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…

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…

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…

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…

We describe an investigative laboratory module designed to give college undergraduates strong practical and theoretical experience with recombinant DNA methods within 3 weeks. After deducing restriction enzyme maps for two different plasmids, students ligate the plasmids together in the same reaction, transform "E. coli" with this mixture of…

Describes a program that attempts to bridge the gap between class lectures and laboratory. Students are involved in individual investigations. Effective use of undergraduates is made for instructional purposes. (PS)
