Practice lesson

Topic 1.1 - Learning Goals:

I can…

• Explain what makes something a substance
• Describe a substance using its properties and use properties to identify a substance
• Know the difference between a pure substance and a mixture
• Understand the difference between a homogeneous mixture and heterogeneous mixture
• Decide if a liquid mixture is a solution or a suspension based on its properties
• Explain the different ways a mixture can be separated by using separation methods

1.1 - Separation methods:

• Extraction

Separation based on difference in solubility

• Filtration

Separation based on difference in particle size

• Evaporation

Separation based on difference in boiling point

Topic 1.2 - Learning Goals:

I can…

• Use the different prefixes in the metric system to convert between measurements
• Explain what mass and volume are and what units are used to measure them
• Correctly determine the mass of an object or substance by using a scale
• Calculate the volume of a regularly shaped object by using a mathematical formula
• Determine the volume of an irregularly shaped object by using the water displacement method 

1.2 - Volume:

Regular shapes you can calculate the volume using a formula

1.2 - Water displacement:

Irregular shapes you can measure the volume using water displacement.

Topic 1.3 - Learning Goals:

I can…

• Explain the concept of density and know which measurements are necessary to calculate the density of a substance 
• Calculate the density of a substance, in g/mL or g/cm3, using the density formula.
• Use density to determine the mass or volume of a substance by making a calculation
• Use density to identify an unknown substance, since density is a property of a substance 

1.3 Density calculations
