Section 1
what is the final step in scientific methodology?
drawing conclusions
What is one thing that both scientists and engineers do during their process?
- develop & use models
- use mathematics & computational thinking
- construct explanations & design solutions
- engage in argument from evidence
the basic (and smallest) unit of all living things
cell
the first step in a scientific investigation is writing a hypothesis
false
observing & asking questions
this group in a controlled experiment is the one actually being tested
what is an experimental group?
these are the two types of data
this part of the scientific process occurs after the scientific paper has been written and ensures that the highest quality of research is being published
peer review
which field of biology is highly controversial for its ability to "edit" and "rewrite" the genetic code?
biotechnology
the motto of our class is "Biology never changes"
false
the universal genetic code that allows traits to be passed from parent to offspring
DNA
deoxyribonucleic acid
along with the fact that science organizes information orderly and uses evidence to give explanations, how else is science different from other subjects?
Science only deals with the natural world
What are the three possible outcomes of a hypothesis after an experiment?
support, refute, or revise
Which pair of crosscutting concepts are BEST exemplified when birds fly south when winter comes to the United States, and north when spring arrives?
patterns
cause and effect
science occurs in a vacuum and is not influenced by (or does not influence) society at all
False
when designing a controlled experiment, what is being directly manipulated by researchers?
the independent variable
if a scientist is watching wild animals and recording their behavior, what step of scientific methodology are they practicing?
observations (observing & asking questions)
these four scientific attitudes can be partly responsible for developing new scientific experiments or investigations
when your body responds to a stimulus (like your brain telling you that you are hungry), it is trying to maintain this, which means narrow set of conditions ideal for life
homeostasis
a milliliter and a cubic centimeter measure the same things
true
the combination of chemical reactions every living thing manages as it carries out its life processes
metabolism
this tested and reliable explanation of scientific events is not permanent, but can be revised as more scientific information comes to light
theory
From p. 20 in the text, which step in engineering design comes before "Redesign[ing] a prototype based on performance data"
"Design & Create a prototype/model; test it to gather and evaluate performance data"
no
All scientists use the same measuring system when performing investigations
true
the metric system
this personal (instead of scientific) point of view can be fore or against an idea, and can make scientists less objective
what is bias
