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...

With paper DNA patterns, budding biologists model translation and base-pair substitution within sequences. Through these activities, they examine how mutations can result in genetic disorders. The modeling that occurs is an enlightening...

Students investigate how mutations lead to changes in cell structure and function. They construct an oligonucleotide, identify a protein sequence, design a step-by-step mechanism of how they think cells repair damaged DNA, and prepare...

Ms. Strohfeldt did not omit anything when she designed this comprehensive lesson plan on DNA mutation and sex-linked traits. Begin with a pretest as an anticipatory set. Read a case history of the Clark family and the occurrence of...

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...

Young scientists demonstrate their creativity while completing several activities, to assess genetic variations and mutations. Instructors provide a list of options and scientists choose to write a comic strip, create a book,...

Different types of mutations cause unique types and degrees of muscular dystrophy. Scholars learn about the types of mutations and the impact on the body. They compare the location of the mutations and draw conclusions about how it is...

Adaptations must be made as environments change. This fabulous presentation features Icelandic icefish, a transparent, scaleless specimen that even has colorless blood. Genetics and adaptations concepts are explored as scientists study...

Does the human body evolve as quickly as human culture? With a stellar 15-minute video, explore the trait of lactose intolerance. Only about 1/3 of human adults seem to still have the enzyme lactase and therefore, the ability to digest...

The 2005 version of the Regents High School Examination in ecology is as comprehensive as previous years' exams. It consists of 40 multiple-choice questions on topics ranging from the structure of DNA to interactions within an ecosystem....

Students analyze DNA sequence differences between organisms in order to establish a reasonable picture of the evolutionary relationships between them. They take the role of molecular biologists and make genetic changes and constructing...

Students synthesize information gathered from the web on reading the DNA code. For this upper-level biology lesson, students use an online resource to gain information about DNA codes and then create posters on what they have learned....

The New York Regents High School Examinations are comprehensive and include various question formats, including multiple choice and graph analysis. This particular version, the 2008 Living Environment exam, surveys a variety of topics....

Biotech engineers discover that changes in the DNA code for cell wall formation can help create crops better suited for biofuel production. They extract DNA from wheat germ. They decode paper strips with codes and relate the activity to...

Young scientists learn about DNA replication through a video and model creation. They answer analysis questions before exploring the role of mutations and then complete a summative assessment.

In this biology worksheet, students review and answer different questions based upon the molecules of DNA and RNA. They look at the specific protein order of the DNA strand and its synthesis.

Research how DNA, the genetic blueprint of living organisms, plays an essential role in the continuity of life. High schoolers will summarize how their influence may very well effect the destiny of the population from one generation to...

Students study how cancer cells mutate and affect cell division.  In this investigative lesson students view a PowerPoint presentation learn the seven warning signs of cancer. 

High schoolers identify where mutations might occur and examine what effect those mutations will have through class discussion of DNA replication and cell division. Students then differentiate between mutations that affect individuals...

Students define the following terms: mutation, mutagen and give examples of how they work. They also define and illustrate a point mutation. Students define and illustrate a frame shift mutation and name two types of frame shift...

How do changes in DNA affect an organism? Scholars explore chromosomes, genes, DNA, and mutations by modeling the DNA of a strawberry. They build a DNA model, then manipulate it to show how changing the genes transforms the strawberry...

Students explore three lab experiments involving DNA, mitosis, and mutation. They complete activities and play games to review DNA, mitosis and mutation concepts. They build a DNA molecule and create flip cards representing mitosis in...

Students explore the structure of DNA and the process of DNA replication, describe the process of protein synthesis, recognize the importance of proteins in the human body, and look at how mutations affect protein synthesis.
