This article introduces a flexible and easy-to-implement open-ended scientific inquiry activity called the Paper Towels Challenge. After experimentally determining which of three unbranded paper towels is the most absorbent, students discuss their results and methods. The teacher facilitates the discussion of epistemological issues. This activity…

An approach to online laboratory exercises for analytical chemistry students with demonstrated practical exercises through the use of remote-controlled gas chromatography (GC) instrumentation is discussed. The approach allows for a practical-based learning activity to be carried out by students who are unable to attend in-person laboratory…

Chromatography is the most common analytical technique able to identify and quantify a wide gamut of substances in food, environmental, forensic, pharmaceutical, and many other kinds of real samples. We propose a simple drama science activity: students embody different compounds wearing emblems of different colors and dramatize their…

Children can see the Moon with the naked eye and often are curious about the Moon and other objects in the sky, like the Sun and the stars. However, there is sometimes disagreement in early childhood about whether studying space is appropriate for young children. This activities described in this article engaged children who had different learning…

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…

Boasting a wide range of interactive and engaging features, narrative-based learning has become increasingly popular in educational settings. Narrative-based instructional approaches engage students in a novel set of engaging experiences for educational purposes. Although it is not a new concept, the implications of narrative-based learning for…

This article illustrates several types of at-home science experiences that could be incorporated during grades K-2 to provide enriching science experiences that are motivating for students without requiring exhaustive work and preparation. These activities are designed to augment science interest and enthusiasm of students in the classroom and…

Before students learn Kirchhoff's rules, they are typically taught how to solve "combined series-parallel" circuits. The method presented in many textbooks begins by drawing a series of simplified circuits, replacing series and/or parallel elements with their equivalent resistances, eventually reducing the circuit to a voltage source and…

School science is often very different from "real world" science. One important difference, and possibly the main one, is that in school science the relationships between variables have often been sanitized -- essentially "cleaned up" -- so that there is very little (and often no) variation in the data from the relationship…

In an effort to increase student comprehension and retention of basic chemistry concepts within a college level general chemistry course, a series of activities were created. These activities are referred to here as integrated problems. They were developed to help students by continuously reviewing key concepts and incorporating new material into…

Visualizations are useful tools for helping students to understand chemistry concepts at the particulate level. A classroom activity was developed based on learning theory and evidence-based practices, combining protein visualization with thermodynamic parameters from differential scanning fluorimetry (DSF) data analysis. Coding of student…

Students completing undergraduate majors in chemistry are not typically required to undergo formal training in computer programming or coding. As a result, many chemistry students are graduating without skills in understanding, writing, or manipulating computer code. This skills gap places students at a disadvantage, considering the widespread and…

The topic 'Animals including humans' runs through the primary science National Curriculum in England (DfE, 2013). Ideally, topics such as inheritance will lead onto adaptation, natural selection and evolution across key stages 1 to 2 (ages 5-11). This article provides nine engaging activities to support the teaching of adaptation and improve…

At any point during the school year, a teacher may find out the gap between what students know and need to learn is not large at all. In fact, formative assessment data may show a handful of students already have mastered the content for a specific unit of study. While some learners will achieve grade-level standards at the pace outline by a…

Where does our food come from? Such a question may be difficult for some children to answer, especially those living in a city apartment devoid of a backyard with a vegie patch or fruit trees. This article describes a learning experience designed to encourage Year 1 children to think about the foods that humans obtain from plants. The learning…
