My Students

We are a Title I, K-5 elementary school located in the heart of North Portland. We have an unique population of students from over 20 different countries. 100 percent of our students receive free or reduced-price lunch. We try and address as many needs as possible at our school, but often lack the funding to provide the technological resources we need.

Many of our English Language Learners come to our school with no prior education.

The challenge of learning English and building proficiency in content subjects is overwhelming for many of our students. A lack of prior schooling has many of our refugee students completing schoolwork several grade levels behind their peers.

My Project

We would like to teach our kids about STEM in a creative and engaging way. Our goal is to build rockets from recycled bottles by using 3D printed parts. We will launch them using water pressure created by a bicycle pump and used tire valves.

Your generous donation to our project will enable our kids to learn a new technological 3D printing skill by utilizing the scientific method.

As our students go through multiple iterations to create a working model, they will learn about the stages of design and development; about identifying the flaws in previous versions in order to improve their rocket accordingly.

We are asking for a LulzBot Mini 3D printer and filament to help create the fins and nose cones on our rockets. Students will learn how nose cones help their bottle rockets reduce air resistance and remain in the sky longer. Students will be asked to hypothesize what types of shapes help propel their rocket into the air further. As they create their own wings, they will be asked to use sentence frames to describe the shape and size of different fins.

With your help and these supplies, we can bring 3D printing outside of the classroom and inspire our students to launch a new interest in science.
