That's pretty much what I have to do. I have come up with about 15 things and was actually looking to do more. Here is exactly what the assignment is. Create a powerpoint presentation showing science that was once taught 30 to 50 years at the most has changed and been updated by new facts and information. The more recent the better. Most notably I did for example Introns are not garbage as increasing evidence is finding uses and valid information of their exsistence. Another one was the big bang theory and what was thought until then. funny thing was this is harder than I thought to find things.
