OVERVIEW: The study of genetics/inherited traits is more than simply tracing back or predicting eye and hair color. Our genetic code is specific from one person to another. We do pass on other, more unusual traits, such as the ability to discern specific tastes in foods.
This activity was designed to involve students, family members, and selected peers in the process of determining whether an individual can be classified as a taster or a non-taster.
OBJECTIVES: The student will be able to:
RESOURCES/MATERIALS: Teacher materials:
ACTIVITIES AND PROCEDURES:
TYING IT ALL TOGETHER:
Students will share their experiences with their families and friends. Students can place tally marks on yesterday’s chart. Discuss whether their predictions were correct. Analyze findings.
Follow up activities could include the construction of a Punnett Square using the information collected from parents. The percentage of offspring that are tasters could be predicted, and more testing done to check.
Some may hypothesize that people who tend to be overweight are tasters, or that thinner people are non-tasters. Is this how obesity seems to run in families???? An experiment could be designed and carried out to prove the hypothesis.
This is a great activity to get family members involved in Science. It can snowball into a very large data gathering activity. The MacIntosh has a great program, Excel, that is very helpful organizing and graphing this kind of data.
These lesson plans are the result of the work of the teachers who have attended the Columbia Education Center’s Summer Workshop. CEC is a consortium of teacher from 14 western states dedicated to improving the quality of education in the rural, western, United States, and particularly the quality of math and science Education. CEC uses Big Sky Telegraph as the hub of their telecommunications network that allows the participating teachers to stay in contact with their trainers and peers that they have met at the Workshops.
