3~6세 어린이를 위한 거대한 과학 활동 백과사전 - 페이퍼백

My 4-year-old asks to do the sink-or-float page almost every afternoon now, and the setup takes about two minutes with stuff we already have in the kitchen. What sold me is that every activity is teacher-tested and aimed squarely at the 3-to-6 range, so I'm not filtering out stuff that's way over he

The sheer number of activities in here is what sold me—over 600, so I'm not scrambling for ideas on a rainy Tuesday. My four-year-old spent a solid hour on the sink-or-float experiment, and the instructions are simple enough that I barely had to prep.

The activities are genuinely teacher-created and it shows: the bubble experiment kept my 4-year-old busy for almost an hour with stuff we already had in the kitchen. My only gripe is that some activities skew toward the older end of the 3 to 6 range, so my toddler mostly watches her brother.
