"Catalase," an enzyme found in both plant and animal cells, prevents the accumulation of toxic levels of hydrogen peroxide (H[subscript 2]O[subscript 2]) by catalyzing its decomposition to water and oxygen gas. Because this enzyme is ubiquitous, it is frequently used in high school biology laboratories to explore enzyme reactions. This…

When I was a freshman at Tokyo University of Science, my senpai (upper-class student mentor) took me to a certain skiing ground in his car, which was equipped with standard tires. He tried to enter the parking area there, but his car could not climb a short slope leading to the entrance. I would like to describe here how he dealt with the problem…

An activity is described in which students in the first semester of a two semester organic chemistry laboratory class are introduced to the use of SciFinder. Students are required to determine the structures of three compounds as well as additional information regarding the synthesis of one of them using some of the features available in SciFinder.

The effects of the mouthpiece and bell on the frequencies of the vibrating air column in a trombone can be demonstrated quite readily by first calculating the expected resonant frequencies of a piece of PVC pipe that is the same length as a trombone, then replacing portions of the PVC pipe of the same length with first a cup-shaped mouthpiece and…

This paper describes the formation of a circumzenithal arc for the purpose of teaching light and optics. A circumzenithal arc, an optic formation rarely witnessed by people, is formed in this study using a water-filled cylindrical glass illuminated by sunlight. Sunlight refracted at the top and side surfaces of the glass of water is dispersed into…

The paper deals with innovative teaching methods at universities. The result of this effort is the interactive P&E method, whose main idea is the interactive work with students while solving problem tasks. The main aim of the given method is to change the students' position, by means of experiment analyses and qualitative tasks, from a passive…

Engaging children's interest, inspiring active exploration of materials, and fostering cooperation between children and adults is the best way to promote the construction of knowledge. Some popular early childhood activities can be expanded to provide experiences and time for children to build on their prior knowledge. This column discusses…

Young students need opportunities to develop their conceptual understanding of properties of matter. By providing students with inquiry activities, we lay the groundwork necessary for students to grasp the challenging concepts associated with learning about the periodic table in middle school. In this 5E activity (Bybee 2009), fifth-grade students…

The lichen is an ideal subject for student study because it is omnipresent in school yards, easily collected and observed year-round, a pioneer of evolution on land, and a bioindicator of air pollution. After doing fieldwork on this unusual composite organism as an apprentice with a team of lichenologists, Sarah Thorne developed Learning Lichens.…

Because honeybees are so crucial to the ecosystems in which they exist, educating younger children on the usefulness and relative harmlessness of honeybees may be key to ensuring their survival among future generations. Described here is a unit that addresses the critical role of the honeybee in pollinating flowers using the 5E learning cycle…

Objectives: Among the 14 indicators identified in Monitoring Progress, this paper focuses on: the adequacy of instructional time (Indicator 2) and opportunities (Indicator 3) for science learning in grades K-5. This paper considers these two indicators together since they form the basis for opportunities to learn science in elementary school.…

Social communication deficits associated with Autism Spectrum Disorder are often exacerbated during adolescence. Group based approaches are effective intervention techniques for facilitating improved social communication skills in people with ASD; however, science, technology, engineering, and math activities, while highly preferred areas of…

This paper examines the differences and challenges encountered when trying to create informal blended (virtual and hands-on) engineering design STEM activities. It contrasts the creation of STEM activities for formal and informal learning environments, stressing that the differences extend far beyond the length of the activity or depth of any…

In this article, we turn our attention to context-based approaches to science instruction. We studied the effects of changes to a set of secondary science teacher education programs, all of which were redesigned with attention to the Secondary Science Teaching with English Language and Literacy Acquisition (SSTELLA) instructional framework, a…

Studies have consistently documented that introductory geoscience students struggle with visualizing features presented on topographic maps. This is a problem that has the potential to increase in a digital age when engagement with maps consists primarily of GPS navigation via smartphones. Since the first augmented reality (AR) sandbox in 2012,…
