The very busy spider....

We spied this very busy spider in one of our trees today.  While a little shocking to see, we quickly learned that it is a common garden spider.  While intimidating looking, it is not poisonous. One of the things unique to its web is that there a zigzag pattern in the middle.  We also learned that it sits heads down in its web.  All these things this spider showed us.  Such fun finding science in our own yard!
