The 4 Big Ideas!1) The process of evolution drives the diversity and unity of life2) Biological systems utilize free energy and molecular building blocks to grow, to reproduce, and to maintain dynamic homeostasis3) Living systems store, retrieve, transmit, and respond to information essential to life processes4) Biological systems interact, and these

systems and their interactions possess complex properties

Big Idea 1:Evolution drives Diversity Use data and Hardy-Weinberg equations to

explain changes to a population over time Use data to explain natural selection Use data and Hardy-Weinberg equations to

predict changes in a population Connect evolutionary changes to changes

in an environment Use data and Hardy-Weinberg equations to

analyze genetic drift Predict effects of genetic drift, migration,

and artificial selection on a population Use multiple sources to support theory of

evolution Design experiments to test/observe

evolution

Big Idea 1:Evolution drives Diversity Design simulations that will show evolution Identify core processes for the history of life Explain specific examples of features shared

within each domain of life Explain if a proposed connection between

two species is correct Understand and use phylogenetic trees and

cladograms to show connections between species and their evolutionary history

Create cladogram or tree showing connections

Design experiments to test speciation and extinction

Explain speciation through isolation methods, gene frequency, environment, genetic drift, and Natural Selection

Big Idea 1:Evolution drives Diversity Describe hypothesis on origin of life Explain reasons to revise an hypothesis on

the origin of life Use geological, physical, and chemical data

to explain conditions of early Earth

Big Idea 2:Growth and Homeostasis

Explain how living things use free energy to grow and reproduce

Explain how sources of energy affect population and ecosystems

Explain mechanisms used by organisms to capture, store, and use free energy

Use surface area-to-volume ratios to predict stability of a cell

Explain why organisms use certain molecules to build while others are waste products

Able to explain data through a graph of the interaction between organism and the resources taken in to maintain homeostasis and grow

Explain properties of cell membranes and their function


Explain how active transport is necessary for homeostasis

Explain organelle structure and function Explain differences between prokaryotes and

eukaryotes Explain negative feedback regulation and how

changes to it affect a cell and system Explain how a cell uses negative feedback to

regulate an activity Explain positive feedback regulation and its

affects Use data to explain how a cell/organisms is

changing to its external environment Explain how biotic/abiotic factors will effect a

cell/system/population/community/ecosystem


Design an experiment for collecting data on how biotic/abiotic factors effect life at different levels

Explain how homeostasis is connected to evolution and homeostatic mechanisms can show common ancestry

Explain affects of disrupting homeostasis Explain the human immune system Explain the nonspecific immune system in

plants and animals (Not covered in class, you can read on your own; 35.1, 35. 2, 43.5)

Explain how timing and regulation of important events in development lead to a stable complex organism

Explain how apoptosis, differentiation, reuse of molecules, and homeostasis all play roles in early development


Explain connections between environments and physiological cycles in living things

Explain connections between environments and behavior of living things

Big Idea 3:Storing and Responding to Information

Explain structure of DNA and RNA Explain why we know DNA is hereditary

molecule Explain DNA replication, Mitosis and Meiosis,

Cell cycle Explain Protein synthesis: Transcription and

Translation Explain genetic engineering methods Explain mutations and how changes in

DNA/RNA effect protein structure Explain sources of genetic variation in

inheritance Explain common inheritance patterns and

Mendelian genetics with both vocabulary and mathematics

Explain ethical and social issues around genetic diseases

Explain non-Mendelian genetic patterns


Explain connection between gene expression and phenotype

Explain connection between gene expression and homoeostasis, cell products, and functions

Explain how a single mediate gene expression pathway can affect protein production

Explain mechanisms of gene expression Explain connections between genotype,

phenotype, and natural selection Explain viral cycles and how viral genetic

variation occurs Explain basic cellular communication and cell

signaling pathways Explain cell-to-cell direct communication and chemical

signals


Explain key parts of signal transduction pathways and cellular response

Explain how drugs can affect signal reception and therefore signal transduction pathways

Explain how organisms change behavior in response to external cues

Types of nervous systems, development of human nervous system, details on parts of the brain and neurologic processes

Explain, the words and pictures, how nervous systems detect external and internal signals, transmit, integrate, and send responses

Big Idea 4: Biological Systems Interact

Explain biological molecules, their properties, and their monomer units

Explain how monomer sequence determines a polymers properties

Explain interactions between cell organelles and explain how these do essential functions

Explain how gene expression and stimuli result in specialized cells, tissue, and organs

Explain information required to study community interactions

Explain how changes in a population can affect a community

Explain community interactions and movement of energy/matter


Predict the movement of energy/matter through a community

Explain how molecular interactions affect structure and function

Explain how cooperative interactions inside an organism promotes efficient use of energy/matter

Explain how population interactions affect species distribution and abundance

Explain how ecosystems can change over time due to large-scale events

Explain consequences of human actions on both local and global scales

Explain how changing molecular units give cells more variation in functions


Explain connection between environmental factors and phenotype and genotype

Explain how various phenotypic responses to an environmental factors lead to genotypes variation in a population

Predict survivorship/fitness of a population based on environmental factors

Explain connections between species diversity and ecosystem stability
