1.2 Science in Context
Researcher works for pesticide comp. says pesticide is safe , potential bias on study?
He might have a positive opinion as he works for the company and wants the results to be san in order to keep his jib.
add tells energy drink boosts energy, noter reviewing done, would you tell this to buying consumers?
Yes, they would be buying a non proven energy boost drink that is not shown to have that effect.
How does technology play a role in science?
discoveries in a field of science may lead to new technologies. those technologies help scientists in other fields ask new questions and gather data in new ways.
science in context to society
helps society environment, health, technology etc.
mathematical computational thinking
math calculations>ratios+ rates+ %+ unit conversions used to analyze and understand data , support claims and explanations
DNA
molecule essential for life
Scientific inquiry + engineering design very diff?
no, adoptions of SAME approach to scientific research.
Is theory considered absolute truth?
no, changes with eery new finding
What do scientists aim to be?
objective( other personal opinion might influence results)
What do peer reviewers look for?
oversights, unfair influences, fraud, or mistakes in techniques or reasoning.
Why is peer review important?
publishing peer-reviewed articles in scientific journals allows researchers to ++share ideas ,-test and evaluate each other work, -ensure accuracy -leads to other question sin the same field that can lead to more research> data> new findings.
Models
representations of objects or systems
What will understanding biology help you realize?
that we can predict the consequences of our actions and take an active role in directing our future and our planet's future
How is science limited?
they can only explain natural phenomena, doesn't incl moral viewpoints
Engaging in Argument from Evidence
using a reason/ evidence to show others why something is wrong by using evidence( analyzed data)
What is the relationship between science and society?
using science involves understanding its context in society and its limitations -sickness ,social + environmental research. - develop techn, build knowledge, satisfy curiosity, address social issues, inform policy, solve everyday problems.
Peer Review
when scientific papers are reviewed by anonymous, independent experts ? a\-> GOAL best quality article.
Why is testing ideas an imp. part of all science and engineering practices?
without testing you have no data to read, analyze and see if your hypothesis is true or not. Revised testing leads to gathering analyzed data .
How do scientists share their findings with the scientific community?
-colloborate in groups & communicate with other research groups. -by publishing articles that have undergone peer review
Constructing Explanations and Designing Solutions
After collecting data, analyzing and interpreting this data to be true to hypothesis_> now must create an explanation( how variables relate to each other with evidence)
How can peer review help scientist improve their work
Can show faulty info( data) or give more questions to make the research solider.
bias
a view that is personal, rather than scientific
What does the word theory apply to?
a well-tested explanation that puts together observations and hypotheses.It helps scientists to make accurate predictions about new situations
theory
an explanation that ties together many hypotheses and observations
What do scientific articles contain?
contain details about experimenting conditions, controls, data, analysis, and conclusions. (Articles for public shared in newsp, magazines. tv, blogs in less formal words) New data in scientific world leads to new hypotheses that will be independently supported or rejected by controlled experiments.
How are both curiosity and skepticism useful in Science
curiosity gives the will to find out why something is that way. Skepticism gives the will to find out of something IS what it looks like or not( find out truth)
What scientific attitudes help generate new ideas?
curiosity, skepticism, open-mindedness, and creativity
