"Citizen science--when scientists need observations from ordinary people to build a database and complete research--is hot right now in many science fields. Climate change, migration patterns, plant growth, population changes, and more require an all-hands-on-deck approach to data gathering that allows even young readers to participate in scientific pursuits. But how? This book, written by a veteran teacher, answers all the questions children have about how, where, and why it's so important to engage in citizen science. Accessible language and web resources throughout the text point young readers in the right direction!"--,Provided by publisher.
