In this work, we study several closely related problems involving chains, conveyor belts, and rockets, which are described and solved without the application of infinitesimal calculus, or even the concept of mathematical limit. On one hand, the novelty lies not in the problems themselves, but in the method used for their solution, which brings…

This review explores the integration and effects of the Internet of Things (IoT) in education, highlighting its importance in transforming traditional teaching and learning techniques. It examines the early uses and historical growth of IoT, its development, and the turning points in its adoption. It explores IoT platforms, tools, and technologies…

A lot of the activities of daily living require energy, playing video games, making dinner, turning on the lights, using a computer, and perhaps even brushing our teeth requires energy. In this unit students discover what energy is, think about where it comes from, analyze options for making energy evaluate feasibility in different parts of the…

This article describes an 8-10 week problem-based learning unit for fifth graders that introduced them to the facts underlying global climate change. This unit was inspired by the lack of awareness in our national population around this clear threat to our global ecosystem and takes on this goal: to provide students (our future advocates and…

This exercise introduces students to the observation that warming is unequal at the level of regions and countries, helps them analyze why this is so, and encourages reflection on actions by specific countries. In addition, students will uncover the relative roles of methane and carbon dioxide in local warming, the role of greenhouse gas emissions…

The present study describes the design of a simple teaching module for each student to fabricate a dye-sensitized solar cell (DSSC) that could power a small fan motor. The significance of this laboratory exercise is to stimulate students' motivation by visualizing the light being converted into electricity, which is then switched over to kinetic…

Emperor penguins, the largest of all the penguin species, attain heights of nearly four feet and weigh up to 99 pounds. Many students are not motivated to learn mathematics when textbook examples contain largely nonexistent contexts or when the math is not used to solve significant problems found in real life. This article's project explores how…

The scientific method is arguably the most reliable way to understand the physical world, yet this aspect of science is rarely addressed in introductory science courses. Students typically learn about the theory in its final, refined form, and seldom experience the experiment-to-theory cycle that goes into producing the theory. One exception to…

Energy exists in many forms and can be converted from one form to another. However, this conversion is not 100% efficient, and energy is lost in the form of heat during conversion. In addition, approximately 6% of the monthly consumption of the average American household's electricity is neither lost nor used by its residents. These losses are…

Using two cardboard boxes, a light bulb socket, light bulbs of varying wattage, a thermometer, and some insulation, students can learn some interesting lessons about how heat loss occurs in homes. This article describes practical experiments that work well on units related to energy, sustainable energy, renewables, engineering, and construction.…

When the term "green" is used to describe a product or way of life, it means "environmentally friendly." Followers of the green movement believe that by reducing their own usage of resources, they can reduce their negative impact on the environment and influence culture to the same ends. The green movement has spread from individuals to companies…

When learning about large-scale environmental problems such as climate change, species extinctions, overpopulation, and habitat destruction, students can become hopelessly dismayed and experience ecophobia--a state of mind in which the student is fearful of the looming environmental problems but senses that there is nothing that can be done to…

In this work we present the design and assessment of a teaching sequence aimed at introducing the principle of energy conservation at post-compulsory secondary school level (16-18 year olds). The proposal is based on the result of research into teaching-learning difficulties and on the analysis of the physics framework. Evidence is shown that this…

Engineers, scientists, and environmental groups around the globe are hard at work finding solutions to mitigate or halt global warming. One major goal of the curriculum described here, Save the Penguins, is to help students recognize that what we do at home can affect how penguins fare in the Southern Hemisphere. In addition, students learn how…

At Montpelier High School (MHS) in Vermont, students are accustomed to making changes in their school and community. Over the last six years, MHS students have participated in the Annual Winooski River Cleanup Project, the construction of a solar-powered greenhouse that provides produce for the school's cafeteria, and a thriving composting program…
