Students work with tools and techniques used in genetic engineering. They dissect a sample into fragments of DNA using restriction enzymes, sometimes called "molecular scissors". They sort these fragments, measure and analyze them according

In this biology worksheet, students identify the different types of reagents being used with the samples as part of an extensive lab experiment.

Students explain the importance and function of enzymes. They compare and contrast the processes of DNA replication and polymerase chain reactions. They practice using new vocabulary as well.

Are you looking for a way to measure cellular respiration? Try it with pureed potatoes. With some standard high school science equipment, biologists can perform an investigation and collect data surrounding byproducts of respiration. You...

Ninth graders examine the structure and function of biomolecules. In this food molecule instructional activity, 9th graders will examine various  types of biomolecules such as  carbohydrates, lipids, proteins, and nucleic...

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...

Young scholars create DNA models using colored construction papers. In this biology lesson, students identify enzyme restriction sites. They model how DNA plasmids replicate when taken up by a bacterial cell.

Students explore the basic process of natural selection and how people can manipulate that process today. The consequences of natural selection on daily life and the implications of evolutionary biology in basic and applied science is...

Students are allowed to strip away the cell walls of plants cells (using enzymes) and then observe the resulting spherical protoplasts (plant cells minus the cell wall). They see that plants cells indeed have a plasma membrane in...

Seventh graders explain the mechanism of digestion. In this biology lesson, 7th graders perform an iodine test to check for the presence of starch. They discuss how energy travels through the food chain.

Students explore how PCR works through various activities. In this biology lesson, students explain how PCR generate copies of DNA. They simulate the process using an online interactive website.

Students differentiate chemiluminescence from bioluminescence. In this biology instructional activity, students explain how fireflies and other animals emit light. They discuss the applications of engineered bioluminescence.

Students explain how cells reproduce. In this biology instructional activity, students transcribe and translate a gene. They discuss and compare their answers in class.

Is there such a thing as useful microbes? Get ready to perform experiments on applying microbes for wastewater treatment. The first installment of the three-part unit provides background information to prepare young engineers for two...

Got milk? Only two cultures have had it long enough to develop the tolerance of lactose as an adult. Learn how the responsible genes evolved along with the cultures that have been consuming milk. This rich film is supplied with a few...

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...

Students analyze various beverages to determine vitamin C content. Students research diseases resulting from vitamin C deficiencies and identify countries most affected.

Students observe demonstrations to show factors that affect rates of chemical reactions. In this rates of chemical reactions lesson plan, students investigate how catalysts, reactant concentrations, temperature and surface area affect...

Students use the exercise as a prelude to a "wet" lab or as a substitute for such a lab. It correlates well with colony transformation labs. This lab is recommended for students what have difficulty with the abstractions that genetic...

Students extract DNA from their own hair roots. They run an electrophoresis gel to examine patterns of their DNA along with standard DNA. The experiment is based on a crime scene scenario.

Students observe the experimental process called bacterial transformation and demonstrate phenotype changes in bacteria that have been transformed with an antibiotic-resistance gene and a metabolic marker. They create a luminescent...

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.

Become an immunologist for the day. Scholars elicit the use of the enzyme-linked immunoabsorbent assay (ELISA) to diagnose an infectious disease. Through the process, they learn about the immune system response to infectious diseases.

Students use the prelab as an introduction to the importance of DNA fingerprinting- a form of identification that us being accepted by both scientific and leagl experts. They prepare a gel for electrophoresis. DNA fragments, which have...
