Research into seed germination classroom activities has been common in the last few decades. Didactic proposals have generally focused on the implementation of guided activities in a specific educational stage and context, and an evaluation of the results. However, it is not evident that students approach seed and germination concepts with a…

A collection of four activities for science outreach events was developed to teach middle school students about the temperature dependence of scientific phenomena. Procedures are described for four interactive demonstrations on phase changes, fluorescence, viscosity effects on diffusion, and conductivity. Each hands-on activity helps students…

This study explored the impact of interactive e-books on the viewing behaviors of children in science demonstrations at museums. To conduct this study, an interactive e-book on a pendulum experiment was developed and integrated into a physical science demonstration at a museum. Two scientific demonstrations were conducted in this study. The first…

Purpose: The aim of this research is to determine the impact of hands-on science activities on preschool children's motivation for science. Design/Approach/Methods: The study group of the research, in which the quasi-experimental design with pretest-posttest control group was used, consists of 25 children aged 60-72 months who are continuing their…

By hosting a college students' laboratory skills contest, we provide an interesting activity for students to cultivate good laboratory practices and thereby improve their laboratory skills. The substance of this contest is the detection of the hardness of water, which involves numerous laboratory skills such as solution preparation, weight by…

During the August 21, 2017, solar eclipse, high school students measured secondary cosmic ray flux using QuarkNet detectors. These students conducted experiments examining cosmic ray flux, shower, speed of muons, and muon lifetime using QuarkNet cosmic ray muon detectors (CRMDs). These detectors measure muon flux of momenta greater than ~2 GeV, a…

Understanding experimental design (e.g. control of variable strategy or CVS) is foundational for scientific reasoning. Previous research has demonstrated that demonstrations with cognitive conflict (e.g. asking students to evaluate and explain different experimental designs) are effective in promoting children's scientific reasoning, however, the…

This study revamps and optimizes the teaching and learning process and instrument for the classic binary vapor-liquid equilibrium experiment by combining activity coefficient model simulations and practical exercises. Our teaching process combines a software simulation and practical exercises. Utilizing Aspen software, students can predict phase…

Einstein's derivation of special relativity theory (SRT), based on hypothetical reasoning and thought experiments, is regarded as a prime example of physics theory development. In secondary education, the introduction of SRT could provide a great opportunity for students to engage in physics theorizing, but this opportunity is largely being missed…

This paper presents the case for how students can be helped to increase their scientific vocation by experimental work and the introduction of particle physics into pre-university studies. These two ideas are the two main lines of work of the ADMIRA initiative, which has been created by individuals belonging to different and complementary…

Fungi mostly reproduce through spores that are adapted for airborne dispersal; hence, fungal spores (and fungi) are found virtually everywhere. Fungi can be "friends or foes." Our friends include fungi used in the food and biotech industries, fungi that contribute to the cycling of carbon and nutrients, and those involved in the…

This study aims to draw attention to data literacy, which is considered an important skill of the 21st century, and to provide an example activity that would incorporate it into chemistry education. The activity was designed using real data of Robert Boyle's experiment. The activity aims to examine Boyle's data in such a way to support data…

Students were tasked with the creation of videos of ordinary reactions to promote significant learning of complex concepts underlying chemical transformations. Interactive infographics were used to deliver instructions. Afterward, students planned the experimental setup for the reaction execution and video recording using their mobile phones. The…

This qualitative study aimed to explore what are pre-service elementary teachers' (N = 325) conceptualizations of scientific practices prior to their entry into the science teaching methods course through their drawn images and narratives of the scientists (male and female) and teacher as scientists. Data (drawings, narratives, and responses to…

Developing students' critical thinking skills is often seen as an important educational goal for inquiry assignments. In this study, we investigated to what extent pre-laboratory activities of a chemical inquiry assignment influence students' independent critical thinking. We compared two forms of pre-laboratory activities that are frequently used…
