Kelly is trying to decide which item number is most likely describing the seashell below based on its observable properties. Looking at the data table, which item is the best match?
Kelly is trying to decide which item number is most likely describing the seashell below based on its observable properties. Looking at the data table, which item is the best match?
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.

Ralph made a table with the descriptions of four mystery items, and his friend Steven had to guess which item was describing a teddy bear's observable property. Which item should Steven choose as the teddy bear's description?
Ralph made a table with the descriptions of four mystery items, and his friend Steven had to guess which item was describing a teddy bear's observable property. Which item should Steven choose as the teddy bear's description?
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.

Which answer choice could be classified as "Item 2"?
Which answer choice could be classified as "Item 2"?
"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 classify all of the items listed. What observable property are all of the items in "Category 3" sorted by?
Observable properties classify all of the items listed. What observable property are all of the items in "Category 3" sorted by?
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 classify all of the items listed. Which category would Rishi put a green gummy bear in based on its properties?
A green gummy bear would not fit into any of the categories based on its observable physical characteristics. "Category 1" is all rectangular or square objects, "Category 2" are round items, and "Category 3" is all brown items. A green gummy bear would need to be placed in a new category.

Which answer choice could be classified as "Item 4"?
When looking at items or materials, we can classify them based on their observable properties. If we look at the different descriptions of all four items and then think about a tennis ball, some similarities can be found between item 4 and a tennis ball. They can be described with the same properties, so they fall into the same category.

When looking at items or materials, we can classify them based on their observable properties. If we look at the different descriptions of all three items and then think about a baseball, some similarities can be found between item 2 and a baseball. They can be described with the same properties, so they fall into the same category.

Observable properties classify all of the items listed. Which category would Montel put a notebook in based on its features?
Observable properties classify all of the items listed. Which category would Montel put a notebook in based on its features?
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 things are brown, so they are classified by color. In "Category 2," all of the items are round, so they are sorted by shape. In "Category 1," all of the things are square or rectangular, so they are also categorized by shapes. The category that a notebook would best fit in is "Category 1".

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.

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.

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.
