Science and Technology, Secondary 2

What mass is

I can independently explain what mass is and compare the mass of different substances that take up the same space.

Heat and particle motion

I can independently explain how heating matter changes particle motion and how that defines temperature.

Naming the phase changes

I can independently name the phase changes of matter and read a phase-change diagram.

Acidic, basic and neutral solutions

I can independently test whether a common substance is acidic, basic, or neutral and describe what I observe.

Characteristic properties identify substances

I can independently explain what a characteristic property is and use one to identify or group substances.

Kinds of mixtures

I can independently describe what makes something a mixture and tell a homogeneous mixture from a heterogeneous one.

Physical changes

I can independently describe a physical change and recognize examples where the substance stays the same.

Chemical changes and their signs

I can independently spot the signs of a chemical change, explain it by the new properties, and name common types.

Dalton's atomic model

I can independently describe Dalton's atomic model and use it to represent a simple molecule.

Habitat and ecological niche

I can independently describe an organism's habitat and its ecological niche.

Species and populations

I can independently define a species, tell it apart from a population, and estimate numbers in a territory.

Adaptations for survival

I can independently describe physical and behavioural adaptations that help living things survive.

Evolution and natural selection

I can independently explain natural selection and how living things are classified.

The cell as the unit of life

I can independently explain that cells are the unit of life and tell an animal cell from a plant cell.

Cell parts and what they do

I can independently identify the main cell parts under a microscope and state each one's role.

Sexual and asexual reproduction

I can independently distinguish sexual from asexual reproduction and describe how plants reproduce.

Human reproductive organs and gametes

I can independently name the human reproductive organs and gametes and describe fertilization and development.

Contraception and preventing STBBIs

I can independently describe contraceptive methods and responsible behaviours around sexually transmitted and blood-borne infections.

Inside the Earth

I can independently describe Earth's internal layers and explain what the lithosphere is.

Relief and human activity

I can independently link the shape of the land to geological processes and to how people use it.

The three rock types

I can independently describe how the three rock types form and tell a rock from a mineral.

Classifying soil

I can independently classify a soil by what it is made of.

Fresh and salt water

I can independently describe how Earth's water is distributed and how the hydrosphere and atmosphere interact.

Layers and composition of the atmosphere

I can independently name the atmosphere's layers and describe what clean air is made of.

Plate tectonics and its effects

I can independently describe plate tectonics and the phenomena it causes.

Erosion, wind and the water cycle

I can independently describe erosion and the water cycle and tell renewable from nonrenewable energy.

Gravitation and light

I can independently define gravitation and describe basic properties of light.

Diagram of principles

I can independently read a diagram of principles and use it to explain how a simple object works.

Motion and force in objects

I can independently identify how parts move and describe what a force does in a technical object.

Parts of a technological system

I can independently identify a technological system and describe its parts and how they work together.

Energy transformations in objects

I can independently identify how energy is transformed inside a technical object.

Materials in technical objects

I can independently identify the materials in an object, trace their origin, and link a material to its use.

Tools, specifications and process sheets

I can independently name the tools of manufacture and follow a plan to build an object to specifications.
