The study of ruthenium polypyridyl complexes can be widely applied across disciplines in the undergraduate curriculum. Ruthenium photochemistry has advanced many fields including dye-sensitized solar cells, photoredox catalysis, lightdriven water oxidation, and biological electron transfer. Equally promising are ruthenium polypyridyl complexes…

Science education research has shown that students use causal reasoning, particularly the model "agent--instrument--object," to explain or predict the outcome of many natural situations. Students' reasoning seems to be based on a small set of few intuitive rules. One of these rules quantitatively correlates the outcome of an experiment…

The famous motto of the Lucky Luke comics series and its accompanying drawing are analyzed from a physicist's viewpoint. They provide useful pedagogical tools to discuss such aspects of relativity as causality, the equivalence principle, gravitational blue shift, and the tachyonic antitelephone. [This article was first published in Hungarian in…

Kinetics is an important part of undergraduate environmental chemistry curricula and relevant laboratory exercises are helpful in assisting students to grasp concepts. Such exercises are also useful in general chemistry courses because students can see relevance to real-world issues. The laboratory exercise described here involves determination of…

Sensory integration dysfunction (SID, also known as sensory processing disorder, SPD) is a condition that exists when a person's multisensory integration fails to process and respond adequately to the demands of the environment. Children with SID (CwSID) are also learners with disabilities with regard to responding adequately to the demands made…

Technology integration has become an ever-present phenomenon in institutions of higher education. This has led to an increase in online learning experiences that make higher education accessible to those who previously experienced barriers, such as having full-time jobs. One issue that affects online education is the challenge of engaging the…

A cordless mouse with an added reed switch is used as a wireless data logger to record every time the wheel of a trolley completes a revolution. The limitations of the system in terms of maximum clicking rate and spatial resolution are considered and data obtained from the descent of a trolley down a ramp at various different angles is analysed in…

The authors argue that there will be a critical mass of women in leadership positions in kinesiology and across higher education for substantial gender-based mentoring to take place in the 21st century. First, the current state of women in higher education leadership, trends in mentoring, and the reasons it is important for women who have…

Some apparently confusing aspects of Newton's laws as applied to an aircraft in normal horizontal flight are neatly resolved by a careful analysis of force, momentum, energy and power. A number of related phenomena are explained at the same time, including the lift and induced drag coefficients, used empirically in the aviation industry.

Defining friction and asking what causes it might seem like a trivial question. Friction seems simple enough to understand. Friction is a force between surfaces that pushes against things that are moving or tending to move, and the rougher the surfaces, the greater the friction. Bill Robertson answers this by saying, "Well, not exactly".…

The experiment described here is fairly easy to reproduce and dramatically shows the magnitude of ambient air pressure. Two circular plates of aluminum are applied one against the other. How do you make their separation very difficult? With only the help of an elastic band! You don't have to use a vacuum pump for this experiment.

The physics of walking is explored, using a toy as a concrete example and a "toy model" applied to it. Besides using Newton's second law, the problem is also discussed from the thermodynamical perspective. Once the steady state (constant velocity) is achieved, we show that the internal energy of the toy is dissipated as heat in the…

Amy Morris Homans was an amazing leader in the early development of physical education. She believed that every individual must be educated academically and physically. Earlier this year, SHAPE America committed to making her vision a reality with the goal of empowering ALL students with the skills, knowledge, habits, and determination to make…

Teaching complex chemistry concepts such as kinetics using inquiry-based learning techniques can be challenging in a high school classroom setting. Access to expensive laboratory equipment such as spectrometers is typically limited and most reaction kinetics experiments have been designed for advanced placement (AP) or first-year undergraduate…

This article presents a rationale for the infusion of social justice into kinesiology programs for the purpose of reducing inequities in society. Specifically, the current climate for social justice is considered and discussed using examples from an university-inspired service-learning initiative, law, and politics. Of note are the following areas…
