BIG PICTURE 1 WEEK 1-3: UNIT LEARNING OUTCOMES (ULO)

  • Upon completion of this unit, students will be able to:

    • (a) Perform conversions of units.

    • (b) Demonstrate an understanding of the concepts of chemical safety.

Big Picture in Focus: ULO1a: Perform Conversion of Units
Metalanguage

  • Dimension: Physical quantities that can be measured (e.g. length, volume).

  • Units: Arbitrary names that correlate to particular dimensions to make the measurement relative to an agreed-upon definition (e.g. meter, liter).

  • Conversion Factor: A number used to change one set of units to another, by multiplying or dividing.

  • Scientific Notation: A way of expressing numbers that are too large or too small to be conveniently written in decimal form.

Essential Knowledge

  • Standards and Measurement: Crucial for calculations, metrics rely on commonly understood definitions to ensure uniform communication.

Reading a Measuring Device

  1. Digital Devices: Record precise readings directly as displayed (e.g., mass shown in grams).

  2. Non-Digital Devices: Use rules or scales that may require estimation beyond certain known values.

Significant Figures

  • Not all figures in a measurement are significant; certain rules apply when rounding and using scientific notation:

    1. Rounding Down: If the number following the last significant figure (or digit) is less than 5, round down.

    2. Rounding Up: If the number is 5 or greater, round up.

    3. Even/Odd Rule: Round to the nearest even number if followed by 5.

Conversions

  • Equation for Conversion: unit2=unit1imes(conversionextfactor)unit2 = unit1 imes (conversion ext{ factor})

  • Common Conversion Factors:

    • Length: 1 km = 1000 m = 0.6214 mi

    • Mass: 1 kg = 2.205 lb = 1000 g

    • Volume: 1 L = 1000 mL = 10^{-3} m^3

Let’s Check and Analyze:

  • Exercises and Review Questions to reinforce unit conversions and understanding of chemical measurements.

Big Picture in Focus: ULO1b: Understanding Concepts of Chemical Safety
Metalanguage

  • Chemical Laboratory Safety: Control of exposure to hazardous substances to minimize risks.

Ethical Considerations and Safety Protocols

  • Chemical Hazards: Risks related to handling, exposure standards, and emergency protocols, including understanding significant figures and conversions.

Essential Knowledge: Introduction to Chemical Safety

  • Principles of Chemical Safety: Best practices for handling hazardous materials to ensure health and safety.

  • Types of Chemical Hazards: Flammable, corrosive, toxic materials, etc., and their implications in real-world scenarios.

Courses and Schedules

  • Detailed outline of timelines and expectations for learning units across the semester including laboratory sessions and assessments.

BIG PICTURE 2: ULO 2

  • (Subsequent units covering similarly detailed content areas including chemical properties, reactions, thermodynamics, polymers, and sustainable practices)

Assessment, Grading and Communication Structure:

  • Clear expectations for assessments including timelines for submission, penalty policies, grading weightings for various components of the course, communication protocols, and contact information for course coordinators and deans.

(Additional sections covering conceptual frameworks, case studies, practical applications of chemistry in engineering, and more)

CONCLUSION

  • The SIM serves as a comprehensive guide to succeed in BCHE 111/L as students explore the intersection of chemistry and engineering.

  • Continuous updates will reflect the evolving nature of course content and policies.
