5th grade unit 1 lesson 3 Flashcards
What makes a good scientific question?
one that can be answered bh an investagation
A scientific investigation always begins with?
question
What are scientific methods?
are ways scientists perform investagations
All scientific methods use ?
1logic
2reasoning
The method a scientist uses depends on the question. What are 3 methods
1experiements
2reapeated observations
3using models
WHat are experiments?
scientists control all of the conditionsbof the investagation
How do you use models when investigating a question?
they use models when they cannot experiment on the real thing
How do you use repeated observations when investigating a question
scientists use reapated observation to study procces in nature which cannot be controlled be contolrd
How do scientists draw conclusions after they have used a scientific method?
they will have results they can draw conclusions with
p26-27 explain more about when observation is used as a scientific method
when things are just to hard to reach or contorl old faithful whales
p28-29 why do scientists use models?
when scientists cannot experiement with the real thing, they use models
what are the different ways models are made?
1phsical model
2program computer simulation models
3diagrams&flow charts

check ot twice
analyze your results
What do ou do after you analyze your data/you have your results?
make a data table and draw comclusions and evaluate your hypothisis
What are ways to communicate the data you collected after you completed a science investigation.
