Colorado: Science [1995]
Standard 3: Life Science: Students know and understand the characteristics and structure of living things, the processes of life, and how living things interact with each other and their environment. (Focus: Biology--Anatomy, Physiology, Botany, Zoology, Ecology) (Grades K - 12)
Currrent Standard
• 3.2 Students know and understand interrelationships of matter and energy in living systems. (Grades K - 12)
Standard's Subset
In grades K-4, what students know and are able to do includes recognizing that green plants need energy from sunlight and various raw materials to live, and animals consume plants and other organisms to live; and (Grades K - 4)
In grades K-4, what students know and are able to do includes recognizing the interrelationships of organisms by tracing the flow of matter and energy in a food chain. (Grades K - 4)
As students in grades 5-8 extend their knowledge, what they know and are able to do includes comparing and contrasting food webs within and between different ecosystems (for
example, grasslands, tundra, marine) and predicting the consequences of disrupting one of the organisms in a food web; (Grades 5 - 8)
As students in grades 5-8 extend their knowledge, what they know and are able to do includes describing the basic processes of photosynthesis and respiration and their importance to life (for example, set up a terrarium or aquarium and make changes such as blocking out light); (Grades 5 - 8)
As students in grades 5-8 extend their knowledge, what they know and are able to do includes describing ways (for example, digestion, transport of nutrients by circulatory system) that multicellular organisms get food and other matter to their cells; (Grades 5 - 8)
As students in grades 5-8 extend their knowledge, what they know and are able to do includes explaining the recycling of materials by determining a pathway of a substance that is important for life (for example, trace water through an ecosystem); and (Grades 5 - 8)
As students in grades 5-8 extend their knowledge, what they know and are able to do includes<ul><li>describing the role of organisms in the decomposition and recycling of dead organisms (for example, bacteria’s role in the decomposition and recycling of matter from a dead animal).</li></ul> (Grades 5 - 8)
As students in grades 9-12 extend their knowledge, what they know and are able to do includes comparing and contrasting the processes of photosynthesis and respiration (for example, in terms of energy and products); (Grades 9 - 12)
As students in grades 9-12 extend their knowledge, what they know and are able to do includes describing the cycling of matter and the movement and change of energy through the ecosystem (for example, some energy dissipates as heat as it is transferred through a food web). (Grades 9 - 12)
As students in grades 9-12 extend their knowledge, what they know and are able to do includes explaining how energy is used in the maintenance, repair, growth, and development of tissues (for example, in the production of new skin cells requires energy); and (Grades 9 - 12)
As students in grades 9-12 extend their knowledge, what they know and are able to do includes explaining how large molecules (for example, starch, protein) are broken down into smaller molecules, serving as an energy source or as basic building blocks in organisms; (Grades 9 - 12)
As students in grades 9-12 extend their knowledge, what they know and are able to do includes explaining how simple molecules can be built into larger molecules within organisms (for example, amino acids serve as building blocks of proteins; carbon dioxide and water are the basic materials for building sugars through photosynthesis); (Grades 9 - 12)
