Are you an XX or an XY? Budding scientists learn about cellular fertilization and the determination of gender in a thorough online lesson. They follow their study with a set of interactive reflection questions.

Some genes link to others that have implications for inheritance. A set of resources lead pupils through the history of this discovery. They explain how chromosomes recombine and which parts are more susceptible to this linkage....

Some traits only exist in males and some only in females. Pupils learn how the location of genes on sex chromosomes determines them using an interactive lesson. An animation illustrates how scientists know this to be true and shows how...

What's your type? Genetically speaking, of course! Immerse your class in the world of karyotypes through an insightful activity from the K20 Center. Scholars take on the role of genetic counselors to determine the karyotype of offspring...

What could be more real life than a biology course? Mt. Hood Community College offers a complete biology textbook with an emphasis on genetics. Topics range from DNA replication to biotechnology and inheritance patterns.

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.

Students explore how DNA fits into chromosomes and how chromosomes relate to the human body. Students learn about DNA replication and protein synthesis and model these two processes.

Young scholars explore how DNA fits into chromosomes and how chromosomes relate to the human body. They learn about DNA replication and protein synthesis and model these two processes in Web activities.

Students list differences between DNA-related terms and create a simple DNA circle map. They order terms including human body, organ, tissue, cell, nucleus, etc. from largest to smallest. They discuss differences and similarities among...

Learners observe a model of DNA and answer probing questions like, "What does this model represent?" They then work in small groups to construct an accurate model of DNA per rubric provided and present to the class explaining their model...

Students investigate DNA by doing a hands on activity.  In this activity lesson students participate in a lab that allows to explore DNA and chromosomes. 

Students are introduced to mapping by crossover frequency. Genes travel as packaged trains on chromosomes. They use this experiment, genetic mapping assignment, that allow students to quickly complete the assignment and yet examine the...

Advanced biology masters take a close look at DNA and the scientists who contributed to our understanding of this complex and powerful molecule. They answer 21 questions about DNA structure, replication, and repair. This can be used as a...

Today researchers identify a gene suspected of causing a genetic disease in a matter of days rather than years, thanks to the Human Genome Project. Young scientists learn about the Human Genome Project and the scientists who designed the...

Mutations are not just deformed creatures we see in movies—they happen every day! Scholars study the different types of genetic mutations in the 12th installment of a series of 18 lessons. A creative activity uses candy and other food...

Six different chromosome activites introduce biology aces to heredity, chromosomal abnormalities, sex-linked traits, and the human genome. The hands-on activites are fairly simple for the teacher to prepare and will prove to be both...

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....

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...

Take your advanced biology learners across the great divide: where cells divide, that is! Although it was created as a chapter reading guide, having your class complete this worksheet is not only appropriate, but also highly valuable in...

Young scholars engage in a variety of activities designed to facilitate the understanding of DNA. Activities include preparing human chromosome spreads, separating a mixture of dyes using gel electrophoresis and extracting DNA from onion...

Students build DNA strands and practice base pairing rules using an interactive website in this technology-based lesson for a high school science class. This lesson includes links to the interactive website, a worksheet, and a video...

Students draw a picture of a person from popular culture, then "clone" it using printing techniques in this Art lesson plan that tackles the questions surrounding cloning, DNA, and current scientific techniques. An emphasis is placed on...
