Partners - September 23

Today students were working with partners in science. Together they read and learned that astronomers had reasons for classifying Pluto as a dwarf planet.  By reading a book called "What about Pluto?," students defended the claim: Pluto should be a planet.  They found and wrote evidence in the text that supported this claim. However, Pluto was still reclassified.  Astronomers, in 2006, decided on specific criteria to classify solar system objects as planets:

1. A planet must orbit the sun.
2. A planet must be large enough for gravity to give it the shape of a sphere.
3. A planet needs to be much bigger than any other object in its orbit and not part of a belt of similar objects.

Ask your child which 'rule' above changed Pluto's classification to a dwarf planet.
