The data table that matches the ping pong ball and basketball need to have observable properties that would describe those objects. Observable properties can be found by using your five senses. A ping pong ball is white, small, round, bouncy, hard, strong, and smooth. A basketball is orange, round, bouncy, hard, strong, and rough.

This is a true statement. We can use our five senses to observe things like the color, texture, taste, smell, and hardness of objects. This information allows us to describe objects, classify them, and categorize them.

This is a false statement. The properties listed in the question do help scientists understand materials, and those characteristics describe them well, but they are not observable. Observable properties are things we can use our five senses to determine, the measurable properties in the question need a tool like a thermometer or a ruler to determine.

The flower that Diana likely found in her backyard is a lilac. The flower she describes using observable properties matches the image of the flower. They are both purple and green, soft, smooth, and would not bounce. Observable properties can be identified using our five senses and what Diana described appears to be lilacs.

The item that is most likely describing the seashell is "Item 1". A seashell has all of the matching observable properties, so it could be classified in the same category. A seashell is hard, does not bounce, is irregularly shaped, tan, and would feel rough to the touch. None of the other items would be a match.

Steven should guess "Item 4" is a match to his teddy bear because they share the same observable properties. The teddy bear is brown, soft, smooth, would not bounce, and is an irregular shape. The other items could not be classified as a teddy bear.

"Item 2" is described as hard, not bouncy, square, green, and smooth to the touch. When reviewing the answer choices, they are all green but have other observable properties that would not allow them to be classified as "Item 2". The tennis ball is round, the block is rough on top and rectangular, and the leaves are irregular shaped. The only answer choice that matches the characteristics is the cube.

Observable properties are characteristics of an object or material that can be gathered using the five senses. When looking through each category, there is a common property that groups the items. In "Category 3," all of the items are brown, so they are classified by color.

Observable properties are characteristics of an object or material that can be gathered using the five senses. When looking through each category, there is a common property that groups the items. In "Category 1," all of the items are rectangular, so they are classified by shape.
