Changes of the light conditions in a deciduous forest

Продукт No: P1520762

Principle

Why are there only a few different kinds of plants in a deciduous forest? Except for having trees that are all approximately of the same height, hardly any other plants grow in a deciduous forest, except for young plants of the same type of trees. This experiment shows how the light intensity in a mixed forest of oaks and beeches changes in the spring during the foliation of the trees. It also demonstrates the effects on the vegetation.

Benefits

  • Experiment is part of an experiment set with numerous experiments in ecology
  • Universal handheld measurement device can also be used for other measurement parameters relevant in ecology, biology and chemistry
  • Outdoors measurement possible, for mobile use
  • Graphical display of measurement data
  • Data can be saved on SD memory card
  • All data can be transferred onto a computer for data analysis
  • Data analysis software can be freely distributed

Tasks

  1. Measurement of light intensity in a forests week by week during bud burst
  2. Comparison of measurement values

What you can learn about

  • Vegetation
  • Shade plant
  • Heliophyte
  • Photosynthesis factor light intensity
