Intelligent Consumption

Submitted by SPH DIGITAL on

Like all living things, humans are "open systems." We're part of - not separate from - our environment, and we continually exchange materials, energy and information with it. What happens when we eat a piece of fruit, for instance? First, we use our senses (taste, smell, sight, touch, hearing) to gather information (Is it ripe?). Then, the fruit's material compounds enter our bodies. As we digest the fruit and break down and absorb its nutrients, energy accumulated from photosynthesis is released. We use this energy to burn carbohydrates through a process called cellular respiration.

Water to Treasure

Submitted by SPH DIGITAL on

"We are mostly water." True or false? Strange as it may seem, it's true! Our bodies are 75 percent water. In fact, some animals such as jellyfish are up to 99 percent water - about the same amount as a human embryo! All living things need at least some water, and all also return water to the environment. We renew ourselves constantly through water; if we didn't, we would die.

Ensuring Healthy Environments

Submitted by SPH DIGITAL on

A healthy environment is made up of many elements that are indispensable for our physical and spiritual health, our cultural wellbeing, and our happiness. Among these are, of course, breatheable air, drinkable water, and enough food to feed the community all of which can become contaminated. A healthy environment also includes factors that we don't often think about.

Learning in Twenty-First Century Schools: Note 6: Norms and Costs of School Infrastructure

Submitted by SPH DIGITAL on

As a general rule, regional educational systems have dissimilar school building patters, with manu dating back to the 19th, or buildings that have responded to various architectural, pedagogical, as well as political currents and that have been adapted more or less successfully to today's requirements. At the same time, investment in recent years has favored the emergence of modern buildings with greater comfort levels, better suited to changes in teaching and learning processes, including the use of technology and computing, accessibility, and community participation.

Learning in Twenty-First Century Schools: Note 5: Environmental Audit and Comfort Levels in Educational Institutions

Submitted by SPH DIGITAL on

The study of comfort levels considers the factors that affect the balance between the body and its environment in buildings in order to ensure that these living spaces -in this case, classrooms- fall within what are referred to as "comfort zones", or in some cases, "life zones". There is a need to provide a suitable design that can provide the parameters and elements with which to generate concrete solutions.

Learning in Twenty-First Century Schools: Note 4: Public-Private Partneships in School Infrastructure in the Caribbean

Submitted by SPH DIGITAL on

Several Caribbean countries are now considering the use of PPPs to modernize their infrastructure and improve the delivery of public services, with Jamaica and Trinidad and Tobago currently providing the most advanced examples in terms of the institutional arrangements that have been put in place (PPIAF 2014). Trinidad and Tobago is currently undertaking preliminary detailed analysis to determine the potential value for money of two pilot projects involving, among other things, the PPP-based procurement of 10 early-childhoods education centers and 10 primary schools.
