This is intended as a lesson in a biology class. The idea is to introduce animation first by getting the students in an earlier lesson in the unit to animate mitosis (which is simpler) using stop motion animation first. This is because they do not need any major software to do this and I have found in the past that stop motion is a good way in to capturing attention.
The meiosis lessons focus on using software to create the animation, so progresses the students in their IT skills as well as their content knowledge. The level of detail that you go into for meiosis depends upon the level of the class. For example, a year 10 student may just show the division of a cell into four daughter cells in steps whereas a year 13 student would need to show each stage (anaphase, telophase etc).
