Chapter 1 Vocabulary Science and Experimentation Terms
KWL Charts The first column is what you know about a word. • Maybe it is a definition. • Maybe it is something you’ve heard someone say before. • Try to avoid “IDK” and “Nothing” unless you really have too. A total guess that is wrong is better than nothing.
KWL Charts The second column is what you want to know about a word. • Ask questions here. • Good examples: • “How is Myth Busters science?” • “How is a hypothesis different from a theory?” • “How is this word different in science than in normal use?” • Bad Examples of answers here: • “The definition” • “IDK”
KWL Charts The last column is what you learned about the word. • Maybe it is a definition. • Something cool you didn’t know before.
Directions Fill out the first column of your KWL chart BY YOURSELF. There should be no talking while you do this part. If you finish early, you can start to fill out the second column while you wait for the class to catch up.
Directions On a separate piece of paper, take notes on the words. These will help you to finish column 2 and column 3. Details on meanings Words
Science • Systematic enterprise • Builds and organizes knowledge • Uses testable explanations and predictions • Rational • Reliable
Scientific Inquiry • A way to investigate and propose explanations for observations
Model • A physical, conceptual, or mathematical representation of a real phenomenon. • Used to explain and predict the behavior of real objects or systems.
Hypothesis A tentative explanation for an observation, phenomenon, or scientific problem that can be tested by further
Scientific Theory Scientific theories are the most reliable, rigorous, and comprehensive form of scientific knowledge A theory is not the same as a hypothesis, as a theory is a 'proven' hypothesis, that, in other words, has never been disproved through experiment, and has a basis in fact.
Scientific Law Express a fundamental principal of science Confirmed and broadly agreed upon Differ from theories in that laws don’t explain a phenomenon. Many are mathematical formulas
Observing Noticing and perceiving with our senses
Predicting In science, a prediction is a rigorous, often quantitative, statement, forecasting what will happen under specific conditions
Inferring Deduce or conclude (information) from evidence and reasoning rather than from explicit statements.
Communicating The ability to communicate effectively through speaking as well as writing
Controlled Experiment An experiment witha control group and an experimental group. After your experiment, you compare the two to see what effect your experiment had.
Manipulated Variable A variable that the scientist changes. Something you can control.
Responding Variable Result of the experiment
Reproducibility Reproducibility is the ability of an entire experiment or study to be done over with the same results, either by the researcher or by someone else working independently.
Accuracy How close a measurement is to the correct answer.
Precision Repeated measurements give the same result
Estimate Finding an approximate answer
