Front

What is the independent variable in an experiment?

Back

The independent variable is the factor that is changed or controlled in a scientific experiment to test its effects on the dependent variable. In the example, it is 'fertilizer vs no fertilizer.'

Front

What is the first step of the scientific method?

Back

The first step of the scientific method is 'Make observations.' This involves gathering information and noticing phenomena that lead to questions.

Front

Is a car driving at a constant speed in a straight line accelerating?

Back

No, a car driving at a constant speed in a straight line is not accelerating because acceleration involves a change in speed or direction.

Front

What does static friction respond to?

Back

Static friction arises in response to an attempt to move an object along a surface.

Front

What is diffraction in the context of light waves?

Back

Diffraction is the bending of light waves around an object or through an opening.

Front

Define the dependent variable in an experiment.

Back

The dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is the purpose of a control group in an experiment?

Back

The control group serves as a baseline to compare the effects of the independent variable, ensuring that the results are due to the variable being tested.

Front

Explain the concept of refraction.

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What is the difference between qualitative and quantitative data?

Back

Qualitative data describes characteristics or qualities (e.g., color, texture), while quantitative data involves numerical measurements (e.g., height, weight).

Front

What is the significance of making observations in scientific research?

Back

Making observations is crucial as it helps formulate questions and hypotheses, guiding the direction of the research.
