Help Kena's Students Shine at The ISEF National Science Fair

My name is Kena Allison and I am a teacher in Washington, DC. Three of my students won the DC science fair and are qualified to attend the national science fair in Columbus, OH. Due to recent constraints on the DC budget, the expenses of the fair have not been covered as planned. Now we are days away from the fair and I am covering the cost. The registration is $1400, hotels are $1800 and flights are likely to be another $1200. Additional expenses include food and taxis. Any help would be greatly appreciated!!
