Essential Question: How is scientific inquiry used as a tool to
understand the world?
- You will learn how to ask significant scientific
- You will know how to work safely.
- You will learn how to plan and do scientific experiments
You will critique scientific investigations for quality
by asking the following questions: Is your sample large enough? If you or
another person were to repeat the experiment, would the same results be obtained?
Are there different ways to test your question? Are there other ways that you
could explain your results?
variables and using a control group when appropriate.
and using appropriate experimental materials.
recording, organizing, and analyzing data.
findings to others.
Essential Question: What are living things made of?
- You will understand the structure and function of the
basic molecules from which all living things are made including: carbohydrates,
lipids, proteins, and nucleic acids.
- You will learn the basic
structure and function of enzymes and their importance to living things.
- You will understand the
basic chemical reactions that living things use to obtain and transform energy including:
aerobic respiration, anaerobic respiration, and photosynthesis.
Essential Question: How are living things related within the biosphere?
- You will investigate and analyze how living things are
related to one another within their population, communities, and ecosystems. To do this, we will focus on these topics:
You will investigate and analyze the impact of human
populations on both local and global environments, including:
- The abiotic
and biotic factors within a community and how they interact.
that affect the growth of a population.
- The basic
elements used by all living things and how these materials are recycled within an ecosystem.
movement of energy through an ecosystem.
and future changes in human population growth.
- How factors
such as climate change and resource use relate to human activities.
- Methods for conserving and minimizing destructive human
impact on the environment.
Essential Questions: What are cells made of? How are they specialized
for their function? How do they maintain homeostasis?
- You will learn that cells contain organelles including: the
plasma membrane, cell wall, mitochondria, vacuoles, chloroplasts, and ribosomes.
- You will learn that cells
are specialized to their function and can communicate with one another.
- You will investigate how cells move materials in and out
including: passive transport (diffusion, osmosis), active transport, and the
role of ATP as a source of energy.
Essential Question: How and why do cells divide?
- You will learn that certain conditions make it necessary
for cells to divide and that a cell goes through certain steps (mitosis and
cytokinesis) to divide asexually. This
allows for growth and repair of damaged cells, but also has implications for
Essential Questions: How can knowledge of DNA help us understand the
way that organisms are related to each other and how organisms change over
time? How does DNA technology impact
individuals and society today?
- You will analyze the molecular basis of heredity
including: DNA and RNA structure, DNA replication, protein synthesis, mutations
and their effect on the resulting protein, and gene regulation.
- You will compare asexual and sexual reproduction.
- You will interpret and predict patterns of inheritance
including the following: dominant, recessive, and intermediate traits, multiple
alleles, polygenic inheritance, sex-linked traits, independent assortment, test
cross, pedigrees, and Punnett squares.
- You will assess the impact of the Human Genome Project
and look at applications of biotechnology such as gel electrophoresis and transgenic
- You will examine the theory of evolution by natural
selection focusing on: the origin of life, fossil and biochemical evidence,
mechanisms of evolution, and applications such as pesticide and antibiotic
Essential Questions: How do scientists categorize living things? How do
living things accomplish life functions?
- You will look at how
scientists classify organisms based on their evolutionary relationships.
- You will learn how to identify an organism using a
- You will analyze the processes by which the following
groups accomplish basic life functions: protists, annelid worms, insects,
amphibians, mammals, and plants.
- You will describe adaptations that allow organisms to
survive and reproduce.
- You will examine how internal and external factors affect
the health of an organism.
- You will analyze patterns of animal behavior.
