MakerBay Team worked with the students of the Lingnan University (their background are social science, business, art) on a Plankton and Plastic Ocean Expedition. Over 1-day boat trip in Sai Kung (Hong Kong), students learnt about

  • Citizen Science
  • Biology and Biodiversity
  • Bamboo spitting
  • Scientific Tool Design
  • Rapid Prototyping


  • Team working
  • Leadership
  • Creativity

This project is recommended for grades 4 and up.

Why Study Plankton and Plastics?

Do you know around 70% of the oxygen on earth is produced from phytoplankton in the ocean? Planktons play an important role in maintaining the earth's equilibrium. They are also the food of fish and filter feeders, so it is also the foundation of our ecosystem.

Watch this video to find out more about planktons and how scientists are studying them. And also participate in the PlanktonPlanet citizen project to help mapping plankton around the world.

We planned to take sample from 2 different routes. One near the coast (Red line), another one further away from coastline (Blue line). Each route have 5 checkpoints. On each boat, several MakerBay Team members using to measure the distance, and track speed.

This is a great project! I love seeing the different net designs and collection results. :)
