Grade 7 Science: how to help at home
What your child learns in Grade 7 science in the Prince Edward Island Curriculum, and simple things to try at home.
The Big Ideas this year
- Interactions with Ecosystems.
- Earth’s Crust.
- Heat.
- Mixtures and Solutions.
Easy ways to practise science at home
- Turn everyday questions into investigations: “Which paper towel holds the most water?”
- Read a science news story together and ask what evidence it gives.
- Look up how a household machine works, such as a bike gear, a lamp or a fridge.
- Have your child draw and label a diagram of something they just learned.
What each unit covers
Ecosystems
Biotic and abiotic parts of an ecosystem, how they interact, and the limiting factors and carrying capacity that decide how many organisms an ecosystem can support.
Food Chains & Energy
Producers, consumers and decomposers, food chains and webs, how energy shrinks as it passes up a chain (about 10% each step), and what happens when part of a chain changes.
Cycles & Succession
How water, carbon and nitrogen are cycled through ecosystems, why cycling supports sustainability, and the difference between primary and secondary succession.
People & Ecosystems
How agriculture, harvesting and technologies affect ecosystems, such as monoculture, overfishing, invasive species and runoff, and ways to protect and restore balance. Includes reading simple data about an environmental measure.
Restless Earth
Earth's layers, plate tectonics, earthquakes and volcanoes, fossils in rock layers, and the order of major events in Earth's 4.6-billion-year history. Includes how First Nations oral histories and scientific evidence together date the great 1700 earthquake.
Rocks & Minerals
Practises how rocks and minerals make up Earth’s crust, how to tell them apart and how rocks change in the rock cycle.
Weathering & Erosion
Practises how weathering, erosion and deposition wear down and rebuild Earth’s surface, including coastlines and soils.
Heat & Particles
Heat as energy linked to particle motion, temperature, expansion and contraction, changes of state, and the ways heat is generated (friction, electricity, burning, chemical reactions and the Sun).
Moving Heat
How heat is transmitted by conduction, convection and radiation, how the Sun's radiation heats different surfaces, and technologies such as insulation and double-pane windows that reduce heat loss.
Particles & Mixtures
The particle theory of matter, the states of matter, pure substances versus mixtures, and homogeneous versus heterogeneous mixtures.
Solutions & Separating
Solutes, solvents and solubility, what makes things dissolve faster, saturated and unsaturated solutions, concentration, why water is called the universal solvent, ways to separate mixtures, and some environmental effects of industrial separation.
What the report card levels look like at home
- Beginning
- Just getting started with this idea. Short, regular practice with lots of support helps most.
- Approaching
- Understands parts of it and is building confidence. Keep practising the tricky parts.
- Meeting
- Has it! Mixed review now and then keeps it strong.
- Exceeding
- Applies it confidently, even in new or harder situations. Try challenge mode and real-life problems.
Your child’s teacher decides the level on the report card. Read the PEI report card guide.
Common questions
Turn everyday questions into investigations: “Which paper towel holds the most water?” Read a science news story together and ask what evidence it gives. Keep sessions short, about 10 to 15 minutes, and stop on a success.
The Prince Edward Island Curriculum Grade 7 science units include ecosystems, food chains & energy, cycles & succession, people & ecosystems, restless earth, rocks & minerals.
