Ohio Science Academic Content Standards (2002)
Analyze plant and animal structures and functions needed for survival and describe the flow of energy through a system that all organisms use to survive.
Compare changes in an organism's ecosystem/habitat that affect its survival.
Explain how energy entering the ecosystems as sunlight supports the life of organisms through photosynthesis and the transfer of energy through the interactions of organisms and the environment.
Grade Level Indicators (Grade 3)
Describe how changes in an organism's habitat are sometimes beneficial and sometimes harmful.
Grade Level Indicators (Grade 5)
Trace the organization of simple food chains and food webs (e.g., producers, herbivores, carnivores, omnivores and decomposers).
Grade Level Indicators (Grade 7)
Explain how the number of organisms an ecosystem can support depends on adequate biotic (living) resources (e.g., plants, animals) and abiotic (non-living) resources (e.g., light, water, soil).
Scientific Ways of Knowing
Use skills of scientific inquiry processes (e.g., hypothesis, record keeping, description, explanation).
Grade Level Indicators (Grade 8)
Identify the difference between description (e.g., observation and summary) and explanation (e.g., inference, prediction, significance, importance).
