PhET is one of my go-to resources for math and science teachers. Just before the Thanksgiving break (for those of us in the United States) PhET released a new simulation designed to help students understand the concept of mean.
Mean: Share and Balance is an interactive simulation in which students are shown a series of beakers of water. They then have to estimate where the mean water level will be. The simulation can be adjusted to show as few as two beakers or as many as seven beakers. When displaying the simulation to your students you can enable or disable level indicators on the beakers and turn on or turn off prediction indicators.
Applications for Education
Mean: Share and Balance could be a great instructional aid for elementary school or middle school lessons. One of the things that’s great about PhET simulations is that most of them, including this new one, can be downloaded for use offline, shared in Google Classroom, or embedded into your website.
