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...

Can you identify mutations just by viewing DNA sequences? Scholars apply prior knowledge of DNA sequences to do just that in an engaging activity. They transcribe and translate genes, thus identifying the locations of mutations. Then,...

More than 90 percent of humans' DNA doesn't code for anything! Scholars watch a presentation as they answer questions relating to gene mutations. They read details, watch videos, and view animations supporting the concepts. The questions...

Cells demonstrate a life cycle like other living things, but what if death was no longer part of the cycle? Learn about the important balance requiring death to continue functioning. An online interactive introduces a group of scientists...

Learners investigate mutations and simulate their mutation while trying to collect food. In this mutations lesson plan, students pick an identified mutation out of a paper bag. They simulate their mutation while trying to collect food...

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 basics of mutation types and some potential effects of those are described and diagrammed here. Each detail is very clear and includes the labels and translation change exhibited. A great slideshow to expand on DNA replication issues.

How did the Ebola virus first infect humans? Young virologists examine genetic sequences from the 2014 Sierra Leone outbreak to find similarities during a riveting activity. Following similar methods used by MIT and Harvard, partners...

Curing cancer or finding the fountain of youth—the answer may be understanding the structure and function of telomeres. The relationship of telomeres to both aging and cancer have triggered aggressive research. A thorough lesson...

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.

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...

Fill- in-the-blank, labeling, and short answer questions make up this well-written cell division activity. Neat diagrams of chromosomes and dividing cells are included. Junior biologists show what they know about reproduction, meiosis,...

Students state the controls and variables of the Newcombe spread experiment. They state a hypothesis for the Newcombe spread experiment. Students distinguish between the characteristics of a preexisting mutations and those of an...

Mutation and auxotrophs are discussed. Next, the details of RNA transcription and how enzymes can control splicing and introns are given.

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...

What adaptations exist in order for icefish to survive the subfreezing temperatures of the Antarctic Ocean? Middle and high schoolers can find out through watching a related 13-minute video and performing a simple investigation to...

Biotechnology changes lives every day, but how did it all start? Learn about Cohen and Boyer's technique for recombinant DNA and the founding of this new scientific study. Then, scholars use the online interactive to discover how Hanahan...

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...

Why is diversity in biology so important for an ecosystem? Explore biodiversity, evolution, and natural selection with a presentation for your biology class. It features clear information, activities for further understanding, and...

Coloring pages showcase microbes—bacteria, viruses, and protists. Scholars have the option to download a coloring book and scavenger hunt or color the page directly on the computer. Three paragraphs describe each microbe. 

The living environment, from the interior of a cell to the complex relationships among populations, are queried in this final examination. Learners look at air pollution maps, diagrams of cells, population graphs, and drawing of cells....

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 course on the living...

Tne New York Regents High School Examinations are comprehensive and include various styles of questions, includingmultiple choice and the analysis of graphs. This particular version, the 2008 Living Environment exam surveys a variety of...

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 analysys questions, 73 of them in all. Topics range from...
