| Fifty years ago, James Watson and Francis Crick announced to patrons in a Cambridge pub that they had just discovered the secret of life. Their discovery was that the DNA double helix explained how cells divide and develop. Yet it was not enlightened genius alone that propelled Watson and Crick toward this fundamental revelation. In addition they were building on the work of other scientists and a fortuitous (and un-acknowledged at the time) collaboration with Rosalind Franklin, a British X-Ray crystallographer, was of crucial help in this great achievement.All 50 Secrets of the Sequence videos have an accompanying classroom-tested lesson that encourages students to further explore the video topics. Each lesson includes background information, state and national science standards, discussion questions and answers, teacher notes and an activity that will ensure a hands-on, "minds-on" experience.
