Red "sharps" container

for non-infectious sharps

ex of non-infectious sharps

test tubes, pipettes, broken glass ware, and dissecting pins

Red "infectious waste" container

for infectious sharps, or any waste containing blood

White bucket lined with red bag

for biological waste such as microbial cultures, labeled "animal waste," for waste from dissected specimens

what should you NEVER mix

biological waste and animal waste

Waste Basket

can be used to dispose of ANY solid waste that is non-hazardous, non-infectious, and not a sharp.

1st step of scientific method

make an observation

2nd step of scientific method

ask/state a question

3d step of scientific method

state hypothesis

4th step of scientific method

state prediction

5ht step of scientific method

conduct controlled experiment

6th step of scientific method

analyze results

7th step of scientific method

form a conclusion

Hypothesis

potential answer to the question that can be tested

A hypothesis is a _____ explanation

possible

Predication

outcome we'd expect to see if hypothesis is correct

x=

independent variable

y=

dependent variable

Define IV

part of experiment that is manipulated or changed

Define DP

not manipulated or changed, DEPENDS on IV

controlled experiment tests what?

the hypothesis

controlled experiment consists of what?

Experimental group, and control group

Experimental group is _____ to the IV

exposed

Control group is _____ to the IV

NOT exposed

Control group is used as a

comparison

The experimental group does what in an experiment?

receives treatment

Control group does what in an experiment?

does NOT receive treatment

results of a test may either

support or contradict/oppose a hypothesis

results that support a hypothesis

can't prove its correct, but means it's likely correct

If results contradict a hypothesis its

probably not correct (unless there was a flaw)

If hypothesis is supported we should

add additional tests to confirm it, OR revise it to be more specific

If hypothesis is not supported, we should

come up with a new hypothesis

Iterative

involving repetition

A prediction is made based on what?

a hypothesis

Controlled variable is

all conditions that could affect results but do NOT because they are kept constant

Magnification

image of specimen is enlarged

Resolution

ability to distinguish two objects that are bery close together
