These devices can be used in so many different lab settings. Students can discover hands on learning about water samples in streams, ponds, and oceans. Physics can be investigated with pressure and force probes.
Chemistry can use the organic and non-organic detection probes.
There are so many things a teacher can demonstrate with these units. Graphical Analysis is good software to use for data analysis because it comes in Mac and PC versions and a schoolwide license is very inexpensive. I needed some data for a lab I was doing in Earth Science. I looked up some facts on WRAL's homepage and it was a blast. I have made up a neat mole lab to devise the conceptwithout telling the kids anything.
