Extra Credit T/F Review Test
You will be required to complete a scan-tron "No whining!"

The idea of forces is on the exam... Most importantly that they are vectors and behave as such.
The total FORCE= Net Force=(Fnet)=ma
Or simply Fnet=ma

There are only to possibilities when it comes to Fnet:
They add up to zero (equilibrium)
Or they don't and the object accelerates.
Here are some sample questions:

 How to Eliminate Choices:

•     What UNIT should the answer be in?  Especially for those questions with no numbers.  Look at the arrangements of the variables to find which choices are in the correct units (dimensional analysis)

•     Should the answer be larger or smaller than a given value in the problem? (increase/decrease/relationship problems)

•     For graphs, think about probable shapes and slopes.  Where the line goes to zero is often a good indicator of correct or incorrect choices.

•     For those questions that read “Which of the following…”  Be extremely careful of the word NOT and be sure to read ALL the choices before picking one.  Many mistakes are made when a student picks choice A after reading it and never even gets to B through E.

•     Predict the sign of your answer (+/–) to eliminate choices

•     Predict the possible directions (for currents, vectors, etc.) to eliminate choices

Happy Hollidays & winter solstice.
Thanks for those of you who gave gifts totally unnecessary.  As discussed we can not get lazy over the break.  So here are some things to keep you current and sharp.  You need to participate to learn physics.  If not I can't help you.
Read Ch.18.   As many times as it takes post on the blog questions and insights.
 here will be a reading quiz.

Objective:
 Devise a method to determine the relationship between length and time of a swing.
Create and interpret a parent graph for the data
Use this Graph PAPER only "CLICK HERE"

Things to think about.  

What shape is the graph?  Is it lnear?

• If your data does not agree with the class discussion the lab is easily redone at home find a bob and a length of string and measure the time for ten swings take the Avg.  It should be clear that it is not a linear relationship..
• Once you have identified the parent graph construct a daughter graph as discussed in class.
• Follow the rules for analyzing linear graphs find the slope and intercept.

AP POPPER LAB

Discussion

Print this out and bring to class on Friday

Class Policy

If you have trouble print it in the library or computer lab.

Explain and Discuss the trends you see.

Writing an Abstract

Summarizing the lab report

Summarize each major section of the lab report--Introduction, Methods, Results, Discussion, and Conclusion--in 1 sentence each (two if a section is complex). Then string the summaries together in a block paragraph in the order the sections come in the final report.

More Help:

You can think of the Abstract as a miniature version of the whole lab report. Read each section of the report and boil it down to a sentence. This means that you need to determine the most important information in each section.

• Here are some suggestions for what to include in each sentence of the Abstract:
  • Introduction: research problem of the lab; hypothesis
  • Methods: a quick description of the procedure
  • Results: statement of the overall findings
  • Discussion: judgment about hypothesis; solution for problem
  • Conclusion: what you learned from doing the lab
• Put all these sentences together into one paragraph with the heading "Abstract."

Things That?

• students will be able to identify the components of a scientific observation and contrast with non scientific observations
• replace transform non scientific observations and make them scientific.
• Recognize the difference between qualitative,quantitative, subjective and objective and what characteristics an observation has
• Investigate and create operational definitions based on observations
• Use observations to develop the need and understand the importance of measurement
• Marketing (ratemymullet.com)
• use observations to organize things in a clear and consistent manner
• use observations to construct hypothesis
• identify strategies for looking for organization
• binomial searching algorithm 
• use and understand a graphic organizer (T-Chart)
• Use the T chart 
• to make observations as to trends
• extrapolate (evolution)
• interpolate (missing link)
• summarize

Several Questions:
Do not look up the answer it is useless in this exercise. 
Write down your observations of the characteristics of fruits and vegetables use that to define them and determine the difference!

You should make a things that chart to answer your questions.

What is the difference between a fruit and a vegetable?  So what is a Banana?


What is a duck billed platypus?

LABORATORY AND EXPERIMENTAL SITUATIONS
These objectives overlay the content objectives, and are assessed in the context of those objectives.
1. Design experiments
Students should understand the process of designing experiments, so they can:

          a) Describe the purpose of an experiment or a problem to be investigated.

          b) Identify equipment needed and describe how it is to be used.

          c) Draw a diagram or provide a description of an experimental setup.

          d) Describe procedures to be used, including controls and measurements to be taken.

2. Observe and measure real phenomena
Students should be able to make relevant observations, and be able to take measurements with a variety of instruments (cannot be assessed via paper-and-pencil examinations).
