The Nature of Science

This set is going to start to explain what science is to everyone who needs a head start or just needs to study for a midterm like me. (No pressure or anything. LOL!)

Terms

undefined, object
copy deck
data table
organizes information in columns and rows
inference
an explanation of why something happened
Why do scientists include many trials while performing experiments? What might happen if many trials are not performed?
They include many trials because there might have been an error in one of their previous experiments. Without many trials they might get the wrong result.
Controlled Variable
things that a scientist wants to remain the same, he must observe them as carefully as the dependent variables
What is a model? Why would the use of models be important in scientific experiments?
a sample of something that is too big, too small, or too complicated otherwise. They are important because they help us understand things we normally would not be able to understand.
Experiment
a way to test a hypothesis
Variable
a factor that can change in an experiment
The text refers to science as a "process." Explain.
That means science is a set of steps that you can use to help you find out more about something or to solve a problem.
How can we actually use science to help us understand problems in everyday life?
Science can help you solve everyday problems by giving your prior knowledge on, for example, weather patterns.
Technology
the use of knowledge learned by science; examples include computers, video games, and robots
observation
careful watching that can include measurements and descriptions and sketches or drawings of exactly what is seen
Hypothesis
a statement about a problem that can be tested
science
the process of trying to understand the world around you. A set of steps that can be followed to help find out about something or to solve a problem.
trials
the number of times an experiment is repeated
Is communication and important skill in science? Why?
Yes, scientists depend on each other to share what they have learned. It is important to communicate results because two scientists may have gotten two different results. That means one or both of the scientists are wrong and they will have to run more trials.
What are the steps in an experiment?
1. Identify the Problem 2. Form a Hypothesis 3. Design an Experiment to Test Your Hypothesis 4. Test Your Hypothesis/Do Experiment 5. Observe and Record 6. Analyze Results 7. Draw a Conclusion
Be prepares to discuss the difference between observation and inference.
Observation- uses senses, careful watching Inference- creating an explanation of your explanation
How do scientists communicate with each other?
They communicate with each other by recording everything they observe in a scientific journal. In their scientific journals they might express their ideas about what they are investigating, make a sketch of what they see, or explore different opinions on the subject. They also might make a data table and record information in that.
Independent Variable
This variable is the one that is changed by the scientists. In an experiment there is only one of these kind of variables.
How can we distinguish between science and technology?
Technology is not science. It is a use of knowledge learned THROUGH science.
Dependent Variable
changes in response to the change made to the independent variable
What is science?
the process of trying to understand the world around us. A set of steps that can be followed to help find out about something to solve a problem.
