Another fossil reptile under construction. |
| The Clipbird Lesson |

Jessica explains how the Clipbirds exercise works. |

Students begin "feeding" on "foods" of different sizes. |

Greg tabulates the resulting data on the board. |
| Consequences of Variation |

This walking stick insect assisted in the student-designed experiment. |

Greg prepares to drop the walking stick to see how far it will glide. |

Greg and Jenny measure the glide distance. |

A student enters the data on the board. |

Jenny takes another measurement. |
 |
| Germinating Seeds |

The students prepare to plant the treated seeds of California native plants in the schoolyard. |

A student treats a seed with a chemical in an experiment to see how germination is affected. |

Another group of students prepares its own seed treatment experiment. |
| The Effect of Extinction on the Ecological Web |

A student looks through some of the interactions cards. |

The game begins with each student (organism) possessing a certain number of "resource chips" (beans in this case). |

A student reads one of the interactions cards to see which "organism" gains and which one loses resources. |
| River of Shame |

Students begin drawing businesses, parks, schools, etc. along the river that drains to the Bay. |
