This lesson provides an introduction to the treatment of drinking water to remove harmful or distasteful substances. Topics include the history of treatment and a brief listing of treatment processes.
Greenhouse Effect, Climate Change, Global Warming
The terms greenhouse effect, climate change, and global warming are often used interchangeably, yet they really refer to three separate and distinct processes. This activity examines all three and assesses whether Earth's atmosphere is getting warmer.
Due to the presence of dissolved gases such as carbon dioxide, rainfall is naturally acidic. This exercise will familiarize you with the phenomenon known as acid rain, requires that you take water samples from rainfall.
Drinking water treatment 2
This course deals with the design of drinking water treatment plants. We discuss theory and design exercises.

NASA KSNN What do plants need to grow?
By definition, a plant is a living thing that produces its own food through photosynthesis. This process uses carbon dioxide and water. Trapping light from the Sun, plants are able to change sunlight's energy into useable chemical energy. Not only is chemical energy produced, but oxygen is a by-product of photosynthesis. Plants are essential to the balance of life on Earth - and to life, as we know it, on other planets.
NASA KSNN What is an invention?
Inventing is fun and exciting and everyone can be an inventor. An inventor is someone who thinks of new ways to solve problems in the home, community, or even the world. These solutions are called inventions. An invention may be a new product or a new way of doing things. Inventions come about in many ways. Most of the time, inventions happen because someone works to solve a problem.
On the Road Again
The movement of people and goods is an important part of the New York State Global History and Geography Curriculum. It is listed as one of the themes that are emphasized in the core curriculum.

Density and Pressure
What makes a block of wood rise to the surface of a bucket of water? Why do your ears “pop” if you swim deep underwater? In this session, we will examine density, an essential property of matter. We will also look at how particles of matter are in constant motion, leading to a deeper understanding of fluid pressure. Finally, we will investigate the concepts of pressure an
Global energy use increases by the day. Polluting the atmosphere with ever more carbon dioxide is not a viable solution for our future energy needs. Can new technologies such as carbon sequestration and ethanol production help provide the energy we need without pushing the concentrations of CO2 to dangerous levels?
Looking Forward: Our Global Environment
Earth's essential systems are being stressed in many ways. There are many tipping points in the environment, beyond which there could be serious consequences. Will human ingenuity, resiliency, and cooperation save us from the worst outcomes of our global experiment?
Chemistry and the Environment
