High school learners read and discuss an article about genetic ancestry and genetic ancestry testing. They complete a paper and pencil activity that mimics the function of a DNA microarray and consider the ethics of genetic testing in...

A pinch of adenine, a dash of thymine and ta-da, you have life! Well, it's not quite that simple, but through this series of activities and experiments young scientists learn about the structure of DNA and how it contains the recipe...

Your scientists-in-training extract DNA from a banana. Then, they wrap it around a glass rod in order to view the threads of DNA. They draw their observations.

In order to understand DNA fingerprinting, advanced biology aces divise a crime scenario and analyze three different samples of lambda DNA. This creative lesson plan provides practice with micropipettes, electrophoresis boxes, and other...

Uncover the basics of DNA structure through exploration activities. Collaborative groups build DNA models and recreate the process of replication. Then, using plant cells such as peas or strawberries, they extract a DNA sample.

Learners experience a "hands-on" activity to get visual evidence of the physical nature of DNA and the process of DNA purification. They explore one method of chromosomal DNA isolation and DNA extraction.

DNA molecules hold the secrets that make us unique. The fourth of 12 lessons explores the structure of DNA by building candy models. After building the models, young scientists break their models to begin the process of DNA replication....

Students explore DNA. They work in groups and mix prepared detergent/ salt solution, meat tenderizer solution, Fleischman's yeast and water to extract DNA from yeast. Observations are recorded.

Students study the process of DNA Fingerprinting and how DNA Fingerprinting is used in solving crimes. They examine a crime scenario that involves collecting DNA Fingerprinting information from blood collected at the crime scene. They...

Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...

High schoolers are able to distinguish between transcription and replication. They are able to distinguish between DNA and RNA. Students name some of the proteins and enzymes used in replication and transcription. They are able...

Biology stars extract DNA samples from beef thymus and then examine its properties. They use enzymes to digest the DNA samples, and then use electrophoresis to separate fragments. Finally, they discuss methods and principles of...

Students discover the basic structure of DNA and its function in living organisms by conducting an experiment in which they extract DNA from bananas using a lysis buffer solution.

Why do the bases in DNA pair up the way they do? Unravel the mystery of the double helix in a virtual lab. Young scientists follow in the footsteps of Watson and Crick to determine the free energy associated with DNA base pair binding....

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...

Students create a model of DNA and simulate replication with their models in an activity that uses licorice, colored marshmallows, and toothpicks. Students also label a diagram of replication and indicate major parts of the DNA molecule.

How effective are cells at repairing UV damage? An inquiry-based lesson has learners experiment with organism by exposing them to various levels of UV light and then examining their DNA after a period of time. Pupils test different...

Your class is bound to be fascinated by this virtual lab! Young biochemists explore molecules that bind to specific sites on the DNA molecule through a skillful simulation. The lesson challenges learners to create a DNA-bound solution...

Students are able to construct a candy model of DNA. They are able to list all of the parts of DNA that they investigated earlier. Students are able to describe what each part of DNA does. They create an edible model of DNA strands.

Students review what they already know about DNA. After reading an article, they discover a new technique to map the course of evolution. In groups, they create ways to present this material to younger children and research DNA's uses.

Students build their own DNA molecules using candy. In this science lesson plan, students build DNA molecules using licorice and gumdrops. The lesson plan includes the use of streaming videos from the teacher's domain.

What do cats and human DNA have in common? The second lesson plan of a series focuses on the mapping of mammal genomes. Scholars learn about the structure of DNA as they compare the chromosomes of humans and felines.

Learners extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students explore DNA restriction mapping. They cut pieces of paper into lengths representing those produced when specific enzymes are used to cut a strand of DNA.
