This study aims to examine students' reasoning based on the model in each laboratory work style and find the effect on scientific attitude and student activity. This study uses a quantitative approach with the experimental method. The study was conducted in three classes with different lab work styles. Arduino and sensors were used as a…

In this article, second graders learn the basics of engineering through an exploration of magnetic levitation (maglev) technology. The author designed and taught the lessons to a class of 26 students enrolled in a month-long summer science program. The maglev lessons took place over three mornings (15 minutes for the first lesson and 40 minutes…

This paper describes three methods of measuring the coefficient of restitution (CoR) for two different types of ball-on-ball collision. The first collision type (for which two different CoR measurement procedures are described) is a static, hanging steel ball forming part of a Newton's cradle arrangement, which is then hit by its adjacent…

Matter is an essential science topic that is often challenging to teach at the early elementary levels. Learning about matter helps students develop a solid foundation for more complex concepts that are taught in later years. Make this abstract concept developmentally appropriate for children by engaging them in investigations that focus on…

The use of creativity in science practices is many times lost on secondary students. Creativity is seen as something central to the arts and humanities, but tangential at best in the sciences. However, an examination of many great scientific discoveries and the work of everyday contemporary scientists shows the depth and breadth of the use of…

We describe a set of conceptual and hands-on activities based around understanding the dynamics of a Slinky that is hung vertically and released from rest. This Slinky drop experiment typically lasts a fraction of a second, but when observed in slow motion, one sees the Slinky compress from the top down while the bottom portion remains at…

Recently, there have been many calls for an increase in instruction on the nature of science (NOS) in schools (i.e. NRC, 1996; NGSS Lead States, 2013). These calls recognize the importance of this topic at all levels of science education, but there is little guidance in terms of how to address it effectively in curricula. Similarly, there have…

We describe an activity that is suitable for high school students and makes use of plastic bottles. This activity allows students to familiarize themselves with gas chemistry by introducing technologies that were applied in old submarine systems. Plastic bottles, which are representative of submarines, are used as reaction vessels. Three simple…

During the Jurassic period (201 million to 145 million years ago), termites up to 15 mm long consumed and recycled vegetation and feces. Since then, termites have evolved into some 3,000 identified species, have colonized every continent except Antarctica, and are major contributors to nutrient cycling and vertebrate food webs (Shaw 2014).…

The American Association for the Advancement of Science (AAAS) strongly recommends that "science be taught as science is practiced." This means that the teaching approach must be consistent with the nature of scientific inquiry. In this article, the authors describe how they added scientific inquiry to a large lecture-based physiology…

There are many lab exercises for upper-level school students and freshman undergraduates to measure the value of the local acceleration due to gravity ("g") near Earth's surface. In these exercises, the value of "g" is usually taken to be constant. The approach is often based on measuring the period of a pendulum that is…

The concepts of protein purification are often taught in undergraduate biology and biochemistry lectures and reinforced during laboratory exercises; however, very few reported activities allow students to directly gain experience using modern protein purification instruments, such as Fast Protein Liquid Chromatography (FPLC). This laboratory…

The Einstein-First project approaches the teaching of Einsteinian physics through the use of physical models and analogies. This paper presents an approach to the teaching of quantum physics which begins by emphasising the particle-nature of light through the use of toy projectiles to represent photons. This allows key concepts including the…

The aim of the study was to examine parents' and their children's experiences of science experimentation in terms of parents' roles, science process skills assessed during the experiment and academic successes regarding science lessons. Realization of science activities by students and their parents is at the centre of this study. That is why its…

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…
