Jackson Springs

We went to Jackson Springs Park that was the park that Andrew Jackson camped at a long time ago. It joins with the new riverwalk in Macon. We looked at rocks and I saw a lot of feldspar and granitic type rocks! We sifted the soil to see particle size and used water to press it down further and get accurate measurements! The riverwalk trail is the only in Middle Georgia and it has lots of historic places on the trail. Jackson Springs used to encompass from the park up to the Grey Highway. It used to have a zoo.

Community Gardens!

Anyone who has a garden in an urban environment should test the soil for lead.  It should be known however that community gardens are most likely to be in urban areas. Because of this all community gardens should be soil tested often in order to assure healthy growth and consumption. Since lead can be toxic at high concentrations it is important to realize where it came from in order to know the importance of testing. Lead in urban areas is now prominent due to two primary sources: the lead that came from lead-based paint in older buildings (prior to 1978) and auto-emissions or gasoline. While lead is no longer in gasoline ie. unleaded gas being printed on every pump lead persists in soils for long periods of time. There are many documents that talk about soil testing from a basic to more advanced level. One good resource is the Purdue Horti Website .

Movie Post

I have always been fascinated with the sea and the creatures that live beneath the sea. I found it interesting that one vent with oxygen is enough to sustain a whole colony of creatures. I also thought the adaptations of the animals to be able to see an interact was interesting! This is another video I have seen explaining the area below it.
