Day Length - Presentation

The educational presentation on 'Day Length' delves into the fascinating Earth Science topic of seasonal changes. Students are invited to explore the concept of day length, with a particular focus on the differences between summer and winter. The presentation poses key questions, such as whether day length in summer is longer than in winter, if different parts of the world experience varying daylight hours, and if seasons are opposite in the different hemispheres. Additionally, students are encouraged to identify countries located in the northern or southern hemispheres. The learning journey includes watching an educational video to answer questions about the Earth's axis, the reason for night and day, and the duration of Earth's rotation.

Further investigation in the presentation includes examining an 'Orange Planet' diagram to understand global day and night patterns, and researching day length during the Summer and Winter Solstices in various cities around the world. The presentation also highlights the fact that at the equator, day and night lengths are constant throughout the year, while at the poles, there can be continuous daylight or darkness for months, depending on the season. An interactive investigation prompts students to consider why it is warmer during the daytime and in places with longer daylight hours, particularly in summer. The presentation concludes with a review of what has been learned, reiterating the understanding of day length variability, the opposing seasons in different hemispheres, and recognition of hemispheric locations.
