What do we use to make qualitative observations?
five senses
What does hypothesis mean?
Educated guess or answer to testable question

What part of the scientific method do you use to data tables?
Collect and study data
What do we use to make quantitative observations?
Numbers and measurements
What does it mean to interpret something?
To explain what something means.
What are the three types of graphs that we discussed in class.
Bar circle and line
Define independent variable.
The variable that we change as scientists
Scientists use their five senses and numbers/ measurements during this time.
Observing
Make a qualitative observation about my room.
What does analyze mean?
To notice patterns or relationships
The Y axis goes (left or right) or (up and down).
The X axis goes (left or right) or (up and down).
y= up and down
x = left and right
Define controlled variable
The variables that we keep the same.
This part of the scientific method is where the scientist discusses their findings, errors, and what can be done to improve the experiment.
Conclusion
