Milwaukee Public Schools to host 14th annual student STEM Fair


This week, nearly 140 projects by MPS students from 16 schools will be presented virtually during MPS STEM Fair. Young scientists will showcase their research, experiments, and inventions to a panel of judges during the14th annual event.

Student work ranges from practical inventions to solve everyday problems to experiments designed around scientific principles. Projects are divided into three categories: Science Inquiry (traditional), Engineering Design (solving a problem), and Research Study (high school only, for complex projects).

At Gaenslen School, projects lasted more than two months for research, experimentation, and conclusions. Students learned to apply the scientific method—observation/question, research, hypothesis, test, analysis, and conclusion—to questions and problems they identified and wanted to learn more about.

Special education students in grades 4 and 5 learned about solids, liquids, and gases by predicting and then testing which liquids would dissolve suckers fastest. Students tested hot water, cold water, and soda. After identifying variables and running their experiment three times, they discovered that hot water dissolved suckers fastest.

Kindergarten students learned about chemical reactions by mixing hydrogen peroxide, water, food coloring, and other substances to develop elephant toothpaste. They explored solids and liquids, learned to make predictions, and watched their ingredients blend and thicken into toothpaste.

Student Madison Robinson, a 7th grader, decided to experiment with physics by constructing an infinity mirror. Her mirror, consisting of two mirrors in a box with lights, gives the illusion of a never-ending tunnel. She experimented with construction techniques and the distance between mirrors to achieve different results including an infinite tunnel, a kaleidoscope, and an endless tunnel of lights.

These exciting projects are among a total of 16 entries that Gaenslen has entered in STEM Fair. Families, friends, and community members can tune in virtually and watch the young scientists’ presentations May 3 through 6 during four time slots: 9:00–9:45 A.M., 10:00–10:45 A.M., 11:00–11:45 A.M., and 1:00–1:45 P.M. (no afternoon session on May 6). Families who would like to know the exact time and room of their student’s presentation should contact their child’s teacher for information.
