Alike or Different?
This is the age when most children begin to notice and point out similarities between themselves and those around them. Of course, the most noticeable characteristics that represent differences are things like hair color and texture (e.g., yours is blonde, mine is curly), eye color, and skin color. Don’t discourage your child from noticing differences. In fact, ask her about the differences within her own family (“Who has blue eyes? You and Daddy, but not Mommy.”). These similarities and differences introduce your child to important big ideas in biology, too, such as heredity, diversity, and variation.
