Environmental Science

Learn about the environment with simulations that integrate ecology, geology, biology, and chemistry for an engaging laboratory experience.

FeaturedĚýSimulations for Environmental Science

Cellular Respiration: Measuring Energy Production in Plants , Link will open in a new window

In this simulation, you will understand how cells can convert sugar molecules into usable energy using a process called cellular respiration and compare the volume of oxygen consumed by growing (germinating) soybean seeds and nongerminating soybean seeds in order to estimate the amount of cellular respiration occurring.

Sampling Ecosystem: Biological Sampling , Link will open in a new window

In this simulation, you will collect animals and plants from a defined area in an ecosystem, bring these organisms to the lab to sort and count them, and calculate the Simpson’s biodiversity index.

Osmosis: Movement of Water Across a Selectively Permeable Membrane , Link will open in a new window

In this simulation, you will examine osmosis using thistle tubes that are fitted with membranes over their large, open ends.
