evolution  

How can you prove that a match or mismatch between an organism and its environment could lead to its evolution or extinction?

Hi Jayanthi,
If you include the entire URL (including the http and www part), the link will open up in another window and take us all directly to the site.

Yes Carla, the URL is www.sciencenetlinks.com/interactives/evolution .
This interactive is a game where the setting of the environment could be changed from green to orange and all shades in between. The object of the game is to see which bugs (green or orange) survive the predators at a particular time. The children would leave the buttons at one setting and print screen 10-15 times and counting up the bugs at any given point. The following could be the what the data looks like :

# of Green bugs # of Orange Bugs
18 3

14 2


32 6


After the data is generated by the students, they plot it in excel. This is a good launching pad to discuss a number of topics in evolution including ideas like 'Why the number of orange bugs is dwindling when the background is green?' or 'Why the chances of endanged species multiplying again becomes a remote possibility in nature?'

I find that there a number of questions regarding evolution which children come to grips with only if they are exposed in a number of different ways to the concepts or else it becomes very difficult to understand them.

This URL is the initial data generating tool. I plan to include another URL with real data for children to work with. I am still searching for this site.
