CALENDAR OF EVENTS..
October 8th – Scout STEMpede-Bear Paw
up on what else may come up for discussion..
Oct. 15th Scouting Jamboree On The Air… J.O.T.A. Modern technology offers Scouts the exciting opportunity to make friends in other countries without leaving home. JOTA is an annual event in which Boy and Girl Scouts and Guides from all over the world speak to each other by means of Amateur (ham) Radio.
Things that we have historically scheduled:
October: Nomination of Board members and Plan Christmas Party: JOTA (Jamboree on the Air)
A little science as we get ready for STEM..
According to science lore, Galileo dropped two balls from the Leaning Tower of Pisa. In fact, it seems unlikely that Galileo actually carried out this experiment. But he supposedly was trying to show that those balls would fall with the same acceleration. Their change in speed due to gravity would be the same, no matter what they were made from or how much they weighed.---- Einstein’s equivalence principle holds that this inertial mass is equal to the gravitational mass. And if that’s true, then two different objects should fall at the same rate (at least when they’re in a vacuum, where air resistance is eliminated). In a perfect vacuum, for instance, a feather will accelerate just as much as will a ball of iron.
Scientists have now performed a similar experiment in a satellite. They dropped two hollow cylinders and measured them for more than 120 orbits. The cylinders were in free fall for about eight days’ worth of time.
In the satellite experiment, the two cylinders’ accelerations did match — at least to within two-trillionths of one percent!
By the way, one cylinder was made of platinum alloy and the other from titanium.
