The Chesapeake Bay Ecosystem

The students will answer the questions given in the “The Chesapeake Bay Ecosystem Publication” they read. (see on page 1 of the Chesapeake Bay Ecosystem Publication). Each question is worth 5 points, and total is 20 points). Individual students written answers will be incorporated in their Chesapeake Bay Ecosystem model collage grade.

Objectives
1. Students will be able to show how much they understand and retained from the activity they have completed.
2. Students should be able to give accurate answers to concept questions posed.
Materials
1. Their Textbook
2. The Chesapeake Bay ecosystem publication
3. Chesapeake Bay ecosystem "Grade Feedback form"
Procedure

Students will answer the questions given in the “The Chesapeake Bay Ecosystem Publication” they read. (on page 1 of the Chesapeake Bay Ecosystem Publication). Each question is worth 5 points, and total is 20 points). Individual students written answers will be incorporated in their Chesapeake Bay Ecosystem model collage grade.

 

Let them write their answer on the Grade Feedback Form for the Chesapeake Bay Ecosystem (See below)

 

Lab grade will be based on their ecosystem model collage:

 

Accuracy – 40%

How well the group work together – 10% (This grade is given while students are working together in the exploration part of the lesson)

Overall quality (neatness, order) – 10%

Presentation – 20%

Individual written answer – 20% (percent contribution as follows:   [(score/total) X 100 X 0.20)

 

Class Help: 

 
Keeping a picture of each group’s work will give you better perspective of each group’s work and allow you to better evaluate each work and grade it objectively. While students are working together teacher should be going around and giving group performance rating based on how well their group worked together. This will also give them an immediate feedback.
