Homeostasis is a core concept necessary for understanding the many regulatory mechanisms in physiology. Claude Bernard originally proposed the concept of the constancy of the "milieu interieur," but his discussion was rather abstract. Walter Cannon introduced the term "homeostasis" and expanded Bernard's notion of…

In this article the authors describe what they call their "Snapshots of Science" program. These mini-lessons of science are taught once a week to all students in the school library. Over the last two years, they have been working to extend the experiences students have in their science classroom into the library. Each week, students…

Earth and space science deserve the same level of inclusion in early childhood curriculum as the other science disciplines, and research shows that the sooner children are introduced to concepts like those presented in planetarium programs, the stronger their lifelong interest in science will be. Much astronomy visualization outside of…

The periodic table does more than provide information about the elements. The periodic table also helps us make predictions about how the elements behave. Understanding the atomic structure of matter and periodic properties of the elements, as shown in the periodic table, is fundamental to many scientific disciplines. Unfortunately, high school…

Three gold-nanoparticle (AuNP) undergraduate experiment modules that are focused on nanoparticles interfacial phenomena have been developed. Modules 1 and 2 explore the synthesis and characterization of AuNPs of different sizes but with the same total gold mass. These experiments enable students to determine how particle size affects the AuNP…

Thermal science is challenging for students due to its largely imperceptible nature. Handheld infrared cameras offer a pedagogical opportunity for students to see otherwise invisible thermal phenomena. In the present study, a class of upper secondary technology students (N = 30) partook in four IR-camera laboratory activities, designed around the…

High school students often enter classrooms with misconceptions about density. While many students may have studied the concept in middle school, they lack the understanding on which to build more advanced concepts, such as the particulate nature of matter. This lack of understanding poses problems for students' learning about Pascal's principle…

In the fall of 2008, Stacy McCormack's students were caught up in the presidential election, and she began to wonder how she might harness this passion for politics in her high school physics classroom. At about the same time, a friend recommended the book "Physics for Future Presidents" (Muller 2008), which led her to develop a year…

"Evolution" is an area of the curriculum in which children show great interest and enthusiasm to learn more. They also bring considerable prior (though incomplete) knowledge from their informal "life worlds". Most children have encountered the term "evolution" from an early age and tend to define it in terms of…

When the author took on the role of primary science advisory teacher at Centre for Industry Education Collaboration (CIEC) she thought it would be a really interesting role that would give her room to develop her skills as a teacher, but she had not appreciated just how powerful the links to industry can be for children. One example of how such an…

"Mythbusters: The Explosive Exhibition" is a traveling exhibit based on the popular television show. When housed at the Museum of Science and Industry, Chicago, it included a traditional, interactive free flow exhibition space followed by a live facilitated show. This paper describes results from an experimental study about the effects…

General chemistry is the first undergraduate course in which students further develop their understanding of fundamental chemical concepts. Many of these fundamental topics highlight the numerous conceptual interconnections present in chemistry. However, many students possess incoherent knowledge structures regarding these topics. Therefore,…

Although students do need hands-on experiences to master key skills in science, technology, and engineering, Cummins asserts, K-12 teachers should also help students understand key STEM concepts by reading, writing, and talking about the work of professional scientists and engineers. Cummins lists high-quality texts that help young people…

A method to determine the temperature dependence of copper wire resistance is described in this paper.

In an era when many students carry iPods, iPhones, and iPads, physics teachers are realizing that in order to continue to inspire and convey the amazing things made possible by a few fundamental principles, they must expand laboratory coverage of electricity and circuits beyond the conventional staples of constructing series and parallel…
