I just wanted to let you know how much serious, Science fun we had last day of term.
We had a teacher who was a vet nurse do the dissection so she knew a lot about it all. We had many guest students, teachers and staff come to observe as everyone was so fascinated.
Definitely a worthwhile science activity!!

At this time of year it can seem like the entire curriculum is falling down on top of you. It’s a few weeks until the end of the year, you’ve got content to finish teaching, revision to fit in, exams to write and mark, graduation ceremonies, reporting…. the list is endless and you still have to turn up for rostered playground duty.
It is very easy to decide not to squeeze in an extra activity and nobody would blame you. But sometimes something special is just what the school needs at this time of year.
We had a couple of very large porcine uterus arrive unexpectedly. I couldn’t tell if they were pregnant, but they were certainly bigger than anything I had seen before. One school made the time in their day to include a dissection of the uterus and a bovine penis specimen as well and the response was fantastic.
As word spread about the impending spectacle other classes asked to come. When the reception staff were forewarned about the delivery they asked if they could watch too. On the day questions were thrown thick and fast and every single person in the room went away with at least one piece of information about their reproductive system that they didn’t know before. Can you imagine the conversations at dinner tables all around the coast that night? “What did you do at school today, son?”…..
Are you doing reproduction in your curriculum this term? Mr Vivi’s all ovary it. Don’t let other suppliers testis you with delays in supply, he has you covered there too. Further more, you won’t have to drive your uterus to the abattoir, he’ll send it all right to your door. 😉
Sometimes something so unusual appears that we can’t help ourselves and we have to cut it up ourselves. This heart presented us with one of those times.
On the outside it was rough textured and the tissue was very soft. It was easy to pull a piece off with your fingers.
On the inside the right side chambers had a few differences to a normal heart. The right atrium and ventricle were both very circular in shape compared to a typical heart. The pectinate muscles and the trabeculae carnae were almost non-existent so inside the right side chambers was very smooth.
There was a layer of tissue on the outside that was obviously different to the rest of the myocardium.
The pericardium was separate and appeared quite normal, as did the rest of the pluck.
At the outset we thought we might have a parasitic infection and were a bit disappointed to find no evidence of it when we opened up the heart. Perhaps it was a congenital defect or a viral infection that caused it? If anyone has any insight into what we had then we’d love to hear it. Drop us a line here.
