In this Flashcard Friday episode of Math! Science! History!, Gabrielle explores how everyday choices can make a real difference for our oceans. From reducing single-use plastics to supporting sustainable seafood and climate-friendly habits, this episode uncovers the math, science, and history behind ocean conservation, and the powerful impact of small changes.

Plastic pollution isn't just a problem for sea turtles and coral reefs, it's a problem for us. Every year, about 11 million metric tons of plastic enter the ocean, leaching chemicals and breaking down into microplastics that end up in fish, sea salt, and even human blood. But with awareness, advocacy, and action, we can help turn the tide.

Three Things You'll Learn:

  1. The science behind ocean resilience ,  how oceans regulate Earth's climate and what happens when that balance is disrupted.
  2. What plastic really does to marine life ,  and the startling evidence of microplastics in fish and even in human systems.
  3. Practical steps you can take today ,  from rethinking single-use plastics to supporting legislation and sustainable brands.

Are You A Charlotte?

Are You A Charlotte?

In 1997, actress Kristin Davis’ life was forever changed when she took on the role of Charlotte York in Sex and the City. As we watched Carrie, Samantha, Miranda and Charlotte navigate relationships in NYC, the show helped push once unacceptable conversation topics out of the shadows and altered the narrative around women and sex. We all saw ourselves in them as they searched for fulfillment in life, sex and friendships. Now, Kristin Davis wants to connect with you, the fans, and share untold stories and all the behind the scenes. Together, with Kristin and special guests, what will begin with Sex and the City will evolve into talks about themes that are still so relevant today. "Are you a Charlotte?" is much more than just rewatching this beloved show, it brings the past and the present together as we talk with heart, humor and of course some optimism.
