El gran libro de proyectos de Ada Twist para científicos estelares

My nephew asks "why" about everything, so this activity book with its step-by-step experiments is perfect for him—the page where you design your own volcano was a huge hit. We've already done three projects and he's begging for more.

My daughter and I dove into the hands-on activities first, and the step-by-step instructions for building a simple catapult were clear enough for her to follow on her own. It’s sparked a whole new curiosity about how things work, which is exactly what we needed.

My son loved following the simple experiment steps and asking his own "why" questions right along with Ada. The sturdy paperback pages have held up well through multiple readings, too.
