Example Questions
Example Question #21 : Physical Science
Sam put a whole watermelon in a box. She described it to her sister using observable properties, and her sister had to guess what it is. Which set of properties matches the watermelon?
Square, green, hard, rough
Round, green, soft, rough
Round, green, hard, and smooth
Round, blue, hard, and smooth
Round, green, hard, and smooth
An observable property is something that describes an item or material and is gathered using the five senses. A whole watermelon is round, green, hard, and smooth. Someone could touch and see an entire watermelon and find all of these properties are true.
Example Question #22 : Physical Science
Brittany has a game to play with her friends. She will describe a material or object by its observable properties, and they have to guess what she is thinking of.
"The object I am thinking of is round, smooth, hard, and reddish in color." Which object is she thinking about?
The object that Brittany is thinking about has to be round, reddish in color, hard, and smooth. The yarn is soft, the baseball is white, and the mushroom is rough with a bottom that is not round, so none of these items meet ALL of the properties. The floating ball is red, hard, smooth, and round, so it meets all of the characteristics listed. Observable properties are a way to describe an item or material and gather information about the world around you.
Example Question #1 : Describe Materials By Observable Properties
Angie has a game to play with her friends. She will describe a material or object by its observable properties, and they have to guess what she is thinking of.
"The object I am thinking of is round, smooth, soft, and green." Which object is she thinking about?
Angie is using observable properties to describe an object. Observable properties are characteristics describing an item or material gathered with our five senses. The only item that completely meets all of the same features is the peas. The egg is hard, the green beans are not round, and the chickpeas are tan.
Example Question #23 : Physical Science
The properties of materials include features such as color, size, and shape, whether they are rough or smooth, shiny or dull, hard or soft, and flexible or stiff.
False
True
True
This is a true statement. Properties of materials can be determined by using the five senses. Once the features of an item have been identified, the items can be described, classified, or sorted by this information.
Example Question #1 : Describe Materials By Observable Properties
What does the term properties mean in science context? Example: I can describe materials by their properties. A rock is hard, grey, smooth, not bouncy, and is not flexible.
Items that are owned
Characteristics or features
Places where people live
To do things correctly
Characteristics or features
Properties are characteristics or features used to describe an item, object, or material. There are measurable and observable properties for all objects. Measurable properties are things like mass, weight, height, and volume. A tool must be used to find a measurable property. An observable property is found by using the five senses.
Example Question #2 : Describe Materials By Observable Properties
Bella put a dirty sock in a box. She described it to her sister using observable properties, and her sister had to guess what it is. Which set of features matches the sock?
Square, hard, green, and bouncy
Irregular shape, soft, white, and smelly
Irregular shape, hard, rough, and smelled fruity
Round, red, hard, and smooth
Irregular shape, soft, white, and smelly
An observable property is something that describes an item or material and is gathered using the five senses. A dirty sock is an irregular shape, soft, white, and smelly. Someone could touch, smell, and see a dirty sock and find all of these properties are true.
Example Question #1 : Describe Materials By Observable Properties
Jorah has a game to play with his friends. He will describe a material or object by its observable properties, and they have to guess what he is thinking of.
"The object I am thinking of is rectangular, bumpy, hard, and green in color." Which object is he thinking about?
The object that Jorah is most likely describing is the building block. It is green, bumpy on top, hard, and a rectangular shape. These observable properties can be used to describe the item in detail. Observable properties are determined with the five senses.
Example Question #21 : Classification Of Materials
Daria got a new kitten. She was on the phone with her grandmother and wanted to describe it using his observable properties. Which list best matches the description of the kitten?
Tan, brown, hard, bouncy, and cold
Tan, brown, soft, not bouncy, squishy, and warm
Tan, brown, soft, bouncy, squishy, and cold
Brown, soft, orange, warm, not bouncy, and magnetic
Tan, brown, soft, not bouncy, squishy, and warm
Daria can describe her kitten using observable properties. Observable properties are characteristics of an item, person, material, or even animal that are collected using the five senses. This kitten is tan, brown, soft, not bouncy, squishy, and warm. Using the senses of touch and sight, these features can be determined.
Example Question #1 : Describe Materials By Observable Properties
Zara has a game to play with her friends. She will describe a material or object by its observable properties, and they have to guess what she is thinking of.
"The object I am thinking of is long, curved, smooth, soft, and green." Which object is she thinking about?
Angie is using observable properties to describe an object. Observable properties are characteristics describing an item or material gathered with our five senses. The only thing that completely meets all of the same features is the green beans. The egg is hard, the peas are round, and the chickpeas are tan.
Example Question #1 : Describe Materials By Observable Properties
Measurable properties are an item's color, size, and shape, whether they are rough or smooth, shiny or dull, hard or soft, and flexible or stiff.
True
False
False
This is a false statement. The observable properties of materials can be determined by using the five senses. Once the features of an item have been identified, the items can be described, classified, or sorted by this information. Measurable properties require a tool and a measurement to be taken place. Examples of these types of features would be height, weight, volume, mass, etc..
