How I Use It
Intro lab that covers qualitative vs. quantitative data and unit conversions. I have students look up their favorite animals and compare some of the measurements in metric measurements. They do unit conversions on these measurements.
This is a great search engine that can do many things that a standard Google search won't do well. On the other hand, it's not as deep as Google. If you type in "elephant" for example, it'll give you the taxonomy, measurements, and some pictures, but not much beyond numerical facts.
