CSI Clamshell Investigation Lesson

Students will learn about the predator/prey relationship that exists between moon snails and clams. Following completion of this lesson, the students will be able to: 1) Explain how moon snails eat and where the holes in clamshells come from 2) Draw conclusions from data collected 3)Use math and graphing to determine if there is a relationship to a clam's size and its likelihood tobe eaten by a moon snail.

Green Eggs and Sand

Green Eggs and Sand is a Tri-State Horseshoe Crab/Shorebird Education Program. The curriculum, designed for middle and high schools students, was developed by coastal managers and teachers from Maryland, New Jersey, and Delaware. Teacher workshops are held on the spawning of the horseshoe crab, the interrelationships with other species and how management decisions are made. The first three curricular modules were designed so you can introduce your students to the lives of horseshoe crabs, their extraordinary history, ecological niche, and interrelationships with other species. The fourth and culminating module integrates all this information to prepare students to confront the multi-faceted challenge of managing horseshoe crabs, a natural resource. Parts of this curriculum may be used independently. Optional extension activities are included to increase your flexibility. The curriculum interdisciplinary with lessons that integrate one or more of the following subjects: history, science, language arts, reading, and math.

Meal Deal Teachers Guide

In this interactive, students play a card game that simulates food chains that exist within the Chesapeake Bay ecosystems. In doing so, they learn about the interconnectedness of the various creatures living in the Bay. Finally, they extrapolate their knowledge to answer the questions: Are all creatures in the Bay equally important? What difference does it make if one organism disappears from the ecosystem? And what difference does it make if an invasive species enters the food chain?

Food Webs in the Bay

The goal of this activity is to acquaint students with a type of ecosystem, the submerged aquatic vegetation (SAV) of a bay, and how different organisms of that ecosystem compete with one another for resources. This lesson makes use of the Chesapeake Bay as an example, but could be adapted as necessary to make use of another bay area of interest. The lesson includes several components (research, oral reports, creation of a food web, and discussion), and will most likely take 3-4 class periods to complete.
