The DNA Molecule Is Shaped like a Twisted Ladder
One of the first models of DNA appeared to be a triple helix. Young scientists learn about the many scientists who worked to find the shape of DNA. They observe multiple models, tests, and experiments to understand the conclusions. An...

The Race for the Double Helix
Students participate in an ethics-based simulation. In this ethics instructional activity, students role play research scientists working to decipher a code. Students work in small collaborative groups and must interact with other small...

Sci-Fi/Biotech Video Worksheets
Students watch two commercial films which portray an historical perspective and possible uses of biotechnology in order to better understand the vocabulary and techniques involved in genetic engineering.
Oregon State University
Oregon State University: Linus Pauling and the Race for Dna
A great resource for the history of the discovery of DNA! This website includes over 300 documents, photographs, audio clips, and video excerpts that documents how the double helix structure was discovered.
Khan Academy
Khan Academy: Crick, Watson, and Franklin
This article describes the race to unlock the mystery of life by determining the double helix structure of the DNA molecule. The discovery of DNA and its structure is an example of collective learning.
