A Galileo (also known as Galilean) thermometer is one style of temperature-sensing device. These days, a Galilean thermometer typically looks like a tall, sealed glass cylinder containing clear liquid in which several small glass bulbs are floating.
With warm, moist air on its way, there is bound to be exciting weather storms forming. So, why not try these weather and earth science experiments with your young students today to learn and have fun doing it!
Summer is getting closer and the temperature is heating up! To stay cool and have fun while doing it, make sure you attempt these dry ice experiments with your students in class or at home. They’re safe and fun for the whole family.
Historically, people with failing lungs due to diseases such as emphysema and cystic fibrosis face a grim prognosis: only 10 to 20 percent of lung transplant patients survive for 10 years. And until now, progress in creating lungs in the lab has been thwarted due to the organ’s complex structure and multiple cell types, according to biomedical engineer Laura Niklason of Yale University.
After more than 250 years of absence, the bald eagle has returned to nest along Pittsburgh’s three rivers. The majestic bird of prey was nearly extinct, but thanks to an aggressive protection program, their numbers are on the rise.
Are you looking forward to Earth Day? Be prepared by watching these fun experiments and trying them with your students on Earth Day!
Immortalized by the gas burner bearing his name, Robert Wilhelm Bunsen, a German chemist, didn’t invent it (Michael Faraday did). But, along with physicist Gustav Robert Kirchhoff, Bunsen did invent the spectroscope and improved Faraday’s burner for his work in spectrum analysis.
Ever notice that when you spill coffee over the edge of your cup it always produces a ring under the bottom edge? There is a rather complex reason for this, but it can be summed up somewhat easily. Two main factors are at play: surface tension of the molecules of the liquid and the temperature of the surrounding environment.
Though Homer Simpson may portray nuclear engineers as donut-eating slackers, that is certainly not the case. These individuals are “like a cross between a jet pilot and a firefighter: highly trained to keep a technically complex system running, but also prepared to be the first and usually only line of defense in an emergency,” says Michael Friedlander, a nuclear engineer.
Do you know which famous scientist’s birthday was yesterday? In case you haven’t heard, 2014 was the 205th anniversary of Charles Darwin’s birth, and the 155th of the publication of On the Origin of Species by Means of Natural Selection. Born in England on February 12 (the same day as Abraham Lincoln), Darwin is best known for his observations on how species change or evolve gradually over time.
