From Lake to Tap
In this activity, students will use a tutorial on the U.S. Environmental Protection Agency's website to learn about how surface water is treated to make it safe to drink.
Lighting Up: Analysis Of Yeast RAS Genes Using A Chemiluminescent Southern Blot Procedure
Genomic and plasmid-encoded RAS2 genes from Baker's and brewing yeast strains will be analyzed using a shortened Southern blot procedure employing chemiluminescence. Unique parts of this procedure are the gravity-driven "upside down" transfer and a rotisserie-like hybridization oven, which greatly facilitate shortening the transfer time to 45 minutes and the hybridization step to 60 minutes. Chemiluminescence obviates problems associated with radioisotopes without sacrificing sensitivity: the pl
Ranking the Rocks: Lesson
This lesson develops the real-world connections and relationships between the rock properties found in Lesson 5 and the important engineering properties for designing and building caverns (or tunnels, mines, building foundations, etc.). The student teams will use importance factors called "desirability points" to mathematically determine the overall best rocks to build caverns within.

Taylor W. Meloan Interview
Taylor W. Meloan, former interim dean and distinguished professor emeritus of marketing at the USC Marshall School of Business, shares insights and observations gained during 40 years of service to USC. Meloan joined USC in 1959 and was involved in teaching, research, publishing, community outreach and administration at both the department and university levels. Meloan was interviewed by Alan J. Rowe on May 18, 2000, as part of the USC Emeriti Center's H. Dale Hilton Living History Project.
Does Your Chewing Gum Lose Its Flavor?
In the first part of the activity, each student chews a piece of gum until it loses its flavor, and then leaves the gum to dry for several days before weighing it to determine the amount of mass lost. This mass corresponds to the amount of sugar in the gum, and can be compared to the amount stated on the package label. In the second part of the activity, students work in groups of four to design and conduct new experiments based on questions of their own choosing. These questions arise naturally

Population Growth in Yeasts
This lesson is the second of two that explore cellular respiration and population growth in yeasts. In the first lesson, students set up a simple way to indirectly observe and quantify the amount of respiration occurring in yeast-molasses cultures. Based on questions that arose during the first lesson and its associated activity, in this lesson students work in small groups to design experiments that will determine how environmental factors affect yeast population growth.

How Clean is that Water?
This lesson plan helps students understand the factors that affect water quality and the conditions that allow for different animals and plants to survive. Students will look at the effects of water quality on various water-related activities and describe water as an environmental, economic and social resource. The students will also learn how engineers use water quality information to make decisions about stream modifications.
Matrix Concepts -- Multiplying Matrices
This module covers multiplication of matrices.

PediNeuroLogic Exam: 2 1/2 Years Old: Behavior/Mental Status - Names Pictures
Later on in the exam she cooperates enough to demonstrate that she is able to name all five pictures that are shown to her, which is the next developmental level above pointing to them. The next level after naming would be identification by the action of the picture, such as asking which one flies. Pointing to 4 pictures should be accomplished by 2.5 years, naming by 3 years and identification by action by 4 years. A neuroscience tutorial focusing on those aspects of the pediatric neurological e
GoNU.TV Interview - Carlos Pena
Former Northeastern baseball player and current Major Leaguer Carlos Pena returned to Friedman Diamond on May 21 to help honor former teammate Greg Montalbano. GoNU.TV spent time talking with Pena in this exclusive interview. Pena and fellow teammates returned to Northeastern for a special number-retirement ceremony for Montalbano, who lost a courageous battle with cancer in 2009. [You can read more about the special Montalbano ceremony here.] Pena, who was in Boston for the Chicago Cubs' fir

Health Across the Life Span: Frameworks,Contexts,and Measurements
Introduces and examines the basic principles which guide growth and development and the health of individuals across the lifespan, from the prenatal period through senescence. Presents methodological, conceptual and substantive issues necessary for understanding and evaluating empirically based information about growth, development and health at different stages of life and from different academic perspectives. Course covers several themes, including contributions of biological and environmental
