If you work at a museum or a park or home school your children, you can use the program.

I've had students begging teachers to let them play the game.

We want people to become educated about our water resources, and we believe that when we teach kids, kids will then teach their parents.

If you're sick, stay home. If your children are sick, keep them out of school.

Also, make sure your children are challenged – make sure they are bringing more and more rigorous work home.

I think it's an avenue of educating children that just are not able to succeed in traditional home-school roles or in the public schools.
