- Science Process Skills
- Materials (per person)
- Doing the Activity
- Read through the list of traits (see below). When
you hear the "go-ahead", move around the room and
start checking out the other people in your
- Find someone else in your group who has one of
these traits. Ask each person to sign his/her name
next to the trait that he/she has. Try to get each
person to sign the sheet only once.

- What happened? Were you able to find people that
had the same traits? different traits?
- What traits do you possess?
- What was the most common trait?
- How could scientists apply common traits to plants
and animals? How are certain traits affected by
- What's Happening
- Every organism requires a set of instructions for
specifying its traits. Heredity is the passage of these
instructions from one generation to another. Heredity
information is contained in genes, located in the
chromosomes of each cell. Each gene carries a single unit
of information. An inherited trait of an individual can
be determined by one or by many genes, and a single gene
can influence more than one trait. A human cell contains
many thousands of different genes.
- More Challenges
- Do a survey of everyone in your neighborhood. What
are their common traits?
- Find out how identical twins are affected by
genes. What traits do they have in common.
- Make a family tree including traits. How common
are certain traits in your family?
