Biology, physics, and art-this twirling DNA mobile will add energy to any classroom! Students will be mesmerized as the initial random motion of the mobile is transformed into a rhythmic wave as the motor twirls the brightly colored beads. If a bead ...

Accurate in every detail, this DNA model will be a tremendous assistance in helping your students visualize the structure of the double helix! The bond angles are precise, the sugars are pentagonal, and the phosphates are pyramidal-the result is a mo...

This three foot long strand of DNA demonstrates the twisted ladder-like arrangement of DNA. The ease of twisting and untwisting this large molecule will help students visualize the 3-dimensional structure of DNA. The brightly colored base pairs and t...

How do chromosomes duplicate when cells divide? What directs protein formation? Your students will develop hands-on familiarity with the structure and function of the DNA molecule as they construct and interpret models of DNA segments. Reproducible w...

Easy-to-assemble system for constructing DNA and RNA models and simulating replication and transcription. Build a DNA molecule and twist it into a double helix with 10 base pairs per helical turn-the same number as real DNA. Then “unzip” the model to...

Interactive magnetic model kit helps students visualize key interactions among DNA, RNA, and proteins! Students build detailed content knowledge of replication, transcription, and protein synthesis as they build the model and manipulate the pieces to...

Once your students have assembled their own model of DNA they'll have a much clearer picture of how it looks and works. The assembled models are flexible enough to twist into the double helix structure and can be “unzipped”-allowing the students to s...

A fascinating discovery-oriented approach to learning about the structure and function of DNA. Students embark on a sequential problem-solving exploration using clues, hints, and the model pieces themselves. By manipulating the pieces and seeing whic...

Dive deep into the atomic structure of DNA! Build models of each of the nucleotide bases—adenine, cytosine, guanine, thymine—and then pair them up. Model allows students to actually see the molecular and geometric structures of DNA and the hydrogen b...
