In Lesson 4: Carbon Cycle, students explored the ways that carbon is both produced and sequestered, and described how they would reduce carbon in the atmosphere (using text and visuals). As a follow up to calculating their personal carbon footprint in Lesson 3, students will calculate the carbon footprint of their zip code. Next, they will use the iTree Canopy online application to assess the area of tree canopy in their defined area and how much carbon is already being captured by the existing trees.
Students walk around their schoolyard to conduct a Tree Inventory that assesses land usage and the existing trees. They note the different ways that the land is being used (i.e, residential, commercial, parks) and draw these on the map in their Lab Journal. They also draw all of the existing trees on their school’s block. In addition, students collect data about each tree (i.e., evergreen or deciduous, condition of tree and the impact on the area it is growing).
This activity worksheet guides students on how to practice "catch and release" insect collecting, where to look for insects, and how to observe them after they are caught.
The presentation focuses on biodiversity, how invasive species affect biodiversity, who is involved in detecting invasive species, and plant biosecurity. It also features other plant biosecurity issues such as those that affect our food supply, the USDA Select Agents and Toxins list, and agroterrorism events of the last century.
Students search a curated list of websites to gather known information about SOD. They then formulate lists of questions to ask an "SOD expert" and discuss as a class.
