If you've checked out the Science Spot (and once again, let me stress that if you haven't, you really should), you may have come across an activity called Riding the Rock Cycle.
It's pretty self-explanatory...
Using the provided sheets, you make the dice for each station. Students begin at one station, roll the die and follow the directions, which will lead them to another station (or they might have to stay put). The students use the details of their "trip" to create a comic strip.
But, here's a brilliant idea my mom thought of....
When she made the dice, instead of just having hollow, paper cubes, which are easily crushed and require care to store, she used wooden blocks for the center. 
It takes a little work to figure out the right size to make your copies of the dice. But, once you have it figured out and make the dice by wrapping the paper around the blocks, they'll last a lot longer and you won't have to make new ones every couple of years.
