Be a DNA detective
Background
Key Learning Question
What scientific techniques can we use to determine paternity?
Prior Knowledge
A knowledge of the meaning of the terms gametes, genes, alleles, genotypes and phenotypes would be preferable.
Learning Intentions
In this program students will:
- Learn how blood typing is determined.
- Understand the DNA structure and some inheritance mechanisms.
- Gain an understanding of how gel electrophoresis works.
Activities
Students will:
- Test for blood groups using antibodies and learn about co-dominance.
- Complete activities looking at the structure of DNA
- Load and run an electrophoresis gel.
Learn Online
Ecolinc Learn Online is a virtual outreach learning management system (LMS) offering interactive online courses for students and teachers. These courses can be undertaken either as a pre-visit, post-visit or stand-alone.
Students are encouraged to do the course on Ecolinc Learn Online called Cold Case 1: The Romanovs as either a pre or post visit to Ecolinc. Students will assume the role of a forensic investigator to solve mysterious aspects of Russia’s historical Romanov tragedy. In the process of analysing the evidence and forensic reports, students will learn valuable lessons about forensic scientific methods and practice.
Victorian Curriculum
Science: Level 9-10
- Advances in scientific understanding often rely on developments in technology and technological advances are often linked to scientific discoveries (VCSSU115)
- The transmission of heritable characteristics from one generation to the next involves DNA and genes (VCSSU119)
- Select and use appropriate equipment and technologies to systematically collect and record accurate and reliable data, and use repeat trials to improve accuracy, precision and reliability (VCSIS136)
- Analyse patterns and trends in data, including describing relationships between variables, identifying inconsistencies in data and sources of uncertainty, and drawing conclusions that are consistent with evidence (VCSIS138).
