Women in STEM Collaboration

Science research students from P.J. Gelinas Junior High School pushed into classes at Setauket Elementary School to collaborate on STEM activities. The seventh and eighth graders used the Storyboard platform to write children’s books about influential women in science, technology, engineering and math. They shared their books with the elementary students, then conducted hands-on activities relating to the accomplishments of the women they wrote about.

The women scientists students learned about included Katherine Johnson, Dorothy Hodgkin, Chien Shiung Wu, Marie Curie, Rosalind Franklin, Mary Anning and Mae Jemison. Some of the related activities they participated in were constructing paper rockets, building 3D candy DNA models, completing an invisible ink lab and making glow-in-the-dark slime.

Not only were the elementary students eager to collaborate with those from the junior high school, the activities were also a culmination to Women’s History Month.

Three Village resident Ms. Erika Glus visited P.J. Gelinas Junior High School to share her remarkable story of escape and survival during World War II with Ms. Gobetz’s eighth grade English classes. Ms. Glus baked a loaf of bread to share with students. As bread meant so much to her family during years of scarcity, it became a symbol of love and a way to express gratitude while spreading a sense of community and connection. This visit was part of Ms. Gobetz’ Holocaust book club unit.
