Get Your Students Started in Sky Watching

Posted: Friday, September 30th, 2011

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! For a sample issue of the Sky Calendar and subscription info, visit www.pa.msu.edu/abrams/skycalendar/.

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.

Participate in Chemistry Education Research Study, Earn $500-800 Dollars!

Posted: Tuesday, May 9th, 2017

WestEd, a non-profit educational research agency, has been funded by the US Department of Education to test a new molecular modeling kit, Happy Atoms. Happy Atoms is an interactive chemistry learning experience that consists of a set of physical atoms that connect magnetically to form molecules, and an app that uses image recognition to identify the molecules that you create with the set. WestEd is conducting a study around the effectiveness of using Happy Atoms in the classroom, and we are looking for high school chemistry teachers in California to participate.

As part of the study, teachers will be randomly assigned to either the treatment group (who uses Happy Atoms) or the control group (who uses Happy Atoms at a later date). Teachers in the treatment group will be asked to use the Happy Atoms set in their classrooms for 5 lessons over the course of the fall 2017 semester. Students will complete pre- and post-assessments and surveys around their chemistry content knowledge and beliefs about learning chemistry. WestEd will provide access to all teacher materials, teacher training, and student materials needed to participate.

Participating teachers will receive a stipend of $500-800. You can read more information about the study here: https://www.surveymonkey.com/r/HappyAtoms

Please contact Rosanne Luu at rluu@wested.org or 650.381.6432 if you are interested in participating in this opportunity, or if you have any questions!

Lessons Learned from the NGSS Early Implementer Districts

Posted: Monday, May 8th, 2017

On March 31, 2017, Achieve released two documents examining some lessons learned from the California K-8 Early Implementation Initiative. The initiative began in August 2014 and was developed by the K-12 Alliance at WestEd, with close collaborative input on its design and objectives from the State Board of Education, the California Department of Education, and Achieve.

Eight (8) traditional school districts and two (2) charter management organizations were selected to participate in the initiative, becoming the first districts in California to implement the Next Generation Science Standards (NGSS). Those districts included Galt Joint Union Elementary, Kings Canyon Joint Unified, Lakeside Union, Oakland Unified, Palm Springs Unified, San Diego Unified, Tracy Joint Unified, Vista Unified, Aspire, and High Tech High.

To more closely examine some of the early successes and challenges experienced by the Early Implementer LEAs, Achieve interviewed nine of the ten participating districts and compiled that information into two resources, focusing primarily on professional learning and instructional materials.

Using Online Simulations to Support the NGSS in Middle School Classrooms

Posted: Monday, May 8th, 2017

by Lesley Gates, Loren Nikkel, and Kambria Eastham

Middle school teachers in Kings Canyon Unified School District (KCUSD), a CA NGSS K-8 Early Implementation Initiative district, have been diligently working on transitioning to the Next Generation Science Standards (NGSS) integrated model for middle school. This year, the teachers focused on building their own knowledge of the Science and Engineering Practices (SEPs). They have been gathering and sharing ideas at monthly collaborative meetings as to how to make sure their students are not just learning about science but that they are actually doing science in their classrooms. Students should be planning and carrying out investigations to gather data for analysis in order to construct explanations. This is best done through hands-on lab experiments. Experimental work is such an important part of the learning of science and education research shows that students learn better and retain more when they are active through inquiry, investigation, and application. A Framework for K-12 Science Education (2011) notes, “…learning about science and engineering involves integration of the knowledge of scientific explanations (i.e., content knowledge) and the practices needed to engage in scientific inquiry and engineering design. Thus the framework seeks to illustrate how knowledge and practice must be intertwined in designing learning experiences in K-12 Science Education” (pg. 11).

Many middle school teachers in KCUSD are facing challenges as they begin implementing these student-driven, inquiry-based NGSS science experiences in their classrooms. First, many of the middle school classrooms at our K-8 school sites are not designed as science labs. Learn More…

May Through July 2017 with Web Resources for the Solar Eclipse of August 21, 2017

by Robert C. Victor. Twilight sky maps by Robert D. Miller. Graphs of planet rising and setting times by Jeffrey L. Hunt.

In spring and summer 2017, Jupiter is the most prominent “star” in the evening sky, and Venus, even brighter, rules the morning. By mid-June, Saturn rises at a convenient evening hour, allowing both giant planets to be viewed well in early evening until Jupiter sinks low in late September. The Moon is always a crescent in its monthly encounters with Venus, but is full whenever it appears near Jupiter or Saturn in the eastern evening sky opposite the Sun. (In 2017, Full Moon is near Jupiter in April, Saturn in June.) At intervals of 27-28 days thereafter, the Moon appears at a progressively earlier phase at each pairing with the outer planet until its final conjunction, with Moon a thin crescent, low in the west at dusk. You’ll see many beautiful events by just following the Moon’s wanderings at dusk and dawn in the three months leading up to the solar eclipse. Learn More…
