Immediately after Lunch, Madeline runs a few short errands before heading to her favorite class. She walks east from the cafeteria to the Student Activities office. She then walks west to the bookstore. She leaves the bookstore and walks east to the library. She finally walks back west to reach the Physics classroom. Peace at last.

1. What is the total distance walked by Madeline?
2. What is the magnitude of Madeline's displacement?
3. What is the direction of Madeline's displacement?

Four students went out for pizza to celebrate after acing their physics final. All of them went directly from their high school to the nearby pizzeria, but they returned along the paths shown, taking different times. Values for the round-trip distances they traveled and the total times they took to walk their routes are given in the figures.

Rank the diplacement of each trip and seperately the distance

Pasta Bridge Lab

Objective:

• Determine the strength of a pasta bridge by finding the relationship between strength (number of marbles) and strands of pasta
• Compare bridge strength of two varieties of pasta

Presenting:

1. How you ran your lab (what was your procedure)
2. What you found:
   • Does your data confirm or deny your hypothesis? How so?
3. Anything else interesting you found

Pasta Bridge Lab

• What does the slope represent?
  • Can you write a "for each" statment?
• What does the intercept represent?
• How do the slope and/or intercept help support or refute your hypothesis?
  • Do other groups' data agree with yours?

Post Lab

• Discussion of results:
  • Interpret your results in the context of the experiment's objectives.
  • Explain any patterns or trends observed in the data
• Comparison with hypotheses:
  • Explicitly state whether your results support or refute your hypotheses.
  • Discuss possible reasons for any discrepancies.
• Sources of error and uncertainty:
  • Identify potential sources of experimental error.
  • Discuss how these might have affected your results.
  • Quantify uncertainties where possible.

Post Lab

• Conclusions:
  • Summarize the main findings of the experiment.
  • Relate these back to the original objectives and broader scientific principles.
  • Suggest improvements or future directions for the experiment.

Lab Notebooks

What is a Lab Notebook?

• A detailed, chronological record of a scientist's research activities, experiments, and observations.
• Documentation of the scientific process from intial ideas to final results and conclusions.

Why keep lab notebooks?

• Document Research
• Develop Ideas
• Organize Data
• Collaboration Tool
• Publication Support
• Troubleshooting
• Intellectual Property Protection
• Historical Record

Lab Notebooks can be Legal Documents

• Proof of invention in Patent Cases
• Intellectual Property Protection
• Admissibility in court - must be properly maintained
• Note: Often property of the instituation where the research was conducted (i.e. Property of Regeneron, or Property of Cornell University)

Remember

• Lab notebooks are most importantly scientific documentation
• They represent the scientific process and are record of your thinking
  • This means your ideas and conclusions and hypotheses can change based on new data

Lab Notebook

• Write in pen
• All mistakes get a single cross through
• Full Date (YYYY/MM/DD) at the beginning of each entry (for multiday labs date start of each day)
• Enter Lab Pages into table of contents

Lab Notebook - Pre Lab
