What is another word for hypothesis?
evidence based on an observation
proposed explanation or answer for a question
prediction about what will happen based on an observation
investigation based on a question
A Scientific Theory is a hypothesis
that is a good idea but there isn't good evidence for the theory yet
that has been tested many times by different people
that has always been supported and never been rejected.
that is supported by MULTIPLE lines of evidence
that is extremely unlikely to be rejected in the future.
What is Science?
A specific way of studying the world called the scientific method.
the work scientists do.
The one and only way to study of the world
A body of knowledge accumulated by the scientific method.
Which domain is capable of living in extreme environments like hot springs, geysers, or very salty waters?
Bacteria
Archaea
Eukarya
What are the 3 domains?
Bacteria
Eukaryotes
Archaea
Viruses
Which of the following lists the three domains accepted by most scientists?
Bacteria, Protista, and Eukarya
Bacteria, Fungi, and Protista
Eukaryotes, Archaea, and Bacteria
Archaea, Prokarytoe, and Eukaryote
In science, a theory, such as the Theory of the Unity of Life is_________.
A great idea, but mostly untested or unproven.
A speculation or prediction about the natural world, based on general knowledge of a field an observation.
a general set of principles, not yet supported by evidence, that scientists can use to make hypotheses.
a hypothesis that has been tested many times, by different scientists and that has never been rejected or falsified and is therefore unlikely to ever be rejected or falsified. Scientific Theories like evolution also have a large body of supporting evidence.
What is the Scientific Theory of the Unity of Life is about?
This scientific theory says that all life is related and traces its ancestry to a universal ancestor. This theory is well supported with multiple lines of evidence such as that all life is made from cells.
This scientific theory speculates that possibly all life is related even though there is no evidence for this (yet).
This scientific theory theorizes that all life could get along if people tried a little harder.
All life is united!
