Exploriments and getting lost on the internet

I got lost this morning on the internet. It was Google's fault. I was actually doing some research on iPad apps and projects for middle school when I wandered over to Common Sense Media and their suggested list for apps which got me to thinking about Windows apps since my students use Microsoft Surfaces and iPad apps don't really help us. And I thought to look around for apps that my students could use which made my train jump to another track but long (and I am rambling here) story short I have hit on the website Exploriments. Way cool!

I take this from their site:
Exploriments are simulation-based interactive learning units for enhancing conceptual understanding in Science in an experiential manner.

Totally out of my mental world but there are virtual experiments and demonstrations that even I (a math phobic) enjoyed doing and my brain did not shut down as if often does when presented something involving an algebraic equation. I just completed a nice little activity on atomic weight. I especially like how the site will tell you what you got wrong and explain how you get the correct answer. Nice. 

Exploriments has a collection of iPad apps that unfortunately are not free but are very inexpensive and probably would be worth the money for your students to benefit greatly.

The website, however, has more interactives that you can access for free. I did create a free teacher account (you will need an email address to register and students will need one also) but some of the Exploiments are locked. It asks me to register or login to access but no luck. I've sent a message to them so we shall see. However- the rest of the site is open and free to use. This site definitely deserves a look/see.
