Help With School Project Involving Water Pump

Hello,
I am doing a group project at school where we need to create an electronic stuffed animal using the Sparkfun Inventor's Kit and code it with Arduino. For our project, we want to make the animal's eyes light up with LED lights. We also want to make it squirt water out of its nostrils. In order to do that, we bought this pump from the Sparkfun website. We figured that it would come with all the supplies necessary in order to make it work, but it did not. We are having trouble trying to figure out what we need to do to get it to work, and how to code it. No one in our group has any experience using Arduino or with the Inventor's Kit. Any help would be greatly appreciated.

Thanks!!

This is a digital design class, not a computer science class. Our professor doesn't tell us or teach us how to code. Is there any way you could possible guide us and help us learn how to code the pump? We were thinking that since the pump connects to the switch that all we need to do is figure out how to code the switch to turn on and off. Is that correct?

Turning anything on is just the same as turning an LED on so see this:-

A water pump is the same as a motor so see this:-
