When she finds it, she lays her eggs on the plant, so when each egg hatches, the baby caterpillar can feed on the milkweed leaves. The milkweed plant then provides the perfect protection as the caterpillar turns into one of nature's wonders, a chrysalis, before transforming into an even greater wonder: a monarch butterfly. And once the newborn butterfly soars away, the milkweed seeds fly away on the wind and start this cycle over again. The exacting prose and jewel-toned illustrations echo the harmony of monarch and milkweed in this carefully researched book, explaining one of nature's most spectacular displays in a refreshingly simple manner.

     In Elkhorn Slough, an inlet on the California coast, seagrass grows healthy and strong in the shallow water. This healthy seagrass baffled marine biologist Brent Hughes. The scientist expected this estuary to be overrun with algae, causing the seagrass to die. Why was the seagrass thriving? As Brent investigated, signs pointed to an unexpected player helping to keep the seagrass healthy: sea otters! What do these top predators have to do with an aquatic grass at the opposite end of the food chain? Brent's discovery gave scientists insight into the delicate balance of ecosystems. Follow science in action as Brent conducts the research that led to this major discovery.

    Because she was going to study him, she decided to call him Alex--short for Avian Learning EXperiment. At that time, most scientists thought that the bigger the brain, the smarter the creature; they studied great apes and dolphins. African greys, with their walnut-sized "birdbrains," were pretty much ignored--until Alex. His intelligence surprised everyone, including Irene. He learned to count, add, and subtract; to recognize shapes, sizes, and colors; and to speak, and understand, hundreds of words. These were things no other animal could do. Alex wasn't supposed to have the brainpower to do them, either. But he did them anyway.Accompanied by Meilo So's stunning illustrations, Alex and Irene's story is one of groundbreaking discoveries about animal intelligence, hard work, and the loving bonds of a unique friendship.

    He just liked to collect frogs. Tyrone’s interest in science led him to Harvard University, and though he struggled at first, he found his calling in the research lab of an amphibian scientist.Meanwhile, scientists discovered that all around the globe, frogs were dying. The decline has many causes, including habitat loss and disease. Tyrone discovered that the most commonly used pesticide in the United States, atrazine, may also play a role. Tyrone tested atrazine on frogs in his lab at Berkeley. He found that the chemical caused some of the male frogs to develop into bizarre half-male, half-female frogs. What was going on? That’s what Tyrone wants to find out.

    Now, in Plant a Pocket of Prairie, Root and Bowen take young readers on a trip to another of Minnesota’s important ecosystems: the prairie.Once covering almost 40 percent of the United States, native prairie is today one of the most endangered ecosystems in the world. Plant a Pocket of Prairie teaches children how changes in one part of the system affect every other part: when prairie plants are destroyed, the animals who eat those plants and live on or around them are harmed as well. Root shows what happens when we work to restore the prairies, encouraging readers to “plant a pocket of prairie” in their own backyards.By growing native prairie plants, children can help re-create food and habitat for the many birds, butterflies, and other animals that depend on them. “Plant cup plants,” Root suggests. “A thirsty chickadee might come to drink from a tiny leaf pool. Plant goldenrod. A Great Plains toad might flick its tongue at goldenrod soldier beetles.” An easy explanation of the history of the prairie, its endangered status, and how to go about growing prairie plants follows, as well as brief descriptions of all the plants and animals mentioned in the story.With Betsy Bowen’s beautiful, airy illustrations capturing the feel of an open prairie and all its inhabitants, readers of all ages will be inspired to start planting seeds and watching for the many fascinating animals their plants attract. What a marvelous transformation could take place if we all planted a pocket of prairie!

    Harry was a veterinarian. But he was also a soldier in training for World War I. Harry named the bear Winnie, short for Winnipeg, his company’s home town, and he brought her along to the training camp in England. Winnie followed Harry everywhere and slept under his cot every night. Before long, she became the regiment’s much-loved mascot. But who could care for the bear when Harry had to go to the battleground in France? Harry found just the right place for Winnie while he was away — the London Zoo. There a little boy named Christopher Robin came along and played with Winnie — he could care for this bear too! Sally Walker’s heartwarming story, paired with Jonathan Voss’s evocative illustrations, brings to life the story of the real bear who inspired Winnie the Pooh.

    They defied the prejudices of the time. And they blazed a trail for generations of women to follow.What does it take to be an astronaut? Excellence at flying, courage, intelligence, resistance to stress, top physical shape — any checklist would include these. But when America created NASA in 1958, there was another unspoken rule: you had to be a man. Here is the tale of thirteen women who proved that they were not only as tough as the toughest man but also brave enough to challenge the government. They were blocked by prejudice, jealousy, and the scrawled note of one of the most powerful men in Washington. But even though the Mercury 13 women did not make it into space, they did not lose, for their example empowered young women to take their place in the sky, piloting jets and commanding space capsules. ALMOST ASTRONAUTS is the story of thirteen true pioneers of the space age.
