Nature of Science
What is the process of repeating the experiment to draw valid conclusions?
Repetition
What do you do if your data does not support your hypothesis?
The data can lead to a new hypothesis and investigation.
What step of the scientific method does the scientist determine the materials, equipment, and the procedures to follow?
Planning the Experiment
What axis can you find the independent variable in a graph?
DRY MIX (X - AXIS)
What are the three main states of matter?
Solid, Liquid, and Gas
What is the process of another scientist redoing an experiment following the same procedures?
Replication
What is a scientific theory?
A well-tested explanation based on evidence and confirmed through observations and experimentation.
What step of the scientific method does the scientist share the results of the investigation through posters, presentations, or discussions?
Communicating results
What axis can you find the dependent variable in a graph?
What is a type of state that forms by super heated gases getting up charged up by particle motion?
Plasma
What is the variable that you purposely change during an experiment to test a cause-and-effect relationship?
Independent variable
What are three examples of scientific theories?
Form a Hypothesis
What can change with new evidence or data; a scientific law or a scientific theory?
a scientific theory
Which state of matter are the particles tightly packed together and vibrate very slowly and form at lower temperatures?
Solid
What is the variable that is measured in an experiment?
Dependent
What is a scientific law?
A pattern in nature that describes a statement based on repeated experimental observations.
What does a scientist do when conducting an experiment?
Observe and measure carefully and record accurate data. Look for important details!
Something that stays the same in an experiment!
What state of matter has no regular pattern and takes the shape of the container?
Gases
What are the three main points in doing research for an scientific investigation?
1. Verify the credibility of the source.
2. Use peer-reviewed scientific papers
3. Interview an expert (medical doctor or scientist)
What are three examples of scientific laws?
Laws of Motion, Law of Universal Gravitation, Law of Conservation of Mass and Energy, Law of Thermodynamics, Law of Dominance
What are the eight steps to the scientific method?
1. Ask a Question, 2. Do Background Research 3. Form a Hypothesis , 4. Plan the Experiment. 5. Conduct the experiment, 6. Analyze the Data, 7. Draw a Conclusion, 8. Communicate Results
What is the difference between a controlled experiment and a scientific investigation?
Investigation - Any experiment, observation, or survey that involves gathering data about a topic, but it doesn't have the strict controls of a controlled experiment.
From highest to lowest, what is the order of the states of matter in terms of particle motion?
Gas --> Liquid --> Solid
