More than 400 students from 53 Milwaukee public schools took part in the MPS STEM Fair at the Milwaukee County Zoo.
Eighth grader Soren Henkel of Fernwood Montessori made a project everyone wanted to see. He made "an LED matrix that makes a hologram of your hand using lasers."
MPS science curriculum specialist Rochelle Sandrin says the MPS STEM Fair is an opportunity for students from all over Milwaukee to put their best science, technology, engineering, and math skills on display.
"The students are proud of their work and they're feeling really confident about what they did," Sandrin said.
Ninth grader Samia Sheikh took on the water distillation process and was surprised at what she learned.
"The actual distillation process is usually done in labs with big machines and stuff. So I found a way to do it at home and once I did it at home I found out how easy it was to home make this," she said.
Three judges scored each project. One of those judges was math and physics tutor Shareef Jackson of Math Looks Good, LLC.
"I'm really looking for curiosity, passion, and to be able to explain how they got from the hypothesis to the results," said Jackson.
