I love this website — The Power of 10s and our place in the universe is put into perspective through a series of photographs that begin 10 million light years from the universe and then ‘move through space towards the Earth in successive orders of magnitude until you reach a tall oak tree just outside the buildings of the National High Magnetic Field Laboratory in Tallahassee, Florida. After that, begin to move from the actual size of a leaf into a microscopic world that reveals leaf cell walls, the cell nucleus, chromatin, DNA and finally, into the subatomic universe of electrons and protons.’
If you are looking for something that will trigger the "Aha!" moment in students, this site is sure to do it. There are a number of videos about power of 10 that cover this- but something about the simplicity of these images that really resonates with students.
Do you have any "Aha!" websites, videos or video clips that always work with students? Post them here!
