lots of places you could go with this. Draw what band structure would look like for taller or narrower tower.

Great idea for formative assessment. Schedule automatic posts to the blog, and have kids write comments as their answers.

this is an great post that explains that the speed of light doesn't slow down in materials, nor are charges inside a conductor "shielded" from external electric fields by the surface charges on a conductor.

shared by John Burk on 21 Sep 11 - No Cached

John Burk on 21 Sep 11

This is a great video for demoing ideas about pressure and gas laws, an in particular the how boiling point increases with pressure. Popcorn pops because the water inside flashes to steam and expands. If you put the system under sufficient pressure it won't do this … until the pressure is released, and all of the popcorn pops at the same time.

A provocative piece from a really great biology blogger on how the microscope "e" lab and learning all the parts of the microscope kills interest in biology. Instead, have students start by observing real, live, big things under a dissecting scope or a magnifying glass first.
