This multimedia resource, part of the NC Science Now series, describes how researchers at the Hammer Institutes and UNC Chapel Hill are collaborating to find out why a small percentage of the population may have a dangerous reaction to a medicine while the majority of people are not affected. Components of this resource include a video and a related blog article. Links to these components are provided on the page under the heading "UNC-TV Media." Discussion questions are also included.
The goal of this lesson is to introduce students who are interested in human biology and biochemistry to the subtleties of energy metabolism (typically not presented in standard biology and biochemistry textbooks) through the lens of ATP as the primary energy currency of the cell. Avoiding the details of the major pathways of energy production (such as glycolysis, the citric acid cycle, and oxidative phosphorylation), this lesson is focused exclusively on ATP, which is truly the fuel of life.
In this inquiry-based activity, students investigate how brine shrimp populations can survive in some of the harshest environments. Students subject brine shrimp cysts to extreme conditions to evaluate the hardiness of these creatures.
In this activity, students play a game that simulates the carbon cycle. During the activity students will compare the carbon cycle before and after the industrial revolution.
In this simulation activity, students will collect data, formulate a hypothesis, and run a series of experiments in order to discover the interplay between natural selection and sexual selection in a wild population of guppies.
Students will use an online calculator to estimate their household's carbon footprint and explore various actions to reduce it.
Students will investigate comparative anatomy of organisms - visually, verbally, and kinesthetically - and how these organisms have changed through adaptation and evolution. To meet this objective, each group of students will perform seven independent activities at seven separate stations.
This webpage provides graphics illustrating adaptive structures and adaptive behaviors of unicellular organisms.
This assessment resource checks for student understanding of population density and the factors that can cause fluctuations in population.
Students examine exponential and logistic growth, identify carrying capacity, distinguish between density-dependent and density-independent limiting factors, apply the population model to data sets, and determine carrying capacity from population data.
In this interactive module, students examine exponential and logistic growth, identify carrying capacity, distinguish between density-dependent and density-independent limiting factors, apply the population model to data sets, and determine carrying capacity from population data.
Students will learn about the role of DNA and RNA in protein synthesisand gain an understanding of transcription and translation to create an amino acid chain.
Students investigate factors that limit the spread of invasive species in the United States. They compare the spread and limiting factors of three classes of invasive species - insects, plants, and aquatic invertebrates - through data sets from the National Atlas and readings on invasive species issues. This activity is part of "Investigating Your World With My World GIS," a set of activities designed for use with My World GIS software (which can be downloaded at www.natgeoed/myworldgis) to help students learn key content and practice spatial problem solving.
In this biology lesson with math and ELA integration, students use real rock pocket mouse data to illustrate the Hardy-Weinberg principle.
In this activity students build protein bracelets using beads with different colors and shapes that represent the different amino acids.
In this lesson, students will investigate a sample of pond water and compare and contrast the key characteristics of protozoa found in the sample. They will then design inquiry-based experiments that test a number of ecological problems.
This lesson will expose students to some of the problems amoebas have caused to residents of Florida. Studies have shown that virulent strains of amoebas from the genera Naegleria and Acanthamoeba have the ability to grow at high temperatures, while non-virulent strains are unable to grow at normal or elevated body temperatures.
