Who knew that school trips could be so exciting? The Critter Kids have a knack for discovering adventure and mystery as they travel with their teachers to exotic places to learn about a Native American desert preserve, an archaeological dig amid ancient ruins, a tropical coral reef, and more! And despite unnerving events and unexpected obstacles, the Critter Kids manage to see the humor in their situations and learn from their experiences. Offset fact boxes explaining important vocabulary and reference details—along with other graphic novel-type features—support young readers by linking factual information to the stories. A special reading comprehension section at the end of each story provides additional guidance for reading enjoyment.
