Science
Develop an understanding of how science explains changes in life forms over time, including genetics, heredity, the process of natural selection, and biological evolution.
Water on Earth is distributed and circulated through oceans, glaciers, rivers, ground water, and the atmosphere. Students can:
Identify the various causes and effects of water pollution in local and world water distributions
The student demonstrates an understanding of the structure, function, behavior, development, life cycles, and diversity of living organisms by identifying basic behaviors (e.g., migration, communication, hibernation) used by organisms to meet the requirements of life.
Craft and Structure
Determine the meaning of symbols, key terms, and other domain-specific words and phrases as they are used in a specific scientific or technical context relevant to grades 6-8 texts and topics.
Know and apply concepts that explain how living things function, adapt and change.
Compare and contrast how different forms and structures reflect different functions (e.g., similarities and differences among animals that fly, walk or swim; structures of plant cells and animal cells).
Develop an understanding that the advancement of scientific knowledge embraces innovation and requires empirical evidence, repeatable investigations, logical arguments, and critical review in striving for the best possible explanations of the natural world.
The student demonstrates an understanding of how energy can be transformed, transferred, and conserved by recognizing that energy can exist in many forms (i.e., heat, light, chemical, electrical, mechanical).
Identify common parts of plant and animal cells, including the nucleus, cytoplasm, and cell membrane.
Comparing unicellular and multicellular organisms
Identify major body systems and their functions, including the circulatory system, respiratory system, excretory system, and reproductive system.
All organisms have structures and systems with separate functions. Students can:
Develop and communicate an evidence-based scientific explanation of the role of different organs or structures that are important for an organism's survival - in both plants and animals
Describe the relationship of populations within a habitat to various communities and ecosystems.
Describing the relationship between food chains and food webs
Regulation and Behavior
Enduring Understanding: Organisms respond to internal and external cues, which allow them to survive.
An organism displays behaviors in response to internal cues, such as hunger, and external cues, such as light, temperature, or interaction with living things. (Level: Essential)
Reproduction, Heredity and Development
Enduring Understanding: Organisms reproduce, develop, have predictable life cycles, and pass on heritable traits to their offspring.
Most plants go through a life cycle of germination, growth, development, reproduction, and death. (Level: Essential)
Describe forms of energy, including chemical, heat, light, and mechanical.
Identifying types of potential and kinetic energy. Examples: potential - water behind a dam, battery; kinetic - water moving across turbine blades
The student demonstrates an understanding of the structure, function, behavior, development, life cycles, and diversity of living organisms by explaining how external features and internal systems (i.e., respiratory, excretory, skeletal, circulatory, and digestive) of plants and animals may help them grow, survive, and reproduce.
Elements and their combinations account for all the varied types of matter in the world. As a basis for understanding this concept:
Students know the common properties of salts, such as sodium chloride (NaCl).
The student demonstrates understanding of the interactions between matter and energy and the effects of these interactions on systems by identifying physical and chemical changes based on observable characteristics (e.g., tearing paper vs. burning paper).
The student demonstrates understanding of the structure and properties of matter by comparing models that represent matter as solids, liquids, or gases and the changes from one state to another. (L)
Describe the relationship of populations within a habitat to various communities and ecosystems.
Describing symbiotic relationships
Identify major body systems and their functions, including the circulatory system, respiratory system, excretory system, and reproductive system.
