In humans:



Gastrulation in Amphibians:

A cartoon animation of the movements of chick gastrulation as we currently envisage them, concentrating on the movements of the lower layer (hypoblast and endoblast) and mesendoderm.

http://www.gastrulation.org/Movie15_2.avi

Time-lapse movie of a chick embryo starting at stage XII/XIII, in which a small group of cells in the prospective forebrain territory has been labelled with DiI. The posterior edge of the blastodisc lies towards the top right. Note the Polonaise movements which begin before primitive streak formation.

High-school level, but I have taught college-level in the past. Right click on the link, then choose "Save target as". This will save the file on your harddrive if you're using internet explorer.
