Your search on Google Scholar should show a link to EndNote under each record. If it is not there, then you need to set your Google Scholar preferences to allow this. Click on the symbol and then choose Google Preferences
Scroll to the end of this page, where you will need to change the settings to show links to import citations into...EndNote..then save preferences 
Now as you identify useful records you can download them into your EndNote library but only one at a time....
The record from Google Scholar will be fine for essays but you may want to copy and paste in an abstract and/or keywords directly from the article or from another database - Google Scholar works best for journal articles but mistakes do creep in so it always pays to check the final record
