Among the new educational tools and new ways of teaching/learning of the last 20 years, educational approaches based on constructivism are of great interest because they offer the possibility for students to build scientific concepts from experimental observations. Cooking is truly a universal topic--it can be considered a true multidisciplinary…

It is important that students understand the role the ocean plays in mitigating climate change, and how every person on this planet is uniquely connected to the ocean. Identifying these connections can be challenging for students in rural or underserved areas, many of whom do not live by, or interact with, the ocean. Through the use of the board…

STEM is a well-known acronym describing the intersections of science, technology, engineering, and math. Emerging from this paradigm is a relatively new interdisciplinary model entitled STEAM. STEAM endeavors to intersperse "the arts" into the sciences with the expectation of increasing student engagement and skills within the sciences.…

Science teachers' beliefs about teaching and learning are a vital component of teachers' professional competence and are often assumed to impact classroom practice. To date, these beliefs have been predominantly investigated regarding teaching and learning in general or for a particular science subject (e.g., physics). It remains to be determined…

Practical work is a distinctive feature of school science and has close associations with scientific experiment and scientific methods as well. In this study, the nature of practical work was examined in the view of the diversity of scientific methods. Based on an analytical framework derived from Brandon's matrix consisting of four categories of…

The California Blackworm ("Lumbriculus variegatus") is a freshwater segmented worm species that has been used by biology instructors as a model system for inquiry-based student investigations. The blackworm dorsal blood vessel pulsation rate is easily quantified. Moreover, this species can facilitate the study of neuromuscular…

This work documents the collaboration between the Physics department of the University of Calabria and some schools of the region in a project devoted to recovering disused instrumentation in school laboratories. The project has been conceived as a workplace experience for the students, i.e. a learning experience in a real work place. In Italy,…

In order to introduce students to the fascinating field of femtochemistry, we propose here a practical laboratory training course conceived for second-year master's students in chemistry. We describe the use of a broadband femtosecond transient absorption (pump-probe) experiment for monitoring a fast light-triggered chemical reaction in solution.…

The instructors of four biology-related courses at a Canadian university integrated Labster virtual labs in their courses as a pre-lab activity, lecture substitute, or to provide lab experience in courses with no on-site labs. The instructors used a backward design approach to align the labs with the learning objectives of their courses and to…

Each fall at harvest time, young students in the authors' part of the Midwest visit apple orchards to learn more about the life cycle of plants. This tradition is one part of a larger unit centered on apples, integrating life science with language arts and social studies. The authors partnered with kindergarten teachers at several schools to…

In this study, the spring constant was determined within the scope of Hooke's law. For this purpose, an Arduino MEGA, an HC-SR04 Ultrasonic Distance Sensor, and a 1 kg Load Cell Mass Sensor was used. Sensors and microprocessor are mounted on a plane. One end of the spring is mounted on the force sensor, and a wooden rod, perceived by the distance…

In science courses in general, but especially in first year chemistry classes, the amount of content that is delivered is often overwhelming and too complex for the student to easily cope with. Students not only have to gain knowledge in a variety of different fields, they also have to learn new laboratory skills and analytical techniques.…

Germinating a seed is presumably the first experiment made by a child in his life. So, it has an important place both in child's scientific experience and understanding. Despite the significance of the experiment, the literature indicates that students possess various misconceptions related to the concepts of seed and seed germination. So, it is…

In this work we discuss the intricacies of a simulation using the MS Excel spreadsheet that allows to study in detail the process of heat transfer between two reservoirs at different temperatures through a conducting rod when heat losses are neglected. The proposed physical model computes the time dependence of the reservoir temperatures and…

In this article we present simple and low-cost experiments about the polarization of light. We use an LCD monitor or an RGB LED light bulb with a Polaroid as a source of polarized radiation, a polarizer sheet as an analyzer, and a smartphone camera to measure light intensities. Thus, using a digital camera to acquire videos students can explore in…
