A substance that can flow and take the shape of its container. Examples include liquids and gases.

A system used to identify and classify hazardous materials.

The amount of a dissolved substance in a solution.

The ability of a substance to dissolve in another substance.

A model that explains the behaviour of matter based on the idea that all matter is made up of tiny particles in constant motion.

The resistance of a fluid to flow. The thicker the fluid, the higher its viscosity.

The amount of matter contained in a given volume. Density is often expressed in grams per cubic centimetre (g/cm³).

The upward force that a fluid exerts on an object.

Never pour liquids directly into containers held in your hand. Use a test tube rack for support while pouring.

Always use a test tube rack to hold a test tube while pouring substances into it.

Clean up any spills immediately, following your teacher's instructions.

Never look directly into the top of a test tube or container. Always look through the sides.

Never use cracked or broken glassware. Report any broken glass to your teacher and dispose of it according to instructions.

Label any container you put chemicals in to prevent confusion and accidents.

Report all accidents and spills immediately to your teacher.

Understand the WHMIS (Workplace Hazardous Materials Information System) symbols on chemicals to ensure safe handling.

A symbol used to warn about the dangers of a substance, with a specific shape and color.

A set of rules and guidelines designed to ensure safety while working in a lab or handling hazardous materials.

A system designed to provide information about the hazards of a product and the necessary precautions to handle it safely.

A short warning or instruction usually found on a label to highlight a specific risk or safety precaution.

A collection of different substances mixed together, but not chemically combined.

The act of removing contaminants or unwanted substances from a mixture.

The process of identifying and describing the properties of a substance or mixture.

A water pump designed for developing countries that is durable, affordable, easy to maintain, and can be manufactured locally.

The pump design had to be simple enough for villagers to maintain and repair themselves.

The new pump was made of PVC, which is inexpensive and readily available around the world, unlike the traditional materials of iron and steel.

The pump design is adaptable to the needs of different communities. For example, in Sri Lanka, they used a locally made leather washer instead of a plastic one.

Using local materials and adapting the design to the specific needs of a community ensures sustainability and success.

In Malawi, the spigot on the pump is made of black metal because hyenas chewed through the original white plastic ones.

The new hand-operated water pump was based on a design from a Mennonite community in southern Ontario. This demonstrates the value of using existing knowledge and technologies as inspiration.

The new PVC pump was light, sturdy, cheap to build, and easy to install and maintain.

The substance that dissolves in a solution. For example, in orange juice, the orange solids are the solute.

The substance that does the dissolving in a solution. In orange juice, water is the solvent.

A solution that has a high amount of solute relative to the solvent. For example, frozen orange juice concentrate.

A solution that has a low amount of solute compared to the solvent. For example, orange juice after adding water to concentrate.

Describes the amount of solute dissolved in a specific amount of solvent. It tells you how much solute is present.

A way to express concentration. It tells you the number of grams of solute per 100 mL of solution.

The ability of a substance to dissolve in another substance. Different substances have different solubilities.

A mixture where one substance is dissolved evenly throughout another. Solutions are homogeneous mixtures.

A solution with a higher concentration has more solute dissolved in the same amount of solvent.

A solution with a lower concentration has less solute dissolved in the same amount of solvent.

The process of determining the concentration of a solution.

To compare concentrations of different solutions, you need to determine the amount of solute in the same volume of solvent.

In a solution, the substance being dissolved is called the solute.

In a solution, the substance doing the dissolving is called the solvent.

A homogeneous mixture of two or more substances.
