6th Grade Science - Inventions - Bridges





We're spending the first 10 weeks of this years studying the inventors of the 19th century. After the invention of the steam engine, railroads came along. And with railroads came the need for better bridges. So today I had the kids bring in their balsa wood bridges - which we broke (if they wanted to do so!). One held over 17 pounds of lead weight. Pretty good for only one week to build (usually we spend weeks going over the forces on bridges before we have a competition - this was a bit more informal.)

I think we'll do some bridge building this year. I know Jon will enjoy it.

Both of your science classes look and sound like a slot of fun.
