Dropping Mentos® candies into a bottle of soda causes a foamy jet to erupt. Although science fair exhibitors can tell you that this geyser results from rapid degassing of the beverage induced by the candies, the precise means by which bubbles form hasn't been well characterized. Now, researchers reporting in ACS' Journal of Chemical Education used experiments in the lab and at various altitudes to probe the mechanism of bubble nucleation.

The best way to engage with children in museums is to listen to them, watch what they are doing, and offer explanations as the child is beginning to explore an exhibit--not before or after.
In advancing research to tackle the problem of burgeoning global economic inequality, researchers at Simon Fraser University used a poverty simulation game called SPENT to foster greater understanding of what causes poverty and economic inequality.
A new study published in The Journal of Nutrition Education and Behavior (JNEB) builds on years of previous research studies and demonstrates the value of family meals. This study showed that more frequent family meals were associated with better dietary outcomes and family functioning outcomes. While Americans celebrate the month of March as National Nutrition Month, these findings underscore the myriad benefits advanced by family meals advocates over the past few years and punctuate the official launch of the Family Meals Movement.
Researchers in this observational study of 43,000 twins born in Scotland used linked maternal and educational data to identify the optimal gestation week for the birth of infant twins associated with the lowest risk of short- and long-term adverse outcomes, specifically perinatal death and special education needs later on in school.
At a time when there's been a sharp uptick in partisan critiques of the credibility of the news media and growing concern among educators about student media literacy, a new study finds a strong connection between high school social studies teachers' political ideology and how credible they find various mainstream news outlets.
