Data and observations from each of our visits to BEEC's vernal pool are being recorded below. Feel free to add a post if you have any questions or comments about our field work.
Friday, June 8, 2012Deb Pierotti's Oak Grove 3rd grade class visits BEEC to learn about vernal pools
|First, the kids prepared for their expedition by running up and down the grassy hill|
Joan lead the class on a walk through the woods to one of the vernal pools at BEEC. She also supplied the kids with equipment for exploring the plants and animals in the pool (magnifying glasses, buckets, nets, field guides, thermometers, etc).

Orly's third graders from Academy School visited the vernal pool last week. Here are a few comments about what we did and what we saw:

NewBrook School with Pat Branley's and Miss Heather's 1st and 2nd grade students:
Our classes went to visit BEEC and to learn about the vernal pool. We saw the slide show and there were pictures of the different stages of a vernal pool. We also learned about indicators of a vernal pool. They are the wood frog, fairy shrimp, and mole salamanders.
|Here we are being fairy shrimp!|
|With our lab set up, we are ready to start collecting!|
|Hiking to the vernal pool.|

The vernal pool was wet. I noticed lots of leaves at the bottom of the vernal pool.I noticed a tadpole and frog eggs. I noticed bloodworms, but they don't suck blood and they are not worms! They are a kind of larva. We found a habitat made of leaves and little pieces of wood.
We took a hike in the woods. It was fun. We saw chipmunk holes and chipmunks in the woods, but not in the vernal pool!

Thursday, March 22, 2012:On this exceptionally warm March day the vernal pool was full of life. We saw both Jefferson salamander and wood frog egg masses. We also saw wood frogs mating, and we even saw a Jefferson salamander in the vernal pool by the big rock on the east side of the pool. It was crawling about on the leaf letter in the pool. In the picture to the right, you can see how much larger and lighter in color the female wood frog is than the male.
Thursday, February 2, 2012:Orly's third grade class hiked through the woods to the vernal pool. On the way there we saw some mysterious tracks. Could they be from a fox? We noticed that the ice at the edge of the vernal pool was getting thin. We could see where Emily's class had walked along the edge but we couldn't walk there this time. While we were there we found some interesting seeds which we brought back to the classroom to study. We can't wait to go back again.

Wednesday, January 25, 2012:
Emily's class visited two aquatic habitats at BEEC.
Here's what we observed about the pond:
- There are tracks across the pond.
- We see bubbles!
- It's round.
Here's what we observed on the trail:
- Trees have mostly now leaves.
- There are animal tracks of all sizes.
- We didn't sink in because of our snowshoes.
- We think we see coyote tracks, bunny tracks and one huge track off of the trail.
- Maybe there's a bear den.
- There are small brown nut shells with spikes, like natural velcro. Maybe these are Beech nut shells?
Here's what we observed at the vernal pool:
- It looks like a skating rink.
- There are tracks on the ice.
- The broken tree looks like an archway.
- There are branches that recently fell on the ice.
- There are dog tracks in the snow.
- Nolan saw bunny tracks and showed them to everyone. Then lots of people saw rabbit tracks and fox tracks - and fox scat!
- There's a big stone wall.
- The piece of wood looks like the water was higher.
- Animal tracks go over the ice. There is a blue thing wrapped around a tree.
- There are leaves and sticks frozen and sticking out of the ice.
- The water's shaped like a bean or raindrop vs. the pond which was a circle.
- Are there a couple of ponds?
- We're wondering what the aquatic environments look like when it's warmer and are there any animal sleeping nearby?
