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.

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

High schoolers write an essay on the basic steps of the DNA replication process accurately enough to show a complete understanding of the subject. Finally, student correctly identify the polarity of the template strand and match the...

Students discover how DNA replicates through a PowerPoint lecture. Lesson includes a link to download entire PowerPoint lesson. Student understanding is evaluated with review questions.

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.

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...

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.

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...

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....

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....

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...

Young scholars work with a partner to answer any unanswer questions on their review sheet. They work in groups of 4 to make flash cards as study aides. Students play a review game for the remaining of the class period. The winning...

Young scholars demonstrate a working knowledge of cell interactions such as DNA replication, protein synthesis (transcription and translation), through active participation in a cooperative group.

Students view animations of DNA replication and transcription and complete a worksheet. In this genetics lesson, after watching on-line video clips to gather information about DNA replication and transcription, student teams identify...

Students explore and can explain genetic diseases, and how the central dogma plays a key role in genetic diseases. They comprehend what DNA probe is and how it is created and that there is an ethical component to biotechnology.

Students extract their own DNA from cheek cells. In this biology instructional activity, students explain the replication process. They identify the structure and composition of DNA.

Students review the structure and function of DNA, genes, and chromosomes and are engaged by a demonstration illustrating the relative size of DNA, genes and chromosomes. They also describe through analogy and model the structure and...

Students are organized into groups of four. On Day 1 they are given a worksheet about viruses and their effects on the evolution of a rabbit population. After about 30 minutes of group work, a class discussion of the material begins. ...

In this genetics worksheet, young scholars answer a variety of questions about inheritance, DNA, the genetic code, genes, sexual and asexual reproduction, mutations, protein synthesis and genetic engineering.

Learners examine DNA fingerprinting and polymerase chain reaction and how they are used in everyday life and for criminal investigations. They discover how these techniques can also be used to answer ecological and evolutionary questions.

Tenth graders investigate the chemical composition of DNA and RNA and how they work together to synthesize protein. They discover genetic codes, gene chromosome theory, and how the environment influences our appearance.

HIV mutates rapidly, making treatments challenging to find. Scholars learn about why it mutates so quickly and how scientists race to find treatments. The resource approaches the issue from both a molecular and evolutionary perspective...
