And, unlike taxes, lotteries are voluntary.

my power is on, but my place of work has been without power for the last 3 days. I'm still getting work done...just at a somewhat more relaxed pace.

I am a private school teacher and we explored the use of iPads in high school and middle school. We basically concluded that the cost exceeds the utility of the device. We want to teach students to be content creators, not simply consumers. And the iPad isn't nearly as suitable to this function as an equivalently priced laptop. Instead, we're moving to model of standardization of software for ease of exchange of files and setting standards for student computers that will connect to the network. We're trying to look at software that is licensed to allow all students to run it on personal laptops since, being a private school, many of the laptops on campus are not school-owned. This is moving in the direction where we would expect all students to have their laptop with them every day. Of course, one real sticking point is that very few rooms have the power outlets to let an entire class of students run plugged in and most laptops don't have battery for a full day of classes (which is one of the few things that was really attractive about the iPad).

But, in general, "at will" employment means they do not need to give a reason for termination. Once they start down a path with specified reasons, then they have other rules which come into play.

That said, to the OP: get a lawyer. The lawyer can spell out what specifically applies in local law.

Yes and no.

Chemistry at this level, like most high school courses, should also be about learning to be an integrative thinker and relate ideas in one area to another. This include computer skills that might be learned in one class and applying them to another; connecting ideas from biology, chemistry, and physics; realizing that the problem solving skills of math translate; learning to apply the writing skills from English and history classes in other contexts.

Believe it or not, this is not something that every student does for themselves. It is something that most need to learn. And the teachers that I work with usually spend quite a lot of time trying to help with this issue.

While not chemistry class, students can and do make use of tools like this in high school. For instance, the SMART program.

As a high-school teacher, I have used LaTeX in physics class. It might seem like it has a steep learning curve at first, but the students catch on very quickly. It can be used both in reports and in presenting material to each other online. MediaWiki, phpBB, and many other tools for interaction have the ability to use TeX...which makes presenting equations far easier than hacking things together with HTML codes. Also, depending on the order of the chemistry and biology courses in your school, you may want to, as someone recommends below, look at PyMol or another 3D molecular viewer. There are also a number of decent Java packages that don't a local installation to run (which depending on how good your tech support is about installing new packages might be easier if the available computers already have Java installed).
