This article discusses the kinematics and dynamics of equestrian show jumping. For some time I have attended a series of show jumping events at Spruce Meadows, an international equestrian center near Calgary, Alberta, often referred to as the "Wimbledon of equestrian jumping." I have always had a desire to write an article such as this…

This article describes the Lissajous generalized figure and the original instrument for its investigation. Two specially prepared electrodynamic loudspeakers--a horizontal and a vertical--cause oscillations in two mirrors. It is possible to precisely control the motion of the mirrors, achieve a high frequency of oscillation and investigate…

Equity Indexed Annuities (EIAs) are controversial financial products because the payoffs to investors are based on formulas that are supposedly too complex for average investors to understand. This brief describes how Monte Carlo simulation can provide insight into the true risk and return of an EIA. This approach can be used as a project…

When high school students are asked what's the best part of science class, many will say it's the field trips. Students enjoy engaging in authentic, community-based science outside the classroom. To capitalize on this, Patrick Willis created the Bird Box Survey Project for his introductory field biology class. The project takes students…

In this guided inquiry, students investigate advantages and disadvantages of genetic engineering by integrating popular fiction into their study of bioethics. What are the effects of artificially created hybrid creatures on characters in "The Hunger Games" and in our society? What are the effects on and basic rights of the organisms…

Scientists and teachers have worked together to produce teaching materials for the Very Small Radio Telescope (VSRT), an easy-to-use, low-cost apparatus that can be used in multiple laboratory experiments in high school and university physics and astronomy classes. In this article, we describe the motivation for the VSRT and several of the…

Of the eight practices of science identified in "A Framework for K-12 Science Education" (NRC 2012), helping students develop and use models has been identified by many as an anchor (Schwarz and Passmore 2012; Windschitl 2012). In instruction, disciplinary core ideas, crosscutting concepts, and scientific practices can be meaningfully…

In this article, the author describes a series of lessons that focuses on observation and documentation of organisms and that is appropriate for the second through fourth grades. By giving students the necessary initial support, they will have the ability to observe details and the skills and confidence to make realistic scientific drawings and…

After months of waiting, the grant reviews came back: "excellent," "excellent," and "fair." What?! How can this be? Why is the third review so out of line with the first two? On more than one occasion a principal investigator (PI) has been frustrated not only by a negative funding decision but more so by the accompanying reviewer evaluation forms…

One of the biggest challenges in the early weeks of the new school year is to keep learning interesting and the students engaged as routines and procedures are established and reinforced. How can a classroom teacher make the routines and procedures engaging and educational, while building a community of learners? The answer is simple... build a…

Having taught K-12 students and preservice teachers for almost 20 years, the author knows the problems that arise when students are asked to generate an investigation of their own design. Therefore, she developed some lessons that significantly increased the diversity and quality of the investigations students generated. This article describes…

This paper describes a simple, rapid and low-cost technique for growing bacteria (or other microbes) in an environmental gradient, in order to determine the tolerance of the microbial population to varying concentrations of sodium chloride ions, and suggests how the evolutionary response of a microbial population to the selection pressure of the…

Finite-state methods are finding ever increasing use among linguists as a way of modeling phonology and morphology and as a method for manipulating and modeling text. This paper describes a suite of very simple finite-state tools written by the author that can be used to investigate this area and that can be used for simple analysis.

The Early Excellence centre was established in 1999 to undertake early years curriculum development in the North West, Yorkshire and Humberside regions. As part of development work, small research projects are commissioned in early years settings. This article describes how the authors worked with Wingate Community Nursery School. The work was…

The alarming number of children killed and seriously injured as a result of child maltreatment and neglect has led to increased calls for action. In response, interdisciplinary and multiagency child death review teams have emerged as an important component of child protection. Paradoxically, child death review teams are among the least visible and…
