Subject: Science, Mathematics

Grade level: Grades 7-12

Activity type: Web Survey

Activity level: Beginner

Timeframe: 10 weeks

Partners: Unlimited

Objectives

• Students research dominent and recessive gene traits.
• Students analyze, interpret, and report on data.

Prerequisites

Materials Needed

• One computer with email/Web access;
• Database or spreadsheet software (optional)

Procedure

For Older Students

1. Have students research dominent and recessive gene traits and create a survey to test the traits on a large sample. Include questions about at least 3 dominent and 3 recessive genes in your survey.
2. Conduct an email survey of other students across the U.S. by posting the survey for other classrooms (offer to share all data with respondees).
3. Once the results are in, help students design a database (either manually or online using spreadsheet software) and compile data.
4. Have students analyze data.
5. Present data in class using graphs, bar charts, and pie charts.

For Younger Students

• Elementary students can modify this activity by surveying students on a fun genetic trait such as the ability to curl your tongue.
