Observable properties are characteristics or things about materials or objects that we can describe using our five senses. Color, texture, hardness, and flexibility are all things we can determine with our senses.

The term observable means to be noticed or perceived. If something is noticeable, I can touch it, taste it, see it, hear it, or feel it. We can observe the properties of a material and use it to determine what it is or how to classify it.

Another term for materials is matter. Matter is what things are made of. All materials, objects, and living things are made of matter.

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.

The observable properties listed give us a clue to what the mystery object is. We know the object needs to be yellow, soft, smooth, and it should not bounce. An apple is typically not yellow, a ping pong ball IS bouncy, and basketballs are generally bouncy and orange, so they are not a match. That leaves a banana which meets all the observable properties.

The object that Janice is describing is a die or pair of dice. They are bouncy, hard, smooth, and black and white. The other choices are black and white but don't meet the other observable properties.

Observable properties are characteristics of an object, person, or material. We use our five senses to make these observations. From the pictures, we can see what the two flowers look like and use this information to help match the correct data table.

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.
