Population Boom

Today we joined forces with our Monday third graders and investigated an interesting connection between the sediment problem from last week and the mountain lion hunting occurring in the area. Students played a game to simulate the fluctuation in the deer population with and without predators. They found that mountain lion hunting in the area reduces predators for deer and their population is able to experience booms and crashes. On these booms, they overgraze and reduce ground cover resulting in more erosion than usual.

Turbidity

Today students considered another factor that may be causing problems for fish in Gray Area.  With logging an active business in the area, some of the rivers were looking a little dirty.  Students used secchi disks to determine the clarity, or turbidity, of the water in the various lakes and rivers in the area.  They then examined the sediment files to understand the effects of erosion and high levels of sediments on the organisms living there.

We also enjoyed participating in the Pathfinder Challenge, completing a self-reflection, and soaking in some sun with Listening to Crickets.

Acid Rain Continued...

We've used our research skills to uncover the solution to our curious acid rain test results!  Although the rain over the entire Gray Area is acidic, only some of the waterways are unhealthy for fish due to pH.  Students found that part of the Gray Area has large amounts of limestone that neutralize the acid and make the water livable for fish.  They also discovered that the Gray area acid rain problem is largely cause by cars and trucks, clearing the Toy Factory as a prime suspect.  We also spent time discovering possible solutions to the acid rain problem.

Creativity was also a focus.  Students used originality and design thinking to develop a perfect hat to help our friends the Ats who are plagued by pesky gnats!  Take a look at some of their clever ideas!

We also did some reflection and systems review as students completed their field study packets and shared some favorite take-aways.

Also, we enjoyed Sandstorm, our special class visitor!

Jones Gap Field Study

We had a wonderful learning experience at Jones Gap!  Students explored the river and forest systems of the park.  They were able to use field guides for plant and animal identification, conduct several water quality tests, and understand the important interactions between the two habitats. Thanks to all our wonderfully behaved students and fantastic chaperons!
