Cooler Design Challenge
Read the Fine Print
Educational Use
Rating
0.0 stars

Students learn and apply concepts in thermodynamics and energy—mainly convection, conduction, and radiation— to solve a challenge. This is accomplished by splitting students into teams and having them follow the engineering design process to design and build a small insulated box, with the goal of keeping an ice cube and a Popsicle from melting. Students are given a short traditional lecture to help familiarize them with the basic rules of thermodynamics and an introduction to materials science while they continue to monitor the ice within their team’s box.

This Lesson provides two different activities that require students to measure energy outputs and inputs to determine the efficiency of conversions and simple systems. One of the activities includes Lego motors and accomplishing work. The other investigates energy for heating water. They learn about by products of energy conversions and how to improve upon efficiency. The teacher can choose to use either of these or both of these. The calculations in the water heating experiment are more complicated than in the Lego motor activity. Thus, the heating activity is suitable for older students, only the Lego motor activity suitable for younger students.

Rating
0.0 stars

With increasing public awareness of the multiple effects of global environmental change, the terms water, energy, and food crisis have become widely used in scientific and political debates on sustainable development and environmental policy. Although each of these crises has distinct drivers and consequences, providing sustainable supplies of water, energy, and food are deeply interrelated challenges and require a profound understanding of the political, socioeconomic, and cultural factors that have historically shaped these interrelations at a local and global scale.

This course explores the complex interrelationships among humans and natural environments, focusing on non-western parts of the world in addition to Europe and the United States. It uses environmental conflict to draw attention to competing understandings and uses of "natureâ€ as well as the local, national and transnational power relationships in which environmental interactions are embedded. In addition to utilizing a range of theoretical perspectives, this subject draws upon a series of ethnographic case studies of environmental conflicts in various parts of the world.

Sustainability denotes one of the main future challenges of societies and the global community. Issues of sustainability range from energy and natural resources to biodiversity loss and global climate change. Properly dealing with these issues will be crucial to future societal and economic development. This course provides the theoretical background for the discussion and analysis of sustainability issues. Students will recognize specific sustainability issues, such as sustainable energy, as part of a more complex challenge of developing sustainable societies and systems, and against the background of the general meaning and implications of the conception of sustainability.
