RocketLit
aka BirdBrain
RocketLit offers leveled science articles with corresponding assessments. Articles range across science topics and provide the same content and vocabulary words at seven levels, from grades 3–4 through 11–12. Vocabulary is bolded but must be defined through context. Articles at higher levels are longer and more complex. Accompanying quizzes (multiple-choice, optional free-response) also vary with level. The site grades multiple-choice responses immediately, providing students with a score (but no question-specific feedback), and quizzes can be retaken.
How Do I Use This Tool?
A Common Sense Media Review
Upper-elementary and middle school teachers using a flipped approach may be able to use RocketLit for individualized, independent content reading. Assign articles to be read online from home, or print them for individual kids. Then use online assessments to help gauge initial understanding. You may want students to take notes or provide them with a vocabulary sheet. Pay attention to kids' comments to help ensure they're grasping the "right" ideas, and definitely continue the learning with your own classroom/lab experiences.
