This resource consists of a Java applet and expository text. The applet illustrates Bayesian estimation of the probability of heads for a coin. The prior beta distribution, true probability of heads, and the sample size can be specified. The applet shows the posterior beta distribution.

Watch beta decay occur for a collection of nuclei or for an individual nucleus.

Watch beta decay occur for a collection of nuclei or for an individual nucleus.

This resource consists of a Java applet and expository text. The applet simulates a random sample from a beta distribution, and computes standard point estimates of the left and right parameters. The bias and mean square error are also computed.

Basic overview of the breakdown pathway of bilirubin in the body. Also, a few causes of jaundice including the prehepatic, hepatic and post hepatic causes.

This resource consists of a Java applet and expository text. The applet simulates Bernoulli trials in terms of random points on a timeline. The random variables of interest are the number of successes and the proportion of successes. The number of trials and the probability of success can be varied. This applet illustrates the law of large numbers, the central limit theorem, and the binomial distribution.

This resource is a genetics case study adapted from the National Center for Case Study Teaching in Science for use as a laboratory exercise in an introductory online biology course. It utilizes a fillable form pdf lab answer sheet created by the instructor, Tina B. Jones.

Attributions and references are provided at the end of the laboratory write-up.

Please refer to the "Completing Lab Reports in Canvas Orientation Exercise" in OER Commons also authored by Tina B. Jones for student instructions on downloading, completing, and uploading the fillable form answer sheets in Canvas.

*Lab answer sheet created by instructor using Adobe Acrobat DC Pro.

This is a long-term inquiry activity in which students investigate locations they believe harbor cellulose-digesting microbes, collect samples, isolate them on selective media, and screen them for cellulase activity. These novel microbes may be useful for the production of cellulosic ethanol. In the process they learn about plating techniques, serial dilutions, symbiotic relationships and enzyme specificity. Two methods are provided, one focusing on isolation of pure microbial strains, the other focusing on finding symbiotic communities of microbes. The companion activity is here: https://www.glbrc.org/outreach/educational-materials/bioprospecting-cellulose-degrading-microbes-filter-paper-assay

This site contains user-friendly tools to launch DNA database searches, statistical analyses, and population modeling from a centralized workspace. Educational databases support investigations of an Alu insertion polymorphism on human chromosome 16 and single nucleotide polymorphisms (SNPs) in the human mitochondrial control region.

The aim of this course is to provide fundamental statistical concepts and tools relevant to the practice of summarizing, analyzing, and visualizing data. This course will build your knowledge of the fundamental principles of biostatistical inference. The course will focus on linear regression and generalized linear regression models. We will use a variety of examples and exercises from scientific, medical, and public health research.

This materials have been compiled to support an introductory Biotechnology course for high school students.

An interactive applet and associated web page that provide step-by-step instructions on how to bisect an angle using only a compass and straightedge. The animation can be run either continuously like a video, or single stepped to allow classroom discussion and thought between steps. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.

Cryptocurrencies like Bitcoin rely on blockchain technology and crypto mining, which consume massive amounts of electricity and have significant carbon footprints. The lack of transparency and regulation in the industry raises concerns about the economic, social, and environmental costs associated with crypto mines.

This resource consists of a Java applet and expository text. The applet simulates the bivariate normal distribution. The means are set at 0, but the standard deviations and the correlation can be varied. Simulated points from the distribution are shown as dots in a scatterplot.

This resource consists of a Java applet and expository text. The Java applet illustrates the bivariate uniform distribution on three types of regions: a square, a circle, and a triangle. Simulated points from the distribution are shown as dots in a scatterplot.

The Woodson Center Curriculum provides lesson plans, slide shows, and readings of significant moments in Black American history. Many of the biographies are of Black Americans often ignored by textbooks. The project seeks to highlight examples of excellence, resilience, and perseverance, in the Black community and among Black individuals while battling the realities of racism. 

In this lesson students investigate the effects of black carbon on arctic warming and are introduced to a mechanism of arctic warming that is not directly dependent on greenhouse gases in the atmosphere: black carbon deposition on Arctic snow and ice. It can also be used to introduce the concept of albedo. Prerequisite knowledge: students understand the concepts of absorption and reflection of light energy. This lesson is designed to be used with either an Earth/environmental science or chemistry curriculum. It may also be used as an enrichment activity in physics or physical science during a unit on energy. Includes suggested modifications for students with special needs and low technology option. Requires advance preparation, including freezing ice samples overnight.

This focused resource guide, "Black Lives in Astronomy," includes specific written and video resources about and by 25 black astronomers, as well as general materials to examine the history and issues facing black members of the astronomical community. It includes both older, established scientists and people early in their careers. It is aimed at the Astro 101 and amateur astronomer level, and thus does not include any technical materials. I hope this resource will give instructors and students examples of authentic black voices that can be shown in class or used in assignments.

This lesson plan introduces learners to the historical facts of Black Wall Street and the Tulsa Race Riots of 1921, using primary resources from the Library of Congress.
