This simulation comes from an amazing site called The Concord Consortium. In this simulation, the user will observe and gather data on a population of rabbits as the evironment suddenly changes. Each rabbit has type have unqiue traits and adaptations. As time goes by, you can analyze the population by viewing the line graphs automatically generated from the simulation. This is great for learning about natural selection and fitness.

Sound Waves

This simulator is all about pitch and frequency. It's very simple, but it has the potential to be a great engagement resource. The controls are easy. You simply slide the bars to create high and low frequencies and listen to the pitch. There is also a visual model of the wave you create so students can see how frequency is changed by wavelength.

NOVA - Energy Lab

You are in charge of the energy deparment of your city. You are given three different proposals from a committe to meet the growing energy demans for the future. You have to determine how much renewable and nonrenewable energy resources you will rely upon and the cost effectiveness. In this interactive lesson, the user learns all about the challenges of creating a sustainable energy grid.

Factors that Affect Air Quality

mrscherb — 2024-07-01 22:06:05 UTC

This simulation provides an experience of controlling air quality in an isolated location. The user can make changes to variables of weather as well as human factors, such as emissions. As you run tests, the air quality index displays on a line graph in real time. This would be a great supplemental resource or engagement tool. It's easy to use and reset.
