L Is For Lyceum - Fluorescent Minerals (December 22 2016 – December 31 2017) In the ancient world, the lyceum was where the greatest Greek philosophers taught. The concept of the lyceum was revived by American intellectuals in the 19th century who believed that public education was an important part of our democracy. Founded in 1854, the Grand Rapids Public Museum was originally named the Grand Rapids Lyceum of Natural History. In 2015 the Grand Rapids Public Museum School was founded with many community partners. The Museum School has developed its own version of the lyceum - an innovative after-school program that pairs local experts with middle school learners to exercise their minds and bodies by exploring an eclectic range of topics.
This changing exhibit was created by a class of lyceum students who designed the exhibit from start to finish, choosing the topic, selecting the artifacts and writing the text.
L is for Lyceum is one section of the interactive exhibit Collecting A to Z. This exhibit includes thousands of treasures from the GRPM’s Collections featured throughout the Museum.
