G7 Q2 Science Practice Assessment

Front

What is the scientific method?

Back

A systematic process used for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.

Front

What is a control in an experiment?

Back

A control is a standard against which the results of an experiment are compared, ensuring that the test conditions are consistent.

Front

What is replication in scientific experiments?

Back

Replication is the process of repeating an experiment to verify results and increase reliability.

Front

What are the three states of matter?

Back

Solid, liquid, and gas.

Front

How do particles behave in a solid?

Back

In a solid, particles are closely packed together and vibrate in fixed positions.

Front

How do particles behave in a liquid?

Back

In a liquid, particles are close together but can move past each other, allowing the liquid to flow.

Front

How do particles behave in a gas?

Back

In a gas, particles are far apart and move freely, filling the available space.

Front

What is wavelength?

Back

Wavelength is the distance between successive crests of a wave, often used to describe light and sound waves.

Front

How does temperature affect particle movement?

Back

As temperature increases, particles move faster due to increased energy.

Front

What is the relationship between heat and particle movement?

Back

The more heat particles contain, the faster they move.
