Evidence: how do we know what we know?

leave a comment »

I’ve mentioned the Exploratorium (R) before, but not the full site in detail. I’ll be returning to it again in the future. And tying in with my Evolution of Life post, I came across Evidence: How do we know what we know?

EVIDE

This site uses the origins of humans as a case study to demonstrate scientific process and investigation. There are several high quality videos supplementing the content, section being:

  • Observing behaviour
  • Collecting clues
  • Investigating relationships
  • Finding patterns
  • considering possibilities
  • How science works
  • Can you believe it?
  • Map your knowledge

In the Podcasts and more section there is a little template that you can print out and cut/fold into a useful booklet about fundamentals of scientific process.

Then there is a section called myEvidence, where you can see evidence on a range of subjects other people have ‘mapped’ and you can login and map your own evidence.

The site is Flash driven, so you’ll need to have a Flash player installed and reasonable bandwidth, although there is a low-bandwidth printer friendly version of the site available.

This is a site well worth spending plenty of time investigating.
