The goal of science
|
To investigate & understand nature, to explain events in nature, and to use those explanations to make useful predictions.
|
|
|
Science is different from other human endeavors like art & history mainly because it relies on:
|
Testing explanations
|
|
|
Name 3 things that make science different from other human endeavors like art, and history.
|
1. Science deals only with natural world.
2. collect & organize info orderly, looking for patterns. 3. Scientists propose explanations that can be tested by esamining evidence. |
|
|
In other words, science is an ________________ way of using _______________________ to learn about the ________________ world.
|
organize, evidence, natural
|
|
|
Science starts with _________________.
|
Observation.
|
|
|
Observation involves using one or more of the __________, _______, ________, _______. ______ and sometimes ________,. to gather info.
|
senses, sight, hearing, touch, smell, & sometimes taste
|
|
|
Observations can be classified into ____ types, please name them:
|
2 types: quantitative & qualitative
|
|
|
What do quantitative observations involve?
|
numbers, counting or measuring.
|
|
|
What do qualitative observations involve?
|
characteristics that cannot be measure or counted, like color or texture.
|
|
|
Does an observation alone mean a lot in science? Why or why not?
|
No, because the goal is to understand WHAT was observed.
|
|
|
So what do scientists usually do to understand observations?
|
They follow observations with INFERENCES.
|
|
|
What is an INFERENCE?
|
A logical interpretation based on prior knowledge & experience.
|
|
|
What is an example of an inference?
|
Researchers might sample water from a reservoir at different areas and if all the samples are clean they INFER that all the water is safe to drink.
|
|
|
What is a HYPOTHESIS?
|
A possible explanation for a set of observations or an answer to a scientific quesiton.
|
|
|
Can a hypothesis be stated about any topic or idea in everyday settings?
|
Yes, but in science, a hypthesis is useful ONLY if it can be tested.
|
|
|
Science is the _____________ body of ________________ from previous _____________.
|
accumulated, knowledge, research.
|
|
|
The info gathered by observations is __________ or _______.
|
evidence or data.
|
|
|
Observation is meaningless without an __________________, or a logical ____________
|
inference, interpretation.
|
|
|
The test of a HYPOTHESIS may provide evidence that either, __________ it, _______ it, is _______ (unclear), or __ __________ ___ ____________.
|
supports it, rejects it,
is ambiguous (unclear), or all results are valuable. |
|
|
Hypotheses may arise from prior __________, logical ________, or _____________ guesses.
|
knowledge, logical inferences, or imaginative guesses.
|
|
|
How is a hypothesis most often tested?
|
Through a controlled experiment.
|
|
|
How do scientists develop hyptheses?
|
they often work in teams, combining imagination & logic to develop and test hypotheses.
|
|
|
If a HYPOTHESIS is tested and is proven wrong, does it still have value in science? If so, why?
|
Yes, because it helps researchers advance scientific knowledge, regardless of the outcome of the HYPOTHESIS.
|
|
|
For scientists, science is an __________ process, not the discovery of an __________, absolute truth.
|
ongoing process,
unchanging. |
|
|
Are scientific findings set in stone and unchangeable once they are discovered?
|
No, scientific findings are always subject to change as new evidence is developed.
|
|
|
Does science have limits?
|
Yes, it cannot give you opinions about stuff.
|
|
|
What are some ways that people use science every day?
|
Problem solving, like if a car does not start, question and test if it is out of gas, or perhaps the battery is dead,
|
|
|
Science is used for biology and what are some other issues that science deals with also?
|
Health and Disease
Genetic testing, Cloning Stem cells, Global Warming, Environment, etc.` |
