Landera's Scientific method

What is a scientific model?

Back

A scientific model is a physical representation or simulation of an object, system, or concept that helps to explain and predict phenomena.

What is an independent variable in an experiment?

Back

The independent variable is the factor that is deliberately changed or manipulated by the scientist to observe its effect on the dependent variable.

Front

Why must there only be one independent variable in an experiment?

Back

Having only one independent variable ensures that the results of the experiment can be attributed to that specific change, making the experiment valid.

Front

What are variables in the context of an experiment?

Back

Variables are factors or conditions that can change in an experiment, potentially affecting the outcome.

Front

What is the purpose of testing a hypothesis?

Back

Testing a hypothesis involves conducting an experiment to determine if the proposed explanation for a phenomenon is supported by evidence.

Front

What is a dependent variable?

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 a control group?

Back

A control group is a standard of comparison in an experiment that is not exposed to the independent variable, allowing for a baseline to measure the effect of the independent variable.

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 a hypothesis?

Back

A hypothesis is a testable statement or prediction about the relationship between two or more variables.

Front

What is the scientific method?

Back

The scientific method is a systematic process for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.
