Chemistry 101

Now as I told my daughter a while back, science was never my strong point in school but as an adult, I’ve really come to love it. That said, these two articles are really just going to cover chemistry 101. To be honest with you, I never took chemistry, either in grade school or college.

The article that is focused on grade school is entitled “Chemistry crayon labels add an ‘element’ of playful learning to coloring” by over at Inhabitots. I wish I had those when I use to color.

The second article, focused on the college level, is entitled “New elements recently added to periodic table” by the University of Tennessee. I don’t know what’s there now, so that’s not going to help. FYI,  there will be a quiz next week.

Ode to Sea Salt

With this being the year of the elements (mostly because my date book this year is entitled The Elements) I thought I would post this very nice article on salt. Now while salt not actually an element, it is in fact a compound or combination of elements. So while I wish I were sitting somewhere on a beach in France, here’s the next best thing. It’s entitled “Letters from Paris: Magic Measured in a Pile of Salt” by Elaine Sciolino of the New York Times.

All around us

While these two articles don’t discuss rocks, sewers, etc… they do talk about a couple of  chemicals that are/or were at one time, all around us. The first article, “Magi Would Have a Tough Time Finding Frankincense Today” by Elizabeth Weise at USA Today is on resin, made from the gum of the Boswellia Papyrifera Tree.

While nature’s chemicals sometimes go away, others like those made by man, seem to have a hard time going away such as the ones mentioned in this article entitled “Old Chemicals Are Back in Battle Against Weeds” by Georgina Gustin at the St. Louis Post-Dispatch.

Rain, rain go away….

Well, it did go away just in time for the kids end of the school year picnic. So as school winds down for them (and for me, it wound down last week), lets try to end this work week on a positive note.

Just a couple of posts here kids and getting them outside. The first one was over at the Wall Street Journal entitled “Can Dirt Do a Little Good?” by Melinda Beck. Ivote yes.

To prove this point (okay, this is a little less positive) check out “Rising Levels of Dioxins from Common Soap Ingredient in Mississippi River, Study Finds” over at Science Daily.

Finally, back to the positive. While it’s not really a lot in today’s economy, at least it’s something. Check out how the U.S. Forest Service is getting involved in getting kids out in “U.S. Government Spends $500,000 to Get ‘More Kids in the Woods“” by Warren McLaren at Treehugger.

With the stars out tonight as the skys clear and with an outlook of sunny days ahead, you can bet I’ll be outside this weekend with the kids.

Sunny Days!

Washing dishes

As I stood there washing one solitary spoon with as little dishwashing soap as possible, my thoughts turned to chemicals.  So as I decided to wash the silverware I use at work at home, I thought I would pass on a couple of articles on chemicals. Sounds like fun huh?

First up, these two from the Environment News Service entitled “Toxic Chemical Releases Down Overall, Mercury and PCBs Up” and “Flame Retardant Chemicals Taint All U.S. Coastal Waters“.

Lets follow that up with a couple of old friends from the world of toxics, say hello to DDT  and PCB in “Plastic Resin Pellets: Your New Source of DDT and PCB” by at Treehugger. Where’s Rachel Carson when you need her (again).

Here fishy, fishy

Here are a couple of other articles on our good friend the fish and their role in our place we call home.

First, “Fish Exposed to Antidepressants in the Wild” at EarthSky.

The other one is “Fish ‘an ally” Against Climate Change” by Catherine Brahic at New Scientist.

Thanks to a book I’m currently reading called “Twinkie, deconstructed” by Steve Ettlinger this article over at LiveScience caught my eye. It’s entitled “New Antifreeze Improves Ice Cream“. Scarry!
