Curricular Competencies
Students are expected to be able to do the following:
Questioning and predicting
Questioning and predicting
Questioning and predicting
Matter is anything that has mass and takes up space. Energy is the ability to cause change or do work. The universe is made up of matter and energy.- Key questions about matter and energy:
- What is the relationship between matter and energy and the cell theory?
- How do matter and energy connect to the kinetic molecular theory?
Demonstrate a sustained intellectual curiosity about a scientific topic or problem of personal interest
Make observations aimed at identifying their own questions about the natural world
Identify a question to answer or a problem to solve through scientific inquiry
Formulate alternative “If…then…” hypotheses based on their questions
Make predictions about the findings of their inquiry
Planning and conducting
Collaboratively plan a range of investigation types, including field work and experiments, to answer their questions or solve problems they have identified
Measure and control variables (dependent and independent) through fair tests
Observe, measure, and record data (qualitative and quantitative), using equipment, including digital technologies, with accuracy and precision
qualitative
evidence expressed through words, descriptions, interviews, narratives quantitative
evidence expressed through numbers and measurement accuracy
how close a measured value is to the actual value precision
how close measurements of the same type are to each other Use appropriate SI units and perform simple unit conversions
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, and local knowledge as sources of information
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. Construct and use a range of methods to represent patterns or relationships in data, including tables, graphs, keys, models, and digital technologies as appropriate
Seek patterns and connections in data from their own investigations and secondary sources
Use scientific understandings to identify relationships and draw conclusions
Evaluating
Reflect on their investigation methods, including the adequacy of controls on variables (dependent and independent) and the quality of the data collected
Identify possible sources of error and suggest improvements to their investigation methods
Demonstrate an awareness of assumptions and bias in their own work and secondary sources
Demonstrate an understanding and appreciation of evidence (qualitative and quantitative)
Exercise a healthy, informed skepticism and use scientific knowledge and findings from their own investigations to evaluate claims in secondary sources
Consider social, ethical, and environmental implications of the findings from their own and others’ investigations
Applying and innovating
Contribute to care for self, others, community, and world through personal or collaborative approaches
Co-operatively design projects
Transfer and apply learning to new situations
Generate and introduce new or refined ideas when problem solving
Communicating
Communicate ideas, findings, and solutions to problems, using scientific language, representations, and digital technologies as appropriate
Express and reflect on a variety of experiences and perspectives of place
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?
- As you consider the significance, worth, or value of an outcome or finding, how can you show different ways of knowing?
- 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?
Content
Students are expected to know the following:
characteristics of life
characteristics of life
living things respire, grow, take in nutrients, produce waste, respond to stimuli, and reproduce; there is debate as to whether or not to classify viruses as living things cell theory and types of cells
cell theory
- living things are made of one or more cells
- all cells come from pre-existing cells
- the cell is a basic unit of life
types of cells
- prokaryotic and eukaryotic cells
- plant and animal cells
- cells contain structures that carry out essential functions
photosynthesis and cellular respiration
the relationship of micro-organisms with living things:
micro-organisms
- micro-organisms are key to nutrient recycling in ecosystems as they act as decomposers
- viruses and bacteria can cause disease and can also be used in industry (e.g., production of cheese and salami) and agriculture (e.g., production of striped tulips)
- basic functions of the immune systemimmune system
- the immune system provides a barrier to infections and a number of non-specific and specific responses to fight infection (e.g., fever, antibodies, phagocytes, inflammation)
- different populations have greater immunity to certain infections than other populations (e.g., impact of smallpox epidemic on First Peoples)
- vaccinationand antibioticsvaccinationvaccination can prevent the spread of infectious diseaseantibioticsantibiotics are effective only against living organisms, such as bacteria, and not against viruses; overuse of antibiotics can lead to the development of antibiotic-resistant strains of bacteria (“superbugs”)
- impacts of epidemicsand pandemicsepidemicsregional outbreaks (e.g., smallpox, measles)on human populationspandemicsglobal outbreaks (e.g., Spanish flu, SARS)
kinetic molecular theory
kinetic molecular theory
explains how particles move in different states atomic theory and models
atomic theory
provides evidence for the existence of atoms and molecules models
models can be used to represent:- the arrangement and motion of particles in different phases
- the arrangement of and forces that bind protons, neutrons, and electrons in an atom
- the quarks and leptons in protons, neutrons, and electrons
protons, neutrons, and quarks
protons, neutrons, and quarks
protons and neutrons (made of quarks) are held together in the nucleus by a strong nuclear force electrons and leptons
electrons and leptons
electrons (a type of lepton) are held at a distance from the nucleus through electromagnetism types and effects of electromagnetic radiation
types
types of electromagnetic radiation: the electromagnetic spectrum consists of radio, microwave, infrared, light, UV, X-ray, and gamma rays effects
effects of electromagnetic radiation: positive effects include cancer treatments; negative effects include sunburns light:
- propertiespropertiesproperties of light:
- acts like both a wave and a particle
- wavelength, amplitude, frequency
- behavioursbehavioursbehaviours of light:
- reflection, refraction, absorption, transmission, scattering
- images formed by lenses and mirrors
- effects of translucent, transparent, and opaque objects
- ways of sensingways of sensingways of sensing light: human vision, optical instruments, cameras
plate tectonic movement
plate tectonic movement
- types of plate movements
- plate boundaries
- earthquakes and volcanoes
major geological events of local significance
First Peoples knowledge of:
- local geological formations
- significant local geological events
layers of Earth
Note: Some of the learning standards in the PHE curriculum address topics that some students and their parents or guardians may feel more comfortable addressing at home. Refer to ministry policy regarding opting for alternative delivery.
