asexual reproduction:
  • mitosis
    the process through which pre-existing cells make two identical copies of themselves
  • different forms
    different forms of asexual reproduction: fission, budding, cloning, spores, grafting
sexual reproduction:
  • meiosis
    the process through which sex cells (eggs and sperm) are formed by the dividing of a parent cell twice, resulting in four daughter cells
  • human sexual reproduction
    the result of humans having two parents is that offspring are not genetically identical to either parent
element properties as organized in the periodic table
The periodic table groups elements according to their atomic number and properties (e.g., atomic size, metals/non-metals/semi-metals, chemical families, diatomic elements).
The arrangement of electrons determines the compounds
  • ionic and covalent
  • names and formulas
formed by elements
circuits
  • basic components include power source, load/resistor (lightbulbs, etc.), conductor and switch
  • types of circuits include series, parallel, short circuits
  • current flow in a circuit: alternating current (AC) and direct current (DC)
— must be complete for electrons to flow
voltage, current, and resistance
voltage, current, and resistance are related:
  • Ohm’s Law (V=IR)
  • relative dangers of current and voltage
effects of solar radiation
solar radiation provides the energy required for most life on Earth, and is the root cause of wind and ocean currents, which distribute energy and nutrients around the planet, as well as the energy sources for the water cycle
on the cycling of matter and energy
matter cycles
  • e.g., water, nitrogen, carbon, phosphorous, etc.
  • human impacts on sources and sinks (e.g., climate change, deforestation, agriculture, etc.)
  • bioaccumulation and biomagnification
within biotic and abiotic components of ecosystems
sustainability of systems
a systems approach to sustainability sees all matter and energy as interconnected and existing in dynamic equilibrium    (e.g., carbon as a key factor in climate change, greenhouse effect, water cycle, etc.)
First Peoples knowledge of interconnectedness
everything is connected, from local to global; First Peoples perspectives on interconnectedness
and sustainability
First Peoples perspectives on sustainability of systems

Questioning and predicting

Questioning and predicting
An interaction is a kind of action that occurs when two or more objects have an effect on one another.  The interaction may be direct or indirect.  In a direct interaction, A has a direct effect on B.  An example of a direct interaction is wolves preying on elk.  In an indirect interaction, A has an effect on B that affects C. For example, ladybugs have an indirect effect on plants because they eat aphids.
  • Key questions about interactions:
    • How do the four spheres of the Earth interact?
    • How can understanding the interactions of Earth’s spheres help us prepare for natural disasters?
Demonstrate a sustained intellectual curiosity about a scientific topic or problem of personal interest
Make observations aimed at identifying their own questions, including increasingly complex ones, about the natural world
Formulate multiple hypotheses and predict multiple outcomes

Planning and conducting

Collaboratively and individually plan, select, and use appropriate investigation methods, including field work and lab experiments, to collect reliable data (qualitative and quantitative)
Assess risks and address ethical, cultural and/or environmental issues associated with their proposed methods and those of others
Select and use appropriate equipment, including digital technologies, to systematically and accurately collect and record data
Ensure that safety and ethical guidelines are followed in their investigations

Processing and analyzing data and information

Experience and interpret the local environment
Apply First Peoples perspectives and knowledge, other ways of knowing
Ways of knowing refers to the various beliefs about the nature of knowledge that people have; they can include, but are not limited to, Aboriginal, gender-related, subject/discipline specific, cultural, embodied and intuitive beliefs about knowledge.
, and local knowledge as sources of information
Seek and analyze patterns, trends, and connections in data, including describing relationships between variables (dependent and independent) and identifying inconsistencies
Construct, analyze and interpret graphs (including interpolation and extrapolation), models and/or diagrams
Use knowledge of scientific concepts to draw conclusions that are consistent with evidence
Analyze cause-and-effect relationships

Evaluating

Evaluate their methods and experimental conditions, including identifying sources of error or uncertainty, confounding variables, and possible alternative explanations and conclusions
Describe specific ways to improve their investigation methods and the quality of the data
Evaluate the validity and limitations of a model or analogy in relation to the phenomenon modelled
Demonstrate an awareness of assumptions, question information given, and identify bias in their own work and secondary sources
Consider the changes in knowledge over time as tools and technologies have developed
Connect scientific explorations to careers in science
Exercise a healthy, informed skepticism, and use scientific knowledge and findings to form their own investigations and to evaluate claims in secondary sources
Consider social, ethical, and environmental implications of the findings from their own and others’ investigations
Critically analyze the validity of information in secondary sources and evaluate the approaches used to solve problems

Applying and innovating

Contribute to care for self, others, community, and world through individual or collaborative approaches
Transfer and apply learning to new situations
Generate and introduce new or refined ideas when problem solving
Contribute to finding solutions to problems at a local and/or global level through inquiry
Consider the role of scientists in innovation

Communicating

Formulate physical or mental theoretical models to describe a phenomenon
Communicate scientific ideas, claims, information, and perhaps a suggested course of action, for a specific purpose and audience, constructing evidence-based arguments and using appropriate scientific language, conventions, and representations
Express and reflect on a variety of experiences, perspectives, and worldviews through place
Place is any environment, locality, or context with which people interact to learn, create memory, reflect on history, connect with culture, and establish identity. The connection between people and place is foundational to First Peoples perspectives of the world.
  • Key questions about place:
    • How does place inform your questions and inquiries?
    • How does place influence your ability to plan and conduct an inquiry and make predictions about outcomes?
    • How does your understanding of place affect the ways in which you collect evidence and evaluate it?
    • How can you demonstrate ways of knowing that your work and the work of others is valid, free of bias, and acknowledges limitations?
    • How can your understanding of place influence project designs?
    • How do the place-based experiences and stories of others affect the ways in which you communicate and collaborate?
    • How can you demonstrate an understanding of place and interconnectedness by the ways in which you represent the results of your investigation?
