Neurons in Parietal Cortex Are Active During Straddling
How do scientists know which parts of the brain various functions use? With the help of an animated cat, viewers observe this process. They listen to the activity of one neuron as the cat steps over an obstacle and hear when the neuron...

UV, Mutations, and DNA Repair
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...
Curated OER
Infectious Disease Case Study
Learners list the steps an epidemiologist takes to detect a pathogen. They role-play as scientists as they investigate the cause of the outbreak in Japan during 1996.

How Can You Predict the Characteristics of an Unborn Baby?
Students compare three sets of unlabeled human chromosomes and gather related data, trace chromosomes to pair them, and make observations about them.
Curated OER
DNA Fingerprinting
Students 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.

How do things flow in and out of a cell?
High schoolers revise thier partner's essay. They also write the second draft of their essay for homework. Students use the Protein Explorer web site to visualize molecules, ATP, DNA, proteins and lipid bilayer. They are able to see...

Using VNTR Analysis to Identify Guilt at a Crime Scene
Students collect DNA from cheek cells. They compare and contrast the processes of DNA replication and PCR. They discuss how this information can be used to determine guilt at crime scenes.
Curated OER
The Cytochrome-C Lab
Students examine a method biologists use to try to determine relationships. They examine how amino acid sequences have been determined for a number of proteins, and how scientists can make inferences about DNA based on the amino acid...
Curated OER
Lesson on Proteins
Students examine the importance of proteins including their function and structure. In this protein lesson students play a game to help them better understand proteins.

Biotechnology and The Chocolate Milk Cow
Students discuss new discoveries that have resulted from the use of recombinant DNA technology and otehr biotechnology. In groups, they create a transgenic cow capable of producing chocolate-flavored milk.
Curated OER
DNA Extraction Lab
Students extract DNA and test for its presence from unroasted (raw) wheat germ using a prescribed procedure. They modify the procedure to provide a less expensive, easier method. They also extract DNA from different available plant,...
Curated OER
Who Is It?/Who Done It?
Students conduct an experiment that allows them to assess individual differences in random DNA sequences and apply those differences when solving a forensic problem. After discussing the polymerase chain reaction and its use to identify...
Curated OER
Genetic Ethics Debate
Students select topics relating to bioethical questions which they research and debate. They, in groups, select topics and are given two to three weeks to research their topics, taking advantage of their school libraries and local public...
Curated OER
Sociobiology: Heredity Factors
Students examine DNA replication and how proteins are synthesized from DNA codes and continue to explore the effects of genetics in additional lessons. Among the topics covered are: protein synthesis, cell chemistry, environmental...
Curated OER
The Effect of Natural Selection on Genes, Traits and Individuals
Rotating through five stations, evolutionary biologists explore the question of how changes in DNA facilitate the changes in a population over time. High-quality, colorful cards of animals, skeletons, skulls, and DNA sequences can all be...
Curated OER
Pesticide Watch Card
Students examine human health by identifying dangerous pesticides. In this agriculture instructional activity, students research the food production system in the United States and discuss dangers such as pesticides, chemicals and...

Shedding a "Little" Light on Cancer Surgery
Many types of cancer treatments now depend on nanotechnology—a big "little" discovery. Scholars begin by removing "malignant" tissue from simulated brains, one using fluorescent markers thanks to nanotechnology and one without. This...
Khan Academy
Introduction to Heredity
Young scientists generally love to learn how certain traits can be explained by a direct combination of alleles from their parents. Here, they can examine how a phenotype is often expressed when one allele is recessive and the other is...
National Center for Case Study Teaching in Science
Abracadabra
How has Magic Johnson managed to stay so healthy, despite being HIV-positive for over 20 years? If you have ever taught about HIV and AIDS, you have most likely been asked such a question. By examining a case study and role-playing as...

Measuring Circadian Activity in Drosophila
How many hours should be in a day? One species of drosophila naturally prefers a 24.5 hour day, while another strongly prefers a 19-hour day. An animation and graph share data from each of these species when exposed to the typical light...
Curated OER
Genetically Modified Organisms
High Schoolers complete a variety of activities as they examine the ethics of (and take a position concerning) genetically modified organisms in the field of agriculture. They complete a PowerPoint demonstration to go along with the unit.
Curated OER
DNA Fingerprinting
Students study the process of DNA Fingerprinting and how DNA Fingerprinting is used in solving crimes. They examine a crime scenario that involves collecting DNA Fingerprinting information from blood collected at the crime scene. They...

When Insects First Flew
Insects developed wings and the ability to fly earlier than any other animal—when exactly did that happen? Scientists know this fact but struggle to explain when insect wings developed and how this entirely new structure appeared. PBS...
