Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

The addition of the arts to STEM education, now known as STEAM, adds a new dimension to problem-solving within those fields, offering students tools such as imagination and resourcefulness to incorporate into their designs. However, the shift from STEM to STEAM has changed what it means for students to learn within and across these disciplines.…

With just a few materials, building a paper model of the International Space Station (ISS) can become an excellent group, troop, or class project. This publication contains a brief overview of the ISS, its parts, the science that occurs on board, instructions, and extensions for an interdisciplinary technology experience. Discover more about the…

The collision model is frequently introduced to describe electronic conductivity in solids. Depending on the chosen approach, the introduction of the collision time can lead to erroneous results for the average velocity of the electrons, which enters the expression for the electrical conductivity. In other textbooks, correct results are obtained…

An educational model simulation of the sound produced by lightning in the sky has been employed to demonstrate realistic signatures of thunder and its connection to the particular structure of the lightning channel. Algorithms used in the past have been revisited and implemented, making use of current computer techniques. The basic properties of…

Educating About Social Issues in the 20th and 21st Centuries: A Critical Annotated Bibliography, is comprised of critical essays accompanied by annotated bibliographies on a host of programs, models, strategies and concerns vis-a-vis teaching and learning about social issues facing society. The primary goal of the book is to provide undergraduate…

The creative application of low-cost, readily available materials and techniques promotes inclusion and provides accessibility in the classroom and laboratory for students who are blind or have low vision. Difficulties encountered by these students include operation of laboratory equipment, execution of ordinary laboratory procedures, and use of…

Science classes are full of abstract or challenging concepts that are easier to understand if an analogy is used to illustrate the points. Effective analogies motivate students, clarify students' thinking, help students overcome misconceptions, and give students ways to visualize abstract concepts. When they are used appropriately, analogies can…

Shocked by static? Mixed up about magnets? Curious about currents? Teachers can get past memorizing all those electricity-related formulas, rules, and procedures so they can understand the subject at a level deep enough to teach it with confidence and comfort. Here to help is "Electricity and Magnetism," the fifth title in the award-winning NSTA…

This study investigated prospective secondary science teachers' understandings of and intentions to teach about scientific modelling in the context of a model-based instructional module. Qualitative methods were used to explore the influence of instruction using dynamic computer modelling. Participants included 14 secondary science prospective…

Nine years after the National Science Education Standards' release, just how well do science teachers in grades 5 to 8 actually use them to plan content, define improved teaching, and assess real learning? Find out the answers to these key questions in this groundbreaking collection of 15 essays by teachers, researchers, and professors whose…

This book presents information, activities, and paper models related to aviation. Most of the models and activities included use a one page, single concept format. All models and activities are designed to reinforce, clarify, or expand on a concept, easily and quickly. A list of National Aeronautics and Space Administration (NASA) Center education…

Describes how to make the following paper molecular models: trigonal prism; tetragonal pyramid; tetrahedral; and trigonal pyramid. Methodology is given for general paper model manipulation to make various shapes including a chain of tetrahedra and an icosahedron. (MVL)
