Sorry for 2 posts in one day, but I thought I'd post some images from our field work today. We've been heading to the Gallinas now every day for about a week to do this last big ecology project.
This is my first year, Higher Level Biology class hard at work in the Gallinas river area just west of campus.
The kids were given the following prompt as their lab: Design and conduct an experiment to survey a biotic component or investigate the relationship between a biotic component and an abiotic component of a river ecosystem.
The rest is up to them. Here's what some of them are studying:
1) stream richness vs. stream flow rate as determined by measuring the number of different species (and # of individuals in each species) of aquatic macroinvertebrates (water bugs)
2) grasshopper population and distribution study using the capture-mark-release-recapture method
3) cattail distribution study as affected by soil moisture content
4) a few other various plant studies and how varying abiotic factors affect plant distribution
5) pocket gopher population study (capture-mark-release-recapture)
Pretty cool stuff huh!?
cheers,
jeff

No wonder you're having a good time..you spend all your time in the creek. While the kids work, teach checks out the trout holes.
