A sense of scale

Posted on Nov 3, 2009 in Interactive Whiteboards, Science Resources, Useful Links | 2 comments

This is an excellent resource for teaching Scale that was shared on Twitter by Graham Linehan last week.

This Cell Size and Scale interactive from the Genetic Science Learning Centre, University of Utah, takes you from a coffee bean down to a carbon atom.

senseofscaleDrahg the slider across the screen to zoom in and out and view cells, organlles, paramecium, viruses and molecules, ending with a carbon atom. It’s a brilliant, clear way to demonstrate  relative scales of objects and would be perfect for Science teachers. View it here

    Not quite as pretty as your example but I have always liked this site for showing the idea of scale and particularly dealing with the size of numbers in standard form:
