COULD YOU LIVE WITHOUT POTABLE WATER? READ THIS SCOOP MAGAZINE AND TELL ME

Mª Inmaculada's insight:

Understanding all of the different ways that water can cause problems in a society can be a big challenge. The simple jigsaw activity and quiz are based off of the 4 effects components on our website (health, hunger, poverty and education). They are easy to understand but should still give students a glimpse into the complexity of the situation

To learn about the effects of the water crisis, we suggest utilizing a jigsaw approach. Have students get in groups of 4; this group will be their 'home group'. Assign each student one web-page to read to themselves: Health, Hunger, Poverty, and Education (links listed below).

After reading the material, students will form an 'expert group' where they will meet with the students from the other 'home groups' who have read on their same topic. They will discuss with their 'expert group' and determine how best to teach their 'home groups' about their subject. After meeting with their topic groups, students should return to their 'home groups' to teach the other students about their particular sections.

A simple half-page quiz is included to ensure that students have actually communicated the critical information to their 'home groups.' In the jigsaw method, the quiz should not be graded but simply be used as a check to ensure that students communicated overall ideas, not necessarily specifics. You may choose to use the quiz page as both a pre- and post- test or cut the quiz page in half to only have students complete the quiz after the jigsaw experience.

In addition to the jigsaw, you may choose to ask students to:

Create a public service announcement video using at least 1 fact from each effect. If you send us the YouTube link, we may even repost it!Craft a 30 second news intro summarizing the effects of bad water. (Have your school's TV station use it before broadcasting the PSA!)Host a debate arguing which effect has the greatest impact - or have students write position papers.Write a story about a family that experiences the effects of dirty water and predict how their life might be different after a well or other project is built.

A Self-Filling Water Bottle

A Self-Filling Water Bottle | the problem of water in the world | Scoop.it
EcoGeek - Technology for the Environment

 

 

The need for water is important in many parts of the world without the infrastructure to provide safe drinking water. There are many personal technologies that can be used water purification or water gathering. While the idea of a self-filling water bottle may at first sound like magic, it's based on nanotechnology and biomimicry.

NBD Nano is named for the Namib Desert Beetle, whose shell functions to collect water for the insect, and which served as the inspiration for the technology. The technique behind this uses hydrophilic (water retaining) and hydrophobic (water repelling) coatings to concentrate moisture in the air onto the hydrophilic surfaces, and then, as the droplets become big enough, the water runs into a central collector. A small fan is used to move air over the surface to improve collection.

The company is pursuing a variety of possible applications for the technique. While it is not yet a commercial product, this offers a possibility of making water scarcity less of a problem in an increasingly water-dependent world.
