One of my fave's is about the blue ringed octopus and neurotransmitters. It's very much 'edutainment'.

The scenario....

I am walking along the beach/rock pools, and I step on a rock or something sharp. I think nothing of it.

After a few minutes my speech becomes slurrrrreedd. I am having trouble balancinggggg wwwwoooow.

I decide I need to go to the surf life savers, but I am having trouble walking and I can't really see where I am going. I try to tell my friends buuuullllt Iiiy canmt taaaawng properly. My leennngs doooonn work nnn I am shoort of brreatth.

I am blind now, and laying on the beach paralysed. I can't move, cant speak, can't breathe, and my heart has stopped beating.

I have been bitten by a blue ringed octopus. It has 2 pouches of toxin next to it's beak (yes, they have a beak). One is to subdue prey, and the other is for defense and is deadly.

There is no cure for the deadly - no shot or pill.

The only thing that can save me is if I receive 12 - 24 hrs of heart massage to keep my blood circulating until the toxin wears off.

I hope my friends are up to it.

The Blue Ringed Octopus is found around the most populated parts of the Australian coastline. It is the size of a golf ball.

In the general discussion there was a conversation about an on-line Science Fair - has anybody got ideas how this might work and/or are there examples of this out there somewhere already?

I visited latenitelabs and it seems great! Before I try to buy it for my class is there any way, other than demo, to see the real potential of this software?
thx for all

Hello Britt,

I teach chemistry to freshmen and sophomores at a community college. Some of my most successful science lessons are in the laboraotry. And not just hands-on labs, but virtual labs too. I teach an online chemistry lab using LateNite Labs. They are a company specializing in creating a virtual laboratory. Here's the link: www.latenitelabs.com

Hi Mike,
Which area of science do you teach in? I am a year 7 -9 maths/science teacher in Australia. I also teach VCE environmental science. What are some of your most successful science lessons?

Hello All,

It's good to see we have a Science group. Classroom 2.0 is a great environment for exchanging ideas.
