Our teachers use sodium metal as a demo only.But when I purchased ours last year I had to fill out paperwork,like a licence,the principal had to sign it,before they would send it.

oh my goodness petal.
You can buy agar powder from science supply australia for $72 for 500g and $29 for 100g.If you need nutreint agar we just add vegimite to the normal agar powder

Julie that doesnt sound fair at all. The director general has just posted a letter on our intranet stating that "staff members who are excluded from their school ( WITH SWINE FLU )will not suffer a loss of pay" This policy should also stand for your dilema I'll be watching this space for u...

we allow our 7-10's to use the scalpels but in groups, one tray per desk (10 desks) and im helping by wandering around the room watching the little petals disect.
If I see a problem I call the teacher.
Matchstick I loooove these smilies!

thanxs for the tip. I will be there with bells on.
I hope he is well prepared!!
