Celya W. Period 4 Unit 1
Transcript of Celya W. Period 4 Unit 1
Scientific explanations are based on empirical evidence. Therefore, they can be tested. Politics and science often do correspond. Political support can not only help funding for research, but also help scientists work together. Scientific discoveries have helped us make lifesaving discoveries, learn to protect resources, and make new rules and laws. Many times, it affects not only us, but other nations as well. Period 4 Celya W. Some things that make up Scientific investigations are:
Data Some graphs scientists use are:
(If a graph's data forms a relationship resembling a straight line, it is a linear graph. if not, it is a nonlinear graph.) Scientists often make sense of their data by making a table with two columns: Independent variables and Dependents variables. They then look for any patterns or trends once organizing it into graphs. Scientists plan their investigations to address a specific problem or question. Their goal is to come up with a scientific explanation. Each problem or question is unique and so requires a unique method and the proper tools. Remember that science does not claim to prove anything.
Science attempts to provide an explanation that agrees with the results of observation and testing. At times, as new evidence is discovered, scientists may find that an earlier theory is incorrect or incomplete.
Good scientific theories often get modified but are rarely rejected. Scientists usually do these two things:
Field work- where you observe whats outside
and Lab work- where you test things under controlled variables. An experiment is an organized procedure to study something under controlled conditions.
Observation is the process of obtaining information Hypothesis - A testable idea or explanation that leads to scientific investigation
Model - representation of an object or system.
Experiment - organized procedure to study something under controlled conditions.
Observation - the process of obtaining information by using the senses.
Independent variable - the factor that is deliberately manipulated.
A dependent variable changes as a result of manipulation of one or more independent variables.
Data - information gathered by observation or experimentation that can be used in calculating or reasoning. Good resources include Scientific Journals, books written by scientists, and government and academic websites. Scientists use many different kinds of models.Some are physical models, such as maps and globes.Others are mathematical models, including equations and simulations of movement Science is influenced by societal needs and economics.
If society sees no value in certain research, scientists may not get funding for the research.
People may not buy or use new technologies if they do not think they are useful. Lesson 1 LESSON 2 Lesson 3
