Animations & Structures

My students have recently been working with building and studying structures in science.  It's been great as we've been looking at those really big structures (Empire State Building and taller) and the smaller ones (beaver dams, etc.).  While not overly complicated, I thought it would be interesting to build living structures; that is, structures that are actively being used (is this redundant?).

Using PowerPoint as our building tool, though it could be any other tool, we built a bridge using piers and decks.  And then--for fun--I had them have a car race over the desk.  The results were impressive.
