Big idea: People prepare for and respond to daily and seasonal change through clothing, shelter, activities and community services (E2.6). Innovations let people do activities all year (E1.1), and seasons affect society and the environment: flooding, farming, snow clearing (E1.2).
How to help: Before going outside, ask "What's the weather? What should we wear?" Talk about the community helpers you see working in each season (snowplow drivers, farmers, lifeguards, hydro crews).
About the design challenge (engineering design, A1.3): Let your child plan and build. Keep it fair: same-size ice cubes, same start time, same sunny spot. Encourage a second try after improving.
Indigenous perspectives: Snowshoes and toboggans are Indigenous technologies still widely used today. You can mention that different nations made different designs for their snow and land.
Common difficulties: Thinking inventions only mean machines. Clothing, shelters and snowshoes are innovations too.
Safety: Sun protection in summer; frostbite awareness in winter (cover skin when it is very cold).
