Elementary GLOBE: We're All Connected
A learning activity for the "All About Earth: Our World on Stage" book in the Elementary GLOBE series. One of the "big ideas" in Earth system science is the notion of interaction among parts of the Earth system. In the Elementary GLOBE book All About Earth: Our World on Stage, the children in Ms. Patel's class discuss instances of how the four major spheres of Earth's system interact. They symbolize these interactions by using large arrows to link the system components: air, water, soil, living

Active Transport in Insect Malpighian Tubules
The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own exper

A Novel Method to Archive Plant Material for DNA Analysis
In this exercise, students isolate and analyze DNA from food plants in a supermarket, or from common backyard plants. Extracting plant DNA is often difficult using conventional means because undesirable material including PCR inhibitors often co-purifies with the DNA. The novel approach used in this exercise is simple and quick, and also avoids the use of dangerous organic reagents. Students crush plant material (spinach leaves in this exercise) onto special cards originally used to archive bloo

Practicing Elaboration in a Problem/Solution Essay
One theory suggests that students tend to list in an essay because they lack the tools to elaborate. Because they do not have the strategies, they attempt to fill up the empty space by introducing new primary ideas instead of fleshing out the ideas they have already presented. This activity attempts to make students aware of the need to elaborate and to provide students with some workable strategies for elaborating. Using a PowerPoint presentation, the teacher demonstrates the necessity for elab

"It Was Considered Low Music": Pianist Eubie Blake on the Birth of Ragtime at the Turn of the Centur
Ragtime music, with its syncopated, polyrhythmic style, was born, according to cultural historian Robert Snyder, in the 1890s in the black saloons and brothels of southern and Midwestern cities like Baltimore and St. Louis. By the end of the 19th century ragtime had assumed a place at the center of American popular music and remained there until the 1920s. Ragtime meant a tinkling piano and no one played the ragtime piano any better or longer than Eubie Blake, born in Baltimore in 1887. In this
