Activity One - Journey 1 Car versus Bus

1. Elizabeth has a small engine car, less than 1.4 litres. Each day she drives 10 kilometres to work and 10 kilometres home from work. For every kilometre she drives 0.17kg of CO₂ is produced. How many kg of CO₂ does Elizabeth produce each day just going to and from work by car?



2. Elizabeth could take the bus. The bus would not go on a direct route to work. One the bus she would travel 15 kilometres to work and 15 kilometres home from work. For each kilometre Elizabeth travels on the bus 0.06kg of CO₂ is produced. How many kg of CO₂ would Elizabeth produce each day travelling to and from work by bus?



3. What is the difference between the level of CO₂ produced by car travel and bus travel?

Activity Two - Journey 2 Family Travel

1. The Jones family are going on holiday to a place called Wick. They live in Aberdeen. Wick is a total of 343km. The Jones family drive a car with a large engine, larger than 2.1litres. For every kilometre they drive 0.27kg of CO₂ is produced. How many kg of CO₂ will be produced by travelling to Wick?


2. There are five members of the Jones family. 0.06kg of CO₂ is produced by travelling 1 kilometre on a bus. If each member of the Jones family were to travel by bus how many kg of CO₂ would be produced? What is the total for the whole family?


3. Which produces more CO₂ , the Jones family travelling by bus or by car to Wick?


4. There is another dimension to the discussion that needs to be considered. The bus would be going anyway so would it be correct to calculate the CO₂ production as 0.06kg per member of the family. Once you have completed the questions debate this with others who have completed the questions.
