How fast does it grow, what is it made of?
An exercise for primary, secondary and university classes.
Learning objective:
Students learn about the species of trees that are found on the site. Each different species has different characteristics and students can determine the age and height of a particular tree on the plot with simple activities using a pencil, measuring tape and mathematical equations. Students are grouped into pairs and take turns measuring the height of a tree using a pencil and their partners distance from the tree. The age of the tree can also be determined by measuring the diameter of a tree and applying a mathematical equation based on the current year and the species of a tree. Measurements can be repeated year by year to show growth process. For a more elaborate approach, students can try to use the allometric equation to estimate the stored CO2.
