How is it possible that they are moving?
Geologists think that this is due to wind and mud but wind can’t move stones which weight as much as human. Some people think that this happens because of  freezing water at night in winter, which creates ice sheets.
Widespread winds in Death Valley are able to move the stones.

INSTRUCTIONS ON HOW TO USE IT:
This Excel game is to be used in Math classes as a help-to-understand tool for the students. It contains several types of functions (y=ax; y=ax2+b; y=a log x +b, etc), one in each sheet. The user will be able to choose a value for “a” and “b”, and the function will be graphically represented, always contrasted with the basic function of its type (y=x, y=x2, y=log x, etc), so that the student has a graphic approach to mathematical analysis.INSTRUCTIONS ON HOW TO USE IT: This Excel game is to be used in Math classes as a help-to-understand tool for the students.
