What are quantitative observations?

Back

Quantitative observations are measurements that involve numbers, such as height, weight, or temperature.

What are models in science?

What is a test variable?

Back

A test variable is the variable that is changed or manipulated in an experiment to observe its effect on the outcome variable.

What is a constant in an experiment?

Back

A constant is a factor that remains the same throughout an experiment to ensure that the results are valid.

Front

What is the purpose of conducting experiments?

Back

The purpose of conducting experiments is to test hypotheses and understand the relationships between variables.

Front

What is qualitative observation?

Back

Qualitative observation involves descriptions that do not use numbers, such as colors, textures, or smells.

Why do scientists use the scientific method?

Back

Scientists use the scientific method to systematically investigate questions and gather evidence to support or refute hypotheses.
