A quick shout out and chemistry-themed valentine's card goes to Richard Byrne, of FreeTech4Teachers.com, who featured Learn Chemistry in a recent blog post.

Free Tech 4 Teachers is a popular, and frequently-updated, blog that does exactly what it says on the tin. As every teacher knows free (or at least cheap, robust, powerful, and simple to use) technology is always in demand - which is why we hope Learn Chemistry will only grow and grow in popularity; all our resources are free to download and use.

And with Valentine's in mind, I thought I'd put a little sugar in your life, with the help of Learn Chemistry and Chemspider.

Happy Valentine's!
