This site has multiple simulations on it, but the free trial only give you FIVE MINUTES for each simulator per day. Free trial lasts 1 month.
This site uses what I have chosen for criteria and searches for sites that it has compiled. Shows you one at a time...hit STUMBLE to get it going.
Go to Gapminder World. This is a great site for real world data - the graphs are pretty cool too!
Creates pictures from solving problems and connecting the dots. Cute.
Great toon maker, but kids will have to make their own account. They can save them, email them, edit them. It's nice, but quite a bit going on for them to play with.

Folks, I have exciting news for you tonight. I have just resurrected 5 TI-83+ calculators from the dead on my kitchen island this evening. After a short surgical procedure, I am happy to report that all five calculators are alive and doing well.
You see, although my school can afford fancy new red turf for our football field, we don't seem to have the funds to replace any of our aging calculators. I've been nursing my classroom set of 30 ever since I inherited them shortly after being hired at "Paradise" high school.
In case you don't know how to restore dead calcualtors, here are three steps to try. Try the steps in order. Sometimes I get lucky and step one will work and I won't need to use the other steps.
1. Remove all four batteries. Press and Hold the [ON] key for 10 seconds. Then put the batteries back into the graphing calculator and turn on. May need to readjust screen’s contrast again.
2. Remove one of the AAA batteries. Press and hold the [CLEAR] key. While holding [CLEAR], reinsert the AAA battery and then turn the calculator on. The calculator should display the message "RAM Cleared". Release the [CLEAR] key and then press it one more time to remove the message.
3. Remove one of the AAA batteries. Press and hold the [DEL] key. While holding [DEL], reinsert the AAA battery and then turn the calculator on. The calculator should display "Waiting...Please install calculator software now". Follow the instructions for the TI-83 family or TI-84 Plus family to reinstall the calculator operating system.
If steps 1-3 don't work, it is time to resort to step #4 and that is what I did tonight.
4. Remove all of the batteries including the round lithium battery for 5 minutes. After the 5 minute period, reinsert all of the batteries and turn the calculator on. Adjust the contrast if necessary.
Now, drum roll please. . .. . Here are my calcualtors after surgery! Tonight I was successful in restoring 5 calculators that I thought I was going to have to scrap!!!

Doesn't really describe them much - mostly screen shots of the sites
Lots of different slide shows about how to use different technologies and what is out there.
