Learners 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...

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.

High schoolers discuss a bacterial experiment they previously performed and complete a pre-assessment. They participate in a lecture discussion given by the teacher through PowerPoint and then complete a cartoon worksheet and...

Learners discuss methods used by forensic scientists and the basics of DNA and how it can be used to identify an individual after reading an article from The New York Times.

Students describe the fundamentals of DNA such as structure and replication. Given a picture of a gel, they circle the band that represents the smallest DNA, the largest DNA, and show which DNA sources are the same.

A terrific lesson focused on the design process. It begins with a presentation, "Design: Solve a Problem," which lists the steps of the process and then introduces the specific challenge: to build a device that measures wind speed....

Students examine various genetically engineered foods by lecture and library research. They are then placed in groups of two to produce their ad and make a presentation on a food they have developed.

Students study the effects of the Great Exchange on the Americas.

Fifth graders understand that traits are inherited and change over time. In this physical traits lesson, 5th graders compare produce items for similar traits. Students create large graphs to show their results. Students discuss genetic...

Tenth graders explore the different health risks associated with human papillomavirus. In this health science lesson, 10th graders identify different ways to prevent viral and bacterial infection. They research and develop an awareness...

Learners participate in a review of diffusion and the basic properties of the cell membrane before exploring the process of osmosis in a lab activity. Using shell-less eggs that have soaked in various solutions, students make...

Students conduct the Biuret Test and the Bio Rad Protein Assay. They examine the spectrophotometer and graph molecular weights and the concentrations of the proteins investigated. They prepare solutions for the Bio-Rad test and use the...

Learners perform an experiment in which they test foods for the presence of proteins, carbohydrates, and lipids. They identify the molecular structure of each type of biomolecule and then discuss how biomolecules relate to nutrition and...

Learners explain the concepts of what DNA is and where it is located in a cell, identify the two types of molecules that make up the rungs of a DNA molecule and identify the two types of Purine and Pyrimidine molecules

Students study about chromatography, a process used to separate mixtures. They see that chromatography is used to detect, separate or purify different substances. This nice instructional activity results in a beautiful t-shirt for each...

Students grow bacteria cultures on agar in petri dishes and do a plate count. They participate in a yogurt making lab to see how bacteria produce lactic acid. They prepare a recipe and identify fungi, fermentation and the role of...

Students complete various exercises and activities as they examine the procedures involved in organ transplants and the ethical issues surrounding organ donations.

Students complete a variety of activities as they examine the ethics of acquiring and distributing fish as a food source. They touch on the ethics involved in genetically modified salmon, as well.

Students analyze the results of a hypothetical cloning experiment using a restriction endonuclease map obtained from an on-line data source. They answer the question, "How can I tell if the DNA I have obtained from this hypothetical...

Student observe and quantify the respiration that occurs in yeast-molasses cultures. They complete an effective experiment in order to examine how to think critically about the results.

Students listen to an explanation of yeast cells and how they effect bread and beer. They discuss the ways alcohol affects the human body and participate in an indirect observation about cell respiration in yeast-molasses cultures.

Students predict possible phenotypic and genotypic outcomes for avariety of common plant hybrids. They review and explain the characteristics of dominant and recessive traits and explore Mendelian genetics. Students plot the possible...

Students are shown why they should care about evolution. They become specialists in one sphere influenced by evolution and then share their findings with their group. Students are lead into a class discussion, so that each student can...

Students engage in solving a logic problem based on real organisms and real data. They develop phylogenies for seven related populations of lizards living on the Canary Islands.
