August 2016 has rare gifts for skywatchers — for most of the month, all five naked-eye planets can be seen during evening twilight, and they participate in beautiful pairings and groupings! From a site with an unobstructed view of the western horizon, begin within half an hour after sunset, to catch Venus before it sinks too low. Use our evening twilight chart and diagrams selected from the Abrams Planetarium Sky Calendar to guide you.

Venus at mag. –3.8 will be visible with unaided eye. (It will get higher in coming months, setting in a dark sky starting in October, climbing highest in January 2017, and reaching spectacular brilliance at mag. –4.8 in February, before quickly departing from the evening sky in late March.)

Jupiter, next in brightness at mag. –1.7, is easy to find not long after you spot Venus. For most of August, Jupiter appears to upper left of Venus, 1° closer to it each day until their spectacular close pairing on Sat. Aug. 27, described below. Thereafter Jupiter will appear to lower right of Venus.

Use binoculars all month, if necessary, to catch Mercury, starting August at mag –0.1 while 8° upper left of Venus, and fading to mag. +0.5 by Aug 24 while 6° lower left of Venus.

As the sky darkens, Mars (mag. –0.8 to –0.3), Saturn (+0.3 to +0.5), and first-magnitude Antares 6° from Saturn all month become easy for unaided eye. The two planets and the red supergiant star will have a striking arrangement Aug. 23 and 24.

Watch for these events (data for California sky watchers): 

In morning twilight Aug. 4-14, look daily within an hour before sunrise and watch for the first appearance of Procyon about 6°-7° N of east, and Sirius in ESE. Sirius is nearly in line with Orion’s belt, and completes the almost equilateral Winter Triangle with Betelgeuse (Orion’s shoulder) and Procyon. Look up the meanings of these stars’ names, the meaning of the term heliacal rising, and reasons for the importance of Sirius to ancient Egypt.

Aug. 4, beginning 30 minutes after sunset: Find 2.3-day-old crescent Moon low in west, and Venus 11° to its lower right. Mercury appears 2° left of Moon, nearly 9° upper left of Venus, and 15° lower right of Jupiter. Mars-Saturn are 10° apart in southern sky. Six solar system bodies, Venus-Mercury-Moon-Jupiter-Mars-Saturn, span 100°.

Aug. 5: Jupiter about 1° above Moon. Mercury remains 9° from Venus Aug 4-16 (max. dist. 9.2° on Aug. 10).

Aug. 6: Three planets, Jupiter-Mercury-Venus, appear 12°, 24°, and 33° to lower right of Moon. Mars and Saturn appear 57° and 65° to Moon’s upper left. Venus and Mars appear 90° apart – in quadrature this evening. Verify that by observation!

Aug. 7 and 8: Moon near Spica, brightest star in Virgo.

Aug. 8 and 9: Mars 0.9° from Delta Scorpii, middle and brightest of three stars in head of the Scorpion. Moon passes First Quarter phase at 11:21 a.m. PDT on Aug. 10. Tip for teachers and students – telescopic observation of Moon in daytime: When Moon is within 2 days before or after half full – this month, on afternoons of Aug. 8-11, near First Quarter phase, and on mornings of Aug. 23-26, near Last Quarter phase, thread a single polarizing filter into a low-power eyepiece of your telescope. Next, while viewing the Moon, rotate the eyepiece until the blue sky surrounding the Moon appears darkest, increasing contrast of Moon against sky for wonderful daytime views of lunar craters and other features!

Thurs Aug. 11: As darkness falls, note the beautiful diamond-shaped arrangement of Moon-Mars-Antares-Saturn, about 6°-7° on each side. Tonight’s moonset occurs just over halfway from sunset tonight until sunrise on Friday. Peak of the Perseid meteor shower occurs after moonset, in Friday’s predawn darkness hours! The dark, moonless sky should be wonderful for observing meteors.

Aug. 12: Moon 8° upper left of Saturn. The famous ringed planet marks the top vertex of an attractive triangle of three “stars”. Compare color and brightness of its two other members, Mars and Antares. Venus 15° lower right of Jupiter and 1° closer each day!

Aug. 16: Mercury at greatest elongation, 27° E of Sun. Since Mercury is more to left of setting Sun, rather than high above it, the planet sets well before darkness falls, and this is an unfavorable apparition for observers at mid-northern latitudes, despite Mercury’s unusually large angular distance from the Sun. Folks in southern California will have an easier time spotting it than folks in northern part of the state.

