...Andrea M.-K. Bierema Students often struggle with the concept of protein synthesis, which incorporates two main processes: transcription and translation. This article describes an activity in which students use craft supplies to physically model the process of translation. The teacher creates the...

...Kwok-chi Lau This article describes an easily made physical lung model for teaching about lung ventilation. It has rectified some major shortcomings of the bell-jar balloon model by having a fluid-filled “pleural cavity,” a dome-shaped “diaphragm,” and an inflated “lung” at rest. The model can be...

...Ladislav Merta; Tomáš Pinkr; Vanda Janštová Molecular biology topics tend to be abstract and hard to visualize, and consequently pupils form many misconceptions about genetics and molecular biology. We describe how to make a hands-on educational set that provides visual and tactile modeling of DNA...

... learning about this topic, it is essential to teach them how to understand and use trees like professional biologists. Unfortunately, few currently used teaching frameworks for evolution instruction are designed for this purpose. In this study we developed the Model of the Use of Evolutionary Trees (MUET...

...Lloyd H. Barrow The purpose of this activity is to provide precollege biology students a visual representation of evolution. Unfortunately, many resources begin with the start of life, which ignores the fact that the Earth is 4.6 billion years old. This model uses adding-machine tape to sequence...

... students learn not only the “what” of science but also the “how” and “why.” In line with this approach, we present an exercise that models the integration of fundamental evolutionary concepts with science practices. Students use Avida-ED digital evolution software to test claims from a study on mutated...

... changing pressure gradients that the valves experience and come to an understanding of valve function. Making your own simple, inexpensive working models allows your students to visualize valve action quickly and easily, and to predict effects on function if valve structure were altered. A link to a video...

...Garrett M. Street; Timothy A. Laubach We provide a 5E structured-inquiry lesson so that students can learn more of the mathematics behind the logistic model of population biology. By using models and mathematics, students understand how population dynamics can be influenced by relatively simple...
