Every student had a specimen, a preserved animal or a plastic model. Remember, folks, we are also specimens, in the eyes of nature or the almighty. [To view a 200K version of this photograph, click here.]

These red painted eggs came from a special party held after the lesson. [Top-secret.] [May I take this opportunity to say thank you once again to all those students who initiated, orchestrated and participated in the amusing function. That day was gone, yet it is still in our mind, fresh. ]

The lovely foetus, like the earthworm, has a body cavity too. That cavity is known as the coelom. It allows space for tissues to grow, contains a liquid (= coelomic fluid) to facilitate the exchange of gases, and wastes between the body surface and internal organs. It is also a hydrostatic skeleton, a kind of cushion, or mechanical buffer.

For some unknown reasons,

students are often fascinated by

 skeletons, be they

artificial, real or imaginary.

In fact, some children books

abound with skeleton motifs.

The feeling might be similar to

that towards the dinosaurs.

They are terrible yet safe.

They are extinct,

so they can pose no harm.

What a funny last lesson ? Before I started my lesson, they were already opening up cabinets, and  hunting for all sorts of models and specimens for their photographic session.
