My Tree in Autumn


Autumn trees are miraculous. They shine with fireworks of colors.

Let´s find out when, how and why the tree prepares for winter sleep.

Upload your measurements into the GLOBE database and compare your data with schools across Europe.


Select one of the 7 species (Hazel, Fig, Lime, Oak, Cherry, Birch, Beech) that GLOBE students around Europe follow in autumn.


Register for the campaign to obtain 3 activities for students and earn GLOBE certificate for your school! The deadline was extended to September 30th.


What else can you do?

  • Research how the autumn change of trees relates to weather.
  • Take pictures with GrowApp and make a time-lapse video.
  • Share your results and pictures with other schools at the discussion forum.
  • Get inspired by research and activities of other students.
  • Connect to teachers and students from other countries within the School Collaboration group.


The benefits are multiple for the students such as observing the nature and learning to be patient. They analyse the results, make hypothesis and give the conclusion in the end which is the basis for scientific way of thinking.
