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.


Registration will start in Mid-August so please come back to check this page by that time. Teacher who registers for the campaign will obtain 3 learning activities for students and will have the opportunity to earn GLOBE certificate for  the school!


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.
  • Read the article "Why do the leaves change color?" and learn why and how the autumn change of trees happen.


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

Activities for students:


To observe and record your tree color change (activities 2 and 3) you will need the GLOBE Plant Color Guide. If you don’t have the Guide, please contact your GLOBE country coordinator.

To learn, how to enter the data and how to create a graph of leaf color change using GLOBE Visualisation tool watch a recording of the webinar "How to Upload Data to the GLOBE Database".
