Introduction to Minitab
This laboratory introduces students to the basics of the Minitab software. Students make use of a basic example (water consumption and temperature) to introduce students to manipulation of data, calculation of descriptive statistics, and creation of histograms.
Star Library: Which Paper Towel is More Absorbent?
This group activity focuses on conducting an experiment to determine which of two brands of paper towels are more absorbent by measuring the amount of water absorbed. A two-sample t-test can be used to analyze the data, or simple graphics and descriptive statistics can be used as an exploratory analysis. ...
The Kankapot Creek Coast Guard: Public service through water quality monitoring of a stressed stream
The Biology Department at the University of Wisconsin -- Fox Valley is carrying out a long-term project in which students gather water quality data on a nearby impaired stream. These data will eventually be used to help formulate a restoration plan for the stream. This exercise follows the procedures our students use to assess stream habitat quality, chemical and physical parameters, and benthic macroinvertebrate diversity and pollution tolerance. Data collection is completed in the field using
The Use of the Biotic Index as an Indication of Water Quality
This is a field/laboratory exercise involving the collection, identification, and use of aquatic insects to estimate the water quality of lotic stream ecosystems. Aspects of this laboratory are appropriate for an introductory biology course, an extended student project, or a detailed laboratory exercise ...
Using A Molecular Marker to Study Genetic Equilibrium in Drosophila melanogaster
Using Polymerase Chain Reaction (PCR), genetic variation in a laboratory population of Drosophila is characterized. The population contains flies with two variants of a molecular marker. DNA from individual flies is amplified by PCR, generating products which are either "long" or "short" when visualized on an agarose gel. Three PCR "genotypes" (long/long, long/short, and short/short) are distinguishable and should be present in Hardy-Weinberg frequencies. The exercise requires one session for gr
Using Handheld Wireless Computers to Increase Interactivity and Collaborative Learning in Large Clas
We conducted a pilot study to determine the effectiveness of wireless, handheld computers in fostering active and collaborative learning in lecture-based teaching. We compared the capabilities of the largest type of handheld, the Jornada 820, to that of the smallest, a Handspring Visor "personal digital assistant." This article describes our use of the handhelds in a variety of classroom exercises, emphasizing wireless internet access. We explain our successes, problems, and proposed solutions.
Water Transport in Plants: Anatomy and Physiology
This investigation presents a condensation of two, 3-hour laboratory sessions. In one phase, we adopt a classic dye uptake experiment to determine the path of upward water transport in a detached shoot. Photography of stem thin sections taken with a digital video camera aided by compound and stereomicroscopes and a computer significantly enhance the presentation of observations and their interpretation. In a second phase, we determine the quantitative role of leaves in determining the rate of tr
Advance and retreat of the Ice-shelf
Interactive animation showing the changes occurring to an ice-shelf in relation to the temperature of the surrounding water. The animation has been created on the basis of the most recent models created by the modelling team of the antarctic research called ANDRILL.
What Is Water?
This online article is from the Museum's Seminars on Science, a series of distance-learning courses that allow educators to discuss scientific ideas and classroom applications with AMNH scientists and educators. "What Is Water?" is part of The Ocean System course.

Genetically Modified Food: Golden Rice: Help or Hazard?
This online article is from the Museum's Seminars on Science, a series of distance-learning courses designed to help educators meet the new national science standards. Genetically Modified Food: Golden Rice, part of the Genetics, Genomics, Genethics seminar, briefly covers: why more than a million people in developing countries are struck with irreversible blindness; the proposed solution of genetically engineering rice to contain carotenoid, the precursor of Vitamin A; environmental concerns ab
Biodiversity and Human Health: A Guide for Policymakers
Produced by the Center for Biodiversity and Conservation, this guide summarizes the consequences of biodiversity loss for human health. The guide examines threats to global supplies of food and fresh water, exposure to formerly rare diseases and opportunistic infections, and loss of important sources of medicines.
Fish Skull Animation: Jaw Protrusion
This collection of fish-skull animations is from Diversity of Fishes, part of the Museum's Seminars on Science series. These distance-learning courses are designed to help educators meet the new national science standards. The three QuickTime movies take a look at the following aspects of jaw protrusion: how this feeding mechanism allows fish to extend their reach in order to envelope prey; how jaw protrusion increases mouth volume and forces water and prey into the fish's now tube-like jaws; th
