Party With the Stars (please note we will not have a program in April)
Friday, May 18 • 8:00-9:30 pm Find out what objects are currently in the night sky and where to find them. Following the indoor program, we will set up telescopes outside for viewing, weather permitting.
Space Place family workshops are offered during the school year on Saturdays at 10 a.m. for
children ages 6-10 and their families. The workshops are free and open to the public. No registration is required.
Please note that our workshops start promptly at 10:00. If you arrive after the workshop has begun, you may miss the instructions for that day's activity and the science concepts behind it.
March 24 - "Bouncy Balls" - Experiment with polymers and find the best recipe for making your own bouncy ball.
March 31 - "Puff Mobiles" - Make a wind-powered car out of life savers, straws and paper.
April 7 - No Workshop - Instead we encourage you to visit one of the venues open for Science Expeditions (see below under "Special Events").
Space Place guest presentations are always free and open to the
public, and are offered the 2nd Tuesday of every month.
Tuesday, April 10 • 7:00-8:00 pm
"Measuring Starlight Deflection During the 2017 Eclipse: Completing the Experiment that Made Einstein Famous"
Corey Bruns, UW-Whitewater Mathematics Dept.
In 1919, Sir Arthur Eddington traveled to Africa to test Einstein's theory of General Relativity; specifically, a prediction that the Sun's gravity would bend starlight by about twice as much as Newtonian physics would predict. This could be measured by using a telescope to image stars near the sun during a total solar eclipse. He was able to take 3 images, and using 2 of them, announced that Einstein's theory was confirmed. Subsequent analysis of all 3 images indicates that this conclusion wasn't clear cut. Similar experiments were carried out in 1922, 1947, 1952, 1954, and 1973 without much improvement in results. A space-based telescope, which does not need an eclipse, was able to measure the effect with very high precision in the 1980s; so the science is settled. What's not settled is if it is possible to measure this effect from the ground - is it possible to get better precision with 21st century technology? Dr. Bruns viewed the August 21 total solar eclipse with modern equipment to do a sort of historical reenactment/experiment. Can we use statistics on hundreds of images to see starlight deflection from the ground?
Unfortunately we are no longer offering workshops to build your own telescope. For nearly a decade we have been helping families assemble these kits at Space Place However, the Galileoscope kit is not longer being produced and we are unable to order more. You may still be able to find the kit at some on-line retailers by searching for "Galileoscope".
Science Expeditions (UW-Madison campus) April 6-8• Various times and locations
Come explore UW-Madison and experience science as exploring the unknown. Talk with researchers, visit science venues across campus, enjoy Science Spectacular Shows, and try your hand at our interactive Exploration Stations. From astronomy to zoology, UW Science Expeditions is the annual campus-wide science open house that connects you to UW people and places.
