Inquiry Starters from WVIZ, Cleveland

Here's a link to a video series put together by WVIZ Ideastream, titled "PSI: Physical Science Investigations".

Each video comes in multiple segments, with corresponding background info, data sheets, and T-Charts for making predictions and variable analysis.

Definitely worth a look, especially in the context of instigating inquiry within student learning experiences:

Some of these I'm sure you've demoed in your ooms, as I did mine while teaching science. Performing a live demo of these segments would surely have more instructional impact, where possible.
