Students are expected to be able to do the following:
Questioning and predicting
Questioning and predicting
Questioning and predicting
Cycles are sequences or series of events that repeat/reoccur over time. A subset of pattern, cycles are looping or circular (cyclical) in nature. Cycles help people make predictions and hypotheses about the cyclical nature of the observable patterns.- Key questions about cycles:
- How do First Peoples use their knowledge of life cycles to ensure sustainability in their local environments?
- How does the water cycle impact weather?
Demonstrate curiosity and a sense of wonder about the world
Observe objects and events in familiar contexts
Ask questions about familiar objects and events
Make simple predictions about familiar objects and events
Planning and conducting
Make and record observations
Safely manipulate materials to test ideas and predictions
Make and record simple measurements using informal or non-standard methods
Processing and analyzing data and information
Experience and interpret the local environment
Recognize First Peoples stories (including oral and written narratives), songs, and art, as ways to share knowledge
Sort and classify data and information using drawings, pictographs and provided tables
Compare observations with predictions through discussion
Identify simple patterns and connections
Evaluating
Compare observations with those of others
Consider some environmental consequences of their actions
Applying and innovating
Take part in caring for self, family, classroom and school through personal approaches
Transfer and apply learning to new situations
Generate and introduce new or refined ideas when problem solving
Communicating
Communicate observations and ideas using oral or written language, drawing, or role-play
Express and reflect on personal experiences 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:
- What is place?
- What are some ways in which people experience place?
- How can you gain a sense of place in your local environment?
- How can you share your observations and ideas about living things in your local environment to help someone else learn about place?
Content
Students are expected to know the following:
metamorphic and non-metamorphic life cycles of different organisms
metamorphic
metamorphic life cycles: body structure changes (e.g., caterpillar to butterfly, mealworm transformation, tadpoles to frog) non-metamorphic
non-metamorphic life cycles: organism keeps same body structure through life but size changes (e.g., humans) similarities and differences between offspring and parent
offspring and parent
a kitten looks like cat and a puppy looks like dog but they do change as they grow; salmon change a great deal as they grow and need fresh and salt water environments to survive First Peoples use of their knowledge of life cycles
First Peoples use of their knowledge
- stewardship: sustainably gathering plants and hunting/fishing in response to seasons and animal migration patterns (e.g., clam gardens, seasonal rounds, etc.)
- sustainable fish hatchery programs run by local First Peoples
physical ways of changing materials
physical
physical ways of changing materials:- warming, cooling, cutting, bending, stirring, mixing
- materials may be combined or physically changed to be used in different ways (e.g., plants can be ground up and combined with other materials to make dyes)
chemical ways of changing materials
chemical
chemical ways of changing materials: cooking, burning, etc. types of forces
forces
- contact forces and at-a-distance forces:
- different types of magnets
- static electricity
- balanced and unbalanced forces:
- the way different objects fall depending on their shape (air resistance)
- the way objects move over/in different materials (water, air, ice, snow)
- the motion caused by different strengths of forces
water sources including local watersheds
water sources
- oceans, lakes, rivers, wells, springs
- the majority of fresh water is stored underground and in glaciers
water conservation
water conservation
fresh water is a limited resource and is not being replaced at the same rate as it is being used the water cycle
water cycle
The water cycle is driven by the sun and includes evaporation, condensation, precipitation, and runoff. The water cycle is also a major component of weather (e.g., precipitation, clouds). local First People’s knowledge of water:
- water cycles
- conservation
- connection to other systemsconnection to other systemscultural significance of water (i.e., water is essential for all interconnected forms of life)
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.
