Practices)

Language Usage

  • A student in eighth grade can demonstrate the ability to apply and comprehend critical language by explaining a model of cells and their function in how body systems are organized.

Concept-Based Connections

Essential Understandings

  • Living organisms are made out of cells and special structures are responsible for particular functions in organisms.
  • The body is a system of multiple interacting subsystems that form a hierarchy from cells to the body.
  • The systems in the body all work interdependently in order for the body to properly function.
  • The daily decisions we make impact our body systems and overall health in positive or negative ways.

 

Factual Guiding Questions

  • What are the components of the system?
  • What are the functions of the components?
  • What is the function of the system?
  • How do choices positively impact this system?
  • How do choices negatively impact this system?
  • How do the systems work interdependently with one another?
  • How do plants, animals, and humans increase or decrease their odds of reproduction with the behaviors/choices they make?

 

Conceptual Guiding Questions

  • How do structures of organisms contribute to life’s functions and overall health?
  • What happens to the body and its systems when one system isn’t functioning properly?
  • How is energy distributed through the body?
  • How does the body use the sensory information to cause a behavioral response or a memory?

 

Authentic Learning Activities & Experimental Design

  • How can teens make healthier choices? (Tobacco, Alcohol, Drugs, STDs, Teen Pregnancy, Sleep, Nutrition, Exercise, Stress)
  • How does the interdependence of body systems affect a species’ ability to survive?
