Watch:

This may change your life, or not.

When We Get Back
In your Lab notebook
Objective:

INTERPRETING Slope & Intercept

Graphing and Math Skills

Please attempt all questions and write down specific questions for those that you find difficult or confusing.

NOT AS EASY AS PIE

Quest   Wednesday 12/20/17

DUE MONDAY  12/18/17 "not as Easy as Pie"

Complete the Parent and Daughter graph demonstrated in class using Excel 

Key Terms:

Graphical analysis, Linear Relationship, proportional, Slope, Intercept, Percent error, accuracy, precision, Coefficient of regression

3 SKILLS TAUGHT 3

"GOOD GRAPHING"

Write the equation of a line in slope intercept form.

What is the formula for slope?

What is the formula for the slope of your graph?

What are the units of your slope?

What is the ideal value for this relationship?

What is y-intercept?

What was your y-intercept from your graph?

(4)ANALYSIS (4)

What does the intercept tell you about your lab?  What should your intercept have been? Explain.

What is the formula for % error?

What does the slope of your graph represent?

What was your % error in the lab?

                If the error is above ±5 % give a possible reason(s) that agree(s) with the error.

Look at the R² value, this is known as the coefficient of regression.  It is a number describing how well your points follow a linear relationship.  The closer it is to 1 indicates linearity.

                Does the R² describe the Precision or the Accuracy?

(5)Interpretation (5)

Using the above information write a statement citing evidence about both the precision and accuracy of your lab.  What needs to be done to improve the results in future labs?  Is there a way you can verify this?

Straightening Things Out...

• HW:Linearize your Graph!!!
• The issue is how to write a function for something that is not linear.
• Solution make it look Linear w/ Excel
• How:
• Watch Video Below

NOT AS EASY AS PI

Experimentally determine a mathematical model that relates the time and the length of a pendulum.

• Why did you use 10 swings? 
• How does this affect the accuracy?
• How does this affect your precision? 
• What would you need to do to increase the precision?
• Calculate the precision using your graph?
• What id the dependent variable? Explain.
• What axis does the independent variable?
• What is the coefficient of regression?
• What does this tell you about your relationship?
• Does your graph (model) support a linear relationship?
• What are the 2 ways you can check/verify

Straitening Things Out:

• Parent Graphs
• Copy this Chart in Your Notebook/
• 

EASY AS PIE

ALL HONORS PHYSICS CLASSES

COMPLETE ALL measurements of Circumference and Diameter
Graph C vs. Diameter using the good graph post and note as a guideline
y=C  x=D    small thing-small side  Big thing big side

• DUE MONDAY
• COMPLETED GRAPH
• BLOF
• POINTS FOR SLOPE IDENTIFIED
• SLOPE CALCULATION

GRAPHICAL ANALYSIS

Make an Entry in your Notebook with the title above.

Things That Measure?

Create a list a of words you associate with measurement.

Organize the words in to categories and determine what each category has in common.

Crate a chart of fundamental ideas.

Define, describe, and differentiate the key ideas terms.

How Science Works

If you have been wondering what we were doing...  Did you actually try using what we were doing to answer the question?

• What is Physics Class about?

• What is science?  

• What are the goals?  

• How is it done?
•  
• Testing ideas with evidence from the natural world is at the core of science.
• Scientific testing involves figuring out what we would expect to observe if an idea were correct and comparing that expectation to what we actually observe.
• Scientific arguments are built from an idea and the evidence relevant to that idea.
• Scientific arguments can be built in any order. Sometimes a scientific idea precedes any evidence relevant to it, and other times the evidence helps inspire the idea.

DAY 9:

THINGS THAT cont.

• The Mind Map is the external mirror of your own radiant or natural thinking facilitated by a powerful graphic process, which provides the universal key to unlock the dynamic potential of the brain.The five essential characteristics of Mind Mapping:

• • The main idea, subject or focus is crystallized in a central image.
  • The main themes radiate from the central image as 'branches'.
  • The branches comprise a key image or key word drawn or printed on its associated line.
  • Topics of lesser importance are represented as 'twigs' of the relevant branch.
  • The branches form a connected nodal structure.
