The hydrosphere and atmosphere as heat sinks

I can describe how the hydrosphere and atmosphere store and release large amounts of heat, acting as heat sinks that moderate temperature.

Heat transfer in the water cycle

I can describe and explain how heat is transferred as water changes state through the water cycle.

Heat transfer and air and water currents

I can explain how uneven heating drives convection currents in the air and oceans.

Heat transfer and weather systems

I can explain how heat transfer affects the development, severity, and movement of weather systems.

Analyzing weather data to forecast

I can analyze meteorological data over a time span and use it to predict future weather conditions.

Naming and writing chemical formulas

I can name and write formulas for common ionic and molecular compounds using the periodic table and a list of ions.

Balancing equations and conservation of mass

I can represent a chemical reaction with a balanced symbolic equation that shows mass is conserved.

Classifying reactions by type

I can classify a chemical reaction by its type from the pattern of its reactants and products.

Classifying acids, bases, and salts

I can classify a substance as an acid, a base, or a salt from its characteristics, name, and formula.

Neutralization reactions

I can describe how neutralization tempers an acid with a base, moving the mixture toward neutral and forming a salt and water.

Factors that affect reaction rate

I can explain how heat, concentration, light, and surface area affect the rate of a chemical reaction.

The variables of motion

I can describe the variables of motion — distance, displacement, speed, velocity, and time — and how they relate.

Displacement, velocity, and time

I can analyze the relationship among displacement, velocity, and time mathematically to solve motion problems.

Graphing uniform motion

I can read and analyze a position-time graph for uniform motion, where velocity is constant.

Instantaneous and average velocity

I can distinguish between instantaneous velocity and average velocity and know when each applies.

Graphing non-uniform motion

I can read and analyze a position-time graph for non-uniform motion, where velocity is changing.

Velocity, time, and acceleration

I can describe and calculate the relationship among velocity, time, and acceleration.

WHMIS and safe handling of lab materials

I can apply WHMIS standards to select proper techniques for handling and disposing of lab materials safely.

Displaying data in graphs and tables

I can compile data and display it in the right format — a table, graph, or scatter plot — so that patterns are clear.

Similar ecosystems in different places

I can explain why ecosystems with similar characteristics can arise in different geographical locations.

Population equilibrium and resource limits

I can explain how natural populations are kept in equilibrium and connect this to an ecosystem's resource limits.

Cycling of matter through an ecosystem

I can illustrate and explain how carbon, nitrogen, and oxygen cycle through the living and non-living parts of an ecosystem.

Soil composition and fertility

I can describe how soil composition and fertility can change and how those changes affect an ecosystem.

Bioaccumulation through the food chain

I can describe how bioaccumulation works and explain its impact on consumers at higher trophic levels.

Impact of external factors on an ecosystem

I can analyze how external factors, natural and human-caused, affect an ecosystem.

Biodiversity and sustainability

I can explain how the biodiversity of an ecosystem contributes to its sustainability and resilience.

Short-term stress and long-term change

I can explain why ecosystems respond differently to short-term stresses than to long-term changes.
