Answer Key

Attributes of an object

Section A: Quick Questions

A — Colour: brown

B — Screen size: 6.1 inches

A — Each attribute holds one fact

B — Three attributes: colour, gears, wheel size

A — Number of gears

Section B: Match the Pairs

Pet: name, colour, age → Lists three attributes that describe a pet

Phone: brand, model, storage → Lists three attributes that describe a phone

Each attribute holds only one fact, so a bike's colour and size are kept as two separate attributes → Bike: colour = Red, size = 26

Choose only the attributes that matter for the job, such as a pet's name and age for a vet check-in list → Pet: name, age

Bike: colour and size = Red 26 → Two facts are squashed into one attribute. Colour and size should be separate attributes, each with one value.

Pet: name = Max, Buddy, Rex → One attribute holds several values. The pet's name should be a single fact, and the other names do not describe the same pet.

Section C: Definitions

attribute — One fact that describes an object, such as a pet's name, colour or age. Each attribute holds a single piece of information.

Section D: Fill in the Blanks

Object: Pet
Attribute: name = "Milo"
Attribute: colour = "grey"

Object: Bike
Attribute: colour = "red"
Attribute: wheels = 2

Object: Bike
Attribute: colour = "red"
Attribute: wheels = 2

Object: Pet
Attribute: name = "Milo"
Attribute: colour = "grey"

Object: Phone
Attribute: brand = "Samsung"
Attribute: storage = 128

Section E: Spot the Error

D — An attribute holds only one fact. 'age: 4 and likes fish' mixes two facts. It should be 'age: 4', with the food as its own attribute.

D — A phone does not have wheels, so this attribute does not describe the object. It should be a phone attribute such as 'storage: 128 GB'.

C — Each attribute is one fact on its own line. This line packs two attributes (colour and size) together. It should be 'colour: red'.

C — The value must match the attribute. 'brown' is a colour, not an age. It should be a number such as 'age: 3'.

C — Choose attributes that matter for the goal. A bike buyer does not need the owner's lunch. It should be a useful attribute such as 'price: $450'.
