Baby animals and their parents are the focus of this two-part 3rd grade traits sheet. First, students match three babies to a bear, a cow, or a chicken from the word bank and name one shared trait, such as spots, brown fur, or feathers. Then they study a picture of three kittens and say how the kittens are alike and how they differ. The sheet defines trait and variation in plain words and supports NGSS 3-LS3-1.
3-LS3-1
“Analyze and interpret data to provide evidence that plants and animals have traits inherited from parents and that variation of these traits exists in a group of similar organisms.”
The parent matching task covers traits passed from parents, and the two kitten questions cover variation among siblings.
Students write the parent's name under each baby animal and list one trait they share. The key pairs the cow with spots, the bear with brown fur, and the chicken with feathers or a beak.
Question 1 asks for one trait all three kittens inherited. Question 2 asks for one variation that makes them look different.
Introducing traits
Use this on the first day of your heredity unit. The definition of a trait names fur color, beak shape, and eye color, so students have examples before they start.
Family photo link
After the kitten questions, invite students to bring a photo of a pet with its litter. They can find one shared trait and one variation, just like on the sheet.
English learners
The word bank has only three animals and the answers are one or two words. It lets newcomers show the science without long writing.
