 Solution

 What type of mixture has particles that are evenly distributed and cannot be seen with the naked eye? Something has dissolved in something.

100

 Filtration

 What separation technique is used to separate a solid from a liquid using a filter?

100

 Solute

 What term is used to describe the substance that dissolves in a solvent to form a solution?

100

 Magnetic separation

 What separation technique uses a magnet to separate magnetic materials from a mixture?

100

Independent variable

What term is used to describe the variable that is intentionally manipulated or changed in an experiment to study its effect on the dependent variable?

200

 Suspension

 What type of mixture has particles that are temporarily mixed and will eventually settle at the bottom?

200

 Evaporation

 What separation technique is used to remove a liquid from a solution by heating it until the liquid turns into gas?

200

 Solvent

 What term is used to describe the substance that dissolves a solute to form a solution?

200

 Decanting

 What separation technique involves pouring off a liquid to separate it from a settled solid or denser liquid?

200

Dependent variable

What term is used to describe the variable that is measured or observed in an experiment to see how it responds to changes in the independent variable?

300

 Colloid

 What type of mixture has particles that are evenly distributed and do not settle but are larger than those in a solution?

300

 Distillation

 What separation technique is used to separate two liquids with different boiling points by heating the mixture and collecting the gas?

300

 Concentration

 What term is used to describe the amount of solute in a given volume of solvent in a solution?

300

 Centrifugation

 What separation technique uses a spinning force to separate substances with different densities, like solids and liquids in a suspension?

300

Controlled variable

What term is used to describe a variable that is kept constant throughout an experiment to ensure a fair test and accurate results?

400

 Immiscible

 What term is used to describe two liquids that do not mix together, like oil and water?

400

 Crystallization

 What separation technique is used to form solid crystals from a solution by allowing the solvent to evaporate slowly?

400

 Dilute

 What term is used to describe a solution with a low concentration of solute?

400

 Sieving

 What separation technique is used to separate particles of different sizes by passing them through a mesh or perforated surface?

400

Replicate

What term is used to describe repeating an experiment multiple times to ensure consistent results and minimize the effects of random errors or variations?

500

 Miscible

 What term is used to describe two liquids that mix together evenly, like alcohol and water?

500

 Chromatography

 What separation technique is used to separate the components of a mixture based on their ability to move through a stationary phase?

500

 Saturated

 What term is used to describe a solution that contains the maximum amount of solute that can dissolve at a given temperature?

500

Gravity separation

What is a method of separating components of a mixture based on the differences in their specific densities?

500

Mean

What is calculated by adding up all the data points and then dividing the sum by the total number of data points?
