Join the Global Chemistry Experiment "Water: A Chemical Solution"
2011 is the International Year of Chemistry (IYC 2011). It is a global celebration of the achievements of chemistry and its contributions to the well-being of humankind. Teachers and students from around the world are invited to explore one of Earth's most vital resources, water. Through the Global Chemistry Experiment ‘Water: A Chemical Solution’ students will explore the chemistry of water and the role of water in society and the environment. The results of their investigations will contribute to a Global Experiment, which will possibly become the biggest chemistry experiment ever.
The Global Water Experiment consists of four component activities:
1. pH of the Planet: Students collect data measuring the pH of water using indicator solutions.
2. Salty Waters: Students explore the salinity of their local water.
3. Solar Still Challenge: Students will construct a solar still from household materials and experiment with its use to purify water.
4. Water: No Dirt, No Germs: Students will learn how chemistry is used to help provide safe drinking water.
Each downloadable activity includes a teacher’s guide, a list of necessary material for carrying out the activities and explicit instructions on how to carry out the activities in class.
On the 22nd September, specialists from NASA and the American Chemical Society will discuss this experiment and how water filtration affects our lives on Earth and in space. Check out the webcast at http://dln.nasa.gov/.
