A stress echocardiogram can help a doctor see how the heart responds to exercise. This tutorial explains how the test works and its risks and benefits.

This site from the Nobel e-Museum contains a speech, originally given in 1905, in which Count K.A.H. Morner praises Robert Koch for his contribution to the world of medicine and awards Koch with the Nobel Prize.

Discusses how the structures of the noseinteract to produce our sense of smell.Has links to lab activities and teacher lessonson this topic.

This activity allows students to explore and reflect on circadian rhythms in themselves, influences of their lifestyle on those rhythms, investigate them in a scientific manner, and draw conclusions of their findings in a lab report format with data tables and graphs.A 2+ week take home lab activity with a lab report and graphs at the end. Can be used to explore the scientific method, physiological cycles, and how to share scientific knowledge.

Read about the 1959 co-recipient of the Nobel Prize in Physiology -- Severo Ochoa -- who contributed to the "discovery of the mechanisms in the biological synthesis of ribonucleic acid and deoxyribobucleic acid."

Sports physiologists understand the body's anatomy and the biomechanics of how bones and muscles work together. These scientists can help improve athletes' performance and help keep them healthy. But many young athletes are unaware of how to play and move safely and end up injured. Learn more about this science and why all of us need to keep moving.

A good description of the growth and changes in plants from the seed through the adult plant. College level discussion that includes the chemicals involved in the regulation of plant growth.

Understanding Biodiversity presents an overview of biodiversity, its importance and relevance to humans, all living things, and the Earth. It includes species pages and a template to engage and involve students in real-life data collection.

Students are presented with the unit's grand challenge problem: You are the lead engineer for a biomaterials company that has a cardiovascular systems client who wants you to develop a model that can be used to test the properties of heart valves without using real specimens. How might you go about accomplishing this task? What information do you need to create an accurate model? How could your materials be tested? Students brainstorm as a class, then learn some basic information relevant to the problem (by reading the transcript of an interview with a biomedical engineer), and then learn more specific information on how heart tissues work their structure and composition (lecture information presented by the teacher). This prepares them for the associated activity, during which students cement their understanding of the heart and its function by dissecting sheep hearts to explore heart anatomy.
