Students are well aware of the effect of the deflection of sports balls when they have been given a spin. A volleyball, tennis, or table tennis ball served with topspin results in an additional downward force that makes the ball difficult to catch and return. In soccer, the effect of sidespin causes the ball to curve unexpectedly sideways,…

Since physics is often a service course for college students, it is important to incorporate everyday examples in the curriculum that inspire students of diverse backgrounds and interests. In this regard, baseball has been a workhorse for the physics classroom for a long time, taking the form of demonstrations and example problems. In this…

When carbonated beverages (which are supersaturated solutions of aqueous carbon dioxide) are confined within a narrow-necked container, events which rapidly release the gas from solution produce a fountain out of the beverage. One well-known variant of this experiment is the addition of Mentos candies to a bottle of Diet Coke. Previous reports…

This study describes a new module design for teaching research skills to analytical chemists based on the use of a student-led, in-class experiment involving coffee. The module was redesigned in response to feedback from students, and aims to give them the skills they need to be productive in future research projects both within the institution…

This study investigates how the acceleration and speed of a light-emitting object on an inclined plane may be determined using a smartphone's light sensor. A light-emitting object was released from the top of an inclined plane and its illuminance values were detected by a smartphone's light sensor during its subsequent motion down the plane. Using…

This math activity focuses on experimental design while connecting math with life science. It is important that the science and engineering practices (SEPs) are not taught as a separate "unit" but integrated within the curriculum wherever possible. The focus is on experimental design to teach animal behavior. Students predict and test…

Science, Technology, Engineering, and Math (STEM) have developed broad prevalence in the American (U.S.) education system over the last decade. Academic, government, and business experts emphasize that attracting K-12-university students to STEM subject matter is crucial for expanding the innovation capacity of the U.S. and preparing citizens for…

The Chemical Engineering Department at the University of Granada have endeavored to make a number of high quality experiments to familiarize our students with our latest research and also scale-up of processes. A pilot-scale wastewater treatment plant was set-up to give students a close practical view of the treatments of effluents by-produced in…

In high-school teaching of mechanics, we deal, among other things, with the nature of static and kinetic friction, forces that are proportional to the normal force. Under the influence of frictional forces, a body moves down a rough sloped decline at a fixed rate of acceleration that is independent of its mass. This situation does not apply to…

The purpose of the experiment presented in this paper is to quantify the viscosity of a liquid. Viscous effects are important in the flow of fluids in pipes, in the bloodstream, in the lubrication of engine parts, and in many other situations. In the present paper, the authors explore the oscillations of a physical pendulum in the form of a long…

Students make and test a seemingly impossible material made from ice and sawdust that had been developed for possible emergency use during the Second World War. It was open to the students to be creative with their methods of testing the viability of such a material. The thought of making a battleship from ice that would gradually melt seems…

The transition from A-level to degree-level practical classes then to a research project, hence from dependent learner to independent researcher, is a hurdle that all students face when studying for a chemistry degree. This can be daunting so any innovations that aid this transition are of great value. At the University of Reading, the first year…

Although research and new technologies have introduced different ways of observing microorganisms, including scanning and electron microscopy, these methods are expensive and require equipment that is typically not found in a middle school classroom. The transmission-through-dye technique (TTD; Gregg et al., 2010), a new optical microscopy method…

As well-developed as they may be, standards are not curriculum. It is the job of teachers and curriculum teams to use the Standards as the basis for designing the specific pathway for teaching and learning. In this article, the authors explore the use of Understanding by Design (UbD), a widely-used curriculum development framework, for honoring…

This research explored dream science classrooms of primary school third and fourth-grade students. Research is designed as a case study. The students were first asked to illustrate their dream science classroom and produce a short description of their drawings. Second, they were asked to write their expectations of their teachers, their…
