Head Start on Engineering

Head Start on Engineering is a bilingual, family-centered program designed to engage preschool children and their parents and caregivers in the engineering process. The program focuses on the engineering design process, rather than the field of engineering, as a topic and skill that is highly relevant to the everyday lives of families, helps make engineering feel approachable, and easily connects to early childhood play and learning practices.




The Head Start on Engineering project has recently introduced a new type of resource for families and teachers: Sparks!. These bilingual (Spanish and English) activity ideas are a fun and easy way for families to learn together at home that support preschool-age children’s development and spark family engagement with engineering design.

MPACT Objects (1)


MPACT provides opportunities for students in grades 4 through 7 to engage in computational thinking, spatial reasoning, and mathematical concepts through design and hands-on making projects. MPACT addresses key topics in most state standards for math and national standards for computer science. Students learn concepts and solve problems with real objects they can hold in their hands, not just with words and diagrams on paper. Available for use and adaptation for non-commercial purposes, with a Creative Commons license. 




In BioRobots middle school students: study the natural world to learn how animals accomplish different tasks, then design and build a robot inspired by what they learned; learn how to build and program a robot; and practice computational thinking, scientific reasoning, and engineering design skills. There is a One Hour Activity, Curriculum, and supporting resources.
