This book contains 13 labs using consumable materials purchased from local stores including Analysis of a Mixture, Paper Chromatography, and Coinium (using pennies to demonstrate half-life). There are two versions of each lab, one with a ten-question conclusion and one with directions for a full lab report. This way the teacher has the option! Each lab is two pages to allow for one two-sided handout.
During the next few weeks, I will talk about some current research going on in the science community. I realize that during the school year it’s very difficult to keep up with such topics, so this would be a quick snapshot of what's being pursued.
I was aware of the large amount of plastic-based garbage in the world’s oceans, and I’m pleased that one clean-up method is being investigated. Here are a few articles:

There is a report available but it’s 527 pages! If you’re interested:

There are concerns about this method as stated here:

I think that it is important to examine and question proposed clean-up methods – we don’t know if there would be unintended consequences. I’m encouraged that a test patch of clean-up is being attempted in 2016.
I’d love to hear from you about further research developments – write when you can!
