Here, we studied and answered Here, we studied and answered questions about what we wanted questions about what we wanted to learn. We composed studies to learn. We composed studies of the wildlife, soil, vegetation, of the wildlife, soil, vegetation, and stream. Our group also did and stream. Our group also did a study of air pollution with the a study of air pollution with the “Burlington Trailer”.“Burlington Trailer”.

Soil!

The focus of this portion of our presentation is on the different soil types found in the East Woods region. The purpose of our investigation was to compare and contrast soils in different locations around the region and pair these soils with the vegetation around them. Our data were gathered by digging several soil pits in separate locations, using a soil auger to take soil plugs, taking the pH of the soils, and later recording the different types of vegetation surrounding the pits. All of these data were later compared and contrasted to draw conclusions about different areas in out field site.

A:A: There are only small animals that use this area as their habitat because the ground cover vegetation There are only small animals that use this area as their habitat because the ground cover vegetation is limited.

Air Pollution!Air Pollution!

On Tuesday, H.A.M. traveled to the “Burlington Trailer”. This is a station that monitors air quality aspects in the city of Burlington. Below is a link to the website for all of the air quality information. Also, there is a second link that assists viewers in getting air quality updates sent to their cell phones or email:

H.A.M. was also informed of a “haze cam” that is set in Burlington.this camera takes pictures of the haze status that is happening over Lake Champlain. This is something that visitors to the website can see as well.
