When Yadina finds turtles crossing the bike path in the park, she becomes very worried about them - what if they get hit by a bike? Or a trike? She wants to help them stay safe, but what can she do? This problem seems way too big for her. To the Secret Museum! Our heroes go back in time to meet an expert problem solver: Golda Meir. They find Golda in the midst of a big problem herself: a bunch of the kids at her school don't have access to the books they need! This is another toughie. But Golda, undaunted, comes up with the idea to hold a community fundraiser to get money for the books, showing Yadina that she should tell people when there's a problem so you can solve it together.
