Entry Events
Events that will be used to introduce the project to studentsThe Great Seed Disaster
Students receive a package of mixed seeds (some real, some not) and are tasked with planting them in a small container. The catch? The seeds are nearly impossible to handle individually, leading to overcrowding. This sparks a discussion about the challenges of planting small seeds and the need for innovative solutions.Portfolio Activities
