This activity consists of two parts. In the first part the Carbon tree simulation (hiilipuu.fi) is used

to study how pine binds carbon dioxide from air at different times of year and time and in different weather conditions. Schools can also borrow a “carbon suitcase” from the science center; the suitcase includes carbon dioxide, temperature and light sensors. The sensors can be manipulated (by spraying, heating, and illuminating), whereby the suitcase reacts to changes. In the second part of the activity pupils calculate the energy required to charge q cell phone battery and the carbon dioxide emissions it causes, the carbon footprint, and the time needed to re-carbonize the carbon from the single pine.

All ages
