Scientific Methods and Microscopes - Study Notes

Flashcards covering key concepts from the study notes on scientific methods and microscopes.

Scientific Methods

A systematic method to explore natural phenomena using testable, falsifiable hypotheses.

Hypothesis

A testable statement that can be proven false.

Independent Variable

The variable that is manipulated in an experiment.

Dependent Variable

The variable that is measured in an experiment.

Control Group

A baseline group used for comparison in an experiment.

Compound Light Microscope

A microscope used for viewing thin, transparent specimens.

Total Magnification

multiply the magnification of the ocular lens and the objective lens.

Depth of Field

The thickness of the specimen that is in focus at one time when viewed through a microscope.

Wicking

A technique to introduce solutions without lifting the cover slip.

Field of View

The extent of the observable area seen through the microscope.

Limitations of Scientific Methods

Scientific methods cannot test supernatural or moral claims and must be measurable and objective.

Replication

The process of repeating trials in an experiment to verify results.

Working Distance

The space between the objective lens and the specimen.

Ocular Lens

The lens you look through in a microscope.

As magnification increases…fov…?

decreases
