Free streaming video that shows the actual fossils from an ancient sea in the middle of Indiana. Put the mouse on highlighted sections of the rocks and a depiction of the fossil comes to life along with a brief summarization of what kind of fossil it is and how it lived. I really liked this program because it shows how different our world was millions of years ago, and the fact that the program animates whichever fossil you choose, brings the past to life. It would be a great resource to use when teaching biological evolution (3-LS4).

Exceptional website with multiple resources for teaching various lessons on evolution...30+ links to individual pages with everything from PPT presentations, handouts, assessment tools, photos, and lab projects. May be the most complete place for a teacher to go to get everything he/she needs when putting together a lesson.

This is a great lesson on various visual illusions used to engage and intrigue students, all raising the question "Why is this an illusion?" With interest piqued, students are engaged to answer this question about the T-illusion, proposing hypotheses to explain what makes it an illusion, then designing simple experiments to test those hypotheses. This is extended to a look at natural illusions, and how science effectively reveals their reality.
