A sip of Merlot perhaps?

Why not!

The amount of content on the web is growing exponentially - and this includes materials that can be shared and may help students with their learning. 

There are many places that you can search for content to add to your materials - a few of which I have put as a permanent link on the right hand side of this blog - but there is one that has been seriously under-utilised and that is MERLOT - Multimedia educational resource for learning and online teaching. 

Merlot offers a well-established peer-reviewed database of learning objects for sharing: http://www.merlot.org 

For example -  I searched for Merlot for materials by category - selecting Science and Technology > Engineering on the left hand side. There were 595 entries. You can search within this category if you like. There are simulations, case studies, tutorials, quizzes and more.

The first link in this engineering browse was a 'Classic' - MecMovies - by selecting 'Go to material' I arrived here  http://web.mst.edu/~mecmovie/ . MecMovies takes learners step by step through various concepts in Mechanical engineering such as torsion, sheer stress and strain. The community had rated it as 4 and a bit stars and it was included in the personal collection of 17 Merlot Members  (which is pretty good). 

There was also a 2 minute movie from the author http://taste.merlot.org/Videos/MecMovies.html that explains what Tim Philpot was getting at when he designed the tool and how he determined that it was making a difference for his learners. 

So why not give Merlot a go and see what it might be able to offer you?
