Using one or more of your 5 senses to gather information about the world
2. 5 senses
see, hear, taste, smell, feel
3. Examples of observations
dog bark, smelling smoke, counting 12 green seeds
4. data
information collected through observations; evidence
5. infer
interpret an observation
6. examples of inferences
dog barks, you infer someone is at the door; baby cries- hungry, wet, hurt
7. classify
put things together in groups based on characteristic that they share to make it easier to study
8. how do we classify shapes
size, shape, color, how it's used
9. model
smaller version of an object.  makes it easier for scientists to study.
10. examples of models
drawings, physical models
11. why do scientists communicate with eachother?
• share results
• share information
• share opinions
12. what is science inquiry?
it is thinking like a scientist:  being inquisitive, asking why, and searching for answers
13. What is the standard system of measurement used by scientists around the world?
International System of Units or SI
14. why are si units easy to use
they are based on units of 10
15. What do scientists use to measure length?
meter (m)
16. What two instruments are used by scientists to measure length?
metric rulers and meter sticks
17. What are some common SI prefixes?
• kilo- k
• hecto-h
• deka-da
• deci- d
• centi- c
• milli- m
18. What is the volume of a liquid?
the amount fo space the liquid takes up
19. What is the unit of measure scientists use to measure liquid volume?
Liter (L)
20. What instrument is used to measure liquid volume?
21. mass
the amount of matter in an object (or weight)

a balance is used to measure mass
22. gram
unit of measure used to measure mass
23. Larger masses are measured in. . .
Kilograms (kg)
24. Celcius
used to measure the temperature of something
25. water freezes at
0 Celcius
26. water boils at. . .
100 Celcius
27. unit used to measure time. . .
seconds
28. how do scientists share the data they gather?
• data table
• pictures
• diagrams
• models
• graphs
29. Steps to a scientific investigation:
• 1.  pose a question
• 2. create a hypothesis
• 3. materials
• 4. procedure
• 5. observations
• 6. results
• 7. conclusion
30. the factor that you change in an experiment is called...
independent or manipulated variable
31. the factor that chages the result of the independent variable
responding or dependent variable
32. controlled experiment
an experiment in which all factors except for one are kept constant
33. operational definition
a statement that describes how a particular variable is to be measured or how a term is to be defined.
34. data
the observations and measurements you make in an experiment
35. conclusion
a statement that sums up what you have learned from an experiment.
36. Where do scientists record their measurements and data
data table
37. bar graph
used to display data in a number of separate, or distinct, categories
38. line graph
used to show how one variable (responding variable) changes in response to another variable (control)
39. a graph or chart that shows a category compared to 100%
• pie chart
• circle graph
40. A question or purpose to guide your activity
problem, question, or objective
41. The background information to help answer the problem question
research

hypothesis
43. list of items used ot conduct experiment
materials
