My Students

My 3rd grade students come to school eager and excited to learn. A typical day in my classroom includes hands-on learning experiences and full student engagement utilizing STEAM projects.

I work at a Title I school with minority students that come from low socioeconomic backgrounds--and many of them enter my class below grade level in mathematics and reading.

As their teacher, I understand the need to prepare my students for the 21st century by embedding 21st Century Skills and real-world opportunities to help students succeed in all academic areas.

My Project

This project is the second phase of Lend a Helping Hand with 3D Printing. During the first phase, students learned that designs could be created three-dimensionally using various apps and websites. Students had to think critically and creatively when developing their designs--which were printed using our 3D printer. Students were intrigued by the fact they could create something digitally and bring it to life with 3D printing.

For this phase of our project, the filament and materials kits will be used to teach my students the design and engineering process of developing and assembling prosthetic hands for the purpose of helping children who do not have two functioning hands.

Students will work in groups to select and engineer various prosthetic hand designs, and will download and print the files using our 3D printer and filament. Each group will work together to use the materials kits to assemble their prosthetic hands and will test their hands to determine whether their design can complete basic tasks--i.e. holding a pencil, holding a cup of water, catching a ball. Students will also document this process through digital journaling that will be shared with classmates, parents, teachers, and administrators.

3D printing has already opened a world of engaging opportunities for our class. We are excited to build upon what we have already learned in the first phase of this project to produce a final product that could potentially change the life of a child!
