Get Your Students Started in Sky Watching

Posted: Friday, September 30th, 2011

by Robert Victor

The current school year will be exceptionally rich for sky watching. October is a good time to get your students started!

The school year 2011-2012 will be enhanced by many spectacular sky events: evening planet gatherings, with as many as four bright planets visible simultaneously from late February until late April, and a close pairing of Venus-Jupiter, the two brightest planets, on March 13; predawn lunar eclipses on December 10 and June 4; a deep solar eclipse late in the afternoon of May 20; and a rare transit of Venus across the face of the Sun on the afternoon of June 5. In October the Milky Way passes nearly overhead at nightfall, and a sky watching session can provide good telescopic views of Jupiter and its four bright satellites discovered by Galileo, and many star clusters and other favorite deep sky objects.

Bright evening planets: Venus moves out from 13° to 20° upper left of the setting Sun in October 2011 and begins to set in a darker sky. The brilliant planet of magnitude –4 thus becomes easy for unaided eye, but you must look early, very low in the WSW evening twilight glow. Mercury emerges after midmonth, but in this poor apparition it remains low in twilight. Mercury is brighter than magnitude zero, but still much less bright than Venus, so binoculars are useful. Look just 3° lower right of Venus on the 21st. After passing below Venus, Mercury lingers only 2° lower left of the brighter planet during Oct 29-Nov. 14. Look for Venus and Mercury to the lower right of the young crescent Moon on Oct. 28. Jupiter on Oct. 1 rises N of E as darkness falls. Its rising time shifts over 4 min. earlier each day, and by the 28th Jupiter rises at sunset and reaches opposition in Aries, all-night visibility, and greatest brilliance near mag. –3. Jupiter appears near the Moon on the nights of Oct. 12 and 13, from shortly before nightfall until next day’s dawn.

On Oct. 14, Venus-Earth-Jupiter align in space. With Earth between them, Venus and Jupiter then appear to us in mutual opposition. On what date after Oct. 14 will your students first see Venus and Jupiter simultaneously? (Observers with mountains around them may have to wait until November.) Beginning on the first date some of them succeed, have them keep track of Venus and Jupiter until March 13, 2012, when they’ll form a spectacular pair just 3° apart well up in the western sky at dusk. Venus-Jupiter will then be in mutual conjunction, when Earth-Venus-Jupiter align in that order, on March 13. Coming issues of California Classroom Science and the Abrams Planetarium Sky Calendar will chart their progress between now and then as the Venus-Jupiter gap closes. Keep looking up!

Planets at dawn: Jupiter in dawn twilight begins October well up in WSW, and sinks low, N of W, by month’s end. Mars rises after midnight and by dawn twilight is high in ESE to SE. Against stars, Mars opens October at mag. +1.3 in Cancer near the southern edge of the Beehive cluster (use binoculars to see the cluster) and goes 17° E, ending at mag. +1.1 in Leo, within 6° W of Regulus, heart of Leo. Mars will pass within 1.4° north of Regulus on the mornings of Nov. 10 and 11. Saturn and Spica emerge less than 5° apart low in E to ESE morning twilight glow in the closing days of October and rise about half an hour earlier each week.

While we’re still on daylight saving time (until November 6), take advantage of the dark morning skies available at a convenient time to get a preview of the stars where theyll appear after nightfall in February and March: Orion the Hunter and the brilliant blue-white Sirius the Dog Star high in the southern to southwestern sky, and the Big Dipper and Leo high in the northeast to southeast.

Once the Moon has passed Full on Oct. 11, students can follow the waning Moon in the predawn sky for the next two weeks until Oct 25. Catch the Moon near Jupiter before dawn on Oct. 13 and 14; near the Pleiades star cluster on Oct. 15; Aldebaran, eye of Taurus on Oct. 16; Pollux and Castor, the Gemini Twins on Oct. 19; Mars on Oct. 21; Regulus, heart of Leo, on Oct. 22; and — more difficult — using binoculars 40 min. before sunrise, try for Saturn rising 10° to lower left of the last, old crescent Moon on Oct. 25.

Even if you wait until the students arrive at school, they can use the recess period before first bell, or the opening few minutes of first period, to follow the Moon with unaided eye in the daytime sky each morning from Oct. 12 or 13 (just past Full, setting in WNW) until the Moon becomes too thin and too close to the Sun to find easily in daylight, before Oct. 25. Especially for a few mornings around Oct. 19 and 20, with the Moon near Last Quarter phase (half full), if you fit your telescope’s low-power eyepiece with a single polarizing filter, and rotate the eyepiece within its tube while you’re observing the Moon, you can darken the blue sky and greatly improve the contrast between Moon and sky. Even in daylight, craters along the lunar terminator will really stand out!

  1. Y’know, there is a daytime sky as well as a night sky. Once they know how to read the clouds, students will be able to predict weather, know how sunlight and moisture team up to produce weather, and much more. It’s also interesting to compare satellite views of one’s area and what one sees from the other side. All you have to do is march the students out of the door, look up, and observe.

California Science Curriculum Framework Now Available

Posted: Tuesday, March 14th, 2017

The pre-publication version of the new California Science Curriculum Framework is now available for download. This publication incorporates all the edits that were approved by the State Board of Education in November 2016 and was many months in the making. Our sincere thanks to the dozens of CSTA members were involved in its development. Our appreciation is also extended to the California Department of Education, the State Board of Education, the Instructional Quality Commission, and the Science Curriculum Framework and Evaluation Criteria Committee and their staff for their hard work and dedication to produce this document and for their commitment to the public input process. To the many writers and contributors to the Framework CSTA thanks you for your many hours of work to produce a world-class document.

For tips on how to approach this document see our article from December 2016: California Has Adopted a New Science Curriculum Framework – Now What …? If you would like to learn more about the Framework, consider participating in one of the Framework Launch events (a.k.a. Rollout #4) scheduled throughout 2017.

The final publication version (formatted for printing) will be available in July 2017. This document will not be available in printed format, only electronically.

If you attended an NGSS Rollout phase 1-3 or CDE workshops at CSTA’s annual conference you may recall hearing from Chris Breazeale when he was working with the CDE. Chris has relocated professionally, with his passion for science education, and is now the Executive Director at the Explorit Science Center, a hands-on exploration museum featuring interactive STEM exhibits located at the beautiful Mace Ranch, 3141 5th St. in Davis, CA. Visitors can “think it, try it, and explorit” with a variety of displays that allow visitors to “do science.” To preview the museum, or schedule a classroom visit, see Learn More…

Learning to Teach in 3D

Posted: Monday, March 13th, 2017

by Joseph Calmer

Probably like you, NGSS has been at the forefront of many department meetings, lunch conversations, and solitary lesson planning sessions. Despite reading the original NRC Framework, the Ca Draft Frameworks, and many CSTA writings, I am still left with the question: “what does it actually mean for my classroom?”

I had an eye-opening experience that helped me with that question. It came out of a conversation that I had with a student teacher. It turns out that I’ve found the secret to learning how to teach with NGSS: I need to engage in dialogue about teaching with novice teachers. I’ve had the pleasure of teaching science in some capacity for 12 years. During that time pedagogy and student learning become sort of a “hidden curriculum.” It is difficult to plan a lesson for the hidden curriculum; the best way is to just have two or more professionals talk and see what emerges. I was surprised it took me so long to realize this epiphany. Learn More…
