6th Grade Science MIDTERM REVIEW

Front

What is a homogeneous mixture?

Back

A homogeneous mixture is a mixture that has a uniform composition throughout, meaning the different components are not distinguishable.

Front

What is a heterogeneous mixture?

Back

A heterogeneous mixture is a mixture where the components are visibly distinguishable and not uniform throughout.

Front

Which material is most likely to float on water?

Back

Wood is most likely to float on water due to its lower density compared to water.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state, such as a roller coaster car at the top of a hill.

Front

How can you separate a homogeneous mixture?

Back

Homogeneous mixtures cannot be separated by physical means like filtration; they require chemical processes.

Front

What is an example of a homogeneous mixture?

Back

An example of a homogeneous mixture is coffee, where the components are evenly distributed.

Front

What is an example of a heterogeneous mixture?

Back

An example of a heterogeneous mixture is a salad, where the individual ingredients are easily distinguishable.

Front

What does it mean for a substance to have uniform composition?

Back

Uniform composition means that the substance has the same proportions of its components throughout.

Front

What is density?

Back

Density is the mass of a substance divided by its volume, often determining whether an object will float or sink.

Front

What happens to potential energy as an object falls?

Back

As an object falls, its potential energy decreases while its kinetic energy increases.
