Science Now!

Last Thursday the Chen and Meyer labs set up booths at Wayne Central Middle School for the Science Now Expo. The night was a chance for students of the middle school and their parents to talk to members of the local STEM community and see some of the demonstrations. The booths included a guessing game of genetic inheritance, 3D printing, and a box of live bumblebees!

Halloween for the Department

Last week many people in the department got involved in some holiday festivities. Whether it was handing out candy in Hutchinson Hall for the Society of Undergraduate Biology Student’s trick-or-treating, carving pumpkins, or just getting dressed up in costume, we had a spooky time!
