Windy days

So when we first moved here to where I live now, we had five trees but over time, one by one they’ve all gone. The first one lost a large branch in the wind, the next one died due to disease, then one split apart and fell on the house, while the next one (which was leaning towards the house) had to come down and finally, the last one was dying a slow death before being taken down.

One concerned me most about the last one was actually all the strong winds we’d had lately, which finally leads me to this article entitled “The Ocean’s Biggest Waves Are Getting Even Bigger” by Rafi Letzter over at LiveScience.

The article in fact got me to thinking that I’m wondering if the winds on land have also gotten stronger. I have to say, I don’t remember having wind advisories like we had this spring. Meanwhile, we’re planting our first new tree in a week or two. In the fall, I hope to plant at least one more.

All trees break equally

So a long time ago, back in the days of Leonardo da Vinci and Galileo, many tried to quantify how well wooden beams would resist bending. It wasn’t until 2009 however, following a huge storm called “Klaus,” over in France that scientist began to realize that most trees tended to snap when winds reached about 94 miles per hour (151 kilometers per hour).

Check out all the details in the article entitledWhy Trees Everywhere Break at the Same Wind Speed” by Tia Ghose over at LiveScience. Me, I always worry any time the winds reach over thirty miles per hour. Good to know.

DIY science projects

Tonight I thought I would share a couple of articles on DIY science projects that you can make at home. With my kids still liking to have night lights, this first one is a  project I thought I might try to do this weekend. The article (and video) are entitled “Glowing Algae Makes for a Living Night Light” by Megan Treacy over at Treehugger.

The other article is also very enticing and one I think I want to try but maybe over the summer. It’s entitled “How to Make a Small Backyard Wind Power Generator” by Jaymi Heimbach, also at Treehugger.
