For the past dozen years, the University of North Carolina (UNC) at Chapel Hill has been developing a unique, survey-level astronomy curriculum, primarily for undergraduate students, with the goal of significantly boosting STEM enrollments on a national scale, as well as boosting students' technical and research skills. Called "Our Place In…

Laboratory automation and data science are valuable new skills for all chemists, but most pedagogical activities involving automation to date have focused on upper-level coursework. Herein, we describe a combined computational and experimental lab suitable for a first-year undergraduate general chemistry course, in which these topics are…

Basic science courses, such as physics, are fundamental to precollege studies. For instance, in different engineering applications, electricity and magnetism require comprehending subjects such as electrical circuits and power electronics. However, abstract concepts such as electric or magnetic fields are often difficult to explain without visual…

The author introduces the Passive Dynamic Walker robot, which is constructed with LEGOs and operates without any electronics. Building this robot offers an excellent platform for investigating center of mass and other important physics and engineering concepts.

A mechanical model of light propagation helps to show that optical refraction is related to the speed of light and how it changes from one medium to another. A tricycle toy robot is used to realize the model. Left and right wheels independently change their speed (high or low) in response to the local color (white or black, respectively) of the…

Space exploration is intrinsically interesting to young learners. Children gaze at the stars and marvel at what it might be like to live "out there!" With the July 2020 launch of the Mars 2020 Perseverance Rover mission, and its landing in 2021, there is no better time to capitalize on engineering and science in the news. This mission is…

This work describes a way to study uniform circular motion (UCM) using a LEGO® MINDSTORMS® Robotics Invention System (RIS) stepper motor with a steel ball attached to a string. The equipment is inexpensive and the resulting motion takes place on a human scale. Times and lengths can be measured with a stopwatch and a meterstick, respectively. In…

Electricity is an integral part of daily life. Children, like adults, infer the effects of electrical conductivity. They see the illumination of a lightbulb or feel the emission of warmth from an electric stovetop but may not understand the role electrical circuits play. Focusing on the concrete aspects of electrical energy transfer helps improve…

Fused filament fabrication 3D printing is a process by which three-dimensional objects are created by depositing layers of a material onto a hard, flat surface by a robot. It is often referred to as an "additive manufacturing" technique because material is added in successive layers to create an object. Because many scientific…

In this paper, we aim to show strategies for improving graph interpretation skills at middle and high school students using OZOBOT® BIT, a small and relatively low-cost programmable robot which had been used to teach programming to young children. OZOBOT's speed can be controlled by drawing lines with colour codes, as well as through a visual…

Experimental teaching is essential for a good understanding of science, especially on Physics. Practical activities play an important role for engaging students with science, mainly when they interact directly with equipment, collect experimental data with computers and/or use interactive software for data analysis. In this work, we present the…

This article describes an early childhood lesson that integrated science, technology, art, social studies, math, and language. The authors' students compared robots, programmed and created stories with robots, and became robot-inventors. They also imagined how their robot-creations might impact the world--a core idea related to Science, Technology…

Using innovative technologies to study Mars and the sun and other stars is one way to engage learners in learning more about our solar system and how it impacts us on a daily basis. The focus of this paper is to highlight several innovative technologies such as augmented reality and virtual reality that are easily accessible by educators and…

Science communication is increasing through the use of Unmanned Aerial Systems (UAS) or drones. Within the Arthur Temple College of Forestry and Agriculture at Stephen F. Austin State University (SFASU), UASs such as the DJI Phantom 4 Pro and Mavic Mini2 drones were used by students and faculty to study mistletoe, crepemyrtle and fire ants and…

In an ever-increasing technological society, teachers have now, more than ever, a vast offering of educational technologies made available for classroom use. However, the time necessary for vetting and developing rigorous lessons with the usage of such technologies can be overwhelming for a classroom teacher. Still, teachers need the opportunity…
