Ever wonder where all that dino poop went? Whether ants use toilets? Whether plants talk and, if so, how their “language” evolved? And what would you guess is the survival function of stinky feet? These are precisely the sorts of questions about which national science journalist Rebecca Coffey wonders. Family Friendly Science is a collection of science articles written by Rebecca and intended to get families talking together about science. You can find FFS on the radio, here on the web, and soon to come on YouTube.

Some of the FFS articles are written with high school students in mind, some for middle schoolers, and some for littler kids. Use the category drop-down level at left to search by grade level or by category of science. (But remember. At Family Friendly Science, all posts are appropriate for whole-family family discussions about science.)

Europe’s earliest professional warriors?

5a56640f199c46e8f5b28af9404a3d7dSome 3,200 years ago—about 100 years before the fabled sacking of Troy—an epic Bronze Age battle for a bridge in what is now a marshy area of northern Germany was fought. Looking for all the world like extras in Lord of the Rings, thousands of soldiers clad in skins, protected by shields, and attacking with clubs, swords, and bows and arrows converged. Men and battle horses alike died in an apocalyptic fight. Despite its scale and brutality, the battle was eventually lost to history. (Writing wouldn’t become common in that part of the world for another 2,000 years.) But in 1996 an amateur archeologist found, sticking out of a riverbank, an arm pierced by an arrowhead. Soon after, the first few crumpled bodies and skulls were found. In 2009 and 2015 careful excavations of only about 1/10th of the dig unearthed about 10,000 bones. A geomagnetic survey in 2013 found evidence of a 120-yard-long bridge. And this August journalist Andrew Curry describes in Science the archeologists’ emerging picture of the earliest known episodes of large-scale violence in European history and of an approach to war that seems to have gone way beyond local clan fighting local clan. The soldiers in this battle used weaponry that was both standardized and uncommonly heavy, suggesting that mobilizing and training the men was itself an enterprise. DNA from the soldiers’ teeth point to ancestries that varied widely. Evidently the soldiers were not farmers; they were members of a professional, pan-European warrior class.
