In recent years, the integration of technology into education has significantly transformed teaching methods, especially in science education. Tools like PhET simulations have proven highly effective in enhancing student engagement and comprehension. Research has highlighted the value of simulation-based learning in fostering critical thinking and problem-solving skills. This study aimed to explore the impact of simulations, with a focus on PhET, on improving elementary students’ learning outcomes, an area that remains under-researched. The study compared the performance of two groups of third-grade students: one group learned about solubility using PhET simulations, while the other relied on traditional textbook instruction. Each group comprised fifty students. The study lasted for a two-month period. The instructional approach was investigative learning. Data were gathered through student responses to materials science questions aligned with Bloom’s Taxonomy, allowing for a detailed evaluation of their understanding and application of scientific concepts. Responses were assessed for accuracy and scored accordingly. We ran an independent-sample t-test to decide whether the difference in the mean score in science achievement between the two research groups was significant. The results showed that students using PhET simulations not only achieved significantly higher scores but also demonstrated their ability to explain their reasoning during problem-solving tasks. These findings emphasize the substantial advantages of incorporating digital tools like PhET simulations into elementary science education, as they enhance conceptual understanding and better equip students to tackle future scientific challenges. The present research results complement the previous research on using technology in the chemistry elementary classroom and add the issue of simulations to this research. The results of this study are centered on the topic of solubility. To broaden the generalizability of these findings, future research should examine the effects of simulations on student achievement in a wider range of elementary science topics.

This research delved into the integration of PhET simulations in elementary science education, specifically aimed at Grade 3 students. The primary objective was to evaluate how the use of these digital simulations influenced students’ conceiving of scientific concepts, focusing on “States of M1atter and Phase Changes” and “Solubility and Saturation”. Employing a qualitative research approach, the study observed 19 students who worked in pairs and trios as they engaged with PhET simulations to explore assigned science topics and address related questions. The observations centered on tracking students’ interactions with simulations and their progression through different knowledge phases. We used deductive and inductive content analysis to analyze the transcripts of the observation. The findings reveal that in the “Remembering” phase, students demonstrated a tendency to relate personal experiences to simulations, underscoring real-life context’s role in learning. The “Understanding” phase highlighted how PhET simulations facilitated deeper comprehension, with students making insightful observations. Additionally, the “Application” phase showcased the effective translation of simulation-derived knowledge into practical scenarios, bridging theoretical and real-world understanding. Students’ use of high-order thinking skills, at the analysis, evaluation, and creative phases, showed that simulations supported Grade 3 students in their learning processes of scientific concepts. The research underscores the efficacy of integrating PhET simulations into elementary science education, enhancing students’ knowledge by promoting active engagement and problem-solving skills. Integrating simulations into teaching methodologies emerges as a promising avenue to nurture scientific expertise and holistic understanding among elementary school students.

Background: The goals of the current study were to address a new concept termed a health benefits’ index (HBI) and to verify the type of correlation between the pricing of honey and its HBI/medicinal properties. Diverse types of honey from different origins and places were investigated for their antioxidant and antimicrobial activity. Methods: We have utilized a modified protocol of the DPPH assay for measuring free radical scavenging and the microdilution test for the determination of antibacterial/antifungal minimum inhibitory concentrations (MICs). MICs were determined against Staphylococcus aureus, Escherichia coli, Salmonella typhimurium, and Candida albicans microorganisms. Employing a “combined benefits approach” enabled us to attach to each honey type a unique number of HBI that correlate with honey health and medicinal values. Results: The various types of honey demonstrated significant but variable antioxidant, antibacterial, and antifungal activities. Types of wildflower-labeled honey were found to have a wide range of HBI values and medicinal properties, probably due to their containing different nectar contents/phytochemicals. Moreover, an inconsiderable correlation was detected between the market prices of different types of honey and their HBIs. Conclusions: The proposed index of health benefits could be recalculated/updated following measurement of more and more medicinal properties, such as anti-inflammatory, antidiabetic, and anticancer activities. This index could be used as an effective tool for consumers of honey to evaluate the real value of the purchased product.
