Ms. Polmisano's supplies project at Armistead Gardens Elementary School in Baltimore is one Eli gave to.

*My Students: "Tell me, I'll forget. Show me, I'll remember. Involve me, I'll understand." This quote sums up our approach to learning in our STEM Resource Classroom. Throughout the year, students of all ages actively engage in engineering design challenges that aim to solve real world problems.*

*Our students are smart, curious, thoughtful, and respectful. They love learning and are always eager to try something new! They value what they have, which isn't always much. Our school is a Title I school located in Baltimore City. As a large urban school district, resources are spread quite thin. We are a PreK-8th grade school located in East Baltimore. Over 600 students attend our school and represent multiple nationalities.*

*Our students are curious, creative, and cooperative learners! They look forward to our projects with excitement and anticipation. Our classroom is a highly active and engaging learning environment. Students are always on the go as they’re guided through the Engineering Design Process. By brainstorming, planning, creating, testing, and improving products and prototypes, students are learning and applying science and math concepts, while exploring a variety of fields of engineering.*

*My Project: Students will engage in two new engineering challenges where they will explore materials and their properties in order to build devices. We will begin with simple machines, where students will research catapults, and explore the function of levers. We will test a variety of materials while designing a simple catapult system. Student teams will then be provided with a variety of materials to design their own unique catapult system, and compete in a catapult showdown to determine which models succeeded with both distance and accuracy.*

*We will then move on to our hydraulics and pneumatics unit, where we will explore the mechanical properties of liquids and gases. Students will participate in a variety of demonstrations and hands on activities to better learn how air and liquid can be used to design and improve mechanical systems. They will then develop their own pneumatic or hydraulic system that can be used to accomplish a common task.*

*In order to construct these designs and complete these investigations, my students require various building materials including syringes, pneumatics and hydraulics kits, catapult kits, a bottle launcher, paint stirrers, glue guns and glue, and rubber bands.*

*Today's students are the future scientists and engineers of tomorrow. It's important for educators to help students learn the skills and knowledge needed to be successful in these fields. Engineering challenges allow students to explore science concepts, apply math skills, and become familiar with STEM careers. These hands on activities engage all learners, and help students realize their valuable role on a work team. Students walk away not only knowledgeable, but also inspired and empowered!*
