If you are in middle school science I'm sure that you know about Loose in the Lab! Right now they are having a fantastic sale on some of their books, so I thought I'd share. The books are only $3 and so I, of course, bought one of each of them. They are full of quick demonstrations or labs that are on specific topics. Click on the book to go to the sale!
