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...

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....

Before a cell replicates, its DNA must replicate. Take advantage of a hands-on guided lesson plan 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....

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...

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....

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...

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...

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 explore the Sanger sequencing method which produces a nested set of radioactive fragments from a template strand. They simulate the Sanger method of sequencing DNA, both visually and kinesthetically.

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...

Students conduct an experiment that allows them to assess individual differences in random DNA sequences and apply those differences when solving a forensic problem. After discussing the polymerase chain reaction and its use to identify...

Investigate the relationships between different deep-sea organisms by DNA sequencing. A worksheet provides instructions for DNA sequencing and space to work. They simulate gel electrophoresis by cutting out paper "DNA strands."...

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,...

Times have changed—and so have science practices. An introductory lesson describing the components of DNA begins with a discussion of the discovery of DNA and its perception in different cultures and genders. Scholars then learn about...

Students simulate the Sanger method of DNA sequencing using color pop-beads as a representation of nucleotides and dideoxynucleotides. Students assemble DNA sequences and run their sequences through a "sequencing gel" and sketch what...

Students explore gel electrophoresis using paper models. They model DNA sequences and shade the boxes on their Gel Electrophoresis Sheet which represent the individual fragments.

Tenth graders work with a partner, and copies of the attached worksheet "Amino Acid Codon Table" They discuss ways an organism, obtains and uses proteins. Students view a teacher prepared DNA strand banner, and record the complementary...

Students see DNA as a physical building block of organisms and comprehend the basic structure of DNA and the specific components in its structure. They can explain the specific nature of base-pair matching in DNA and that DNA bases form...

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...

Emerging ecologists need a full understanding of life, from the inner workings of a cell to the complex relationships among organisms. This examination is meant to assess high schoolers after an entire year of courses on the living...

Environmental science enthusiasts show what they know at the end of the year by taking this full-fledged final exam. They answer multiple-choice, graph interpretation, and essay-analysis questions, 73 of them in all. Topics range from...

The living environment, from the interior of a cell to the complex relationships among populations, is queried in this final examination. Learners examine air pollution maps, cell diagrams, population graphs, and drawings of cells. They...

Students 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.
