Foregrounding scientific vocabulary, these integrated lesson plans invite students to research worms in order to create a classroom habitat. Students are first introduced to inquiry notebooks and then use them to record what they already know about worms. Next, students observe the cover of a fiction book about worms and make a hypothesis on whether the book is fact or fiction, and then check their hypotheses after the book is read aloud. Next, after an introduction to related scientific words such as hypothesis, habitat, attribute, predator, and prey, students conduct and record research and findings in their inquiry notebooks. Once they have gathered the necessary information, students plan and build a worm habitat, which becomes the springboard for further scientific exploration, observation, and experimentation.
