If you have a trait, then usually at least one of your parents will, too. Review traits we are looking for, how to decide if you have the trait and how to document it on the hand-out. Let students complete the activities on the hand-out. Share findings with the group. Have the students take the hand-out home so they can see and document their parents' traits.
Evaluation Let each student share which traits they have and which traits their parents have.
Listen for evidence that they understand the concepts of genetics and the inheritability of traits. Extension Ideas Ask students to expand their charts of inherited traits. Brainstorm traits they could research, such as color-blindness, bloodtype, hair color, etc. After research and documentation students can share their findings either orally or in a written report. Have students make thumb- and footprints.
