The Long Beach Unified School District (LBUSD) Science Fair was held Saturday May 21, 2011 at Cabrillo High School located at 2001 Santa Fe Avenue in West Long Beach near Admiral Kidd Park.

LBUSD students have been anticipating this event since conducting their projects and submitting them almost two months ago.  A total of 1,100 students (the number of registrants) represented 56 LBUSD schools, including 34 elementary schools, 10 K-8 schools, 10 middle schools, and 2 high schools. 

A total of 125 reviewers, including Boeing employees, LBUSD teachers, CSULB professors and students, and community volunteers, volunteered their Saturday morning to support and inspire our future generation of scientists and science-literate citizens. Each student presenter had the opportunity to speak with at least two reviewers.

In addition to the student posters, there were numerous interactive exhibits including an 80 pound cobra to pet, solar boats, wind energy devices, and robots made by student engineers.

Eric Brundin, the School District’s K-12 Science Curriculum Leader, said of the Science Fair

“It is a testament to our great schools and families that in spite of all the economic and employment challenges people face, our district Science Fair has stayed strong. We are still huge, one of the largest such events in the nation, and the excitement of our students is as strong as ever. That, after all, is what keeps us going.”

At least one of the projects was relevant to urban agriculture. Maya, a 4th grader from Minnie Gant Elementary, raises chickens at home and told all about her experiments to test the differences between store bought eggs and fresh home grown eggs. Onlookers were impressed with her knowledge of chickens and the obvious differences in egg shell integrity that could be seen as she “candled” eggs with a bright LED flashlight. Excerpts from her poster presentation and report are given in the slideshow.

Maya said of the experience

“I really liked doing a science fair project. I think I was actually lucky to be picked to go to the fair. It was cool doing it on eggs.””

Next year, maybe you too will decide to do a science fair project based on something to do with agriculture.

“Most hens are usually raised in crowded not very nice factories in small cages. Only some ever see the sun or go outside. These are called pastured. My hens are pastured and they have names and I love them.”
