In this lesson, students read an essay, "It's All in the Numbers," about the rapid spread of HIV particles in the body, and learn how to calculate exponential growth using pennies to model HIV particles.
In this lesson, students will create scale models of microorganisms and compare the relative sizes of common bacteria, viruses, fungi and protozoa using metric measures. Students will learn that microbes come in many different sizes and shapes, and frequently are measured in micrometers.
In this lesson, students will estimate risks associated with different events and compare their estimates to the real probabilities.
In this lesson, students learn that bones and muscles must work to maintain or increase strength and endurance. Students will measure the effects of physical stress on the muscles of their hands, collect and record data, and graph results.
In this lesson, students will use statistical tables of HIV/AIDS data to create presentations about occurrences of HIV/AIDS in the United States.
In this lesson, students will measure their heart rates after a variety of physical activities and compare the results with their resting heart rates, and with the heart rates of other students in their groups.
In this lesson, students will use evidence to determine whether a patient has a cold, flu, or strep infection. In the process, they will also learn about the differences between viral and bacterial infections.
In this lesson, students will observe onion cells and an Elodea leaf. With these examples, students will be able to see basic parts of cells, including the nucleus, cell wall, and chloroplasts.
In this lesson, students read an essay, "The Deadly Cycle," about HIV viral replication, learn the parts of a single HIV particle, and investigate the HIV replication cycle in a host cell.
In this lesson, students learn about microbes and the diseases associated with them, learn how diseases are transmitted and impact society, and create art projects representing the diseases they have studied. They also learn that many diseases caused by microbes have resulted in serious debilitation and/or loss of human life.
In this lesson, students collect, grow, observe and compare bacteria and/or fungi in petri dishes, learning that microbes are everywhere and can grow rapidly on sources of food and water.
In this lesson, students read about six milestones in the history of microbiology, create a timeline of events, and learn that many scientific advances become possible only after appropriate tools and techniques have been developed.
In this lesson, students read an essay, "Portrait of a Killer," about the emergence of HIV/AIDS, and learn about the basic structure of the virus by making three-dimensional paper models of an HIV particle.
In this lesson, students are introduced to the structure of muscles. Students will compare and contrast a piece of yarn to a cooked piece of meat.
