What are the observable properties that we can use to describe materials?
What are the observable properties that we can use to describe materials?
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.

What does the word observable mean?
What does the word observable mean?
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.

Cheryl has a ping pong ball and a basketball and wants to investigate their observable properties. Which data table matches the properties of the two objects?
Cheryl has a ping pong ball and a basketball and wants to investigate their observable properties. Which data table matches the properties of the two objects?
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.

Which object matches the list of observable properties below?
Which object matches the list of observable properties below?
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.

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.

I can investigate materials and use observable properties to describe, classify, and categorize them.
I can investigate materials and use observable properties to describe, classify, and categorize them.
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.

Observable properties include measurements like height, weight, temperature, and the volume of an object.
Observable properties include measurements like height, weight, temperature, and the volume of an object.
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.

Diana found a flower in her backyard and wants to investigate what it is. What flower is Diana describing with the observable properties data table below?
Diana found a flower in her backyard and wants to investigate what it is. What flower is Diana describing with the observable properties data table below?
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.
