Case Study in Brief

We ask participants to collect or use a selection of leaves with different shapes. They release the leaves one at a time from a height that allows them to observe how each leaf falls. 

Participants draw the falling pattern of the leaf they observe. Afterward, they exchange their drawing with another group. Each group then studies the drawing they receive and tries to guess which type of leaf it represents. 

The goal of this activity is to sharpen observation skills and show how drawing, as an artistic tool, can support the understanding of a scientific concept. It links visual expression to the study of motion in physics.

Practical Details – Facilitator’s Notes

We design this activity as a taxonomy task because it focuses on making informed distinctions between different types of leaves through hands-on observation. 

The session runs for 1.5 hours. This gives enough time for all participants to present their findings. In this workshop, we divide participants into seven groups, which also allows us to introduce a wider variety of leaves. Each group works with a different type, which adds complexity to the drawing exchange and guessing. Still, the activity also works with a smaller number of groups, with a minimum of two. 

We set up the room with enough chairs and desks for all 25 participants. For the leaf activity, we place participants in groups of about three. Each group chooses a desk and selects one leaf from a shared collection. They also decide how high to release the leaf, for example, by standing on a chair. 

The participants are newly graduated trainees, employed in various companies and public institutions across Western Norway. They all take part in the TraineeVest programme coordinated by the Bergen Chamber of Commerce. Their backgrounds vary, with education and work roles in fields such as IT, administration, economy and marketing. 

To run the activity, each group uses a blank sheet of paper, a pen or pencil and a set of leaves to choose from. We prepare all materials in advance, including the leaves, which are collected and provided by HVL staff. 

This activity shows how art-based and science-based inquiry can work together to deepen understanding. The more learners focus on the artistic details in what they observe, the stronger their scientific reasoning becomes. We see this clearly when groups compare drawings and begin to discuss how leaf shape affects falling patterns. These conversations help develop both observational skills and scientific argumentation.
