SUMMARY:Washburn Observatory Open House
DESCRIPTION:We will be opening the Observatory to the public regardless of weather\, though we hope for favorable weather so we can use the telescope to look at some astronomical objects! Come see the historic 15.6″ Clark refractor and enjoy the view of the night sky atop beautiful Observatory Hill\, following traditions of our ancestors for over 10\,000 years. The dome is open to the outside air so dress appropriately. Food and drinks\, as well as flash photography are not allowed in the observatory. \nIn the event that weather is not favorable on the 17th\, the Observatory will be open on October 24th from 7-10pm.

SUMMARY:Badger Talk - ACORNS (Activities for Community Outreach in STEM)
DESCRIPTION:This is a free\, in-person talk hosted on October 17\, 2026 at 1:00 PM by Iron Ridge Public Library in Iron Ridge\, WI. Registration is encouraged\, but not required. More info to come on how to register. There will be no virtual option for this event. This event is a part of the Wisconsin Science Festival!\n\nStudies show that feelings of belonging are the number one indicator of retention in STEM. The ability of students to see themselves in STEM spaces is crucial to building this sense of belonging. At the same time\, students are only able to envision themselves as scientists in as much as they are doing science. An ACORNS program is a highly interactive\, tactile STEM-themed activity. These could include modeling planet formation with ice cream and cookies\, exploring stellar fusion with the ingredients of s’mores\, and measuring the speed of light using a chocolate bar.\n\nThis shift from a lecture-style format to a hands-on\, student-led dialogue allows for an immersive STEM experience\, highlighting both that science can be fun\, accessible\, and messy\, but also that anyone is capable of doing it\, regardless of expertise. Science is a state of mind\, defined by curiosity–and every person has plenty of that.\n\nZach Lewis is a graduate student in astronomy at UW-Madison. His research focuses on the evolution of elements inside galaxies. He uses JWST observations of distant galaxies to characterize how stars produce elements and eject them into their host galaxy\, and how those elements then escape the galaxy or form new stars.

SUMMARY:PRE-FESTIVAL EVENT: International Top Spinning Day - Spin Tops Wherever You are in the World!
DESCRIPTION:SPIN TOPS TODAY & CELEBRATE INTERNATIONAL TOP SPINNING DAY because the EARTH IS A TOP! It’s a free WORLD-wide event: in school\, at home\, at work (on break): WHEREVER you are this day. \nWHY? To recognize & celebrate the scientific fact that the Earth is a Spinning Top + it’s a combo of fun & learning: science\, math\, fine motor skills\, organization\, challenges\, observations skills. Every culture around the world spins tops. \nHOW TO TAKE PART: Each time you start a top spinning\, it counts as a spin!\nSet up lots of tops for everyone to spin. Small trays\, lunch trays or paper plates work for a place to spin. Keep track of the number of each start of a spinning top. Then email us the total spins of your group\, your city\, how many participants\, ages\, comments\, and photos\, too\, please: thetopmuseum@hotmail.com \nOFFICIAL! This activity has been recommended by the National Science Foundation discussed on National Public Radio\, written about in Family Fun Magazine! It even appeared on TV in Kansas! Kids in Romania\, professors in Poland\, Families in Wisconsin\, people in South Africa\, New Zealand and many other places have taken part in past years. Visit our website for more places. \n–This event was founded by the Top Museum director 26 years ago in Wisconsin!\nThere will be free top spinning in front of the Top Museum from noon-6pm this day\, but spinning counts for the entire 24 hours of Oct.14\, wherever you are in the world today! \nCheck out more events at the Spinning Top & Yo-Yo Museum and the Logic Puzzle Museum!
