This animation from the Faculty of Education at the Chinese University of Hong Kong nicely illustrates how a heart works. You can watch how blood moves through various chambers as well as seeing how it matches to an electrocardiogram.

The future figured prominently in my reading this week. Janet Clarey questions the future of physical classrooms based on Elliot Masie's question of Classrooms of the future. She asks: do we need physical classrooms for learning. While the comments to her (and Elliot's) post range significantly, the concept of classrooms as we know them is clearly changing.
As trends in learning and technologies become more divergent, and thinking becomes more important, the walls of the classroom move out. Classrooms and the web. Blogs and LMS. Collaborative learning and blogging.
A few additional resources: Learning technologies and schools of the future (.pdf)...and predictions for 2008 (coming in a bit late - it's cheating if your predictions aren't made at the end of the year or within the first few days of the new year.
Taken verbatim from the Students 2.0 blog:
They get it. Period.Twenty-first century education won’t be defined by any new technology. It won’t be defined by 1:1 laptop programs or tech-intensive projects. Twenty-first century education will, however, be defined by a fundamental shift in what we are teaching—a shift towards learner-centered education and creating creative thinkers. Today’s world is no longer content with students who can simply apply the knowledge they learned in school: our generation will be asked to think and operate in ways that traditional education has not, and can not, prepare us for.
As we move into a world where outsourcing, automation, and the ability to produce a product, physical or intellectual, at the cheapest cost, become the cornerstones of our rapidly evolving global economy, the ability to think critically is no longer enough. The need to know the capital of Florida died when my phone learned the answer. Rather, the students of tomorrow need to be able to think creatively: they will need to learn on their own, adapt to new challenges and innovate on-the-fly. As the realm of intellectual accessibility expands at amazing rates (due to greater global collaboration and access to information), students of tomorrow will need to be their own guides as they explore the body of information that is at their fingertips.
Visualizing huge numbers can be very difficult. People regularly talk about millions of miles, billions of bytes, or trillions of dollars, yet it's still hard to grasp just how much a "billion" really is. The MegaPenny Project aims to help by taking one small everyday item, the penny (on this site they use the US penny), and building on that to answer the question: "What would a billion (or a trillion) pennies look like?" 
a link, a resource, a "new" idea, or some encouraging words for the group of educators we're working with outside of Philadelphia today. And feel free to let others know they can contribute as well.
So far there is a good annotated collection developing

Writers In Electronic Residence Launches 20th.Year - Jan. 14Linking Canada's Writers with Canada's Schools
Imagine having Wayne Gretzky assess your stick work, or Elizabeth Baird test your butter tarts. Then imagine that their advice was part of a free exchange of ideas among other students, teachers, and the pros, culminating in everyone joining in a practice hockey game or sitting down to eat the final creation. This captures the reality of Writers In Electronic Residence, where the coaches are prominent Canadian writers, working online wth students and teachers in elementary, middle and secondary classrooms across Canada--Iqaluit to Toronto, Vancouver to St. John's.
WIER's winter term will open with its usual two-week "introductory period" on January 14, 2008. Space is available in each of WIER's online writing programs--elementary, middle school, and secondary school levels. The term will run until April 5.
