How to load jQuery from a module Drupal 7.x, Garland theme.

I am writing a module that depends on jQuery.  I am seeing that when an anonymous visitor comes by that jQuery isn't being loaded.  How do I load jQuery from my module?

I am not really a Drupal developer.  This is my first module.  I want to maintain Core as is (no hacking) for easy updates and I don't want to change themes from Garland, so I don't really want to edit the theme to force jQuery.

Thanks.
jQuery should be available to you right out of the box in D7 if I remember correctly. But you need to use jQuery(...) instead of $(...). If jQuery is not being included for some reason, try using drupal_add_js().

See Drupal 7 JavaScript API documentation for more information.
