Q

What to do for research

A

Construct a research plan
Use key parts of your question to decide what’s to be researched
Network-talk to others that may know something about your question

17
Q

Research

A

An educated guess based on your observations and research that attempts to answer your question

18
Q

Control variable

A

Variables that must be held constant

19
Q

Control group

A

A variable a scientist purposefully keeps away from the IV so the scientist can see how something behaves before the experiment begins

20
Q

Procedure

A

Step by step description of how you conducted your experiment

21
Q

Important considerations

A

Test one thing at a time
Do several trials then average the most accurate results
Repeat experiment at least three times
Explain your procedure (variables)
List materials used
Use photos, diagrams, anything that’s helpful

22
Q

Collecting and organizing data

A

Collect data during an experiment
Organize your data as it grows so you can make sense of it
Often the best way to organize data is to use a data table
Correctly title and label your data table

23
Q

Showing results

A

Try to graph your results
Label and include units
Statistics are a good way to display data

24
Important steps
Summarize results in a few sentences, including key facts and explaining results where necessary If needed, state how your IV and DVD relate Summarize and evaluate your procedure Suggest changes
25
Graph checklist
``` Pick the right graph Title it IV in xaxis, DV in yaxis Label axes Choose proper scale Plot data accurately and clearly ```
26
Bar graph
Xgrid when you're making a single measurement, but you have multiple trials
27
Line graph

28
Time series graph
