Hour of Code: AI For Oceans – Learn About Machine Learning and Ethical Use of AI

Curriculum developed by For grades 3+. Released under the Creative Commons license.

Computer science is about so much more than coding! Learn about artificial intelligence (AI), machine learning, training data, and bias, while exploring ethical issues and how AI can be used to address world problems. Enjoy’s first step in a new journey to teach more about AI. When you use the AI for Oceans activity you are training real machine learning models. 

Lesson 9: AI For Oceans

Tutorial Summary: First students classify objects as either “fish” or “not fish” to attempt to remove trash from the ocean. Then, students will need to expand their training data set to include other sea creatures that belong in the water. In the second part of the activity, students will choose their own labels to apply to images of randomly generated fish. This training data is used for a machine learning model that should then be able to label new images on its own.

Checking Correctness: This tutorial will not tell students whether they completed the level correctly. It is possible to skip through the different parts of the activity quickly. Encourage students to watch the videos, read the instructions, and try different things along the way. At any time, they can share their findings with you or a classmate.

Purpose: This tutorial is designed to quickly introduce students to machine learning, a type of artificial intelligence. Students will explore how training data is used to enable a machine learning model to classify new data. Students should have a positive experience during the tutorial and more importantly should be motivated to keep learning computer science.

The Hour of Code is a global movement reaching tens of millions of students in 180+ countries. Anyone, anywhere can organize an Hour of Code event. One-hour tutorials are available in over 30 languages. No experience needed. Ages 4 to 104. Code.orgĀ® is a nonprofit dedicated to expanding access to computer science in schools and increasing participation by women and underrepresented minorities. Our vision is that every student in every school has the opportunity to learn computer science, just like biology, chemistry or algebra. provides the leading curriculum for K-12 computer science in the largest school districts in the United States and also organizes the annual Hour of Code campaign which has engaged 15% of all students in the world. is supported by generous donors including Amazon, Facebook, Google, the Infosys Foundation, Microsoft, and many more.
