B1 Water cycle (teacher instructions)

Experimentation instructions for Experimento - 10+:
Background information on the content and practical information on conducting the experiment "Water cycle - Evaporation from plant leaves".


This very simple experiment is ideally suited as an introduction to various topics. For example, it can be used in geography class to study the water cycle and the climate, and in biology class, to study water as the basis of life and its importance in plant metabolism. This experiment can even be used in physics and chemistry to present the states of matter using a real-world example. The materials and apparatus supplied allow eight groups of students to conduct the experiments simultaneously.

Notes:
· Observe the safety information in the instructions as well as the applicable safety guidelines for your school.
· All materials mentioned in the instructions will have to be purchased directly from commercial sources.
