Science, Grade 8

The cell as a living system

I can explain how a cell shows the characteristics of life and how substances move into and out of cells.

Single-celled, multicellular, and cell division

I can tell single-celled from multicellular organisms and explain how cell division supports growth and reproduction.

Plant and animal cell structures

I can identify cell structures, explain their functions, and compare plant and animal cells.

Microscope proficiency

I can prepare a slide, focus a compound light microscope safely, and calculate its magnification.

Levels of organization in the body

I can describe how cells, tissues, organs, and organ systems relate in the human body.

Careers in health and the human body

I can name careers that depend on understanding cells and human body systems.

Systems working together

I can explain how organ systems work together to keep the body healthy.

Lifestyle and body systems

I can analyze how lifestyle choices affect body systems and investigate the body's response to activity.

The body's responses and support technologies

I can describe how the body responds to stimuli and discuss technologies that support failing body systems.

Light travels in straight lines

I can show that light is energy that travels in straight lines.

Reflection

I can measure angles of incidence and reflection and state the relationship between them.

Refraction

I can describe how light refracts as it passes between materials and predict the bend.

Concave and convex mirrors and lenses

I can investigate how concave and convex mirrors and lenses form images.

Ray diagrams and optical devices

I can draw ray diagrams for optical devices and design a simple optical device.

The eye as an optical instrument

I can illustrate how the eye forms an image and compare it to a camera and other animals' eyes.

Colour and vision technologies

I can explain how we see colour and describe technologies that enhance vision.

The electromagnetic spectrum

I can describe and compare types of electromagnetic radiation across the spectrum.

Radiation-based technologies

I can analyze a radiation-based technology and defend a position on its impact.

Measuring density

I can measure the density of a material using mass and volume.

Calculating density and temperature effects

I can calculate density and explain how temperature changes it.

Buoyancy and Archimedes' Principle

I can explain the buoyant force and how objects control whether they float or sink.

Forces and pressure in fluids

I can use force diagrams for objects in fluids and relate pressure, force, and area.

Designing a floating cargo vessel

I can design and test a floating vessel that carries the most cargo.

Viscosity

I can compare the viscosity of fluids and describe how temperature affects it.

Compressibility and pressure

I can explain why gases compress more than liquids and how pressure affects fluids.

Hydraulic and pneumatic systems

I can explain the principles behind hydraulic and pneumatic fluid systems and model one.

Water distribution and the water cycle

I can represent the distribution of water in Saskatchewan and the water cycle.

Threats to water systems

I can identify threats to Saskatchewan's water systems and how stakeholders' needs can conflict.

Weathering, erosion, and deposition by water

I can explain how water movement and waves shape the landscape.

Glaciation and icecaps

I can relate glaciers to Saskatchewan's landforms and describe the effects of icecap changes.

Factors affecting aquatic life

I can identify what affects productivity and species distribution in aquatic environments.

Measuring water quality

I can measure indicators of water quality and interpret the data.
