1. Answer the following question on the blank purple sheet using complete sentences, appropriate
language, and include any necessary data or information to best answer the question.

and Sirius (a star).
2. (will be presented by slide about 5 minutes after question 1 is provided) What if the following
objects were added to your list? Expand your response to #1 with the added items:
Pluto, Mars, Vega, Comet Hale-Bopp
3. (will be presented about 5 minutes after question 2 is provided) Recategorize your list of objects so
that they are classified by composition of the object. Explain how this would affect your previous
categorization and classification of the objects.

2. Answer the following question on the blank purple sheet using complete sentences, appropriate
language, and include any necessary data or information to best answer the question.
1. Below are listed several objects – for each, list at least two properties about that object based on
what you know about it, and state what “category” each object might fit into based on these.
Objects: Earth, Venus, Saturn, the Sun, the Moon, Io (one of Jupiter’s satellites), Ceres (an asteroid),
and Sirius (a star).
Categories: Stars, Satellites of Stars, Satellites of Planets
2. (will be presented by slide about 5 minutes after question 1 is provided) What if the following
objects were added to your list? Expand your response to #1 with the added items:
Pluto, Mars, Vega, Comet Hale-Bopp
3. (will be presented about 5 minutes after question 2 is provided) Recategorize your list of objects so
that they are classified by size of the object. Explain how this would affect your previous
categorization and classification of the objects.

3. Answer the following question on the blank blue sheet using complete sentences, appropriate
language, and include any necessary data or information to best answer the question.
1. Using the list of objects below, generate at least two different categories of objects that these
could be divided into. Define each category, and explain why each of the objects would fit the
categories you just defined.
Objects: Earth, Venus, Saturn, the Sun, the Moon, Io (one of Jupiter’s satellites), Ceres (an asteroid),
and Sirius (a star).
2. (will be presented by slide about 5 minutes after question 1 is provided) What if the following
objects were added to your list? Expand your response to #1 with the added items:
Pluto, Mars, Vega, Comet Hale-Bopp
3. (will be presented about 5 minutes after question 2 is provided) Recategorize your list of objects so
that they are classified by location of the object. Explain how this would affect your previous
categorization and classification of the objects.

4. Answer the following question on the blank blue sheet using complete sentences, appropriate

From your descriptions, create at least two possible categories to classify these or other objects.
2. (will be presented by slide about 5 minutes after question 1 is provided) What if the following
objects were added to your list? Expand your response to #1 with the added items:
Pluto, Mars, Vega, Comet Hale-Bopp
3. (will be presented about 5 minutes after question 2 is provided) Recategorize your list of objects so
that they are classified by another set of properties (different from what you selected in problem 1).
Explain how this would affect your previous categorization and classification of the objects.
