We did rats at school. I wasn't vegetarian back then.. but I still didn't like it very much. I was interested in biology and I stayed to watch, although it broke my heart when I saw the rats with their bloodied noses.
People really are disrespectful, some people made their rat dance or something.
Seeing the real thing and being able to touch it and follow the system is better than seeing pictures, but whilst there are videos and pictures available I think it is horrible to kill an animal just to show a bunch of kids. Ya, you're teaching them but come on, in highschool how many of those kids will care and take it in and then use the information?
We worked in pairs and had a rat to each pair.
In Tafe it was .. slightly better. They used their own rats that were due for culling regardless, so they didn't die for the exercise. Although they are bred for the purpose of the course which is a bit iffy. Though they do have a good life and are humanely killed.
Anyway, the teacher ended up only using one rat and doing it herself so we didn't have to do it or use any other rats. Which is better I think. Save it for those who want to become surgeons.
This reminds me of E.T with the frogs in the jars. I love that they get let out and saved.

YAAAY!
