7th Science - NOS 4 What is Science? Flashcards
What is the investigation and exploration of natural events and of the new information that results from those investigations?
science
What are the three major categories of Science?
- Life Science
- Earth Science
- Physical Science
What is the study of all living things?
Life Science
What is the study of chemistry and physics?
Physical Science
What is the study of the earth including its landforms, rocks, soil, and forces that shape it’s surface?
Earth Science
What is the process that uses a variety of skills and tools to answer questions or to test ideas about the natural world?
scientific inquiry
What are the steps in the scientific inquiry?
- Ask questions
- Gather information through research
- Form a hypothesis
- Test the hypothesis
- Analyze data
- Draw conclusions
What is using one or more of your senses to gather information and take note of what occurs?
observation
What is a logical explanation of an observation that is drawn from prior knowledge or experience?
inference
What is the most important thing when gather information through research?
Using reliable sources
What is a possible explanation about an observation that can be tested by scientific investigations?
hypothesis
In what form is a hypothesis made?
Always in the form of a statement
What is a statement of what will happen next in a sequence of events?
Prediction - educated guess
Name some ways to test a hypothesis.
- design an experiment
- make a model
- gather and evaluate evidence
- collect data/record observations
What is a quantity that can have more than a single value? (All the factors that will affect the thing you are studying.)
Variable
What are the four types of variables?
- Dependent Variable
- Independent Variable
- Constant
- Control
What changes according to the changes of the independent variable; the thing you are testing for; outcome?
Dependent Variable
What is the variable that is changed to test the effect on the dependent variable; the thing that your comparing?
Independent Variable
What are all the factors that do not change when other things change?
Constant
What is the standard by which the test results can be compared?
Control
What are you doing after analyzing data when you are deciding if your results support or do not support your hypothesis?
Draw conclusions
Before publishing, scientists investigations go through what?
Peer Review
Do scientists need to be objective in reporting results and performing investigations?
Yes, otherwise there would be a bias
What is an explanation of things or events based on knowledge gained from many observations and investigations which CAN be modified?
scientific theory
What is a statement about what happens in nature and that seems to be true all the time and CANNOT be disproven?
scientific law
What can be used to explain a law?
a scientific theory
What is the amount of space occupied by an object?
Volume
How would you determine volume?
Volume=Length x Width x Height
What is the measurement of quantity of matter in an object.?
Mass
What is the mass per unit volume of a material?
Density
How would you determine density?
Density=Mass/Volume
What is the application of scientific knowledge to benefit people?
Technology
Name the types of technology.
- Objects (ink pen, calculator)
- Methods or techniques (how books are printed)
- Knowledge or skills (use of a complex machine)
- Systems (airline industry)
What is any technological application using living things or living systems?
Biotechnology
