Scientific Method and Hypothesis Validity

A systematic process used to investigate phenomena, gather data, and draw conclusions. It involves observation, hypothesis formation, experimentation, analysis, and communication of findings.

A testable prediction that can be supported or refuted through experimentation. It should be specific, measurable, achievable, relevant, and time-bound (SMART).

The independent variable is what the experimenter manipulates, while the dependent variable is the response or outcome being measured. Controlled variables are kept constant throughout the experiment.

The cell is the fundamental unit of life, capable of carrying out essential life processes. Cells are organized into tissues, organs, organ systems, and ultimately, organisms.

The process by which living organisms maintain a stable internal environment despite external changes. It involves regulating factors such as temperature, pH, and fluid balance.

The scientific method is a systematic process for investigating phenomena. It involves observation, forming a hypothesis, designing and conducting an experiment, analyzing data, and drawing conclusions. The results are then communicated to others.

A valid hypothesis is a testable prediction that can be supported or refuted through experimentation. It must be specific, measurable, achievable, relevant, and time-bound (SMART).

In an experiment, the independent variable is what the experimenter changes. The dependent variable is what is measured in response to the independent variable. Controlled variables are kept constant to ensure a fair test.

The cell is the smallest unit capable of carrying out all life processes. It is the basic building block of all living organisms.

Homeostasis is the ability of an organism to maintain a stable internal environment despite changes in the external environment. It is essential for survival.
