The little squirmy things you see here are called American glass eels. Glass eels are the topic of one of the podcasts we have been working on. They are a very mysterious creatures, out of everything scientists have learned about these fish, they have only scratched the surface of the lives of The American Eel. They are being closely watched since their numbers have decreased and their case is being reviewed to see if they should be put on the threatened species list.
The Eel project is a program where groups of citizen scientists, college students and high school students collect and count glass eels every spring using net and trap devices and then release them at the tops of those streams. This program has a dozen different sites throughout the hudson river and is doing incredible work to collect data on the number if incoming new born eels every year.
The American Holiday Thanksgiving is around the corner. A typical thanksgiving dinner involves a turkey. But where did the turkey come from? The turkey came from north America and was introduced to the pilgrims by the natives when they settled. They ate it together at the first thanksgiving in 1621 and the tradition stuck since.
Channelization is a man made way to channel creeks or streams the way people want them to go. Cities use this so they can put roads and buildings on top of where the stream or creek would have originally went. This can be a negative thing because it effects the stream habitat. A way cities try to make this more natural is taking out the concrete and putting back more natural materials like rocks and dirt.
Underground streams are streams that are found underground. They put them underground for a number of reasons such as to allow cites to expand over the streams. This has positive and negative effects to the stream. A negative effect is the organisms that live in the streams don’t get any sun light which kills the algae that feeds some of them. A positive effect is they can build streets and buildings over the stream through the city.
" Do you know what a Watershed is? How about a permeable surface?"
Those are some of the questions we asked during an after school program we took part of at Krieger elementary school, Poughkeepsie Ny. November 2012. We worked with the 3rd, 4th, and 5th grade children. We did many activities to try and teach them about the environment. The kids really enjoyed doing activities because it was much easier learning the material. One day we did something called “World In A Bottle” which is where students can build their own terrariums in a bottle. Another day we did “Branching Out” in this one, we made our own model of a watershed. After building the model, we observed the water from high points to Low points, then place a “pollutant” anywhere in the watershed and watched what happened when it began to rain. After we were done, we would ask questions to wrap up the day and to be sure many of the kids were paying attention. We enjoyed our time at that after school program and would love to go back.
You see those gutters on the streets? those are there for Stormwater. Stormwater is water that comes from precipitation and lands on the ground either permeable or impermeable and flows to the nearest storm drain or water body, this causes major pollutions in our major water bodies because whatever is on the streets of a city will get caught in the stormwater and follow it to the water bodies. Some ways to prevent this type of pollution is having a rain garden, a rain barrel, or having your at home gutters flowing into the grass and not on a drive way.
How & Why Do Leaves Change Color?
As we get closer to Fall, trees respond by stopping the food making photosynthesis process and slow the production of Chlorophyll, until they stop producing it altogether then that green color starts to fade. There is so much more to know about how and why leaves change color so for more information look at this link…http://mentalfloss.com/article/31501/how-why-do-leaves-change-color
Beavers are the second largest rodent species. They are known for building dams, canals, and homes for themselves called lodges. They create dams to keep away predators, float their foods and more building material. The North American beaver population rate has decreased from 60million to 6-12million. This was mainly because of hunting for fur, their glands used as perfumes or medicine and many more. Beavers are very useful, but I don’t think we should be killing them. If we keep on doing that, they will one day be instinct.

A flood is when a large amount of water covers a dry land. It can destroy homes, cars, and be very dangerous. A flood can accrue from an over flow from a river or lake. Some floods can happen in a matter of minutes with out warning, but others can take time. One of the most recent floods that just took place was the Colorado flooding. It had about 2million in property damage, and effected about 200 miles south and north of the state. It was a really rare flooding that occurred. If you would like to read more about this flood, you can visit the site below. Or search Colorado Flooding. http://www.weather.com/news/colorado-rushes-repair-flood-damaged-roads-20130923
Cars, are they good for the environment?
