Friendly Chemistry is a truly unique approach to teaching introductory chemistry. Used by home schoolers and charter, public and private school students world-wide for over ten years, Friendly Chemistry presents what is often considered an intimidating subject as a genuinely fun, enjoyable experience. Whether you're a high-school aged student needing a lab science course or a "non-traditional" student looking for a refresher course to help you prepare for an upcoming entrance exam, Friendly Chemistry can help you accomplish your goal in a "painless" way! If you do have aspirations of a future in a science field, Friendly Chemistry can give you the solid foundation you need to succeed in subsequent courses. Friendly Chemistry was written using simple language and a host of analogies to make learning (and teaching!) chemistry easy. The chemistry concepts presented in Friendly Chemistry are NOT watered-down. The concepts are just explained in ways that are readily understood by most learners. Coupled with these explanations is a host of teaching aids, labs and games which makes the learning concrete and multi-sensory. Students find the course fun and painless. Parents often comment, "I wish I had had this when I was taking chemistry. Now it all makes so much sense!" Friendly Chemistry covers the same topics taught in traditional high school chemistry courses. The course begins with an introduction to atomic theory followed by discussion of why the elements are arranged the way they are in the periodic table. Quantum mechanics comes next using the acclaimed "Doo-wop" Board as a teaching aid. Next comes a discussion of how atoms become charged (ionization), followed by an explanation of how charged atoms make compounds. The mole is introduced next, followed by a discussion of chemical reactions. Stoichiometry (predicting amounts of product produced from a reaction) is treated next followed by a discussion of solutions (molarity). The course is wrapped up with a discussion of the ideal gas laws. Please note that this is the STUDENT WORKBOOK. This volume contains worksheets and lab report pages which accompany the student edition. There is no text or other explanatory material in this workbook. The student edition must be purchased separately.Shipping Notes

Basic mouse that works - - for now.
Size: 1 Pack, Style: USB Receiver, Color: Blue
I ordered this mouse (in blue) to replace the recently deceased exact same model that I've used for the past 2 or 3 years. I like the simplicity of the M185 mouse and mostly the best bang for your buck! I caught this one on sale for less than a ten-spot, so I thought, "why not."
I'm hoping that this one will last a bit longer than my two previous M185 models, that averaged about 3 years each. This model seems plagued by a short life span and is predisposed to mysteriously and suddenly dying, without any obvious symptoms or warning of any kind - - you're working and clicking along, going about your day, when suddenly the cursor on the computer screen freezes and that's it. Nothing, zero, nada. Funny thing, I'm very careful not to abuse or drop the mouse, and keep a fresh battery installed and watch for leakage and all that stuff - - they just stop working, and I assume it is caused by some sort of inherent electronic fault in the circuitry of the previous M185's. Due to my loyalty to the brand and model (and since it was on sale) I decided to give it one more shot. They say that "third time's a charm".
I like the fact that the M185 is simple and uncluttered with extra buttons that I would never use for my purpose, which is simple web-browsing and the occasional text document production. The feel is solid, not heavy, but not cheap feeling, either. I'm used to the shape of this mouse, which to me is quite comfortable for long sessions, another reason why I kind of wanted to stay with this model. The buttons have an audible "click", which doesn't bother me at all, and the wheel moves smoothly and also has a clicking operation (which I rarely ever use). The overall surface of the mouse has a matte finish, but like my previous models I'm sure it will eventually wear shiny spots where my fingers reside and will attain a more "well-used" look in time. Connecting it was a breeze, too. I just plugged the dongle into a spare rear usb port of my desktop, and the mouse connected instantly, no problem. The dongle can be stored safely inside the battery compartment, so you can take the whole thing out of the house if needed for use elsewhere. The speed of 1000 dpi seems just right for my purposes. The one I ordered even came with its own AA Duracell battery, which I wasn't really expecting. This mouse also enters "sleep mode" when you don't use it for a while, and I can't say how many times I've got up and left it on all night. And that's not hard to do, as I'll explain next.
The only real negative to this mouse is the absence of any easily visible status indicator of it's on / off switch. The rear housing of this mouse is matte black, including the tiny switch where you turn it on and off with your fingernail, with only a very faint "on" lettering (also black), and very hard to see with my aging eyes. The laser is not lighted or visible when on, also adding to the confusion, especially in a darkened room. So, as a workaround, I took a tiny drop of green paint and placed it down inside the switch slider to visibly help indicate the "on" position, and likewise a dot of bright orange for the "off" position. Many of Logitech's more expensive models (and a few other manufacturers) include this color-coded switch indication. I guess for the $$, they had to cut corners somewhere - - a minor complaint.
In summary, this is a good basic mouse that works - - let's hope that this one will last longer than its two predecessors.

Dependable, Reliable

As advertised. Logitech, best mouse for your hard-earned cheddar!
It’s not that the (years) old Logitech mouse failed in any operational way, it just got that gummy, sticky surface texture that’s impossible to remove. While shopping for a replacement I noticed an off-brand mouse/keyboard combo and thought, “hey, 2 for 1”…mistake. All was well for about three weeks, long enough that when the gremlins arrived I didn’t immediately associate the new hardware. For the purposes of this discussion, gentle reader, know that I run legacy (what I affectionately refer to as, “Lazarus”) builds. Rigs that started life running Windows Vista/7, died, and that now, resurrected, run 10 and 11, and all that that implies. So, when a mouse started stuttering, of course I thought it was a gremlin in the machine, right? I spent more days than I am comfortable sharing with you pouring over processes and background apps, and registry trims…before Accam’s Razor suggested I eliminate the mouse as a variable. Changing the battery was ineffective, but when I swapped in the ooold Logitech…Yahtzee/Bingo/Booyah…smooth and precise…butter! All I needed was a new Logitech mouse.
So, if you’re here you likely are having mouse issues of your own, or you just need one that works…this is it!

Nice and a great value.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
Hey, it works well. Just plug it in and you are ready to go. Only issue, minor, no light or color coding on back to indicate on or off.

Smooth and ergo nice mouse.
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
I needed this little thing quickly and got it within 2 hours of ordering. It was only an extra five bucks to get it now. Would have burned more than that in fuel. Works exactly as I would have expected. Perfect.

Simple and efficient
Size: 1 Pack, Style: USB Receiver, Color: Swift Grey
This is a dandy little item. Easy to use straight out of the box, No fancy bells and whistles.but why should a mouse try to replicate commands that are on the laptop?
