Introductory Paper
Project
Description In this project students will choose three different animals for which they will design a zoo habitat. The project will begin with a guest speaker from a local zoo discussing the purpose of zoos. Students will then be taken through a series of lessons in which they explore all the components of a habitat. A lesson on the importance of biodiversity, about the different environments animals live in, the structure of food webs and pyramids, the relationships and behaviors of all kinds of creatures and disease awareness and prevention. The students will have the opportunity to visit the local zoo to observe habitats and see the details of how an actual zoo is designed. This will give the students firsthand knowledge of the real world application of their project. At the end of the six weeks students will complete posters depicting the details of their designs of the different habitats. They will also give an oral presentation to the class.
Driving
Question The local zoo has asked you to design three habitats for three new incoming animals. Identify and incorporate the factors that make a zoo habitat a comfortable place for an animal.
Overall
Goals of the Project This project begins with several goals: to teach students the importance of conservation of habitats and species, enrich studentsÕ problem solving skills through project-based instruction, and alert youth to the value of imaginative thinking in the scientific community. Students will become aware of the changing world around them and the impact of those changes. They will learn how all components of an ecosystem come together to determine the survival of a species. Students will also learn about measures being taken by zoos and conservation societies alike to save endangered species. At the least, this project brings awareness of the importance of biodiversity, but can also inspire students to want to do something about the destruction of habitats and species. The project based instruction classroom provides many opportunities for students to hone their creative thinking skills, and help them to understand the importance of approaching a problem from several different angles. Students will have given an overview of the information they need to design their habitats, and then be given enormous independence with their projects. They will be responsible for researching their individual animals, and they must face and resolve real issues that zoos deal with such as space, cost, and feasibility, thus applying their knowledge to new (but real) situations. Students will also be exposed to several different careers that are available in the science field. Many careers in science are truly interdisciplinary, as they bring together many aspects of history, English, math, art, geography in a single effort of scientific achievement. The design of their habitats is one such achievement. This will broaden studentsÕ perceptions of their career options in science.
Project
Objectives By the end of this unit, we expect students to be able to:
Rationale In a position statement adopted by the National Science Teachers
Association in 2003, the board of directors agree that Òteachers of science must provide their students with inquiries
that mentally and physically engage their studentsÉin ways that facilitate
students' understanding as well as provide opportunities for students
to apply and transfer their knowledge to new situations.Ó The project based learning environment
is an ideal place for students to be engaged, challenged, and exposed
to new circumstances. Such
a classroom provides a jumping off point for students to apply skills
for thinking on their feet in other subjects, and even in their future
careers. Our project, which is part of a project based instruction classroom, focuses on natural habitats. Current statistics show that every twenty minutes the world loses one or more entire species of animal or plant life. Eighty percent of this decline in biodiversity is caused by habitat destruction. Preserving natural habitats and species is becoming a matter of great importance. On the forefront of these conservation efforts are the worldÕs zoos. Our goal is to put our students in the midst of their very own zoo to experience the intricacies of habitat and species conservation. The project utilizes skills from several different areas of
study. The main focus
of the activity is biology, but students must also incorporate math
(writing a budget and calculating costs), English (writing proposals
to the zoo donors and supporters, as well as compiling a final report),
and even art (the habitats should be aesthetically pleasing as well
as functional). This project will allow students
to be exposed to the reality of a need for serious conservation efforts,
given the opportunity to explore new ways of learning, and prepared
for a successful future in science.
Background
The biodiversity of our world is amazing. There are over fourteen
million species on our planet.
Students will consider biodiversity on a large scale, taking
into account the roles that each individual species play in its environment. In studying the importance of biodiversity, students will be
able to deduce the impact of disappearing species in an ecosystem. Natural habitats are carefully kept in
balance partly because of the contributions of the residents. Food webs keep ecological systems balanced
by distributing energy and matter throughout the systems.
The careful balance of these systems has slowly been perfected
through evolution. Organisms
change over time to adapt to their environments, making them a vital
part of the habitat. As genes change by fortunate mutation
(or simply a complete elimination from the gene pool of a species),
new phenotypes become apparent through many generations, and the strongest
and best suited organisms manage to survive in all kinds of habitats. Darwin proposed his theory of evolution
as a principle of Òsurvival of the fittest.Ó Students will explore what this phrase actually means and how
it lends itself to the study of evolution.
These habitats that are able to support so many kinds of creatures
vary from the warmest and wettest tropical forests to the coldest
and driest ice sheets. Evolution has allowed plants and animals
to reach the far corners of the earth, and survive in the most extreme
conditions. Animals are
specially suited for certain kinds of diets and hunting methods, and
their reproduction strategies optimize the survival of young animals. Students will consider why an animal is suited to a particular
climate, a particular food, and particular surroundings. As students design their habitats, they
will have to consider what environment their animals are best suited
for, and explain their reasoning.
Finally, as plants and animals have spread all over the globe,
bacteria and viruses have spread with them.
The smallest and most abundant life forms on our planet, bacteria
can be both good and bad for animals.
Students will consider the implications of the immense presence
of bacteria in any environment, and attempt to protect their animals
from disease. Viruses will also be considered, as students will study the
recent Bird Flu epidemic and the dangers of cross-species transmission. This
unit takes students through some of the biology topics mentioned above,
including evolution, biodiversity, biomes, food pyramids, animal behavior,
bacteria, and viruses. All
of these lessons will relate to the project on zoo habitats. The lessons are designed to help the student
in designing a habitat for different animals. This will help the students see how unique different animals
are and how they adapt to the living conditions of their natural habitat. They will also help the students see all
that must be considered when designing a habitat outside of an animalÕs
natural habitat. Milestones
accompany the lessons that will keep students on track for progressing
through their projects.

Assessments As the project begins, we will gather prior knowledge from the students using a concept mapping assessment tool. This will serve as a kind of pretest for the students to establish what knowledge they are entering the project with. Throughout the project, we will monitor the studentsÕ progress with a series of minor assessments. Also, the students will be required to turn in fact sheets containing the data they have gathered during their research. In this way, we will be able to ensure that all students are moving at a similar pace. At the end of the project, we will assess the studentsÕ overall improvement by allowing them a brief presentation (both verbal and visual) in which they describe one of their habitats in depth. These presentations will be followed by question and answer sessions in which the students will have to defend their choices and explain their reasoning.
