It's all in the cards. Using cards to simulate a disease's attack on the immune system, pupils develop an understanding of how the immune system and pathogens react to each other and why at times the pathogen wins. Groups play a game to...

Attack the pathogen from within. Learners delve deeper into the immune system and find out about the adaptive immune system such as T and B cells. Groups create graphical models of the adaptive immune system along with a multimedia...

It's virus-fighting time! Pupils learn how viruses attack and reproduce and how the immune system works to protect the body. They identify unfamiliar terms and tissues and organs of the immune system. Working in small groups, scholars...

The earth has a love-hate relationship with carbon. Learners complete a series of nine lessons that begin with an examination of the role of carbon in Earth's systems. They then relate changes in climate and weather to changes in the...

AP® free-response questions are often challenging for scholars. Give them practice writing free-response questions using former questions from the AP® Biology exam on topics such as genetic mutations, cellular respiration, evolution, and...

What is the best way to prepare for an AP® exam? Learners become familiar with the AP® Biology exam by completing a full-length practice exam. The AP® test prep by the College Board contains multiple choice, grid-in, and free-response...

What do lab tests reveal about a patient's health? Scholars perform a simulated urinalysis on two different patients by testing color, pH, glucose levels, and protein levels. Then, they compare their findings to what they know passes...

How diverse are living things? Individuals explore topics such as cells as the foundation for life, cell division and genetics, molecular biology, and animal reproduction using an open resource Biology textbook. They learn key terms...

Experimental design can make or break an experiment. Young scholars analyze the pulse-chase analysis procedure by studying the Meselson-Stahl experiment. Using a video presentation, they discover how the pulse-chase analysis led to the...

What does it take to create a scientific theory? Learners attempt to answer the question by studying the work of Charles Darwin and Alfred Russel Wallace. While watching a video, they track observations from each scientist and then look...

One important skill in analyzing scientific evidence is identifying facts versus opinions. Scholars identify pieces of evidence from the film The Day the Mesozoic Died and then discuss this evidence in small groups at the end of each act...

What, exactly, causes lactose intolerance? Scholars view a video describing a Finnish study that determined why some people are tolerant while others are intolerant. They then use the data from the study to reenact the experiment and...

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...

Are sickle cell disease and malaria related somehow? Scholars learn about both illnesses and the hypotheses that they are related. They discuss, view a video, and answer questions to demonstrate understanding. The resource includes an...

While many mutations are neutral, those that appear advantageous increase in frequency in a population. Scholars use illustrations to make predictions about populations of mice. They follow it up with a video to confirm or refute their...

The proteins inside a cell determine the shape of the cell. While most red blood cells have a circular shape, those with sickle cell take the shape of a sickle. This change in shape causes multiple issues in the system. Scholars solve...

The Hardy-Weinberg principle states that alleles and genotypes remain constant in the absence of evolutionary influences. Scholars complete a simple hands-on activity applying the Hardy-Weinberg principle to sample data. They observe how...

Everything evolved from a common ancestor, but how did modern plants and animals develop so many more genes? Scholars use an online interactive to learn about the process. They begin to understand common genes with an animation, multiple...

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...

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...

Personalized medicine prevents many trial-and-error scenarios when time counts the most. Learn how gene expression and screening genomes improves health outcomes in cancer patients, those with auto-immune disorders, and more. An online...

Regulations exist in many places from business to schools, but what about in our genes? Learn about gene regulation with an online interactive. It uses an animation to introduce the topic, many photographs of the scientists best known...

Some people have a natural ability to jump, but did you know DNA also naturally jumps? Learn about the fun habit by looking at the research of a pioneering female scientist. Barbara McClintock fought prejudice and surpassed her mentors...

Roy John Britten easily earned a PhD in nuclear physics—but he found painting with water colors too difficult. Young scientists learn about Britten's life, career, and research with an online interactive. They read a biography, view...
