Science, Grade 7

Pure substances and mixtures

I can use particle theory to tell pure substances from mixtures.

Separating solutions and mixtures

I can choose and use methods to separate the parts of a mixture, like filtering or evaporating.

Solubility and concentration

I can analyse what affects solubility (how much dissolves) and concentration (how much is dissolved in a liquid).

Measuring water health with probeware

I can use probeware to measure indicators of a waterway's health, like temperature, pH, and dissolved oxygen.

Analysing a waterway's health

I can analyse water-quality data to judge how healthy a local waterway is.

Water purification and pollution cleanup

I can describe methods for purifying water and cleaning up water pollution.

Interactions of organisms in an ecosystem

I can analyse how organisms interact in an ecosystem through feeding, competing, and helping.

Human impact on ecosystems

I can analyse how humans harm and help ecosystems, including through pollution and green technologies.

Resource management and Netukulimk

I can analyse resource choices for sustainability, guided by the Mi'kmaw concept of Netukulimk.

Energy flow and matter recycling

I can explain how energy enters an ecosystem and flows through it, and how matter is recycled.

Biotic and abiotic connections

I can analyse how biotic (living) and abiotic (non-living) parts of nature are interconnected, including a Mi'kmaw perspective.

Biological indicators of health

I can explain how certain living things act as biological indicators of environmental health.

Ways species can be classified

I can classify species in more than one way, using different characteristics.

Hypothesizing how organisms adapt

I can hypothesize how organisms might adapt in response to their environment and predators.

Natural selection and evolution

I can explain natural selection and how it drives evolution over many generations.

Evidence of evolution

I can describe the kinds of evidence that support evolution, like fossils and shared body structures.

Strategies for conservation and sustainability

I can select conservation and sustainability strategies that fit a real environmental problem.

Community stewardship initiatives

I can describe community initiatives that care for the environment and how people take part.

Making a stewardship plan

I can formulate an environmental stewardship plan to reduce harm, guided by the concept of Netukulimk.

Strength of shapes and materials

I can evaluate which shapes and materials are strongest for building.

Applications of shapes and materials

I can evaluate why certain shapes and materials are chosen for real construction jobs.

Properties of construction materials

I can investigate the properties of construction materials, like strength, stiffness, weight, and durability.

Manufactured and natural structures

I can compare manufactured structures (built by people) with natural structures and their shared features.

Forces on and within structures

I can identify the forces that act on and within a structure, like compression and tension.

Testing structures to failure

I can test a structure to find where and how it fails under load.

Forces that cause structural failure

I can analyse how forces lead a structure to fail, and how to prevent it.

Static and dynamic forces

I can compare static forces (steady) with dynamic forces (moving or changing) on structures.

Applying design concepts

I can apply what I know about shapes, forces, strength, stability, and efficiency to plan a structure for a challenge.

Choosing materials for the challenge

I can evaluate and choose materials that best fit my design challenge.

Building the structure

I can carry out my plan to build a structure for the design challenge.

Testing against challenge criteria

I can test my structure against the challenge criteria and judge how well it met them.

Geographic features and plate boundaries

I can analyse how geographic features like mountains and volcanoes relate to the boundaries of Earth's plates.

Evidence for plate movement

I can analyse the evidence that Earth's plates move, like matching coastlines and fossils on different continents.

Erosion and deposition

I can explain erosion (wearing away and carrying material) and deposition (dropping it) and how they shape the land.

Technologies that measure geological change

I can describe technologies used to measure geological change, like seismographs and satellites.

Weathering and erosion

I can explain weathering (breaking rock down) and erosion (carrying it away) along a coastline.

Impact of waves and tides

I can analyse how waves and tides shape rivers and coastlines.

Protecting the coast

I can compare strategies to reduce coastal degradation, like planting dune grass, building barriers, or restoring wetlands.
