Secrets of the Pond
The primary objective of any unit on pond habitat is for students to develop an understanding and awareness of the delicate ecosystem of the pond. By the end of the unit, all students should be able to identify plant and animal life, discuss life cycles and understand environmental concerns connected to ponds.
Introduction to Pond Habitat:
When teaching a unit on pond habitat, a good educational movie on the subject is a highly effective means of introducing this unique habitat to students. If there are no local ponds to visit, this also gives students a visual perspective and understanding of ponds.
Movies can be obtained through the school or town library, or, if this is something the teacher wishes to have as a long-term resource, there are various places to purchase an educational film on pond habitats. For instance, the Missouri Botanical Gardens (MBG) has the film, The Secret of the Pond available to teachers at a discounted price. The film is created for PreK-3rd grade students. For grades 4-8, the MBG has a film, Exploring Ponds and Lakes. For high school students, the videos, Fresh Water Ponds is available through the National Parks Service.
All of the videos mentioned above are short introductions.
Prior to viewing the movie, introduce vocabulary to the students. For the younger students, this can be done with an interactive teaching wall on Pond Habitats. Words such as pond, grass, frog, and lily pad can be written on cardboard, which the students then match with pictures on the teaching wall.
Older students can begin by brainstorming words they already know. After they have brainstormed, a handout with vocabulary words can be given out and reviewed.

Objective of Field Trip: To acquire hands-on knowledge and understanding of pond habitats - to examine critically the habitat - observe the life cycles of plants and creatures in the pond
- students will be given a science journal in which to note their observations of plant and animal life at the pond
- students through observations will produce a food chain
- students, after a discussion in the classroom on environmentalism, can pick up trash around the pond - Note: it will be necessary to supply students with heavy duty trash bags and non-latex gloves
- students can take pictures of plants and creatures at the pond for a PowerPoint presentation to be given at the end of the unit
Students will create a PowerPoint presentation to demonstrate what they have learned about pond habitats. Students can be assigned a specific element of pond habitats to report on or can give an overview of what they have learned.

Objective: Students will describe the plants and/or creatures of the pond through creative writing, which allows them to recall and express their experience either from the field trip or from the video.
Task: Students will create a short essay or a poem (haiku is an excellent choice for any form of science) about an element of the pond habitat. Young students can do name (acrostic) poems with vocabulary words such as, dragonfly or lily pad.
Final Project: At the end of the unit, the students' work can be made into a publication on pond habitat that is kept in the classroom library.

Assessing students on any part of this unit will include:
- participation in discussions and activities
- ability to contribute to questions and answers
- completion of their science journal - neatness, observations, conclusions
- completion of their presentation - relevance, ability to answer questions
- completion of their creative writing piece - creativity, ability to describe and express their observations

World Wide Web Resources
There are several excellent online resources, especially for elementary/middle school students, that can be accessed which give students various opportunities to learn about pond habitats.
For example, Young People's Trust for the Environment has graphics, downloadable worksheets, projects and lots more, or, go to 42 Explore.com for a host of resources for teachers to use in teaching a pond habitat unit.
