VERY new to jQuery-UI!

Hello my people!
 
I am about to start using the jQuery-ui and downloaded it about an hour ago but it is not working. I specifically wanted to try the datePicker and accordion widgets to experiment but they are both not working. I beleive the problem is that I connect to the regular jQuery through Google by using the following scripts:
 
 <script type = "text/javascript"
         src =  " http://www.google.com/jsapi">
 </script>
 
 <script type = "text/javascript">
 //<! [CDATA[
 
       google.load("jquery", "1");
   
    //]]>
   </script>
 
I have the jQuery-UI locally. Could it be the problem? I have several files that downloaded at once and unzipped them all but they are still not working. I suspect the problem is the way I am connecting to jQuery or the way I am linking the jQuery-ui source files. I am utterly confused and need help! Thank you all!
