100
The group that is being tested—getting the actual experiment
Experimental group
100
This is information organized in a column format with titles and units at the top
Data table
100
This is the part you look through, which usually has a magnification of 10x
eyepiece
100
Organisms maintain a dynamic equilibrium that sustains life.
homeostasis
100
Sweat shiver body temperature glucose levels
Negative feedback loop
200
The group that is not being tested (is unchanged), but rather is being used to check the validity of the experiment (may be getting a placebo*)
Control group
200
Finish this:
The effect of __________________ on _______________.
independent variable
dependent variable
200
Stage
Where the slide is placed
200
Organization levels of animals
IN ORDER SMALLEST TO LARGEST
organelles, cells, tissues, organs, organ systems, organisms
200
When the stoma on leave open this is an example of
Negative feedback loop
300
Not a real medication or intervention
placebo
300
Each axis should be labeled with
what information is being presented and its units
300
Doing this in a lab will get you a zero
Fooling around
Playing with lab materials
Breaking lab rules
Not following dorections
300
What are digestion, respiration, reproduction, circulation, excretion, movement, coordination, and immunity
Examples of life functions
300
This makes a bodily function more likely to increase
Positive feedback loop
400
The variables that are kept the same between the different groups so they don’t affect the experiment
Control variable
400
True or False:
It does not matter how you space the units on the axis
False
400
How to smell a chemical in a lab
wafting
400
These are like organs inside of cells
Organelles
400
This slows down or prevents a reaction
Negative feedback loop
500
The variable that the researcher is testing, or changing on purpose. When graphed, it goes on the X-axis.
Independent variable
500
When reading measurements from this instrument you look at the lowest curve of the liquid (meniscus)
Graduated cylinder
500
Stoppers in a test tube being heated can cause this.
Explode
500
Failure to maintain this may result in disease or death.
Homeostasis
500
These are molecules that speedup a chemical reaction
Enzymes
600
The variable that changes as a result of the independent variable. When it is graphed, it goes on the Y-axis
Dependent variable
600
This is the system that is used in science
metric system
600
A tool used to identify an organism
Dichotomous key
600
Childbirth is an example of this
Positive feedback loop
600
Enzymes and other molecules, such as hormones, receptor molecules, and antibodies, have these that influence both how they function and how they interact with other molecules.
