Components of the scientific method.
*Question- what problem would you like to investigate?
*Background research- look at info ( 3 different sources)
*Hypothesis- an educated guess about what you think will happen. The comparison of the IV and DV to find the relationship between them.
_design_
*Observation- where you put data and diagrams. tables are completed as you're doing your testing.
*Analyze Data/Interpretations- where you putt your graphs
Conclusion- What were the results of the lab? Did the data support your hypothesis? Use SPECIFIC examples from data to justify whether you were correct/ incorrect with your hypothesis*
Analyze any errors in the inquiry. Identify ways to reduce errors, what could have been done to improve lab accuracy?
YOU MUST INCLUDE SPECIFIC REFERENCE DATA IN THE CONCLUSION!! BE SPECIFIC. Conclusion would also include at least two areas of further study.

* x axis is IV, y axis is DV
*must include units of measurement
*appropriate spacing
* out of 7
