TED-Ed: How Do Hard Drives Work?
The modern hard drive is an object that can likely hold more information than your local library. But how does it store so much information in such a small space? Kanawat Senanan details the generations of engineers, material scientists, and quantum physicists who influenced the creation of this incredibly powerful and precise tool.
TED-Ed: How Statistics Can Be Misleading
Statistics are persuasive. So much so that people, organizations, and whole countries base some of their most important decisions on organized data. But any set of statistics might have something lurking inside it that can turn the results completely upside down. Mark Liddell investigates Simpson’s paradox.
PhET: Projectile Data Lab
The Projectile Data Lab simulation allows students to engage in hands-on data collection and analysis through the context of projectile motion.
PhET: Curve Fitting
Drag data points and their error bars and watch the best-fit polynomial curve update instantly. You choose the type of fit: linear, quadratic, or cubic. The reduced chi-square statistic shows you when the fit is good. Or you can try to find the best fit by manually adjusting fit parameters.
PhET: Center and Variability
Center and Variability allows students to explore and compare measures of center and variability, including mean, median, range, IQR, and MAD.
PhET: Mean: Share and Balance
Explore the mean by leveling cups of water, distributing candy bars, fairly sharing apples, and finding the balance point of a beam. Build a data set with a target mean. Challenge yourself to predict the mean before revealing it.
