Before Reading

After Reading

_____ Vernal pools are shallow, seasonal ponds that are linked to permanent streams and disappear for a while during most years

__

_____ Vernal pools contain numerous types of fish through out the year. __

_____ Vernal Pools dry up at the end of each summer and gradually fill with water again during the fall, winter, and spring.

__

_____ Vernal Pools are an ideal habitat for frogs, salamanders, and insect larvae. __

_____ Vernal pools occur naturally or in human-made ponds, roadside ditches, canals, abandoned quarries, or foundations of abandoned buildings.

__

_____ Off-road vehicles driven through vernal pools, even when they are dry in summer, can damage these fragile ecosystems.

__

_____ Vernal Pools are a habitat (particularly for breeding purposes) for amphibians (such as a frog or salamander) and invertebrates (lacking a backbone) whose numbers otherwise might be less if fish were present.

Anticipation Guide

Setting Our Purposes For Setting Our Purposes For ReadingReading

During Reading Strategies:

Research Procedure:Student pairs will be rotating to 5 areas in the room to learn information about Vernal pools. The teacher will go to each station and display the book or article and read the title with the students. A small exert from each selection will be shared aloud with the students . Students will be told that they will find the answers to their prereading questions and the anticipation guide statements by spending time at each station to read about vernal pools. Explain that there will be a scavenger hunt card at each station that the students will be required to complete together. All information collected at each area will be recorded in their Vernal Pool Learning Logs.

Explain to the class that our goal is to learn as much as possible about Vernal

Pools from our research station rotations and that when we come back together as

a class at the end of the lesson, we should all be experts on vernal pools and will

look back at the statements on the anticipation guide and our prereading

questions to evaluate our learning from the research investigation.

Meet back together as a group. Review prereading questions posted on our chart

to see how many of the them we can answer from

our investigation. Students will be asked to share some of the information they learned that surprised them

about Vernal pools?

Look back at some of the questions from the scavenger hunt cards and discuss their answers. Ask volunteers to summarize the main ideas of

each of the texts from the investigations at each station.

What distinctions can be made about vernal pools or wetlands in our community? How are Vernal Pools different from other wetland environments? Describe some of the special features of a Vernal Pool ? Why are some Vernal Pools and wetlands in danger? Describe the effects the destruction of vernal pools have on the larger ecosystem? Explain the value of Vernal Pools to our environment and cycle of life.

Each student will choose one of the key vocabulary words from our investigation to work through the Frayer model to share for our next class.

Real World Application Lesson: Since Maryland doesn’t have any laws for protecting Vernal pools students will be asked to write an action plan, in their learning log, for preserving Vernal Pools in Maryland. They will be informed that in order for our action plans to make a difference they need to be shared with public officials so we will be sending our plans to our local newspaper and government officials to publicize this ecological need.

http://www.bayjournal.com/article.cfm?article=3867

A discussion about the factual information that they would want to include in their plan will follow. Students will be allowed to return to the reference stations to collect additional data in a graphic organizer to include in their action plans. Rough drafts of the plan will be written in their learning logs. Final copies of the action plans will be typed on the computer and posted on our Vernal Pool Wiki.

Vernal Pool Maryland Brochure

How can Maryland Protect It’s Vernal Pools?

Two follow-up lessons will be conducted where students will create brochures using Microsoft Publisher. The objective for the brochure will be for students to explain the value of Vernal Pools to Maryland’s ecosystem. I will explain that the brochures could be distributed to the community to make them aware of the need for Vernal Pools to our community.

DifferentiationDifferentiationVERNAL POOL MODELS

Those that finish early or who can not work at one of the research stations will build models to show the changes that occur in vernal pools throughout the year as the seasons change. They will include written captions to explain the shape and geologic composition of the earth and the effects weather, rain and sun have on the pools, and the resulting changes in flora and fauna of the vernal pool ecosystems.

VISIT A VERNAL POOL – Use links from Wiki

I will plan a walking trip to explore a vernal pool in our community.

Students would be asked to carefully observe and record the types and numbers of different plants and animals that they observe in the vernal pool. When we return to

school, we would create a mural to display in the hall of what we saw and

learned about in the vernal pool creatures.
