Microplastics & Me — October 6, 2021, 5PM Eastern


Microplastics—the broken down byproduct of plastic items we toss out every day—are choking our oceans. But Massachusetts high school student and author Anna Du is on the case. She witnessed this problem first hand with microplastics floating up on the beaches near her home in Boston, MA. Even though a middle schooler at the time…..Anna decided to do tackle this pollution problem head on.

Join Anna as she shares her account from her book, Microplastics and Me, of how she went from worrying about the environment to designing award-winning solutions as well as laying out a framework for would be environmentalists to follow. You will learn the:

  • Science of the microplastics problem
  • Engineering and design of her ROV
  • Use of research and data as part of the solution
  • Tips and techniques for winning at science fairs
  • Roadmap of how you can become an environmental conservationist

Anna’s interest in saving the ocean from plastics pollution helped her place first in the Massachusetts Science and Engineering Fair and win the 2021 Sanofi Genzyme award; become a nationally recognized Broadcom MASTERS finalist; attend the International Science & Engineering Fair, win scholarships and travel the world; be featured on WGBH, Disney Huffington Post, FOX 25 News, Fast Company and Smithsonian Magazine.  And, she has a 10 episode TV series, in its second airing, that you’ll hear all about during her Tumbleocity.

Her goal is to spread the word not only about the dangers of microplastics in our environment, but also about the ways to mitigate this problem. She is looking for young people everywhere to join her in helping solve world problems that will face their generation as they get older, and to prevent further damage to the climate and the environment to help preserve Earth for generations to come. Want to join her in this good fight?

Sharks At Your Service — August 5, 2021, 5PM EDT


Sharks are at the very top of the list of animals that fascinate children and adults alike, but they are usually depicted as ferocious and destructive hunters. These negative portrayals miss the point that these top predators play an essential role in maintaining the health of the world’s oceans. Sharks at Your Service highlights the positive side of sharks—as the ultimate service providers in the sea!

Join author Mary Cerullo as she explores many of the different kinds of sharks and rays and the roles that they perform in the sea — some of which even resemble jobs that humans do on land. She will use exciting video, whimsical illustrations, and dramatic photographs by the award-winning underwater photographer Jeff Rotman. Mary hopes you will see some of the things we have in common with these sea giants, and maybe it will make you want to work to protect sharks from their top predators: us!

Mary Cerullo teaches and writes about the ocean. She has written 23 books on ocean life for children, including City Fish, Country Fish (a School Library Journal Best Book of the Year), Octopus: Phantom of the Sea (a Junior Library Guild Selection), Giant Squid: Searching for a Sea Monster (an Outstanding Science Trade Book selection by the NSTA and the CBC), and The Truth About Great White Sharks (IRA Teacher’s Choice Award).


Audience:  for ages 7+

Date:  August 5, 2021
