Justin and Brian take a break during water testing. |

Laura explores the stream bottom while Darren heads up a chemical water test in the foreground. |
| Getting macroinvertebrate samples can be great fun. |

The Stream Dance of the Macros: it's how the little guys get into the net. This was one of the best quality macroinvert samples done in over a decade at Beall High School |

The proof is in the net!!!! |

Working the macroinverts to make sense of the data. This was a superb sample. |

Dissolved oxygen test. |

Tyler, Megan and Chuck test pH. |
| Water testing - nitrates = 0; phosphates = 0; pH = 7.5; dO = 7: iron = 7; sulfates = 40. Macroinverts indicate excellent water. |

Students observed cycling of nutrients by decay on the forest floor, fungi, seed log decay, snags, and the processing of wood and leaves in the stream by macroinvertebrates. The carbon and nitrogen cycles at Monroe Run can be compared to the cycling in the aquaponics system in the classroom where fish waste is used to grow plants and bacteria are an important cycle factor.
