Environmental Science

Show Students How To Investigate Their World

From soil studies to wind energy, environmental science teaches students how to interact with the natural world. Our easy-to-use sensors support educators as they help their students understand key concepts using data-collection technology. Our lab books provide educators with ready-to-go investigations to help students establish a deep understanding of key scientific concepts.

We are scientists, educators, and your team

We’re here to support you as an educator as you implement data-collection technology into your teaching. See how our products provide you with affordable classroom, laboratory, and field-based solutions designed for student success.

The Effect of Acid Deposition on Aquatic Ecosystems

Acid deposition is a topic of much concern in today’s world. It can kill fish and other water life by lowering the pH of lakes and rivers. The pH scale is a measure of acidity. A pH value of 7 is neutral, values lower than 7 are increasingly acidic, and values higher than 7 are increasingly basic. Acid deposition is more harmful in some areas than others because some water resists changes in pH better than others. This ability to resist pH change is called buffering capacity.

Fossil Fuels

Hydrocarbons are compounds containing only hydrogen and carbon atoms. Many common fuels such as gasoline, diesel fuel, heating oil, aviation fuel, and natural gas are essentially mixtures of hydrocarbons. Paraffin wax, used to make many candles, is a mixture of hydrocarbons with the representative formula C25H52.

Ethyl alcohol, a substituted hydrocarbon with the formula C2H5OH, is used as a gasoline additive (gasohol) and as a gasoline substitute.

Investigating Dissolved Oxygen

Dissolved oxygen is one of the primary indicators of the quality of an aquatic environment. Oxygen enters water from the surrounding air, as a product of photosynthesis, and as a result of rapid movement of water. A Dissolved Oxygen Probe can be used in a wide variety of tests or experiments to determine dissolved oxygen concentrations (DO) and changes in dissolved oxygen concentrations.
