Florida Eoc Review Nature Of Science

Front 1

Conclusion

Back 1

The acceptance or rejection of an hypothesis based on observations made during an experiment.

Front 2

Control group aka control

Back 2

The subjects of an experiment that do not get the experimental treatment. This group is used to compare the results of the experiment to what might happen if no treatment was used.

Front 3

Data

Back 3

recorded observations (often what is seen or measured during an experiment)

Front 4

Quantitative Data

Back 4

Data that can be recorded as numbers. (example 5 apples, 3 seconds, etc)

Front 5

Qualitative Data

Back 5

Data observed using the senses and does not involve numbers (example, color, texture, odor, etc)

Front 6

Dependent Variable

Back 6

The resulting factor in an experiment. It is what you measure and record as data.

Front 7

Independent variable

Back 7

The factor in an experiment that is being tested. The thing that the experiment changes when the experiment is first set up.

Front 8

Hypothesis

Back 8

The predicted outcome of an experiment (based on doing background research). Often written in an if...then...because statement/

Front 9

Inference

Back 9

Using available scientific data to come to a conclusion.

Front 10

Observation

Back 10

Using the five senses to study the world.

Front 11

Scientific Method

Back 11

A process of inquiry that uses the principles of observation and experimentation to answer scientific questions.

Front 12

Scientific Theory

Back 12

An explanation for a wide range of observations and experimental results. It is backed with evidence but may change when new evidence is uncovered. Explains why....

Front 13

Scientific Law

Back 13

A scientific law is a statement based on repeated experimental observations that describes some aspects of the universe. Does not explain why is unlikely to change.

Front 14

Compound Light microscopes (include how it works and the pros and cons)

Back 14

A scientific device that uses light and lenses to magnify an image. Pros: can view living organisms. Cons: does not get as big as other devices.

Front 15

Scanning Electron Microscope (Include how it works and the pros and cons)

Back 15

A specimen is coated in metal and an electron beam is bounced of off the item. Pro: huge magnification, views the surface of an item giving a 3D appearance. Con: the process kills the specimen so cannot view live items.

Front 16

Transmission Electron Microscope.

Back 16

A very thin slice of the specimen is viewed by bouncing electrons off of the specimen. Pros Large magnification, views the inside of the specimen. Con: cannot view living specimens
