Reasons for conducting scientific investigations.
|
identify potential problems and to create solutions to those problems before they actually occur
|
|
Results of Investigations
|
New innovations may arise that not only solve a problem but may lead to the creation of consumer products that provide a greater standard of living.
|
|
Hypothesis
|
an explanation formulated to answer the questions being investigated, has at its essence a statement that can be tested.
|
|
Steps for forming a hypothesis
|
1.Identify the problem: Observe and determine the problem to be investigated.
2. Ask questions: ask questions and attempt to formulate a solution the problem 3. Formulate a hypothesis: formulate explanations to answer questions. This involves making predictions that follow from the initial statement of the problem. |
|
Testing a hypothesis
|
systematically identifying the variables involved, followed by creating a plan of action that involves observation and experimentation.
|
|
Scientific Method (Argument) Steps
|
1. Problem identification
2. Question asking 3. Hypothesis development 4. Data collection and experimentation 5. Analysis 6. Conclusion |
|
Data Collection
|
collect data throughout the scientific process to test the hypothesis or predictions in a controlled environment. Steps: Observation, Measurement, Samples, Organization
|
|
Experimentation
|
Involves comparing a control group and an experimental group. The two groups both equally represent a population. The difference is that the experimental group is different from the control group based on one variable.
|
|
Analysis
|
Scientists must analyze data collected during experimentation. The researchers must determine if the data is reliable and whether or not it supports the hypothesis.
|
|
Conclusion
|
The purpose of the scientific process is to develop a conclusion. Scientists produce models to represent the explanations supported by the data.
|
|
Two reasons why scientific research is dependent on technology
|
advanced technology I used to generate graphs, and provide numerical models to describe mathematical relationships.
|
|
Why is mathematics necessary for scientific research
|
if mathematics was not used, the best scientific descriptions would be purely qualitative in nature. No modern conveniences could exist without mathematics, because creation of all technology is ultimately mathematical.
|
|
Communication and its relation to mathematics and technology
|
The sharing of information within corporate entities has been revolutionized with modern technology and is experiencing continual growth of intranet capabilities.
|
|
Paradigm Shift
|
alternative explanations that are in direct opposition to previous understandings
|
|
Deductive Reasoning
|
a method whereby conclusions follow from general principles.
|
|
Inductive Reasoning
|
a method of arriving at general principles from specific facts.
|
|
Changes to Theories
|
scientific theories have been revised throughout history as new methods and techniques of investigation have become available.
