This activity is intended to capture the dynamic nature of the development of diseases in plants. The background image is a diagram showing the disease cycle of target spot of tobacco. The hotspots indicate key stages in the disease development cycle, and are augmented by photos and videos which help to tell the full story of the development of this plant disease. The multilayered format of the Image Hotspots content type make it ideal for explaining dynamic processes such as disease development. I have attached some screenshots and the H5P file to this post.
