Changes of the light condition in a forest with Cobra SMARTsense

Article no: P1520769
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> Unknown

Principle

Why are there so few different plants in a deciduous forest? In a deciduous forest, apart from trees of approximately the same height, hardly any other plants grow, except for young plants of the same tree species. This experiment shows how the light intensity in an oak-beech mixed forest changes during the foliage in spring and what consequences this has for the vegetation.

Benefits

  • experiment is part of a complete solution with numerous experiments in the field of ecology
  • Measurements possible indoors and outdoors, for mobile use
  • Especially understandable and didactically prepared description of the experiment (relevance to everyday life, etc.) including protocol questions.
  • Future-oriented teaching: Integration into digital science lessons with tablets or smartphones.
  • Increased motivation of students by using the intuitive measureAPP.
  • Increased media competence.

Tasks

  1. measuring the light intensity in a forest at weekly intervals during bud burst
  2. comparison of the measured values

Learning Objectives

  • Vegetation
  • Sun Plants
  • shadow plants
  • photosynthesis factor Light intensity
