Front

Why did different groups have different data when measuring the speed of a toy car over different surfaces?

Back

Each group used a different length rug to collect their data.

Front

What is water vapor?

Back

Water vapor is the gaseous form of water that is present in the air.

Front

What is the principle of conservation of mass?

Back

The mass of an enclosed system remains constant over time, regardless of the processes happening inside.

Front

What is an inference in scientific investigation?

Back

An inference is a conclusion drawn from evidence and reasoning rather than from explicit statements.

Front

What is a testable question?

Back

A testable question is one that can be answered through experimentation and observation.

Front

What factors can affect the speed of a toy car?

Back

The surface type, the weight of the car, and the incline of the ramp can all affect the speed.
