Why are there so means leaves on the floor in autumn? - Teacher's Notes

In an educational unit exploring the seasonal changes of trees, a key objective is to understand why trees shed their leaves in autumn. The lesson introduces students to the concept of deciduous trees, which lose their leaves annually, and contrasts them with coniferous or evergreen trees that retain their foliage year-round. The new vocabulary is supported by a video resource that visually explains the process and changes that occur in trees throughout the seasons.

The lesson then shifts focus to the transformation in leaf pigmentation, observing how leaves change colour before they fall. Additionally, the terms 'migrate' and 'hibernate' are presented to the children, broadening their understanding of seasonal adaptations in nature. Students are encouraged to research and learn about various birds that migrate to warmer climates during the colder months and animals that enter hibernation to conserve energy. This comprehensive approach helps students grasp the interconnectedness of seasonal changes and behavioural patterns in the natural world.
