You can have a ton of science fun with a straw. You can make it into a blow gun, using the properties of air, or it can double as a pipette when your lab has run out. But did you know you can perform some awesome hands-on science with the straw’s wrapper, too? It’s true. With the Wrapper Worm, we’ll reveal how to turn an ordinary straw wrapper into a growing worm!

When does the Age of Aquarius begin? And what is the Age of Aquarius? The Age of Aquarius is not part of astronomy. It’s an astrological age, which occurs because of a real motion of Earth known as the precession of the equinoxes, which, for example, causes the identity of the pole star to change over time. The cycle of precession lasts 25,800 years, and there are 12 constellations of the Zodiac. So, roughly every 2,150 years, the sun’s position at the time of the March, or vernal, equinox moves in front of a new Zodiac constellation. The Age of Aquarius begins when the March equinox point moves out of the constellation Pisces and into the constellation Aquarius. When will that be? There’s no definitive answer. Various interpretations give different answers to this often-asked question.
As March 2017 opens, the waxing crescent moon joins up with Venus, Mars (and Uranus) in the western sky after sunset. Continue reading
