Water and an immiscible organic liquid are placed in a small plastic bottle. Ten small pieces of a notecard which is shaded on one side by crayon or pencil (graphite or colored) are cut out and placed inside the bottle. After capping and shaking, the notecard pieces float at the liquid-liquid interface with the shaded side facing the nonpolar…

Science teachers have been urged to use emerging technologies, such as robots, in ways that empower K-12 students as active participants responsible for their learning and knowledge development within the scientific domain. And yet, little is known about whether the use of robots effectively supports students' epistemic agency in science learning.…

As computing becomes an essential component of professional practice across science, technology, engineering, and mathematics (STEM) fields, integration of computing across content areas in K-12 classrooms is also becoming important. Particularly within science classrooms, computer science and computational thinking (CS/CT) are novel and necessary…

Level 3 characteristics are increasingly important for fingerprint identification, particularly when the fingerprints are problematic and lack level 2 details. In practice, no reliable visualization methods for level 3 features are transferred into a course for the general public, forensic students, or investigators. Our group has reported the…

Effective science instruction requires knowledge of subject matter and scientific practices (Next Generation Science Standards (NGSS), 2013), as well as the context within which learning occurs (Anthony, Hunter and Hunter 2014). For science teachers, there is often a tension between the efficiency of lecture and student engagement that comes with…

Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The…

Research has shown that spending time in nature is beneficial for children's mental wellbeing, but how long must they spend to gain some benefit? Here we present the results from two studies: the Schools' Biodiversity Project, which took place over a year, with children spending an hour a week exploring biodiversity in their school grounds; and a…

Students often hold misconceptions about insulation, largely because they put on clothes to keep themselves warm--at least in winter in the cooler regions of Australia. The following activity is designed to identify students' misconceptions about insulation and provide an engaging, evidence-based activity to help address these misconceptions using…

The Yuan T. Lee Foundation Science Education for All (YTLF) has implemented a science camp for students with visual impairments in central Taiwan since 2009. The implementation of the camp serves as an informal science education practice model that informs curriculum design and development, personnel preparation and organization, as well as…

The challenges of contemporary society require pupils to make informed decisions and take responsible actions on problems related to science and technology. This work provides guidelines to support teachers in the design of learning scenarios that enable achievement of these goals. Two classroom examples based on contemporary news events explain…

If you have not yet come across Practical Action's teaching resources, this article will open your eyes to a wealth of free high-quality materials that will support your teaching of science within a real-life global context. The potential benefits and importance of this approach, both for increasing student engagement in science and for the future…

The use of fossils as a tool in the classroom provide the medium in which students enthusiastically and directly engage in scientific exploration and thinking, enhancing their interest in future science curricula, and provide an avenue to develop scientific literacy. The National Research Council stated that students should have authentic…

The purpose of the study was to develop an assessment scale for science activity videos that can be used to determine qualified science activity videos that can fulfill the objectives of activity based science education, help teachers to evaluate any science activity videos and decide whether to include into science learning process. The subjects…

The purpose of this article is to detail the creation of an assignment, after Covid-19 moved our university's instruction online, that helped students make sense of how K-12 teachers were adjusting their own pedagogy. The assignment included two parts: 1) students conducted an interview of their cooperating teacher to understand how they had to…

The vision of Next Generation Science Standards (NGSS) "requires a dramatic departure from approaches to teaching and learning science occurring today in most science classrooms K-12" (Reiser 2013, p. 2). In this article the authors emphasize the importance of examining student misconceptions and correcting them with sense-making…
