Part of the fun at Summerbridge is having a guest speaker visit and give a fun presentation. Kathleen Theodorou of Air Products and Chemicals, Inc visited Summerbridge with her colleague David Kish to teach the students about Liquid Nitrogen. Of course the presentation included a demonstration that required audience participation!  Morgan Mattes and Keana Makari, 7^th graders at LVS, had a hands-on lesson about the effect of Liquid Nitrogen on flowers. The LIN Program at Air Products is part of the company’s community outreach program. Thanks to Ms. Theodorou and Mr. Kish for a fun and informative presentation!
