This study aimed to investigate ninth grade students' views about enzymes using fortune lines technique and to obtain the students' views about fortune lines technique. Participants were 38 ninth grade students in a Technique Vocational Girls High School in the city of Kocaeli, Turkey. After instruction of subject of enzymes, the participants were…

One author shares the unique opportunity to be immersed in the science of "sound at work" through participation in NOAA's (National Oceanic and Atmospheric Administration) Teacher at Sea Program. A third- through fifth-grade learning outcome within the Nature of Science section of the "Next Generation Science Standards"…

Oxygen is one of the component gases of air at room temperature, making up around 20% of the atmosphere. But can oxygen be liquified? This article details a method for making small amounts of liquid oxygen in the classroom if there is no access to a cylinder of compressed oxygen gas, and two methods for identifying the fact that it is liquid…

In general, laboratories are exercises with a primary focus on the verification of established laws and principles, or on the discovery of objectively knowable facts. In laboratories, students gather data without comprehending the meaning of their actions. The cognitive demand of laboratory tasks is reduced to a minimal level. To prevent these…

In this paper we report on the first year of an online competition in which 480 students took part. After a brief presentation of the organizational structure of the marathon and general data about students' participation, we discuss findings from questionnaires about participants' attitudes towards mathematics, technology, and their perception of…

Since 1996, science education has been guided by the National Science Education Standards (NRC 1996). But now there's a "new sheriff in town" as the "Common Core State Standards" and "A Framework for K-12 Science Education" together become the 21st century's torch bearer for curricula reform in science and…

In the fall of 2011, Park Forest Middle School (PFMS) students approached the STEM faculty with numerous questions regarding the popular television show Myth Busters, which detailed Greek mathematician, physicist, engineer, and inventor, Archimedes. Two episodes featured attempts to test historical accounts that Archimedes developed a death ray…

We developed an educational path based on nitinol, a shape memory alloy which conveniently exemplifies the smart material concept, i.e., a material that performs a predetermined, reversible action in response to a change in the environment. Nitinol recovers a given shape, changes its resistivity drastically and modifies its elastic properties if…

"A Framework for K-12 Science Education" (NRC 2012) recommends that science teachers provide experiences for students to see "how science and engineering pertain to real-world problems and to explore opportunities to apply their scientific knowledge to engineering design problems once this linkage is made" (NRC 2012, p. 32). To…

This project describes a fourth-grade unit that integrated science and language arts using the book "The Capture" as a focal point. During the unit, students engaged in science activities and language arts lessons that focused on owls. Students conducted investigations that helped them develop a deeper understanding of the adaptations of…

Early childhood is a critical period for introducing girls to traditionally masculine fields of science and technology before more extreme gender stereotypes surface in later years. This study looks at the TangibleK Robotics Program in order to determine whether kindergarten boys and girls were equally successful in a series of building and…

The standard for measuring fuel efficiency in the U.S. has been miles per gallon (mpg). However, the Environmental Protection Agency's (EPA) switch in rating fuel efficiency from miles per gallon to gallons per hundred miles with the 2013 model-year cars leads to interesting and relevant mathematics with real-world connections. By modeling…

Afterschool programs are currently conceptualized in two ways. One is represented by "expanded learning," which includes a wide range of content-rich opportunities in the hours outside of school, including summer camps. The operating assumption is that, in structured out-of-school time (OST) programs, children can learn concepts or develop…

A learning module for molecular level analysis of protein structure and ligand/drug interaction through the visualization of X-ray diffraction is presented. Using DeepView as molecular model visualization software, students learn about the general concepts of protein structure. This Biochemistry classroom exercise is designed to be carried out by…

The purpose of this study is to determine whether pre-service teachers have an aim to perform outdoor education activities within the scope of science and technology course; by which factors this aim is affected, through The Theory of Planned Behaviour and the opinions of pre-service teachers. Accordingly, the study was designed as mixed research…
