The beta hemoglobin protein is identical in humans and chimpanzees. In this tutorial, students see that even though the proteins are identical, the genes that code for them are not. There are many more differences in the introns than in the exons, which indicates that coding regions of DNA are ...

Students commonly test the effects of chemical agents on the heart rate of the crustacean Daphnia magna, but the procedure has never been optimized. We determined the effects of three concentrations of ethanol, nicotine, and caffeine and of a control solution on heart rate in Daphnia. Ethanol at 5% and ...

Urban students often have limited access to field sites for ecological studies. Ubiquitous ants and their mounds can be used to study and test ecology-based questions. We describe how soil collected from ant mounds can be used to investigate how biotic factors (ants) can affect abiotic factors in the soil ...

The techniques of forensic anthropology and pathology can provide new information to increase student interest in studying the structural details of the human skeleton. We present a simplified methodology for assessing skeletal ethnicity, sex, age, and stature. An inexpensive method has been devised for constructing an osteometric board to allow ...

During laboratory sessions devoted to ecology, 182 preservice K-8 teachers participated in a Project Wildlife in Learning Design (WILD) workshop. Participants rated the workshop highly, indicated they would use more inquiry-based activities, and were more interested in teaching ecology following the workshop. Post-test scores indicated an increased content knowledge of ...

Describing the progression of insects that arrive at a cadaver can be a useful and exciting tool for teaching students about complex concepts such as ecological succession.
De Squza-Hart, Janet - - 2010
A "blog" can be used as an online journal club to supplement classroom learning. When crafted in a certain way, it can help students develop their scientific reading comprehension, critical thinking, and writing skills in a way that can easily be assessed by educators.
Shipley, Gwendolyn - - 2010
Instead of dissecting animals, students create small clay models of human internal organs to demonstrate their understanding of the positioning and interlocking shapes of the organs. Not only is this approach more environmentally friendly, it also forces them to learn human anatomy--which is more relevant to them than the anatomy ...

Many statistics texts pose inferential statistical problems in a disjointed way. By using a simple five-step procedure as a template for statistical inference problems, the student can solve problems in an organized fashion. The problem and its solution will thus be a stand-by-itself organic whole and a single unit of ...
Rop, Charles - - 2010
This is a set of animal behavior investigations in which students will practice scientific inquiry as they observe crayfish, ask questions, and discuss territoriality, social interactions, and other behaviors. In doing this, they hone their skills of observation, learn to record and analyze data, control for variables, write hypotheses, make ...

Natural selection and other components of evolutionary theory are known to be particularly challenging concepts for students to understand. To help illustrate these concepts, we developed a simulation model of microevolutionary processes. The model features all the components of Hardy-Weinberg theory, with population size, selection, gene flow, nonrandom mating, and ...

A survey of Florida teachers reveals many differences in comfort level with teaching evolution according to the state's science teaching standards, general attitudes and beliefs about evolution, and the extent to which teachers are criticized, censured, disparaged, or reprehended for their beliefs about the teaching of evolution.
Love, Alan - - 2010
An overlooked feature of Darwin's work is his use of "imaginary illustrations" to show that natural selection is competent to produce adaptive, evolutionary change. When set in the context of Darwin's methodology, these thought experiments provide a novel way to teach natural selection and the nature of science.
Harley, Suzanne - - 2010
Charles Darwin's botanical studies provide a way to expose students to his work that followed the publication of On the Origin of Species. We can use stories from his plant investigations to illustrate hey concepts in the life sciences and model how questions are asked and answered in science.
Senter, Phil - - 2010
Mainstream scientists often claim that australopithecines such as the specimen nicknamed "Lucy" exhibit anatomy intermediate between that of apes and that of humans and use this as evidence that humans evolved from australopithecines, which evolved from apes. On the other hand, creationists reject evolution and claim that australopithecines are "just ...

In a flexible multisession laboratory, students investigate concepts of phylogenetic analysis at both the molecular and the morphological level. Students finish by conducting their own analysis on a collection of skeletons representing the major phyla of vertebrates, a collection of primate skulls, or a collection of hominid skulls.
Curtis, Anthony - - 2010
I describe three activities that allow students to explore the ideas of evolution, natural selection, extinction, mass extinction, and rates of evolutionary change by engaging a simple model using paper, pens, chalk, and a chalkboard. As a culminating activity that supports expository writing in the sciences, the students write an ...
Beachly, William - - 2010
I describe a quantitative approach to three case studies in evolution that can be used to challenge college freshmen to explore the power of natural selection and ask questions that foster a deeper understanding of its operation and relevance. Hemochromatosis, the peppered moth, and hominid cranial capacity are investigated with ...

This article describes how to use protein extraction, quantification, and analysis in the undergraduate teaching laboratory to engage students in inquiry-based, discovery-driven learning. Detailed instructions for obtaining proteins from animal tissues, using BCA assay to quantify the proteins, and data analysis are provided. The experimental procedure requires laboratory equipment and ...

This article provides both an experiment and a framework for discussion that students can use to compare the efficiency of producing ethanol by using corn versus sugarcane as a raw material.

Authentic assessment exercises are similar to real-world tasks that would be expected by a professional. An authentic assessment in combination with an inquiry-based learning activity enhances students' learning and rehearses them for their future roles, whether as scientists or as informed citizens. Over a period of 2 years, we experimented ...

The national Science, Technology, Engineering, and Math (STEM) Education Initiative favors a curriculum shift from the compartmentalization of math and science classes into discrete subject areas to an integrated, multidisciplinary experience. Many states are currently implementing programs in high schools that provide greater integration of math, sciences, and technology. Program ...

It is certainly widely appreciated that there is much to be gained in the fertile crosstalk between science and history--whether bringing a historical perspective into the science classroom (Wieder, 2006) or a scientific perspective to the study of history (McElvaine, 2002; Smail, 2008). Perhaps the major impetus for using history ...

We propose an experimental model suitable for demonstrating allele frequency change in Drosophila melanogaster populations caused by selection against an easily scorable conditional lethal, namely recessive flightless alleles such as apterous and vestigial. Homozygotes for these alleles are excluded from reproduction because the food source used to establish each generation ...

Optimal diet selection, a component of optimal foraging theory, suggests that animals should select a diet that either maximizes energy or nutrient consumption per unit time or minimizes the foraging time needed to attain required energy or nutrients. In this exercise, students simulate the behavior of foragers that either show ...
