SciPro & Homeostasis

QuestionAnswer
Constant Constant factor throughout the experiment.
Dependent Variable Depends on the independent variable.
Independent Variable Established at the beginning of the experiment, influences dependent variable.
Control Group Group used to compare normal conditions to the experimental group.
Experimental Group that the experiment is being conducted on.
Hypothesis Used to identify the object of the experiment.
Theory A set of principles formed from an experiment.
What is Science? Science is a way to discover all the undiscovered about the universe and put it to the test.
1st Part of Scientific Method Define the problem
2nd Part of Scientific Method Research your problem
3rd Part of Scientific Method Create a hypothesis
4th Part of Scientific Method Design an experiment
5th Part of Scientific Method Test your hypothesis
6th Part of Scientific Method Organize your data
7th Part of Scientific Method Analyze data and draw conclusions
Is a hypothesis always true? A hypothesis is not always true which is why it must be tested.
What is the difference between quantitative and qualitative data? The difference between qualitative and quantitative data is that qualitative data uses the appearance of something and quantitative data is number based.
A student's experiment showed that mice move away from light. This statement is which part of the scientific process? Organizing the data.
After an experiment is completed, who should review your work? Peers and other scientists.
Can science theories be disproven? Science theories can be disproven.
How is a hypothesis written? A hypothesis is written by observing the problem and how one would solve the problem. Then making a question and figuring out what hypothesis best answers the question.
Which part refers to the independent variable? The independent variable is affecting the dependent variable. (Usually first variable introduced)
Which part refers to the dependent variable? The dependent variable follows the independent variable i.e. rise in temperature causing increase in insect populations. The dependent variable would be the insects.
What are constants ( controlled variables) in an experiment? They are the factors that remain constant through out the experiment. The beaker in an experiment. Ruler in ruler drop experiment.
How many variables should be tested in 1 experiment? One at a time. If you test multiple variables at a time the experiment may become chaotic.
Which group gets the independent variable? The group being tested gets the independent variable
What is the difference between the control and the experimental groups? The control is used to compare normal results and the experimental is used to compare the tested results.
When you set up your experiment, why should you consider the number of subjects or the number of trials you use? You should consider these things because more or less subjects can affect the amount of results and more conclusive results are better for an experiment. More trials will result in more data to be compared similar to more subjects.
Homeostasis when physiological processes maintain equilibrium
Biology the study of living things
Metabolism chemical reactions in the body’s cells that change food into energy
Stimulus/Stimuli a chemical or physical change in the environment that triggers some sort of behavioral change in a living organism
Homeostasis Examples Body temperature control, ocean temperature.
Glucose Balance pancreas, alpha and beta cells
Calcium Balance parathyroid glands
Water Balance pituitary gland, kidneys
What is negative feedback? Negative feedback is feedback that tends to stabilize a process by reducing its rate or output when its effects are too great.
What is positive feedback? Positive feedback occurs to increase the change of output. Contractions during childbirth.
What is a CER? What kind of scientific practice would it be a part of? CER or Claim, Evidence, Reasoning, is a writing format that helps students develop critical thinking skills in science class. It would be a part of forming a conclusion for an experiment.
