5th Grade Science Matter & Mixtures

Front

What is density?

Back

Density is the mass of an object divided by its volume. It determines whether an object will float or sink in a fluid.

Front

What happens to an object with low density in water?

Back

An object with low density will float in water.

Front

What is a mixture?

Back

A mixture is a combination of two or more substances that are not chemically bonded and can be separated by physical means.

Front

What is a physical property?

Back

A physical property is a characteristic of a substance that can be observed or measured without changing its chemical composition.

Front

What is a solution?

Back

A solution is a homogeneous mixture where one substance (the solute) is dissolved in another (the solvent).

Front

What is the best method to separate magnetic and non-magnetic objects?

Back

The best method is to hold a magnet above the mixture and see which items move toward the magnet.

Front

What is relative density?

Back

Relative density compares the density of an object to the density of a fluid, often used to determine if it will float or sink.

Front

What is the state of matter that has no specific volume or shape?

Back

Gas has no specific volume or shape, and its particles move freely.

Front

What is the difference between a mixture and a compound?

Back

A mixture is a physical combination of substances, while a compound is a substance formed when two or more elements chemically bond.

Front

What is filtration?

Back

Filtration is a process used to separate solids from liquids or gases using a filter.
