Introduction

In this Unit, you will clean up trash along the ocean floor to save the Mangrove Reef! For more information about this Coral Reef Cleanup, watch the video below.

The goal of Coral Reef Cleanup is to collect as much trash as possible with your ocean cleaning robot before its batteries run out, and without damaging the delicate coral around the reef. To collect the most trash, you will need to create an algorithm. An algorithm will allow your robot to navigate around the Mangrove Reef and collect additional trash as it randomly falls. 

In this Lesson, you will learn about the first component of an algorithm: sequence. Sequencing commands will help you collect even more trash as you apply your skills in the Code section.
