Assignment 1 Questions (Total: 5 points) Instructions: Answer the following questions below. Show your work and submit individually on UB Learns. Name: _______________________________ Carbon Footprinting: Australian Bauxite is shipped 3,000 kilometers to New Zealand in a bulk cargo ship. The ship carries 300,000 metric tons of ore and consumes 1,400,000 liters of fuel oil on the journey. Fuel oil emits 38.2 kilograms CO2 per liter. For bauxite ore shipped from Australia to New Zealand, what is the emission of CO2 in kilograms per ton kilometer travelled? (1 point) A consumer who lives in New York switches from a 60-watt incandescent bulb to an 8-watt LED. Assume usage remains the same, which 4 hours per day on average. Electricity costs the consumer $0.12 per kWh. (A kWh is the amount of energy needed to produce 1000 watts of energy for 1 hour.) The incandescent light bulb costs $0.40. The LED costs $12.00. The LED lasts 27,000 hours whereas the incandescent light bulb lasts 1000 hours. Including the cost of replacement bulbs and the cost of electricity, how long does it take for the LED to breakeven? (That is, after how much time will the consumer have spent as much with the LED as with the incandescent light bulb.) (2 points) The consumer’s electricity emits 450 kilograms CO2/MWh (1 MWh = 1000 kWh.) How many kilograms of CO2 would the consumer emit to operate the 60-watt light bulb for one year? (1 point) Calculate your individual carbon footprint using TerraPass’s carbon footprint tool (https://terrapass.com/carbon-footprint-calculator/) and report the major category of emissions. What are the major emission causing activities. Where do you see a possibility of reducing your daily carbon emissions and what steps can you take? (1 point)

AI Reasoning:

Alignment with Outcomes:

  • The assignment aligns with learning outcomes by assessing students' understanding of carbon footprint calculations and environmental impact. However, it could be improved by explicitly linking these calculations to broader sustainability concepts and implications.

Cognitive Demand:

  • The assignment requires students to apply mathematical calculations and consider environmental consequences, which involves some higher-order thinking. To enhance cognitive demand, adding a reflective component on the broader implications of carbon footprints could deepen critical thinking.

Authenticity/Context:

  • The assignment provides a real-world context by using examples of carbon emissions from shipping and electricity usage. To enhance authenticity, incorporating more diverse scenarios or industry-specific examples could enrich the context.

Accessibility/Equity:

  • The assignment is accessible as it involves basic calculations and common environmental concepts. To improve equity, offering alternative scenarios or case studies from different regions could enhance inclusivity.

Process Visibility:

  • The assignment lacks explicit requirements for documenting the problem-solving process. Adding a step-by-step breakdown of calculations or reflections on decision-making could enhance process visibility.

AI Transparency & Ethical Literacy:

  • The assignment does not directly address AI use, which is not a requirement for this topic. However, integrating discussions on AI's role in carbon footprint analysis could enhance ethical literacy.

Teaching Methods:

  • The teaching methods engage students in practical calculations and real-world applications. To improve, incorporating group discussions or peer reviews could enhance interactive learning experiences.
