Humans have taken communication to every corner of the Earth, yet our bodies, at the cellular level, have communicated without technology for millions of years. Learners view the variety of ways cells can communicate, whether right next...

Human biology or genetics learners apply their knowledge to a unique situation: two newborn baby girls being possibly switched in the hospital. The engaging activity ends with a Punnett squares assignment in which pupils evaluate whether...

Sal explains how every cell in our body is able to present a sample of the proteins inside of them, in order to signal that is compromised. A good summary to help students understand the complicated system of alerting a 'T' cell and...

Jump into the action and help antibodies defend against an antigen attack! Investigators match antibodies with antigens to model the body's identification and recall of specific pathogens. Young biologists also recognize that each...

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...

A very timely lesson plan looks at the social and political factors that affect the spread of disease. Using the 1918 Influenza Pandemic as a case study, pupils research factors that influenced the spread of the disease, including the...

Is it possible for another flu outbreak like the Spanish Flu in 1918? A video lesson explains the factors that affect the spread of a virus and its effect on a population. The narrator describes the structure of the different virus...

How do bodies fight infections and illnesses? An animation of the way T cells clone to fight an infection provides many details. The resource also provides an excellent written introduction and ideas for how to ensure pupils understand...

Biotechnology is big! Introduce the uses of biotechnology to science scholars with a fascinating, fact-filled unit. The first installment in a series of four biotechnology units covers the role biotechnology plays in human and...

How does your body know when to present an immune response? Viewers observe how antigen presentation triggers the response and how this treatment helps attack viruses before they spread. The video also discusses the challenges of...

You won't be able to resist the content of a great presentation! Young immunologists discover the variety of cells involved in keeping our bodies free from pathogens with a resource that contains both slides and video clips. The included...

Our body manufactures antibodies that are the exact shape for the antigens it encounters. The simulation shows a 3-D model of an antibody and antigen pairing. It allows young scientists to explore the complementary shapes.

Does your blood type matter? The video explains the four main blood types and the importance of knowing blood types when performing transfusions. The interactive reviews the information with a quick graphic organizer and questions.

Teach your class about human blood and explain why donation is so important using the 29th video in a series of 47. Learners explore the basic components of blood, how cuts stop bleeding, and how antigens determine blood types. 

Young scientists learn the importance of knowing blood types and their compatibility. The instructor in the video explains each type of blood and their antigens and antibodies, and then differentiates between AB blood and Rh blood types....

Flu vaccines work by calling on the immune system to produce antibodies against the virus without actually infecting the individual with the flu. Here class members see how a virus enters cells and the body defends itself. The instructor...

Young historians view and analyze photos and documents from WWII that are related to blood transfusions and blood plasma. A demonstration of correct and incorrect blood donors visually shows the importance of knowing blood type. After...

Whatever you do in life, always give 100 percent—unless you are donating blood. A video explains how to solve Punnett squares with multiple alleles, in this case blood types. It includes what happens if the wrong type is added, which...

Can you catch the same cold twice? Elementary and middle schoolers learn about what happens when a virus attacks their bodies, and how the immune system never forgets a virus, with an entertaining comic book. The packet includes...
