My Tree in Spring


Trees are beautiful. They wake up again each spring.

Observe your tree from buds to leaves and upload your measurements into the GLOBE database.


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


What else can you do?

  • 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.
  • Post a video story of your tree. 
  • Connect to teachers and students from other countries within the School Collaboration group.


„During observations, the students tend to be more perceptive as they were interested in how the weather temperature affected the budburst. They’ve found out which tree burst earliest and which latest, which tree’s leaves grew fastest during the same weather conditions.“
