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:

1. how much electricity is use per month per household
