Key ideas
A prototype is a working model built to test a design idea before anything final is made.
In Grade 7 the written plan includes the materials, three-dimensional sketches and the steps to follow, and the criteria include function, appearance, environmental considerations, cost and efficiency.
Test the prototype against each criterion, record the results, and use them to decide what to change.
Change one feature at a time, with a reason you can explain, so you know what made the difference.
Match the graph to the data: a line graph for a quantity that changes over time or with another measured variable, a bar or double-bar graph for categories, and a histogram for how often values fall in ranges.
Watch out for
- Thinking a prototype must be the finished product rather than a testable first version you refine.
- Building without measurable criteria, so you can't judge whether the prototype met its goal.
- Reading a trend from a graph without checking whether the axis scale is even or starts at zero.

Key ideas
An ecosystem is a place where living things interact with each other and with non-living things; the biosphere is all of Earth's ecosystems together.
Human interventions are actions that change ecological succession or which species live in an ecosystem.
A food web shows who eats whom; its feeding levels are producers, primary consumers (plant eaters), secondary consumers and tertiary consumers.
To make a wet mount, place the specimen in a drop of water on a slide and lower a cover slip at an angle to avoid air bubbles.
Biotic means living or once living (plants, animals, micro-organisms, fallen leaves); abiotic means non-living (water, light, temperature, minerals in soil).
Watch out for
- Using 'living' and 'biotic' loosely so that dead leaves or once-living things get mislabelled.
- Thinking all human impact on ecosystems is harmful, missing restoration and conservation as positive interventions.
- Thinking energy stays constant up a food chain, when most energy is lost as heat at each level.

Key ideas
Temperature measures how fast a substance's particles move on average; heat is energy transferred from a warmer object to a cooler one, by conduction, convection or radiation.
A scientific theory is an explanation of observations that has been tested repeatedly and shown to be consistent with the evidence, so it is generally accepted by scientists.
A heat conductor lets heat pass through it easily, as most metals do; a heat insulator slows heat transfer, as wool, foam, wood and still air do.
A pure substance is made of only one type of particle, such as distilled water, table salt or pure copper.
Some household substances, such as paints, solvents, motor oil, pesticides and batteries, can harm living things if they reach water, soil or air.
Watch out for
- Using 'heat' and 'temperature' as the same word, when temperature measures particle motion and heat is energy transfer.
- Thinking a scientific theory is 'just a guess', when it is a well-tested explanation supported by evidence.
- Thinking a material that feels warm is a good conductor, when good insulators often feel warm.

Key ideas
Structures are frame structures (a skeleton of parts, like a tower), shell structures (a thin outer layer, like an egg or a dome) or solid structures (filled throughout, like a dam).
External forces act on a structure from outside: loads such as people and snow, wind, water pressure, and the pull of gravity on the structure itself.
Corrugating, or folding a material into ridges, makes it much stiffer, as in corrugated cardboard and metal roofing.
Internal forces act inside a structure: compression squeezes, tension stretches, shear slides one part past another, and torsion twists.
The structure's own weight is its dead load; the changing forces placed on it, such as people, vehicles, snow and wind, are its live load.
Watch out for
- Using 'force' loosely without distinguishing compression, tension, shear, and torsion.
- Forgetting a structure's own weight when listing the forces on it, when its own weight, the dead load, is an external force it must always support.
- Thinking strength only comes from thicker material, overlooking folding, corrugating, and layering.

Key ideas
Earth's layers, from the outside in, are the crust, the mantle, the outer core and the inner core.
The rock cycle describes how any rock can become any other type of rock over very long times, often millions of years.
Soil is a mixture of weathered rock particles, humus (decayed plant and animal matter), water, air and living things; a few centimetres of it take hundreds of years to form.
The theory of plate tectonics says Earth's surface is broken into large plates that move a few centimetres a year over the slowly flowing mantle.
Weathering breaks rock down where it is (physically, biologically or chemically); erosion carries the pieces away by water, wind, ice or gravity.
Watch out for
- Using 'ground' or 'rock' loosely without the terms crust, mantle, and core for Earth's layers.
- Thinking a rock stays one type forever, missing that the rock cycle changes rock from one type to another.
- Thinking soil is just 'dirt' rather than a valuable resource that takes a very long time to form.
