Rye Neck High School students in Joseph Perlman’s ninth-grade accelerated geometry classes, who have been studying about the properties of trapezoids and exploring how to create projections using different angles, recently designed and successfully created holograms.

For their projects, the students used transparency paper, which they cut into four trapezoid pieces and taped together, to create a holographic projector before placing it directly on top of an iPad. As a result, the virtual image on the device was projected into their classroom.

“The purpose was to give the students a practical application of the topic,” Perlman said. “They were able to understand how these shapes are crucial to everyday technologies and why certain sizes work better than others.”

As a conclusion to their studies, the students were challenged to build a holographic projector that would create a bigger, clearer image and replicate it onto a larger scale.