Wed Aug. 17, dusk: Venus 10° lower right of Jupiter. Ten days to go! Five planets span 84°. Also, Full Moon overnight, at 2:26 a.m. PDT on Thursday. Moon shines with enhanced brightness in that hour as it narrowly misses penumbra of Earth’s shadow and reflects sunlight toward us and source of illumination; look up opposition effect.

Aug 19: Mercury 3.8° lower left of Jupiter, their minimum distance apart in a quasi-conjunction.

Aug 22: Venus 4.9° lower right of Jupiter! Aug 23: Ve-Ju = 3.9°, Me-Ju = 4.3°, Me-Ve = 6.4°, in a nearly isosceles triangle.

Aug 23 and 24: In order from top to bottom, Saturn, Mars, and Antares nearly line up, as Mars goes 4.4° S of Saturn and 1.8° N of Antares!

Aug 25 predawn (telescope): Moon occults 3.7-mag Gamma Tauri, point of “V” of Hyades star cluster, 1:17-2:10 a.m. PDT from Palm Springs, CA. Daytime occultation of Aldebaran visible through telescope: Disappearance on Moon’s bright side occurs in Palm Springs at 10:24 a.m. PDT, and reappearance at Moon’s dark side at 11:27 a.m. Last Quarter phase occurred on Aug 24, at 8:41 p.m. PDT, so Moon on Aug. 25 is a fat crescent. Follow waning Moon mornings through Aug. 31.

Aug 25: Ve-Ju 1.8°. Aug 26: Ve-Ju 0.8°.

Aug 27: This is the first evening Jupiter appears to lower right of Venus. The planets are just 0.2° apart, as seen from California — and about 0.1° apart from eastern U.S. – alert your friends in that part of the country! Mercury, faded to mag +0.8, appears 5.1° S (lower left) of the bright pair.

Aug 28: Ve-Ju 1.2° apart. Their separation increases by about 1° daily. Ve-Me 5.0° apart, the minimum distance for this passage.

Aug 31: Ve-Ju 4.3° apart, Jupiter getting lower each evening. On what date will you last spot Jupiter?

Sept. 1: New Moon, 2:03 a.m. PDT.

Sept. 2: Find 1.7-day-old thin crescent Moon very low in west, 4.5° lower right of Venus. Can you spot Jupiter within 2° to Moon’s lower right? Mercury is already gone, and Jupiter will sink into the solar glare within a few days.

Thriving in a Time of Change

Posted: Wednesday, September 13th, 2017

by Jill Grace

By the time this message is posted online, most schools across California will have been in session for at least a month (if not longer, and hat tip to that bunch!). Long enough to get a good sense of who the kids in your classroom are and to get into that groove and momentum of the daily flow of teaching. It’s also very likely that for many of you who weren’t a part of a large grant initiative or in a district that set wheels in motion sooner, this is the first year you will really try to shift instruction to align to the Next Generation Science Standards (NGSS). I’m not going to lie to you, it’s a challenging year – change is hard. Change is even harder when there’s not a playbook to go by.  But as someone who has had the very great privilege of walking alongside teachers going through that change for the past two years and being able to glimpse at what this looks like for different demographics across that state, there are three things I hope you will hold on to. These are things I have come to learn will overshadow the challenge: a growth mindset will get you far, one is a very powerful number, and it’s about the kids. Learn More…

If You Are Not Teaching Science Then You Are Not Teaching Common Core

Posted: Thursday, August 31st, 2017

by Peter A’Hearn 

“Science and Social Studies can be taught for the last half hour of the day on Fridays”

– Elementary school principal

Anyone concerned with the teaching of science in elementary school is keenly aware of the problem of time. Kids need to learn to read, and learning to read takes time, nobody disputes that. So Common Core ELA can seem like the enemy of science. This was a big concern to me as I started looking at the curriculum that my district had adopted for Common Core ELA. I’ve been through those years where teachers are learning a new curriculum, and know first-hand how a new curriculum can become the focus of attention- sucking all the air out of the room.

Tools for Creating NGSS Standards Based Lessons

Posted: Tuesday, August 29th, 2017

by Elizabeth Cooke

Think back on your own experiences with learning science in school. Were you required to memorize disjointed facts without understanding the concepts?

Science Education Background

In the past, science education focused on rote memorization and learning disjointed ideas. Elementary and secondary students in today’s science classes are fortunate now that science instruction has shifted from students demonstrating what they know to students demonstrating how they are able to apply their knowledge. Science education that reflects the Next Generation Science Standards challenges students to conduct investigations. As students explore phenomena and discrepant events they engage in academic discourse guided by focus questions from their teachers or student generated questions of that arise from analyzing data and creating and revising models that explain natural phenomena.
