Leaping Towards Leap Day ~ 2024

Leap Day

Do you know any Leaplings? That is a word to describe folks born on Leap Day.

Leap Day has become a fun and unique day that only revolves around every four years. 

Once every four years, people born on Feb. 29 actually get to celebrate their birthday.  Leap day and Leap Year is when an extra day is added every fourth year to help fix the problem that while our calendar year is 365 days, the solar year — the amount of time it takes the Earth to circle the sun — is 365.24219 days.

Leap Day was even the subject of a super funny episode of Frasier, during a Leap Year episode in 1996. In this episode, “Look Before You Leap,” Dr. Frazier Crane encourages his family and friends to Leap into a daring new practice in honor of Leap Day. 

When Frasier’s turn came to sing an aria at the PBS telethon, he choked! We pass around various versions of this excerpt in the faculty forums at our school.  Thought you might get a smile out of this one If you can find the Frasier episode (Season 3/Episode 16) that features Leap Day, it is fun to watch! 

Here’s a fun Leap Day math quiz that you may want to take and then share with your students! 


Happy Leap Day!

STEM for All Video Showcase Begins Monday, May 15, 2017

STEM for All Video Showcase starts Monday May 15!

At the STEM for All Video Showcase next week (May 15-22), more than 150 projects will showcase three-minute videos of their innovative work by gifted students and educators. Researchers, practitioners, administrators, policy makers and the general public are invited to view the videos and interact with the presenters online. Past showcases have drawn more than 20,000 participants. Please schedule a few minutes to click over to the STEM for All Video Showcase and learn, discuss, and connect!

Math Conversations Go Global

Would you get up at 2:00am to discuss math concepts? Students in Kenya did tonight! They slept at their school in order to participate in an online, global Fuze meet-up w/ high school math students from two schools in California. This project is under the supervision of Dr. Eric Hamilton of Pepperdine University.

All students’ insightful, engaging conversations and discussions of their STEM projects were illuminating for me. “Illuminating” is a word of hyperbole but it fits tonight after listening to these insightful students. Boundaries can be shattered from just these types of conversations!

Happy Birthday Michael Minovitch

While we were celebrating the new year yesterday, Michael Minovitch celebrated his birthday.

I hope he had an out of this world birthday because he is the reason we know so much about the outer planets of the solar system. Dr. Minovitch proposed the solution to the “three body problem” that would propel the Voyager spacecrafts from one planet to the next using that planet’s gravitational power. Voyager 1 launched in September, 1977 and Voyager 2 launched in August, 1977. The Voyagers contain gold disks with “The Sounds of Earth” an idea from Carl Sagan. Click the link from “the Sounds of the Earth” to hear them.

Traveling at 50,000 miles an hour, over 10 miles a second. Voyager 1 is out in deep space is now over 11 billion miles from Earth and passed most of the power of Sun’s gravitational grasp (see the real-time distance measurement at this link.) Its twin, Voyager 2, has flown past all the outer giant planets, of Saturn, Uranus, and within 3,000 miles of Neptune in 1989.

The maths required for Voyager 2 to fly over Neptune required mathematical accuracy within one second and weather forecasting on a planet 3 billion miles away from Earth. Both Voyagers have flown farther than Pluto into interstellar space.

Now in a mission over 35 years, data from the Voyager transmiter, takes over 15 hours to arrive back to scientists at the Jet Propulsion Lab in Pasadena, California. And it all began with Dr. Michael Minovitch’s math of the “three body problem.”


Innovative Finnish-American research collaboration

http://www.innovationsforlearning.net/In early 2013 a collaboration between Finnish and American education researchers took a step forward as Science Across Virtual Institutes was formally launched. Called SAVI for short, Science Across Virtual Institutes brings together sixteen research groups. Each of the eight groups from Finland partners with a group from the US forming eight teams.

“In SAVI education experts from Finland and the USA work together with the aim of improving student engagement in STEM,” summarizes professor Jari Multisilta, who heads the Finnish side of the collaboration. The SAVI program is funded by both Finnish and American sources: the Academy of Finland, Tekes (the Finnish Agency for Technology and Innovation) and the US National Science Foundation. Multisilta believes that motivation for both researchers and supporters stems from a general concern: “Policy makers are becoming more and more aware of the challenges linked to the low popularity of STEM subjects. In the future we will need an increasing number of skilled STEM experts to maintain and develop our societies and economies sustainably.”

The SAVI research teams specialize in different topics of learning innovations in science and mathematics:

  • WEPS Advancing an Online Project in the Assessment and Effective Teaching of Calculus
  • eTEXTBOOK Dynamic Digital Text: An Innovation in STEM Education Finland
  • EAGER Engagement in STEM learning and careers through the use of innovative learning activities
  • VIP Video Inquitry Project. STEM Learning and Teaching with Mobile Video Inquiries and Communities
  • FUN: Finland – US Network for the Study of Engagement and Learning in Games
  • GROMINDS Graphogame and MindStars Books: Global Cyber Tools for Improving Young Learner’s Reading Comprehension, Scientific Discourse and STEM Learning
  • PDE Studying & Supporting Productive Disciplinary Engagement In Demanding Stem Learning Environments Across Cultures And Settings
  • UNCODE – Uncovering Hidden Cognitive Demands on Global Learners

Teaching Scale-A Resource

Teaching scale to studated a series of images that ents can be one of the most challenging endeavors. If it were easy, we probably wouldn’t need the reminder on our car’s side view mirrors that “objects in the mirror are closer than they appear.”

Or is it further away? {gasp}

Perhaps Ron Miller can help. Miller, a space artist, computed and created a series of images of each of the planets as they would look if they were 240,000 miles away, which is the approximate distance of our moon.
