Beach Erosion and Lesson Activities

The video tutorial for second graders covers the topic of changing landforms, focusing on how small changes can accumulate over time to create significant transformations. The lesson reviews a previous activity involving a model of erosion using cotton balls and introduces a new activity using reference books to gather evidence of change. The case study of beaches illustrates how erosion and deposition alter landforms gradually. Students are guided on completing a worksheet to document their findings and are encouraged to explore further through a related YouTube video.
