Set-up Directions:
Before beginning this lesson make sure that all web sites are working and that the content is appropriate for the class. It is also helpful to bookmark web sites before beginning the activity to avoid spending time typing in web addresses during the lesson. Also, print enough copies of Handout #1: Chesapeake Bay Problems and Handout #2: Saving the Bay for each student.
Teacher Presentation & Motivation:
Facilitate a brief discussion. Ask students, “How many of you have ever been to the Chesapeake Bay? Do any of you know what some of the problems facing the bay today are? Why do you think it's important that everyone does their share to help keep the Bay clean and safe?
Say to students, “Over the next few days we are going to learn about some of the problems facing the bay and your task is going to be to create a book for younger students (a book for second grade is recommended) to teach them about ways that they can help preserve the Chesapeake Bay. (5 minutes)
Activity 1 - About the Bay (10 minutes)
Project the About the Bay page from the Chesapeake Bay Program’s web site for the entire class to see http://www.chesapeakebay.net/about.htm.
Have a student volunteer read the introduction part: “The Chesapeake Bay -- the largest estuary in the U.S. -- is an incredibly complex ecosystem that includes important habitats and food webs. The Bay itself, its rivers, wetlands, trees and land all provide homes, protection or food for complex groups of species. Fish of all types and sizes either live in the Bay and its tributaries or they use the waters as they migrate along the East Coast. Young crabs hide from predators in underwater grasses, while oysters filter water as they feed on plankton. The intertwined combinations of relationships are countless.”
Explain to students that tomorrow they are going to have a chance to explore this web site in greater detail.
Activity 2 - Problems and the Bay (15 minutes)
Distribute Handout #1: Major Problems Facing the Chesapeake Bay
Read through the document aloud with the class. Have a different student volunteer to read the information about each problem. Answer any questions students have about the problems addressed.
Activity 3 - Saving the Bay (15 minutes)
Using an LCD Projector or SmartBoard where everyone in the class can see, project Thinkport’s Bay Trippers: An Online Field Trip to the Chesapeake Bay interactive http://baytrippers.thinkport.org/learn/what.htm
Explain that now that students have seen what some of the problems are, they are going to take a look at possible solutions. Ask for student volunteers to read through the different suggestions for saving the Bay. Distribute Handout #2: Saving the Bay so students can read along and take notes.
Be prepared to get into a discussion about the solutions offered. Find out from students how many of them think they help conserve water and save energy. Engage the students in a conversation about the problems and the solutions.
The solutions identified in the interactive are as follows:
Conserve Water
Save Energy
Plant native trees, shrubs and other vegetation
Reduce solid waste
Compost
Reduce your use of toxic household products
Keep your lawn “green”
Drive less
Inform others
Get out into the natural world
Wrap Up:
Tell students that tomorrow they are going to do more extensive research into one of the issues above. Have students write on a piece of paper their first and second choice for conducting more in-depth research on a potential solution. Based on their interests, they will be placed in groups of 2-3.
If there's time, form the groups at the end of the class, so students will know what they are going to research the next day. Tell students that they will be drawing pictures that go along with potential solutions, so for homework, they can begin to think about what they would draw.
