-"As scientists, many of us have had profound experiences of awe and reverence before the universe. We understand that what is regarded as sacred is more likely to be treated with care and respect. Our planetary home should be so regarded. Efforts to safeguard and cherish the environment need to be infused with a vision of the sacred. At the same time, a much wider and deeper understanding of science and technology is needed. If we do not understand the problem, it is unlikely we will be able to fix it."- Carl Sagan.
Introducción
- "Como científicos, muchos de nosotros hemos tenido experiencias profundas de respeto y reverencia ante el universo. Entendemos que lo que se considera sagrado es más probable que sean tratados con cuidado y respeto. Nuestro hogar planetario debe ser considerado como tal. Salvaguardar y cuidar el medio ambiente deben ser infundido con una visión de lo sagrado. Al mismo tiempo, se necesita una comprensión mucho más amplia y profunda de la ciencia y la tecnología. Si no entendemos el problema, es poco probable que se podamos arreglarlo. "- Carl Sagan.

Our world is in danger- not from invading aliens or colliding comets, but from the consequences of our own irresponsible actions. It has been widely documented that our environment is warming, we are destroying the ecosystems around us and dirtying our water systems on which we depend. Obviously, there is a problem- but do we understand the delicate systems in which we live and how the destruction of even one of these can have irreversible effects.
Nuestro mundo está en peligro, no de extranjeros invasores o de los cometas que chocan, sino de las consecuencias de nuestras acciones irresponsables. Se ha documentado ampliamente que nuestro medio ambiente se está calentando, estamos destruyendo los ecosistemas que nos rodean y estamos ensuciando nuestros sistemas de agua de la que dependemos. Obviamente, hay un problema, pero de veras entendemos lo delicada que son los sistemas en la que vivimos y de cómo la destrucción de al menos uno de estos puede tener efectos irreversibles.
"Ecosystems are dynamic interactions between plants, animals, and microorganisms and their environment working together as a functional unit. Ecosystems will fail if they do not remain in balance. No community can carry more organisms than its food, water, and shelter can accomodate. Food and territory are often balanced by natural phenomena such as fire, disease, and the number of predators. Each organism has its own niche, or role, to play."*
* From http://library.thinkquest.org/11353/ecosystems.htm
Misión
"Los ecosistemas son interacciones dinámicas entre las plantas, animales y microorganismos y su medio ambiente trabajando juntos como una unidad funcional. Los ecosistemas fallarán si no se mantienen en equilibrio. Ninguna comunidad puede llevar más que sus organismos de alimentos, agua y refugio que pueda alojar. El alimento y el territorio son a menudo compensados por los fenómenos naturales tales como incendios, enfermedades y el número de depredadores. Cada organismo tiene su propio nicho, o el papel que juega. "*
Your task will be to research an ecosystem of the world and develop a presentation describing its inhabitants, subsystems, and the balances between them. You are also charged with explaining the importance of your particular ecosystem in the world system.
Tu misión será la investigación de un ecosistema del mundo y desarrollar una presentación describiendo sus habitantes, los subsistemas, los ciclos y los equilibrios entre ellos. También se espera que expliques la importancia de tu ecosistema en el sistema mundial.

Part 1- Research
Step 1:Each student will choose an ecosystem from the following list:
Pond, Desert, Woodland Forest, Oceans, Marsh Wetlands, Rainforest
(Grasslands, Tundra, and Taiga are optional- see * sources)
Step 2: Students will come to the computer lab to research: Adaptations and Niches,

Proceso
Parte 1- Estudio
Paso 1: Cada alumno elige un ecosistema de la siguiente lista:
Estanque, Desierto, Bosque forestal, Océanos, Los Humedales del pantano, Selva
(Prados, Tundra y Taiga son opcional – mira las * Fuentes)
Paso 2: Después de completar la parte del salón de la unidad, los estudiantes irán a la sala de computadoras:
Adaptaciones y Nichos, Descripción de Ecosistema,
Comparación de los ciclos de vida de las plantas y animales, Redes Alimentarias y Cadena Alimentaria
Adaptations and Niches: Choose 4 plants and 4 animals within your ecosystem and describe their adaptations and Niches. Don't forget to list the source number for each that you used. Use the attached organizer to manage your information. (At Wanke these are in the Wanke Lab Shortcuts folder/5th grade/Ecosystems.) Adaptaciones y Nichos:
|
Ecosystem Description Use the websites and books to find a description of your ecosystem and to find where this ecosystem is found throughout the world. Print this organizer to manage your description information.(At Wanke these are in the Wanke Lab Shortcuts Folder/5th grade/Ecosystems.) Don't forget to record the source number of your information. Open the map template and color in the location of your ecosystem. (Remember you will have to draw in a complete closed shape within your continent to be able to fill it.) Descripción del Ecosistema y Ciclos:
|
Comparison of Life Cycles of Plants and Animals: Use websites and printed material to compare the life cycle of an animal and a plant within your ecosystem. Use the attached Venn Diagram to organize your information. (At Wanke these are in the Wanke Lab Shortcuts Folder/5th grade/Ecosystems.) Comparación de los ciclos vitales de plantas y animales: Utiliza los siguientes sitios de red y los libros para comparar el ciclo de vida de un animal y una planta dentro de su ecosistema. Usa el Diagrama de Venn para organizar tu información. (En Wanke se encuentran en Wanke Lab Shortcuts Folder//5th /Ecosistemas). |
Food Webs and Food Chains: Use websites and printed material to create both a food web and 2 food chains that can be found within your ecosystem. Use the attached powerpoint to design your own using clip art of animals and plants in your ecosystem.
Redes Alimentarias y Cadena Alimentaria: Utilice los siguientes sitios de red y / o libros para crear tanto una red de alimentos y 2 cadenas de comida que se puedan encontrar dentro de tu ecosistema. Usa KidPix para diseñar tu red y cadena alimentria de animales y plantas en tu ecosistema. |

You may choose to .
Before giving your presentation, use the self check evaluation to make sure you are done.
Part 3- Presentations
Students will present their findings to their class. During presentations, students will keep notes on an organizer on each of the ecosystems to be used as study sheets later. At the end of the presentation, students will score presentation using a peer rubric.
In addition to the Self Check evaluation and Peer Project evaluation, your teacher will be evaluating your project from your presentation. She will use one of the rubrics below:
It is also beneficial for you to evaluate the whole research process to determine things you have learned from the whole research process. To do that you need to use the attached self evaluation of the research process.
Congratulations! You have just helped your Earth by finding a deeper understanding of the delicate balance between the ecosystems, their systems, and inhabitants. Because the very existence of our planet depends upon the knowledge and actions of its inhabitants, the more you understand about its workings, the more likely you are to help in needed solutions to environmental issues.
