Target group: students in grades 7–9
The aim of this activity is to learn a method for determining tree height by combining natural science and mathematics skills. The use of research elements encourages students to engage deeply in the tasks and develop a stronger, experience-based understanding.
Students also gain an understanding of the concept of a “biologically valuable tree.” Working in groups, they learn how to measure tree height using a Bormann measuring stick, identify variables, and formulate a hypothesis. The research question explored is: Do trees of similar height have the same or similar timber volume?
Linked to the Grade 9 Biology topic: “How are organisms connected to the environment in which they live?”
During the activity, students:
- learn how to conduct field research in a forest environment,
- measure tree height using a Bormann stick and a tree-height measuring device,
- develop an understanding of timber volume,
- identify organisms using classification guides and observation,
- understand the ecological importance of biologically valuable trees (for example, as habitats for insects).
Participants also practise teamwork while solving simple scientific problems, sharing responsibility for results, and recognising the benefits of cooperation. The activity promotes sustainable and environmentally responsible behaviour and encourages students to evaluate their research process and suggest improvements for greater accuracy.
