**Topic:** CO2 calculator
Calculating CO2 contamination
**Level: **students of the age 14 – 15
**Topic:** students know the basic causes for CO2 (transportation, home energy consumpiton)
**Required knowledge:** knows how to use a computer (Excel, Internet), knows the effects of CO2 to the enviroment
**Goal: ** The CO2 calculator help students to the amount of CO2 which is produced when using electronies at home, transportation, heating.
**Specific goals: **by the end of the activity students:
- can analyse and save the results in such a way that they can be used again and the amount of CO2 can be resulta
- offer solutions for reducing the CO2 calculator
**Methods:** lecture, discussion, using the CO2 calculator
**Time and managment:**
The topic invoves 2 lessons and preparation
Preparation
Students find out the following:
- how much electricity is use per month per household
- how many km per month are travelled by a means of transportation
- how high is the usage of petrol (l per km)
- what hind of energy is used to heat the household (how much is use in average per month)
** Lesson 1 ** introducing the topic, 15 min lecture, 20 min discussion, the demonstration of the CO2 calculator
**Lesson 2 ** activities in the computer lab – using the CO2 calculator, analysing the results, discussion, mahing charts, finding solutions
**Necessary means:** computers with the access to Internet, handouts, electricity bills |
