Modeling Population
Ecology 
Use the interactive activity to learn about Ecology and model populations of African Lions in Tanzania.
World Biomes
This interactive module explores biomes, climate, biodiversity, and human impacts around the globe and at different times.
Weather and the Environment
Ecology 
Weather Lab is a tool to help visualize how North America’s weather is formed. Each prediction you make is for possible outcomes during Spring.

Cellular Respiration
How does the number of seeds in the chamber affect the rate of respiration? This simulation allows you to change three different variables: type of seeds, number of seeds, and temperature. When you start the experiment, you can alter the variables and it will run for two hours.
Cellular Respiration II
This simulation can be used as a virtual lab for photosynthesis, cellular respiration, and primary productivity. Oxygen levels are monitored in an aquatic environment to measure oxygen production and consumption as part of energy conversion processes.
Simple Blood Typing
Blood pressure is the pressure of circulating blood on the walls of blood vessels. Most of this pressure is due to work done by the heart by pumping blood through the circulatory system. Find the average systolic and diastolic pressure for the group. You may use the calculator at the bottom of the virtual laboratory.
The Blood Typing Game
Biology 
What happens if you get a blood transfusion with the wrong blood type? Try to save some patients' lives and learn about human blood types! (To receive the wrong blood type is life-threatening.
Cell Cycles
Biology 
In this investigation, you will explore the similarities and differences between the cell cycle of normal cells and cancer cells.
