Classification is a tool that humans use to give sense and order to the world. 

Classification

·         Classify organisms into kingdoms based on their macroscopic and cell structure and be familiar with organisms from each kingdom.

·         Apply classification skills to build a dichotomous key.

 

Living things are made up of cells and share common characteristics and requirements. 

Cells

·         Identify the functions of life carried out by cells and compare and contrast plant and animal cells, including major structure and function of organelles (cell membrane, cell wall, nucleus, cytoplasm, chloroplasts, mitochondria, vacuoles.) Explain how cells transfer energy through respiration and photosynthesis.

Demonstrate proper care and use of microscopes: cheek cell, elodea, onion skin.

The human body is organized into systems which interact to sustain life.

Energy in the Human body

·         Describe the hierarchical organization of the body: cells to tissues to organs to systems to organisms

·         Identify the specific structures and functions of human digestive, circulatory, and respiratory systems and model/describe how these systems interact.  Identify the general structures and functions of the other systems.

Genetic information is passed from one generation to the next and can create variation and similarity in offspring.

Reproduction and Heredity

·         Compare sexual and asexual reproduction.

·         Recognize that every organism needs a set of instructions (genes on chromosomes) to determine its traits and model how this information is passed from parent to offspring.

·         Give examples of adaptations and describe how these traits help an organism to survive and understand that adaptations arise from genetic mutations.

Over time, populations of organisms can adapt to their changing environment through natural selection.

Evolution

·         Give examples of how genetic variations and environmental factors are causes of natural selection.

·        Understand that evolution accounts for the diversity of species developed through a gradual process over many generations. Relate the extinction of species to a mismatch of adaptation and the environment.

·        Recognize that evidence drawn from geology, fossils, and comparative anatomy provides the basis of the theory of evolution.

 

 

Organisms are interdependent and changes in ecosystems impact which organisms survive.

Ecology

·         Describe how abiotic factors and the carbon and water cycles are important to a functioning ecosystem. 

·         Explain the roles and relationships among producers, consumers and decomposers in the process of energy transfer in an ecosystem.

·         Identify ways in which ecosystems have changed throughout geologic time in response to physical conditions, interactions among organisms, and the actions of humans.
