Sensors in Chemistry
The Environmental Protection Agency monitors sensors to track air pollution and set clean air standards. Enthusiastic young scientists use similar sensors to gather data in their area and then apply the gas laws and conservation of...
Howard Hughes Medical Institute
Population Dynamics
Will human population growth always be exponential, or will we find a limiting factor we can't avoid? Young scientists learn about both exponential and logistic growth models in various animal populations. They use case studies to...
