What is the study of life?
Biology
The Metric System uses what to measure mass?
Grams
The Metric System uses what to measure length?
Meters
The Metric System uses what to measure volume?
Liters
The molecule that contains the genetic code is called?
DNA
What is always changing and progressing?
Science
A personal point of view based on belief rather than science is?
Bias
The variable that is changed during the experiment?
Independent Variable
Temperature, light, time, and availability of nutrients are all what in experiments?
Variables
The variable that changes in response to the independent variable?
Dependent Variable
Well-tested explanation that unifies a broad range of observations and hypotheses. It can be revised as new information is found.
An explanation for a set of observations that can be tested in ways that support or reject it, is called?
Hypothesis
What is a logical interpretation based on information one already knows?
Inference
A signal to which an organism responds is called?
Stimulus
Well-tested explanation that unifies a broad range of observations and hypotheses and that enable scientists to make accurate predictions about new situations is called a what?
Theory
In the marsh grass experiment it might include notes about foreign objects in the plots, or whether the grass was growing upright or sideways. What kind of data is being used here?
Qualitative Data
When internal conditions in an organism remain stable, it is called?
Homeostasis
Ms. Greiner thinks that her four ferns that she has talked softly and lovely to are going to grow better than the one fern she yelled at. What is Ms. Greiner forming right now?
Hypothesis
In the marsh grass experiment, it could include the number of plants per ploy, plant sizes, and growth rates. What type of data is being used here?
Quantitative Data
In an experiment, Ms. Greiner decides to plant five ferns. Ms. Greiner decides that she is going to talk softly and loving to four of the plants and yell at one plant to see the effects of how they will grow. What is this experiment called?
Controlled Experiment
What are the stages of the scientific method?
State the question, collect information, form a hypothesis, test the hypothesis, record and study data, draw a conclusion
Ms. Greiner is doing an experiment with her three of her ferns. She decides that she is going to give each fern a different amount of water every day to see how that is going to affect the plant. What is the independent variable?
Amount of water
Ms. Greiner is doing an experiment with her three of her ferns. She decides that she is going to give each fern a different amount of water every day to see how that is going to affect the plant. What is the dependent variable?
Size of plant, number leaves, living or dead
What are four attitudes of good scientists?
Curiosity, Skepticism, Open-Mindedness, and Creativity
Ms. Greiner has finished both of her experiments with the ferns. She decides that she wants to share her data with the other Biology teachers down the hall to see if there were any errors in her work. What is this called when Ms. Greiner asks for them to review it?
Peer-Review
