The Secret Science Club presents Astrophysicist and Cosmologist David Hogg, Wednesday, January 18, 8 PM @ the Bell House, FREE!

Our galaxy, the Milky Way, contains at least 200 billion stars and 50 billion planets. It is just one of about 350 billion galaxies in the known Universe.  And astronomers believe that closer observation and mapping of our own stellar neighborhood may help unfold the story behind the Universe’s evolution.

Cosmologist David Hogg peers into the night sky and asks: --What can new space missions and digital surveys tell us about Dark Matter and Dark Energy? --What came before the Big Bang? --How are Black Holes detected? And how do we know the Universe is expanding?
The co-author of over 100 scientific papers, Dr. Hogg is an associate professor at NYU’s Center for Cosmology and Particle Physics, and works with the Gaia Space Mission, an international effort to create the largest and most precise ever 3-D chart of the Milky Way, the Sloan Digital Sky Survey III, and the citizen science project, Astrometry.net.
Before & After --Groove to heavenly sounds --Stick around for the scintillating Q&am…

Using diagrams to explain force and motion....

Q:What can we notice about the motion of the marble on the roller coaster tube?

1. Explain:Share the concept of forces and motion using a United Streaming video clip or using a nonfiction text.  I like to use snippets from United Streaming to show a real roller coaster in motion.  The kids get a "Wow" factor and an immediate hook....
2. Label a diagram of a roller coaster to show:
*marble’s position (near the top, traveling down, etc…)
*force – push or pull (we use a push to start the marble, then gravity pulls it along)
*motion – how the marble moves (up, down, forward, backward)
This may seem "elementary" but many kids do not connect the science behind the "fun" until they draw it out on a diagram in their notebooks.

I don't know if you can see, but this student wrote all the key words for direction up, forward, down, stop - but never connected it to the vocabulary term motion.  He also didn't write anything about force.  This example is one that shows…
