Why are there so means leaves on the floor in autumn? - Presentation

An educational presentation explores the seasonal changes that lead to the abundance of fallen leaves during autumn. It delves into the transformative journey trees undergo throughout the year, with a particular focus on deciduous trees that shed their foliage in this season. The presentation introduces the terms 'deciduous' and 'coniferous' (evergreen), providing a contrast between trees that lose their leaves annually and those that retain them. The changing leaf colour is highlighted as a significant autumnal feature, where the green pigment fades due to reduced sunlight and lower temperatures, allowing the natural reds, browns, and oranges to dominate the landscape.

The presentation also touches upon the behavioural patterns of wildlife during autumn, such as the migration of birds and the hibernation of certain animals. It encourages students to observe and understand the reasons behind these changes, including the decrease in food production within trees and the preparation of animals for the colder months ahead. To deepen their understanding, students are tasked with researching and writing about the characteristics of autumn, including the changes in weather, animal behaviour, and the environment's overall transformation during this picturesque season.
