Grab a play mat, blocks, and your favorite baby engineer. It’s time to build something—and see science at work!

Oh, my. You’ve gathered lots of materials.

What will you build?

With blocks at the ready, watch as your baby uses their hands to bear weight and the couch for support while experimenting with setting up a sturdy base, stacking a tower, spanning a space with an arch—and applying force, of course. Bash! Smash! Crash! Babies and toddlers are naturally curious explorers—now help them discover that science is fun! In this bright, graphic board book, photos of busy little ones offset a lively running dialogue sprinkled with factual asides that define basic engineering terms.
