Climate Change and Bees


   
So why the bee pictures? It’s all about climate change and the significance of these little residents that we share our planet with. A point is that climate change will certainly have an impact on the human population but perhaps even more serious will be the harm it does to Earth inhabitants like the Bee and its important work of pollinating plants.

   Here is an interesting an informative video from NASA about Bees, pollination, and how the Bees are used in a study about climate change effects..

   Keep informed about climate change with these smartphone apps from NASA.

Remember: Earth is our home, our only home.

NSTA @ Nashville


   I’m in Nashville Tennessee for the next several days at the NSTA national conference. Planets and stars will still be in the skies but not as easy to see from downtown Nashville as it is where I live. On the morning of April 1st the waning waning crescent Moon will be within a few degrees from Dwarf Planet Pluto. Too dim to be seen without a large telescope it is, nonetheless, a neat idea that when you look toward the Moon you are also looking in the direction of Pluto. It’s out there!
   And here is a sequence of graphics showing the pre-sunrise morning sky at 5:30 am EDT for each day during the conference, and one night view on April 1st showing Jupiter. Both Pluto and the Moon are located just above and to the left from the handle of the teapot asterism for Sagittarius the Archer.

June Solstice

Sun's Apparent Motion Along the Ecliptic

Sun’s Apparent Motion Along the Ecliptic – from Taurus to Gemini

   Northern hemisphere spring comes to an end and its summer begins at 12:04 am CDT (05:04 UT) on 21 June as the Sun ‘reaches’ the celestial coordinates of 23.5oN and 6 hours right ascension. With respect to the Earth’s surface the Sun is described as over the Tropic of Cancer, 23.5oN of the Earth’s equator. At this same time the Sun is still within the boundaries of the constellation Taurus the Bull – but just barely. Interestingly 9 hours later, (9:00 am CDT – 14 UT), the Sun ‘will move’ into the region of Gemini as it crosses the boundary between Gemini and Taurus.
   We know that it is the Earth’s orbital motion around the Sun giving rise to the sun’s apparent eastward motion amongst the stars in the background. This is how the Sun ‘reaches’ a celestial coordinate, how it ‘crosses’ the boundaries between constellations, or how it is ‘in‘ a constellation.
   With respect to the southern hemisphere this is the end of their summer and start of their fall season so thinking globally my preference has been to use the name of the month to designate the season change. Hence the use of the term June Solstice rather than the limited to northern hemisphere term summer solstice.

   Follow the seasons by observing how vegetation changes during 1 year. The video below was produced by an Earth orbiting satellite operated by the NASA/NOAA Suomi National Polar Orbiting Partnership (NPP). It is a really interesting narrated tour of the Earth from orbit over a variety of geographic features and landscapes.

Life in Tornado Alley

   Living in western Missouri near the stateline with Kansas places us in the area of the midwest known as “Tornado Alley”. While we have been very fortunate to not have had any tornadoes close by we have had to deal with the severe weather that accompanies tornadoes – including winds over 50 mph, and like this morning some really heavy torrential rains with thunder and lightning. In the span of less than 30 minutes the creek (aka the ‘river’ as our granddaughters call it) rose over its banks and flooded into the backyard. The base of the creek is at least 3 feet below the bottom of the fence and as the pictures show the water rose more than halfway up the fence and into the yard.

Free Engineering Book

book   Just a quick note to alert you to a free book download for the Kindle. The book, Engineering Stories, is written by an engineer colleague of mine, and contains seven short fiction stories about engineers and how they do what they do. The stories are well written and allow the reader to follow the path an engineer takes from initial brainstorming through the development process to the final product.
   If you are doing anything related to STEM education or are just a curious type then I would recommend this book for you and your students.
   The entire book is available as separate stories and are all free and each may be downloaded from the author’s web site address.

It’s Our Home

   “It’s our home, our only home” is a quote I came across and copied into my collection. It is from a video I used in my classroom many years ago. Can’t remember the video name nor find it but nonetheless it makes a powerful statement about our home planet. So this posting is in the spirit of celebrating our home planet.
   Monday the 22nd is Earth Day, an annual event sponsored by individuals, groups, and organizations who are activists (this is a positive use of the word), or stewards striving to create a more healthy environment for all. This is accomplished through education as well as events such as Earth Day.
group-large   Two years ago I joined with a group of musicians to form Dark Matter, a group of educators, scientists, musicians, and artists with the initial purpose of producing a series of Astronomically-based videos that would accompany a live musical performance. The videos were originally developed for use in the full dome video system at the Gottleib Planetarium at Union Station in Kansas City. The dome was approximately 60 feet in diameter and could seat around 150. The original videos were warped to suit the projection system however the two below are flat screen versions of the videos.
   The performance was called Orbit and with that as a theme I developed the videos with the compositions the composers provided. The style of music is described as electro-acoustical and was a combination of live combined with digitized sound samples and real-time sound sampling as the musicians played. The videos below were the opening and closing compositions and both were called Water Meditation. In the first piece the flute is played by Rebecca Ashe, and the second piece has a clarinet played by Cheryl Melfi. Music is composed by Daniel Eichenbaum and Richard Johnson with Richard also doing the real-time sampling during the performance.

The Banner graphic is from a high altitude balloon launched as part of the production for another full dome video and live performance called Ascent. This was during the fall of 2011 and is a view from 95,000 feet of the two neighboring cities of Kansas City Missouri and Kansas Kansas City Kansas.

   Water Meditation – Flute by Richard Johnson: Earth is a water world with more than 70% of its surface covered with water. Gain a different perspective of the planet as you orbit the Earth with a satellite. Flute is played by Rebecca Ashe.

   Water Meditation – Clarinet by Daniel Eichenbaum: As the closing composition I wanted to leave the audience with a sense of what it would be like to orbit the Earth with the International Space Station. So from that perspective we see a sunrise from orbit and our home planet as the rising Sun brightens the daylight side of the Earth. Clarinet is played by Cheryl Melfi.
