"We Are Literally Slaves": An Early Twentieth-Century Black Nanny Sets the Record Straight
In folklore the black nursemaid was seen as a dutiful, self-sacrificing black woman who loved her white family and its children every bit as much as her own. Yet the popular images of the loyal, contented black nursemaid, or "mammy," were unfortunately far from the reality for the African-American women who worked in these homes. In 1912 the Independent printed this quasi-autobiographical account of servant life, as related by an African-American domestic worker, which dispelled the comforting "
Biological Indicators of Watershed Health
This is an EPA website that gives information on environmental quality. The one icond labeled as compass provides very useful information. It is an environmental atlas that contains U.S. maps and state and regional maps that display air, land and water quality information. For example, information on CO, NO2, ozone, Pb, PM-10 and SO2 are available showing distribution levels of these air pollutants. With a click you can access full reports on air quality in 1996 and 1997. The land a water pa
Types of Antennae
This illustrated guide is designed to help students recognize and learn the different types of antennae found on arthropods. The single Web page, which can be easily printed for use at field sites or in the lab, shows plumose (featherlike) pectinate (comblike) serrate (sawlike) moniliform (beadlike) filiform (threadlike) aristrate (with bristles) elbowed (with a bend) clubbed (the segments towards the end are larger).
This illustrated guide to leaf types is designed to help students understand the differences between compound and simple leaves. This single Web page can be easily printed for use at field sites. Along with an explanation of both types, the guide includes a short description of these related terms: petiole, leaf blade, leaflet, and axillary buds.
This OLogy activity serves as a kid-friendly how-to manual about searching for fossils. In Not Just Any Rock Will Do, kids learn that fossils "hide out" in sedimentary rock and see examples of shale and sandstone. Do's and Don'ts for Fossil Hunters gives kids practical tips and a list of fossil-hunting supplies. In Fossils You May Find, there are photos of common invertebrate, vertebrate, and plant fossils to guide kids. Paleontology Clubs and Web Sites lists resources to help kids determine whe
Observing, Describing, and Identifying Clouds
In this activity students observe and sketch clouds, describing their forms. They initially generate descriptions of a personal nature and then move toward building a more scientific vocabulary. They then correlate their descriptions with the standard classifications using the ten cloud types identified for GLOBE. Each student develops a personal cloud booklet to be used in conjunction with the GLOBE Cloud Chart. . The intended outcome is that students will be able to identify cloud types using
Scaling Galileo's Solar System - Size of the Globes
In this activity students determine the sizes of the various planets in the solar system, scaled such that the orbit of Saturn fits on campus. The students also compare the planet sizes, given the scale, to the grain sizes of different sediment types. Students recreate spreadsheets, shown in a Powerpoint module, with formulas that answer various pieces of the overall question. This module is the second in a series of four on the Galilean Solar System, and was designed for an undergraduate class
This description of a ground-water aquifer has a graphic representation to accompany it. It is part of the U.S. Geologic Survey's Water Science for Schools website. Links to other parts of the site, such as definitions and types of wells, are included.
Automobile Choices and Alternative Fuels
In this lesson students will compare and make distinctions among 5 alternative fuels. They will understand the impact of different types of fuel on: a. the environment b. lifestyle c. the economy/personal finances of car choices. They will also use critical thinking skills to support multi-step decision-making for buying a car.
Data Collection and Organization
The Data Collection and Organization (DC&O) text module provides background on useful, general-purpose software tools. The aim is to discuss types of generic software that virtually every well-equipped scientist uses. This includes: spreadsheets, database programs, statistics packages, graphics programs, and word processors. DC&O includes several examples of the use of these tools in biology. These include 'An Embryological Example with Tips and Tricks' and the complete text and dataset of a cl
Light at the Bottom of the Deep, Dark Ocean?
This Ocean Explorer interactive, hands-on lesson plan (PDF) leads students on an exploration of deepwater adaptations by addressing the focus question: What types of adaptations enable deep-sea fishes to survive and collect food in the darkness of the deep ocean? In the activity, students search for Skittles in a dark room while wearing goggles covered in blue cellophane to simulate deepwater feeding. This lesson plan includes a reproducible student handout and links to reference resources.
Immunology, Winter 2008
General Learning Objectives for Immunology 1. To understand the structural and genetic basis of diversity and specificity of immunoglobulins and T cell receptors. 2. To understand the utility of antibodies in many clinical tests for proteins, hormones, etc. 3. To understand the events that hallmark the antigen-independent and antigen-dependent phases of B cell differentiation. 4. To understand the diversity of MHC molecules, and how that diversity differs from immunoglobulin and T cell rece
World History Survey Course on the Web
World History teachers face many challenges to incorporating primary sources in their teaching—the pressures of coverage in survey courses, the lack of available materials, and inadequate training in dealing with unfamiliar sources from a range of cultures. World History Sources responds to these challenges (as well as the new opportunities offered by the Internet) by creating a website to help world history teachers and students locate, analyze, and learn from online primary sources and to fu
The Advanced Light Source (ALS) is a particle accelerator that moves electrons in a big way to produce extremely bright light for many types of scientific experiments. The ALS moves the electrons using electromagnets (in the linear accelerator, booster ring, and storage ring) and permanent magnets (in the undulators and wigglers). This unit gives students the chance to move electrons and explore the relationship between electricity and magnetism by making a simple electromagnet and building the
