Is DNA still present after picking fruit or cooking vegetables? Biology scholars extract and collect DNA strands in an impactful lab. Working groups prepare their samples and compare their results to negative and positive standard...

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...

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...

Lead your young scientists into an exciting world as they participate in a role play and experiment focused on proteins and DNA. After researching the Central Dogma of Biology, individuals or groups participate in a classroom...

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson to teach budding scientists how this happens. Using a set of nucleotide cards, learners become the DNA and work to create matching strands...

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....

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.

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.

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...

Get up close and personal with DNA! A two-part hands-on activity has learners extract DNA from a small organism and then their own cheek cells. Scholars then explore DNA replication using questions to guide their analyses.

It has been decades since the discovery of DNA. Still, activities such building this DNA model allow blossoming scientists to better understand the components that form this overall structure. During this activity, they will also...

Although not particularly educational, here is a creative group activity in which high school biologists will use their imaginations to create a new life form combining characteristics from existing life forms. Each group must come up...

Students create DNA models. Using puzzle pieces to represent the parts of a DNA strand, they put together a segment of DNA. Once everyone has completed their individual strand, they being linking with other students using tape. Class...

Young scholars describe DNA and the roles in which engineers are involved with the human body.  In this DNA lesson students participate in a class demonstration. 

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.

High schoolers interpret different DNA fingerprints, then do a jigsaw activity to explore other uses of DNA forensics. They listen to a radio program about using DNA as evidence and discuss the limitations of and problems with DNA testing.

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 extract and observe a visible amount of DNA from Escherichia. coli cells. They discuss the properties of DNA. Confirmation of the presence of DNA by a reaction with an indicator is confirmed within this instructional activity....

Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

Can science put an end to the poaching of endangered species? Show your young forensic experts how biotechnology can help save wildlife through an exciting electrophoresis lab. Grouped pupils analyze shark DNA to determine if it came...

Students discuss DNA Fingerprinting and gel electrophoresis before participating in a crime solving activity. Students simulate their DNA using adding tape and complete the steps necessary to do a gel electrophoresis. They discuss the...

Learners create models of DNA and RNA using string and beads. They use beads representing the four nitrogenous bases of DNA to create a portion of a strand of DNA, and it's corresponding RNA. Then, students examine how many of their...

Learners describe the structure of the double helix, explain how DNA copies itself, and recognize that the sequence of DNA is what makes each individual unique.
