Just noticed a post about this worm simulation in the Educational Wormers Group. It is in German though so I'm not 100% sure what it does. Looks like you can add various kinds of food to the system and it will show you a graph of the baby / adult / etc worm populations. I thought I'd post in the general forums in case there are any folks here who want to poke around and figure it out as a group. I suppose if someone knew german that would be helpful as well.
This is fun even when I don't understand what's going on. Could anyone translate a few of the words under the buttons? There aren't very many. The first time I watched pH go down to 0 (I'm not even sure that's possible!) Needless to say I killed everyone off. I figured out which buttons to click on and keep the numbers up in the green range. A few words would be great. Thanks someone.
