Where's the CAT? a DNA Profiling Simulation.

Seventh-graders come in to science class to find a file on their desks detailing a crime to be solved! As a demonstration, you simulate the restriction of DNA samples and separate them by electrophoresis. From the gel, learners can...

Everyone loves a good mystery ... can your class actually solve one? Partnered pupils take on the role of forensic investigators during a three-part activity focusing on DNA evidence processing. Learners discover the methods used to...

Junior geneticists construct models of DNA to discover sequencing and pairing of nucleotides. They use the models to simulate protein synthesis and then translate the codes into physical traits. Finally, they use the traits to create a...

Police find a man murdered in a local hotel, DNA everywhere, and now they need scholars' help. Budding detectives step into a crime scene playing the roles of victim, suspects, and investigators. They apply knowledge of criminology and...

What is in that double helix? Explain intricate concepts with a variety of creative activities in a lesson that incorporates multiple steps to cover DNA structure, nucleic acids, and proteins. Pupils explore the history of DNA structure,...

Starting from a view of cells, a constructive simulation shows every step of building a new protein. It walks through transcription, translation, building amino acids, and folding the protein. Viewers control if it plays as a video or...

Picture a double helix as a twisted ladder. Scholars see this image through a simulation that allows young scientists to observe a small fragment of DNA in many different formats. They compare the models, colors, bonds, and strands as...

Fred Sanger created the first method of sequencing DNA in 1977 using chemical alterations. Learn more about the Sanger method with a brief animation demonstrating the replication, ordering, and piecing together steps in the process.

Students examine how traits are passed to offspring.  In this genetic reproduction lesson students develop a model of dna and learn about its structure, replication and function.

As a class, students work through an example showing how DNA provides the "recipe" for making our body proteins. They see how the pattern of nucleotide bases (adenine, thymine, guanine, cytosine) forms the double helix ladder shape of...
