Instead of simply reading an answer, young scientists build, test, measure, explain, troubleshoot, and improve. Inside are 48 original missions across six units: Forces & Structures; Motion, Energy & Sound; Matter & Materials; Earth, Environment & Living Systems; Data, Design & Technology; and Capstone Engineering. Every mission is organized for active discovery, with: - a curiosity-starting question and real-world context- a clear objective, materials list, and safety check- a prediction prompt before the test- four practical steps to follow- a data table for observations and measurements- troubleshooting guidance when results do not go as planned- an explanation of the underlying mechanism- an improvement challenge, key vocabulary, real-world connection, and exit ticketThe activities are designed for flexible use at home, in a homeschool setting, in a classroom, or with an adult mentor. Many begin with familiar materials, while the questions encourage careful thinking rather than guesswork. Readers are invited to compare evidence, notice patterns, revise designs, and connect everyday experiences to the science and engineering behind them.This is a book for young people who do not stop at 'What happened ' They also want to ask 'Why ', 'How do we know ', and 'What could we improve '.…
