Homogeneous & Heterogeneous
A mixture that is the same everywhere.
What is a homogeneous mixture?
This scientist is known for her work in radioactivity.
Who is Marie Curie?
This property of a substance does not change, regardless of the amount of substance.
What is an intensive property?
This method of separation uses a barrier to seperate solids from liquids.
What is filtration?
This is the unit to measure concentration.
What is percentage %?
A mixture that has visibly different parts or phases.
What is a heterogeneous mixture?
This scientist is known for the Theory of Relativity.
Who is Albert Einstein?
This property of a substance varies when the amount of substance changes.
What is an extensive property?
This tool is best for measuring mass in a chemistry lab.
What is an analytical balance?
This is the unit to measure molarity.
What is moles/L?
One of the characteristics of this mixture is that all of its parts are evenly distributed.
What is a homogeneous mixture?
This scientist is known for the periodic table.
Who is Dmitri Mendeleev?
This extensive property describes how much space a substance occupies.
What is volume?
This method of separation brings a liquid to its boiling point to separate it from solids or liquids with higher boiling points.
What is distillation/evaporation?
The substance that is dissolved in a solution.
What is solute?

Examples: Salad, pizza, sand and water, oil and water, soda and ice, ceral and milk, trail mix, etc.
This scientist is known for the process of Pasteurization.
Who is Louis Pasteur?
This intensive property describes the amount of mass contained in a given volume.
What is density?
This laboratory tool is used to heat substances.
What is bunsen burner?
This change to the solution would result in an increase on the concentration of the solution.
What is adding more solute?
In 30 seconds, name 5 homogeneous mixtures.
Examples: Saltwater, vinegar, air, sugarwater, coffee, perfume, sodas, etc.
This is the element Marie Curie discovered.
What is radium?
In 30 seconds, name 3 intensive and 3 extensive properties.
Examples of intensive: density, boiling point, melting point, color, and hardness.
Examples of extensive: mass, volume, length, area, and energy.
