    What Happened to Pluto?

    What Happened to Pluto?


    This resource is a Science student activity that utilizes Utah's Online Library resources - specifically, EBSCO's Science Reference Center to help students learn about planets and the specifications that designate a heavenly body as a planet. 

    About Utah’s Online Library

    Utah's Online Library provides Utah educators and students free access to high-quality reference collections such as EBSCO, Gale Reference Collection, World Book, eMedia, and LearningExpress Library.

    This activity was designed to help educators utilize this amazing resource in their classrooms.

    Note: Utah educators and students visiting Utah's Online Library from a school computer should be automatically authenticated. When at home, students must use the home access login that their teacher or school media specialist can provide. Utah educators can use either their my.uen login or the home access login.


    Essential Question: How do scientists classify objects in outer space?

    Why did Pluto lose its designation as a planet? What new specifications do scientists now use to designate a heavenly body as a planet?  Students can use the resources in Utah's Online Library to research relationships and attributes of objects in the solar system. EBSCO’s Science Reference Center has in-depth information about the eight planets as well as information about asteroids, the sun, black holes, supernovas, comets, and space exploration.
