Scientific Method
This is a possible explanation or prediction that can be tested.
What is a hypothesis?
This is the variable that the scientist changes.
What is the independent variable?
This means maintaining a stable internal environment.
What is homeostasis?
Living things are made of these.
What are cells?
A group of organisms living together is called this.
What is a population?
This is what scientists do when they notice something and use their senses to gather information.
What is an observation?
This is the variable that the scientist measures.
What is the dependent variable?
This is the normal value that the body tries to maintain.
What is a set point?
Living things react to changes in their environment through these two related processes.
What are stimulus and response?
These are sections of DNA that contain genetic information.
What are genes?
This part of an experiment is used for comparison and does not receive the treatment.
What is the control group?
These are the factors that are kept the same during an experiment.
What are constants?
Your notes give this temperature as an example of a human body's set point.
What is 98.6°F?
Living things need and use this.
What is energy?
This occurs when populations change over generations.
What is evolution?
This is the step where scientists explain whether their hypothesis was supported using their data.
What is the conclusion?
This type of data uses numbers and measurements.
What is quantitative data?
This type of feedback helps return a system toward its normal condition.
What is negative feedback?
Living things do this to produce offspring.
What is reproduction?
This process can cause helpful traits to become more common in a population.
What is natural selection?
Scientists share their findings through these, including journals and presentations.
What is communication?
This type of data uses descriptions rather than numerical measurements.
What is qualitative data?
This type of feedback continues to increase the original change. Your notes give childbirth as an example.
What is positive feedback?
Your notes list this as the genetic material that is passed from parents to offspring.
What is DNA?
This is the study of interactions between organisms and their environment.
What is ecology?
