SC250: Science for Everyday Life Unit 4 Lab Assignment Data Collection & Unit Conversions

Part 1: To complete this lab, you must collect data by interviewing friends, family, coworkers, neighbors, etc., using any method you prefer. Ask your subjects the following questions: 1. What is your height? 2. Approximately how much do you weigh? If you prefer not to give your weight, how much does your bag (purse, backpack, lunch bag, etc.) weigh? 3. What is the furthest you have ever traveled from your home (in distance)? (This can be approximated using an online mapping service e.g., Google Maps™, MapQuest™). Be sure to ask and record the units of measurement your subject reports for each answer.

Next, you must convert this data into different forms of measurement:

• Height in inches and centimeters
• Weight in kilograms and pounds
• Distance in miles, yards, and meters

Show your work and the equations used in making these conversions. Partial credit will be awarded for answers without formulas and for incorrect answers where the correct formula was applied. Report your collected data and conversions in the table on the following page.

Part 2: Examination Questions

1. Would a change to the Metric system be beneficial to the United States? Why or why not?
2. Explain why you think it would be hard for the United States to switch to the metric system.
3. Identify one specific job that requires frequent measuring, such as a chef, architect, or nurse. Analyze how a change to the metric system would impact their job, including whether they would need to communicate differently, buy new equipment or tools, and how previous work-related materials would be affected.

Introduction

The purpose of this assignment is to collect real-world measurement data by interviewing individuals and converting these measurements into various units. Additionally, the assignment explores the benefits and challenges of transitioning to the metric system in the United States, along with analyzing the impact on specific professions that require frequent measurements.

Data Collection and Conversion Methodology

To gather data, I interviewed four volunteers—two friends and two family members—asking about their height, weight, and the furthest travel distance from their home. I recorded the units of measurement they reported in and then converted these values into the required units using standard formulas.

For height, I used the conversion factor 1 inch = 2.54 centimeters. For weight, I employed 1 kilogram = 2.20462 pounds. For distance, I used 1 mile = 1,760 yards and 1 mile = 1,609.34 meters. These conversions are fundamental in understanding measurement systems and their applicability.

Data Summary and Conversion Work

Analysis of Metric System Benefits and Challenges

Benefits

The metric system simplifies scientific and international communication due to its decimal-based structure, which allows for easier calculations and conversions. It is also more consistent and reduces the errors that often occur with non-standardized units.

Challenges

The transition to the metric system in the United States could face significant logistical and cultural challenges. These include the need to retrain personnel, replace measuring equipment, and update educational materials. Resistance from the public accustomed to customary units may also slow the process.

Impact on a Profession: Nursing

In the nursing profession, accurate measurement of patient vital signs and medication dosages is critical. A shift to the metric system would streamline many processes, especially since medication dosages are often calculated in milligrams and milliliters. Transitioning would involve updating equipment such as syringe sizes, medicine containers, and charts. Existing materials, such as medical records and educational resources, would need revision to standardize units and prevent errors.

Conclusion

Interviews with individuals provided practical data that demonstrated the differences in units of measurement. Converting these to multiple units underscored the importance of understanding different measurement systems. While adopting the metric system offers clear advantages in precision and international standardization, the transition poses logistical and cultural hurdles, especially in the United States where customary units are deeply ingrained. For professions like nursing, the change could improve efficiency and safety by standardizing measurements across different contexts.
