CONVERSEMOS (1 de 2):
¿Cuál crees que era el problema en la pecera?
CONVERSEMOS (2 de 2):
¿Qué harías para tratar de ayudar a los peces?
CONVERSEMOS:
¿Por qué no se mueren los peces en un estanque si el estanque no tiene un filtro para limpiar los desechos que están en el agua?
CONVERSEMOS:
¿Se te ocurre alguna manera de BAJAR los niveles de dióxido de carbono en un estanque?
Pista:
¿Qué seres vivientes NECESITAN dióxido de carbono?
1. DIBUJA: Haz un dibujo de las relaciones que existen en el ecosistema de un estanque. Para empezar, escribe "plantas," "descomponedores," y "animales" en una hoja. (No pongas las palabras demasiado cerca, porque escribirás cosas entre ellas). Después dibuja flechas y escribe las cosas que las conectan.
2. REVISA: ¿Incluiste flechas para los desechos, los nutrientes, dióxido de carbono, y oxígeno en tu modelo? Si no lo hiciste, hazlo ahora.
3. ESTO FUE LO QUE NOSOTROS HICIMOS: Este es nuestro modelo de un ecosistema, pero hay muchas maneras de dibujarlo y el tuyo puede ser diferente.
If you need a natural stopping point!
Teachers: If you are short on time, this is a good stopping point. You can play the Big Fish ecosystem game in a future session.
If you’ll be playing another day, have each pair of students clip their cards, their Fish-o-meter, their pointer and their worksheets together with a binder clip.

In Part 1 of this activity, students will work in pairs. In Part 2 of this activity, students will work in groups of four to play the Big Fish game. Homeschool students can work on their own for Part 1, but will need a few friends in order to play the game.
Part 1 (building an ecosystem) takes 10 to 15 minutes. Part 2 (playing the game) takes at least 20 minutes.
You may want to divide this lesson into two sessions, stopping after Part 1 and continuing with the game at a later point. If you plan to do the activity in two sessions, the group game begins at Step 12.
Divide your materials into two piles.
For Part 1, you’ll need:
For Part 2, you’ll need:
If you want to do Part 1 and Part 2 on different days, you can keep materials organized by having each pair of students clip their cards, their Fish-O-Meter, their pointer, and their worksheets together with a binder clip at the end of Part 1.
When you are doing Part 2, start by giving each pair of students their materials from Part 1. Then have pairs get together to make groups of four and distribute the additional worksheets.
