Inherited traits family survey

Identify several inherited traits, features passed down from parents to offspring, such as eye color or attached earlobes, by collecting real family survey data.

A trait is any feature of a living thing, like eye color, height, or a plant's leaf shape. An inherited trait is one that is passed down from parents to their offspring, carried inside information in every living cell. You likely share several inherited traits with your parents or grandparents, such as eye color, hair texture, or whether your earlobes are attached to your head or hang free.

This week you become a real data collector: survey a few family members for several traits, and record what you find, just like a scientist gathering evidence.

📋 For the teacher
Teach it (10–15 min):
  • Actually run the survey together: check earlobes in a mirror, try rolling your tongue, compare eye color with a parent or a photo.
  • Ask a parent or grandparent, if available, what they remember about their own traits growing up for comparison.
  • Record results together in a simple written list, one column per trait.
  • Discuss any surprising matches or differences found in the family data.
Talk about it:
  • Which trait did you share with a parent or relative?
  • Which trait was different from a parent's?
  • Why might siblings with the same parents not look exactly alike?

Mastery looks like: They collect real family data on at least three inherited traits and correctly explain what makes a trait "inherited."

Common stumbles: Confusing an inherited trait with something chosen or learned, like a hairstyle or clothing preference, rather than something present from birth.
