Curiosity Labs is a series sponsored by MilliporeSigma Corporation that connects their scientists with Mead Public Library patrons. Attendees will be treated to themed science presentations and will participate in hands-on group experiments.

Attendance is limited; preregistration required.

March 23: Chemiluminescence

This activity introduces students to the role of electrons in a chemical reaction and addresses energy transformation and the difference in energy between reactants and products. The investigation shows students how chemical reactions can emit light and allows them to investigate the effect of temperature on the reaction. Chemiluminscence has many practical applications, including glow sticks and forensic analysis.

April 27: Water Filtration

In this activity, students learn that of all of the water on Earth, only a very small percentage is potable, or safe for drinking. Students use this information as motivation to design a water filter using the engineering design process. After creating a prototype of their design, students test their filter by pouring dirty water through it. The process of filtration is tied to the physical properties of matter, and students learn how water filtration is used in the industry by scientists and individuals. Finally, students test their clean water by recording visual observations and testing the chlorine content of the water.

May 25: Flavors and Fragrances

In this lesson, students learn that humans can recognize more than 10 thousand scents. Students practice recognizing scents by smelling different chemicals on scent sticks. They then learn how their body recognizes and interprets scents. The focus is on how the structure of the chemical is what causes the unique flavor or fragrance of the chemical based on how it interacts with human sensory receptors. They then use their initial research on the different scents to design a unique fragrance for a particular purpose. Students present their fragrance to the class, including the name of their fragrance, how they created it, what product it would be used in, who their audience is and how much the product would cost.

MilliporeSigma is a global life science and high technology company that has a local branch in Sheboygan Falls. With the belief that corporations have a responsibility to be good citizens in their communities, we have strong commitments in the areas of scientific research and economic development through science and STEM education. While we support many STEM programs and organizations around the world, we have also created our own program called Curiosity Labs.
