With your group members, put all of your graphs from the lab on whiteboards.

1.Title page 2.Make these headings stand out (bold, italics, larger font, etc) 3.Units go in the column heading only for a data table. 4.Independent and dependent variables? 5.Historical context/motivation for doing the lab? 6.Type all lab reports 7.How did you decide on the number of trials to do? 8.How did you decide on the range of your independent variable? 9.No need to list all materials. 10.Don’t use second person. 11.Apparatus means equipment or materials. 12.Period: time it takes to complete one cycle

Whiteboard Requirements Names Big enough to read Meaningful color

Pendulum Lab Conclusions Mass Amplitude Length

Accuracy / Percent Error

Accuracy Calculation Examples

So what do experts say about a pendulum…? After many trials in different laboratories around the world, with much better equipment than we have, the equation for the period of a pendulum when swung with small amplitudes is

What is the shape of a graph of a square root function?

So how does the period you measured compared to what it should theoretically be? How can you explain the differences? You need to show this calculation and discuss your error in your lab report.

Types of Reasoning/Logic Inductive Reasoning – Starting from data and then recognizing general patterns, making generalizations, and drawing conclusions. – Examples: Development of theory of evolution Statistical sociology Our physics labs

Types of Reasoning/Logic Deductive Reasoning – Starting from principles, patterns, propositions or equations, then using these to draw conclusions or make predictions. – Examples: Discovery of a fossil fish with legs Mathematics Applying physics

Now you are going to analyze some data qualitatively. You will be working with the person sitting diagonally across from you at your table.
