 the next physical model that you'll be making for your lab class again you just need to take a picture, not a full blown video like I'm doing it's a little bit hard to get everything arranged but you're going to take some sort of round object to represent your earth. I've got a paper plate here and then I've got my ball that I'm using and I'm just going to get it aligned so that between my light source my ball and my plate I can see that I've got the physical alignment to cause an eclipse and then you would take a picture of that configuration. If you have any questions or difficulties let me know. Notice I am not looking for perfection this is not a perfect shot either but it is showing you the general positions and getting you used to understanding things in 3D.
