Realistic life sized model of the embryo/fetus at 6, 8, 10, 12 and 14 weeks are sequenced next to the 16 week fetus within a model of the womb.  The model illustrates the size, physical features and positioning of the embryo/fetus, so it is a great graphic instructional aid on reproduction topics.

Each Model Activity Set consists of a 24" x 18" markable model of durable vinyl and an activity guide. The activity guide introduces background information, and has teacher-developed activities. The guide contains a glossary, a key to the model, color transparencies and a blackline master.
