January 17th marks the passing of two people, William Pickering and Clyde Tombaugh, who were important to the discovery of the dwarf planet, Pluto. William Pickering was an American astronomer who believed there was a planet outside the orbit of Neptune that caused the unusual shape of the orbit of Neptune and Uranus. He was instrumental in the establishment of Lowell observatory in Flagstaff, Arizona with Percival Lowell to search for this "Planet X". Powell spent the rest of his life searching, even photographing Pluto on film twice without recognizing the planet. Clyde Tombaugh joined the staff at Lowell Observatory and was given the task of taking systematic photographs of portions of the night sky on two nights one week apart. He would load the images in a device called a blink comparator that rapidly switches the two photographs.

Investigadores rusos han logrado sintetizar el elemento 118 de la tabla periódica. El docente puede aprovechar este avance científico para trabajar en el aula los elementos químicos y su posición en la tabla periódica. Para ello puede utilizar alguna de las cinco aplicaciones en línea recomendadas: juegos interactivos, vídeos sobre los elementos químicos, tablas periódicas dinámicas, apuntes y actividades online y una calculadora científica para la clase de Química. FUENTE: RIA Novosti Para comenzar la actividad, se puede sondear los conocimientos previos de química que poseen los alumnos mediante una pequeña reflexión en voz alta sobre el título de la noticia.

AP Chemistry Review Activities AP Chemistry Interactive Review Activities In keeping with the new framework for AP Chemistry beginning in 2013 - 2014, I am indicating here if the topic to which a review activity relates has been dropped from the curriculum. It will be identified as excluded (Excluded) to indicate that the College Board has specifically excluded it. I will leave the reviews here, however, in case some of you find them useful.
