The Hydraulics STEM Boost Kit is a hands-on fluid mechanics kit for one elementary student. Learners build and test animated hydraulic puppets while exploring how pressure creates movement, guided by bilingual student guides (English and Spanish). Students design a puppet, connect it to a syringe-and-tube hydraulic system, and then use it to tell a story—blending engineering with literacy. All supplies are included—no additional materials or technology required. Works in classrooms, makerspaces, afterschool programs, camps, and home learning environments.
