The tutorial for the lunar lander is here (download pdf)
This involves creating a yspeed variable and then writing scripts for a motor (which is controlled by the inbuilt Etoys joystick - great feature, which will appeal to kids), for gravity and for the landing process (which works by colour under detection)
