An astronomy "experiment" composed of three parts is described in the article. Being given necessary data a simple model of inner planets of the solar system is made in the first part with planets' circular orbits using appropriate scale. In the second part revolution of the figurines used as model representations of the planets along…

This paper presents a meta-analysis of the literature on parental engagement with children's formal and informal science, technology, engineering and mathematics (STEM) education. Five recurrent themes have emerged from the literature review: The challenges of supporting parents with children's STEM education; STEM education as a bridge between…

Inquiry-based approaches to science education are central to recent South African primary and secondary school curricula, but have been found challenging to adopt in disadvantaged township contexts. It is therefore important to find ways of introducing inquiry-based approaches, where pupils are encouraged to investigate phenomena they are…

The Next Generation Science Standards (NGSS) and other national frameworks are calling for much more sophisticated approaches to STEM education, centered around the integration of complex experimentation (including real labs, not just simulations), data collection and analysis, modeling, and data-driven argumentation, i.e., students can behave…

Cruise planning may seem like an ordinary task for oceanographers, but it actually involves logical and strategic thinking, collaboration, and multidisciplinary work. The "Challenger" expedition, led by Charles Wyville Thomson from 1872 to 1876, was the first to be fully dedicated to understanding oceans (Rice et al. 1999) and was…

Elementary teachers often avoid the struggle of matching a science activity to a specific standard by using a lesson planning process known as Understanding by Design (UBD) (Wiggins and McTighe 2005). A main tenet of the UBD model involves starting at the end rather than at the beginning of the planning process. By starting at the end and visiting…

Teachers have an important role in raising environmental awareness in individuals through environmental education and thus preventing environmental problems. For this reason, the self-efficacy level of teachers in environmental education is crucial. This study aims at determining the self-efficacy levels of geography and biology teachers and…

Science education is changing. With the release of the Next Generation Science Standards [NGSS], K-12 teachers are expected to engage students in the practices of scientists and engineers to make sense of disciplinary core ideas and crosscutting concepts (NGSS Lead States, 2013). Simultaneously, there is a push to expose students to Science,…

During the preschool years children develop many new skills, including gross motor abilities, which serve as a foundation for school readiness skills in areas such as language, socialization and cognition. Like other domains, motor skill development does not happen without practice opportunities. That is, it requires multiple opportunities whereby…

Among the fields that particularly lack images of diverse participants are those of science, technology, engineering, and math, fields captured under the acronym STEM. Often in STEM fields, images and experiences of deaf and hard of hearing children, children of color, and young women are rare or absent altogether, with the result that these…

This article presents a qualitative study, descriptive-interpretive in profile, of the effectiveness in learning about the nature of science (NOS) of an activity relating to the historical controversy between Pasteur and Liebig on fermentation. The activity was implemented during a course for pre-service secondary science teachers (PSSTs)…

Chemistry lesson should be supported with experiments to understand the lecture effectively. For safety laboratory environment and to prevent laboratory accidents; chemical substances' properties, working principles for chemical substances' usage should be learnt. Aim of the present study was to analyze the effect of experiments which depend on…

Despite Singapore's excellent science achievements in international benchmark tests such as the Trends in International Mathematics and Science Study (TIMSS) and Programme for International Student Assessment (PISA), little is known about Singaporean children's (aged 4-8) emerging science conceptions as formal science schooling begins at Grade 3…

Topical science is about developing an awareness of science issues in the news and the importance of science stories that affect pupils' lives and the world around them. It is about making science relevant for pupils and engaging them in the subject. The author explores how children can be engaged and inspired through topical science. The idea of…

A laboratory experiment is described that extracts the tetrapyrrolic teal-colored biliverdin IXa, as its dimethyl ester, from commercially available emu eggshells. The extraction of ~10 mg samples of biliverdin is simple and requires two 3 h lab periods: A two-step acid digestion and liquid-liquid extraction, followed by short silica gel flash…
