Entry Events
Events that will be used to introduce the project to studentsInvasive Species News Report
Students encounter a news report about an invasive species devastating a local ecosystem. They discuss the factors contributing to the uncontrolled growth and the potential consequences.Portfolio Activities
Portfolio Activities
These activities progressively build towards your learning goals, with each submission contributing to the student's final portfolio.Natural Habitat Observation Setup
Students will create a natural outdoor habitat, such as a marked-off area in a field, a section of a school garden, or an area near a tree, to observe a chosen organism and its interactions with the environment. They will select easily observable organisms like ants, pill bugs, or dandelions. They will also establish a system for monitoring and recording environmental factors like temperature, sunlight, and available space using readily available materials like sticks, rocks, and string.Steps
