Ever find a leaf and wonder about the tree it came from? Leafsnap is a series of electronic field guides being developed by researchers from Columbia University, the University of Maryland, and the Smithsonian Institution. The free mobile apps use visual recognition software to help identify tree species from photographs of their leaves.

Kimberlee, a 6th grade student at Kanesville Elementary, had amazing achievements at this year’s science fairs. She won first place at the school science fair, and then won first place in Chemistry at the district science fair. She also won a Broadcom Master’s Award at the district fair. Kimberlee also attended the regional Ritchey Science and Engineering Fair, and won first place in Chemistry there as well! Her project was titled "Blood Glucose Challenge." She tested several people of different ages to see if age had an effect on how quickly sugar is metabolized. She did this by having people drink a sugar-filled soda, and then tested their blood sugar at regular intervals for the next hour. Kimberlee was even able to tell someone to go to the doctor, where they were diagnosed with diabetes, based on this project! She is amazing!
