Marie Tharp loved science, but in the mid-20th century when she joined the lab at Cambridge University in New York, she wasn't allowed to go on research boats: everyone knew that women at sea were bad luck. Instead, Tharp dove into the information that her colleagues brought back and started drawing a map of the ocean floor. Slowly, her map grew, revealing something even bigger than the Atlantic: a ridge, right down the middle of the ocean! That ridge not only changed what people thought about the ocean floor, but it also proved the new theory of plate tectonics, changing our understanding of how the planet changes over time. This exuberant picture book biography by the author of Shark Lady is a tribute to perseverance and the power of thinking differently!
"Water is the first medicine, Nokomis told me," this little girl remembers. It is an element that connects all of us, and all the other living creatures on our planet. So when our water is threatened, this girl takes a stand to defend it: she becomes a water protector. Ojibwe author Carole Lindstrom and Tlingit/Haida illustrator Michaela Goade were inspired by the many Indigenous-led movements to protect this precious resource for this Caldecott Medal-winning book, but they also remind readers that this issue is goes beyond a single community, country, or race: "we are all related," they point out, and if we take action, we can all be water protectors.
