Step by step, your students can build a DNA molecule model, and simulate the 'unzipping' of hydrogen bonds in the replication of DNA.

• Materials for 10 setups
• Easily expanded with a student pack
• Estimated class/lab time required: 45 Minutes
• Aligned to NGSS standards (MS/HS: LS1, LS3)

Individual models snap together to form chains and ladders, and can be linked with other models. The double chains also 'unzip' for a vivid demonstration of DNA replication.

Includes a teacher's guide with instructions and reproducible student worksheets. The kit is also available for purchase with a link to NewPath digital resources, which include a lesson with background information, illustrations, and self-assessments.
