The activity proposed in this study aims to investigate the equilibrium between the liquid and vapor phases in a mixture of water and acetic acid, both of which are volatile substances. High school students can easily determine the composition of the liquid phase and its corresponding vapor phase at equilibrium using a simple and conceptually…

The climate emergency is a source of anxiety for many young people. Images of drought, heat waves, wildfires, storms and flooding are increasingly appearing in the media. Today's children stand to be the recipients of our legacy of climate change, while not feeling empowered to do anything about it, so perhaps it is no wonder they are anxious.…

Catalysis is an essential concept in chemistry, playing a key role in industrial processes. Catalysis has been considered to be challenging not only for university students to comprehend but also for the teachers. In this Laboratory Experiment, we have described a simple activity for demonstrating the concept of catalysis using thread-based…

Stimulating interest in science at an early age is important for STEM education. This work details an educational activity utilizing the anthocyanins found in butterfly pea flowers ("Clitoria ternatea"). This activity was developed for use in official classroom settings, online, and/or at-home with parental or educator guidance. Primary…

Cyclic voltammetry (CV) is the most popular electrochemical technique for the study of electrode processes. One of the reasons for its popularity is its adjustable timescale which can vary several orders of magnitude simply by varying the rate at which the potential is scanned. Changing the scan rate affects CV features including the current,…

Herein we propose the implementation of an "escape room" activity to reinforce chemistry-related concepts for students of the Bachelor of Arts and Fashion. In this work, a combined online and offline activity is developed, easily adaptable to different environments. The online activity consists of 5 blocks of multiple-quiz questions…

Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Water is a special substance. Not only do humans rely on water for survival, but it is also fascinating to play with and makes a great topic to investigate. Many simple investigations can be done with water, at home or at school, to guide children's science learning. This article describes a sequence of online learning experiences that were set…

It is generally agreed that making real-world connections in mathematics teaching increases students' motivation and interest and contributes to meaningful and permanent learning. In this paper we propose a simple and fast activity to find a rectangular hyperbola in real life and we show how to operate the data to retrieve a straight line. Since…

Since the COVID-19 pandemic, there has been an increase in healthcare and related science majors at the undergraduate level. This presents an opportunity to introduce health science training in middle school science classes to familiarize students to various healthcare-related fields. The pharmaceutical science-based hands-on activities for middle…

Science is the study of the world around us, and a scientist's job is to ask questions about the world and then experiment to find the answers. There is not a more natural scientist than the Elementary child, whose reasoning mind is eager to ask questions, investigate, and discuss and compare findings with their peers. In this article, the authors…

With biochemistry forced to transition to remote-teaching online, the cooperative active learning and problem-solving normally in labs have been limited. With little ability to perform experiments with laboratory equipment, determining how to mimic the qualities integral to these labs in an online environment is necessary. We propose one possible…

The "Next Generation Science Standards" ("NGSS") have placed an emphasis on the incorporation of engineering practices into K-12 science instruction. This article details a sequence of physical science lessons that would be part of teaching matter in the second-grade classroom. The goals of these lessons are: (1) to be hands-on…

Science instruction is a critical aspect of early learning. Teachers can support young children's learning about scientific concepts through the use of the Universal Design for Learning (UDL) framework, which is a proactive approach to instructional planning that helps ensure success for all learners. This teaching techniques article offers…

This paper presents exemplification of the ways in which teachers can incorporate the ideology of maker education into STEAM club activities. The intention is to showcase how science teachers can infuse making into their pedagogy and inject more creativity into the learning process, yet still link it to existing science curricula, more…
