What is the difference between a base unit and a derived unit?

• Base units are fundamental and defined by physical constants, while derived units are combinations of base units.

• Base units are used in chemistry, while derived units are used in physics.

• Base units are larger than derived units.

• Base units are only used in the metric system.

What is density?

• The amount of mass in a given volume

• The speed of an object

• The temperature of a substance

• The color of a material

Explain in terms of density why a grocery bag containing all canned goods is harder to lift than a grocery bag containing all paper goods.

• Canned goods have a higher density than paper goods, making them heavier.

• Paper goods have a higher density than canned goods, making them heavier.

• Both canned and paper goods have the same density.

• Density does not affect the weight of the goods.

How can you obtain an object’s volume if you know its density and its mass?

• Divide the mass by the density

• Multiply the mass by the density

• Add the mass and the density

• Subtract the density from the mass

What is the three-part process for problem solving?

• Identify the problem, develop a strategy, implement the solution

• Brainstorm, execute, evaluate

• Plan, act, review

• Research, analyze, conclude
