What is Science?
The System of natural events and conditions.
What is Science?
If hypothesis is not testable it is Pseaudoscience.
Why should hypothesis be testable?
Scientific law describes what happens.
What is Scientific Law?
They organize data and use graphs to make sense of data.
How do scientists make sense of Data?
Models shows a structure of an object ,system or concept. A simulation uses models to see how they work.
Why do scientists use models and simulations?
Physical, Life, Earth science
What are the main areas in science?
You should check the source, science journals are the most credible source.
How can you evaluate quality of science information?
A sientific theory describes for what reason it happens.
What is a Scientific Theory?
Need tools to Conduct experiment, can also be used to make observations.
How are tools used in Science?
They are two types:
1. Scale model
2. Life size model
What are some type of Physical models?
- Careful obsevations
- Curiosity
- Creativity
-Logic
-Skepticism
-Objectivity
What are some characteristics of scientists?
Experiment,Observation,Hypothesis,Variables,Data
What are some parts that make up scientific investigations?
They mostly change when new evidence is found.
How do Scientific leads change?
They estimate measurments to see if data is reasonable.
Why do scientists sometimes estimate measurments?
Equations and graphs, chemical formulas and equations are some mathematical models.
What are some mathematical models?
1. Look at the empirical evidence
2. Think of tests you could run
3.Evaluate the explanation
How is scientific explanation evaluated?
They are used to answer the questions about the world.
How are scientific methods used?
Science affects the way we live our lives.
What does Science affect?
You can see if it is a linear relationship or a non-linear relationship.
What kind of patterns can be shown using graphs?
Conceptual models can be used to identify patterns and are parts of system.
What are some characteristics of conceptual models?
1. Can't be tested
2. Cant be proven right or wrong
What are 2 characteristics of pseudoscience?
- Defining a problem - Planning an investigation
-Forming a hypothesis -Making perdictions
- Identifying variables -Define conclusions
What are some scientific methods?
Anyone can contribute to science.
Who contributes to Science?
Measurments should be percise and accurate. Percision is the exactness of a measurment. A percise measurment is reapeatable and rialiable.
Why are accuracy and percision important?
Simulations are used to test designs in a controlled enviroment, and to test designs in a safe, less expensive way.
How are simulations used?
