NCLab is a public cloud computing platform for K-12 schools and homeschoolers, that provides engaging self-paced interactive courses in various STEM subjects.

The electrostatics elasticity modules look interesting!

The interactive educational modules on this site assist in learning basic concepts and algorithms of scientific computing., Each module is a Java applet that is accessible through a web browser., For each applet, you can select problem data and algorithm choices interactively and then receive immediate feedback on the results, both numerically and graphically.

Compares strategies used by students in a competition. Some used math, some didn’t. Their scores varied WIDELY!!

From the author, Tony Forster:

“Here I look at some basic mathematics ideas: number, equality, addition and functions to see how the visual representations match the mathematics concepts and might aid understanding”

This might be a stretch for young people to use to learn about using computers to do simulations but maybe a teacher could use it to demonstrate using computers to model fluid flows:
