I created a model of fetal development through wax and dye on an egg. The top of the egg cycles through the beginning stages of pregnancy from a fertilized egg through a 2 and 4 cell stage to a 16-cell stage. The second cycle on the egg shows the development of the blastocyst and the final cycle shows the fetus from week 4 to week 20. This represents a normal pregnancy. I also separated these stages in order to compare a normal pregnancy to an ectopic pregnancy. An ectopic pregnancy typically lasts until around week 6 to 8 until it could become fatal to a mother. This would be at the beginning of the second cycle shown on the egg. I made this distinction between the different levels (from top to bottom on the egg) to show that an ectopic pregnancy would not make it to the third level.

This is my feeble attempt at an illustration of the normal heart with directional arrows to explain how the blood flows through and returns out to the body.
Osteogenesis Imperfecta
Osteogenesis imperfecta is often known as brittle bone disease. It is a rare genetic condition that effects the collagen that is suppose to provide support.
