These are science kits that end in a working object rather than a worksheet. The Water Filter Kit builds a filter that actually runs water through its stages. The Robotic Dinosaur Kit includes materials for three separate mechanical builds, a Tyrannosaurus, a Triceratops, and a Brachiosaurus, plus eight paint colors and brushes to decorate what they assemble. The Music Box Kit ends with a mechanism that plays.
All three are aimed at ages 7 to 9, and all three come with detailed step-by-step instructions and every supply needed. Building and then painting the result is deliberate: the assembly does the logic and motor-skill work, and the decorating is what makes a child want to keep it.
