With this bilingual (Spanish/English) educational app, preschool-age kids explore STEM concepts through play! They design and test roller coasters, use simple tools to problem-solve their way through an obstacle course, build clever contraptions to deliver food to hungry animals, and construct boxy towers to rescue a kitty from a tree. A parent section provides related real-world activities that encourage hands-on exploration and tips that help parents guide learning both inside and outside the app.
