Clark Creek Elementary School STEM Academy students recently collaborated with Etowah High School Architecture & Engineering Design students on a design project. The elementary school students designed a 3-D toy to test calculating the area, perimeter and liquid volume of irregular shapes, as well as to test partitioning a shape into equal parts and expressing those parts as fractions. The high school students assisted with project design and construction. The elementary students also were responsible for creating names, packaging, instructions and commercials; then presenting the projects to the Etowah High School students Shark Tank for investment consideration.
