The two blocks are identical and both are at rest. A student comparing the normal force exerted on the block by the surface in the two cases states:

“Since both blocks are identical, I think the normal forces are the same because in each case the normal force will be equal to the weight.”

What, if anything, is wrong with this contention? If something is wrong, identify it and explain how to correct it. If this contention is correct, explain why.

Test Corrections

  1. Determine correct answer for incorrect questions
    • For FRQ you need to correct the entire part (i.e. part (a)) if you lost any points
    • No you cannot see what you put before - start from scratch
  2. For MC questions you must provide a justification
    • Start with a fact of physics "slope of VT is acceleration" or "area of VT is displacement"
    • Draw a diagram to help (i.e. draw a VT graph)
    • Try to use a claim evidence reasoning format to write your justification
  3. Finally, compare your new, correct answers to your test and determine if your mistake was one of the 4 C's: clueless, careless, conceptual, or calculation.

Test Corrections Summary

  1. Look for trends about what your test performance:
    • Were there certain types of questions you missed?
    • Do you need to review/relearn/learn some material that was tested?
      • What learning mastery standard do you think that material aligns with?
    • Was there a common mistake you made?
    • Summarize
  2. Meet with Mr. Porter to discuss the trends before you turn in your corrections.

Buggy Lab

Objective:

  • Determine if your toy buggy moves in a consistent manner by developing a relationship between position and time.
  • Use time as your independent variable

📓 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

  • Title and objective of the experiment:

    • Write a clear, concise title for each experiment.
    • State the main objective or purpose of the experiment in 1-2 sentences.

  • *Theoretical background:

    • Briefly explain the relevant scientific principles.
    • Include key equations or concepts that will be tested or applied.

  • Hypotheses:

    • State your predictions about the experiment's outcome.
    • Base these on your understanding of the theory.

Lab Notebook - Pre Lab

  • Materials and equipment list:
    • Provide a detailed list of all materials and equipment used.
    • Include model numbers and specifications where relevant.
  • Experimental procedure outline:
    • Write a step-by-step outline of the planned procedure.
    • Be specific enough that someone could replicate your experiment.

During the Experiment

  • Raw data in tables with units:
    • Create neat, organized tables for all numerical data.
    • Always include units and uncertainty estimates.
    • Label columns clearly and use consistent significant figures.
  • Observations and qualitative notes:
    • Record all relevant observations, even if they seem unimportant.
    • Note any unexpected occurrences or anomalies.
  • Any changes to the planned procedure:
    • Document any deviations from the original procedure.
    • Explain why changes were made and how they might affect results.
  • Sketches or diagrams of experimental setup:
    • Include clear, labeled diagrams of your experimental setup.
    • Add dimensions and important details to aid in replication.

Post Lab

  • Data analysis and calculations:
    • Show all steps in your calculations, including formulas used.
    • Explain your reasoning for each step of the analysis.
  • Graphs and charts:
    • Create neat, properly labeled graphs and charts.
    • Include titles, axis labels with units, and legends where appropriate.

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.

Buggy Lab

Objective:

  • Determine if your toy buggy moves in a consistent manner by developing a relationship between position and time.
  • Use time as your independent variable

Identical treasure chests (shown from above) each have two forces acting on them. All chests start at rest. ![center](image-11.png) **Rank the speed of the treasure chest after 2 seconds.** --- The forces exerted on an object at a particular instant are represented in the free-body diagram. The magnitude of each force is drawn to scale. A student claims that the vector sum of the forces on the object is equal to zero. Is the student's claim valid? Why or why not? ![center](image-12.png) --- The free-body diagram shows three forces exerted on an object. Each square is 1 N by 1 N. What is the magnitude of the vector sum of the forces exerted on the object? ![center](image-13.png)

ANSWER IS C
