Nine statements about an adult dog and a young puppy, labeled A to I, go into a two-circle Venn diagram on this 1st grade science page. Students write each letter in the Adult Dog circle, the Puppy circle, or the overlap. Three letters belong in each part: only the grown dog takes care of babies, only the puppy drinks mother's milk, and both have fur and a tail. The answer key lists all nine letters by circle, in line with NGSS 1-LS3-1.
1-LS3-1
“Make observations to construct an evidence-based account that young plants and animals are like, but not exactly like, their parents.”
The middle of the Venn (four legs, fur and a tail, needs food to live) shows how a puppy is like its parent. The two outer circles show how it is not exactly like it.
Nine lettered statements, from A (Has four legs) to I (Can have puppies), go into a Venn diagram of an adult dog and a young puppy.
C, F and I belong to the adult dog, B, E and H to the puppy, and A, D and G sit in the middle.
First Venn diagram
If the class is new to Venn diagrams, place statement A together on the board. Four legs goes in the middle, which shows what the overlap means.
Talk partners
Statement H, "Is just learning to walk," starts the best debates. Let pairs talk it through before they write the letter.
Stretch task
Have students write one new statement for each part of the diagram, such as a fact about how dogs and puppies sleep or play.
