I always love when Spring arrives because we start physics topics in my eighth grade physical science class!  Don’t get me wrong—my first love is chemistry and I have a Master’s degree to prove it—but there’s just something about physics in the Spring.  My students delve into the topics of speed and momentum with great gusto.  Two highlights?  Rolling marbles down a ruler and designing their own Hot Wheels experiment.  Not only are these students exploring some key physics topics, they are ALSO getting a chance to dabble in engineering:  a great combination!

The Physics of Bridges


How Bridges Are Built | Educational Innovations Blogby Lior Zitman

Bridges have changed greatly over the years.  Thanks to advances in building materials and machinery, building a bridge is now more precise than ever before.

Nevertheless, all these modern marvels come down to a few simple physics principles.  Our technologies may evolve, but some things—like physics—never change!

Every bridge, regardless of its form, must constantly balance the opposite forces of tension and compression.  How these forces work together is what makes each bridge type unique. Read the rest of this entry »
