Earth System Science (Lab 1): Think Globally, Act Locally

Students are introduced to four major components of the Earth system: the atmosphere, hydrosphere, biosphere, and pedosphere. They start to apply this knowledge as they visit the local study site to identify elements of these four spheres and infer connections among them. The investigation concludes with students making predictions about ways that a change in the characteristics of one component of their study site might affect the characteristics of other components.

Construction of the Cell Membrane

Students will be able to study the structure of the cell membrane by constructing it using the correct molecules. Through building the molecular structure of the cell membrane, the student will learn the makeup and the basis for cell membrane function, as well as identify and locate the membrane porteins of a cell wall.

Heredity Mix n Match

Students randomly select jelly beans (or other candy) that represent genes for several human traits such as tongue-rolling ability and eye color. Then, working in pairs (preferably of mixed gender), students randomly choose new pairs of jelly beans from those corresponding to their own genotypes. The new pairs are placed on toothpicks to represent the chromosomes of the couple's offspring. Finally, students compare genotypes and phenotypes of parents and offspring for all the "couples" in the class. In particular, they look to see if there are cases where parents and offspring share the exact same genotype and/or phenotype, and consider how the results would differ if they repeated the simulation using more than four traits.

Meteorological Monsters

Students will study the pattern of hurricanes using data from the 2005 huricane season. The U.S. Weather Service has been documenting tropical cyclones in the Atlantic Ocean for over 150 years. The hurricane season of 2005 broke several records, making it the most extreme season since record keeping began: 2005 had the most hurricanes in one season (15), the most category 5 hurricanes (4), the most intense Atlantic hurricane ever recorded (Wilma), and the first recorded European landfall of an Atlantic cyclone (Vince).

The Botany of Desire

In The Botany of Desire, Michael Pollan explores risks inherent in one of the most widespread practices in modern agriculture. It's called monoculture, and it refers to cultivation of single or very similar varieties of a food crop on large acreages. In many cases, the variety is one that dominates the marketplace, like the Russet Burbank potato, whose shape makes it a favorite for cutting French fries, or one of the few apple varieties commonly seen in supermarkets. Monoculture may offer economic advantages, but Pollan argues that it brings serious environmental risks.

Inside the Brain: An Interactive Tour

The human brain is in many ways a fantastic and enigmatic part of the body, and only within the past few decades have scientists begun to understand its many nooks and crannies. When the brain is beset with any number of neurological conditions, it changes in a myriad of ways. This website, provided by the Alzheimer's Association, provides an interactive tour of the brain of a person with Alzheimer's disease. The tour contains sixteen interactive slides, and each slide contains informative text that provides background material. The first seven slides contain a bit of background information about the brain, such as what the brain is composed of and how it functions.

How do cancer cells behave differently from healthy ones?

This video lesson is on the details of cancer cell growth. How do cancer cells grow? How does chemotherapy fight cancer (and cause negative side effects)? The answers lie in cell division. George Zaidan explains how rapid cell division is cancer’s "strength" -- and also its weakness.

Reactions in Chemistry

Reactions in Chemistry is an eight-part workshop for the professional development of high school chemistry and physical science teachers. The workshop blends chemistry content, history, and technological applications with a range of classroom lessons to provide teachers with updated knowledge and new approaches to pedagogy. Teachers will see diverse classes doing hands-on lessons and labs and will hear teachers reflect on their own practices. The on-camera teachers meet in roundtable discussions about teaching strategies and the particular challenges of helping students connect the content to their own lives. The programs also present the work of industrial and forensic chemists and researchers.
