Moon and Tides Lab: Where Is the Moon Tonight?

Grades 6-8 · 45 minutes · Earth and space science, Astronomy

Many students think the Moon is only out at night and that Australia sees a different phase. Students start with a half Moon in the afternoon sky, play the day until it sets after midnight, then solve three puzzles: name a phase from above, place the Moon to make a picture, and set the clock to the moment a full Moon rises. The same night in Sydney shows the same phase, turned over. For homework, they predict tonight's Moon and go out to check.

At a glance

Essential question

How can you tell where and when to look for the Moon?

Objectives

Students will be able to:

  • predict when a phase rises and sets from where the Moon is compared with the Sun
  • find the Moon in the daytime sky and say which phases are seen by day
  • place the Moon to make a given sky, and name a phase from the positions
  • explain why people in Australia see the same phase turned over

Vocabulary

Rise and set, Horizon, Third quarter, Waxing gibbous, Southern hemisphere

Standards

MS-ESS1-1

Time and materials

45 minutes, grades 6-8.

  • One computer or Chromebook per student
  • A projector
  • The worksheet and exit ticket, one copy each per student
  • The rubric, one copy per student if you grade the work
  • Optional: a compass or a phone compass app for the Moon watch at home

Prep

Make copies of the worksheet and exit ticket. Before class, open mytekdev.com/try/moontideslab?lesson=where-is-the-moon-tonight&ref=tpt-moontideslab-4 once on a student computer: it opens on a half Moon at 2 in the afternoon, low in the east over the beach. Press Play until it sets, then try the first three puzzles, about ten minutes. Check tonight's phase so you know what the Moon watch will find.

Assessment

  • Formative: the questions under What to look for, asked while students work, and the exit ticket (answer key included).
  • Summative: the worksheet, scored with the rubric.

Technology and privacy

Lesson sequence

MinutesStageWhat you doWhat students do
0 to 5Warm-up
Hook
Show the title, essential question and Today I can slides (about 1 minute). Then the warm-up: who has seen the Moon in the daytime? Record the answers.Answer the warm-up on the worksheet.
5 to 12Direct instruction (I do)
Model it
Project the app. A half Moon at 2 in the afternoon: from above, a quarter of the way round from the Sun; from the beach, low in the east. Show A half Moon after lunch, then The same night in Sydney.

It's working when: If the Moon is up during class, take everyone to a window. A first quarter Moon is up all afternoon.

Fill in the vocabulary.
12 to 22Guided practice (We do)
Follow the Moon together
Students open the link or scan the QR code. The guide asks them to play the day until the Moon sets, then solve Name the phase, Place the Moon and When does it rise?, then switch to Sydney.

Watch for: Students who drag the Moon to change the time. The Moon sets the phase; the small person sets the time of day.

Follow the guide and write the set time on the worksheet.
22 to 38Independent practice (You do)
The rise table
Students put the Moon at new, first quarter, full and third quarter, and use One hour later to find when each rises and sets. Walk the room with the What to look for questions.

If they ask: "Each phase rises about six hours after the one before it. Why six?" The pattern

Fill in the rise table and circle the phases seen by day.
38 to 45Closure
Showcase and the Moon watch
Show the Showcase slide. Hand out the Moon watch: students press Tonight in the app, save a prediction, and go out tonight to check. Hand out the exit ticket.Answer the exit ticket and save a Tonight prediction.

Before you teach: a ten-minute walkthrough

Open mytekdev.com/try/moontideslab?lesson=where-is-the-moon-tonight&ref=tpt-moontideslab-4. A half Moon at 2 in the afternoon, low in the east over a beach in Boston, with the Sun high in the south.

  1. Play. Press Play. The Moon climbs to the south at sunset and sets in the west after midnight.
  2. Name the phase. Open Puzzles. The Moon is drawn from above, past first quarter: waxing gibbous.
  3. Place the Moon. A half Moon high in the south at about 6 in the evening: drag the Moon to first quarter and the person to evening, then press Check.
  4. When does it rise? A full Moon over Boston at the moment it rises: drag the Moon to full, then use One hour later until it is just above the eastern horizon.
  5. Sydney. Pick Sydney, Australia. The same phase, turned over: from there you face north to see the Moon.
In Model mode the clock is sun time and the Earth's tilt is left out, so rise times are near the textbook times: first quarter about noon, full about sunset. Real dates gives real clock times for your town.

Background for the teacher

The Earth turns once a day, so the Moon rises and sets like the Sun. Where it is compared with the Sun sets when: a new Moon rises with the Sun, a first quarter about noon, a full Moon about sunset, a third quarter about midnight. The Moon moves on along its path each day, so it rises about 50 minutes later each night.

So the Moon is in the daytime sky on most days. A first quarter is easy to see in the afternoon, a third quarter in the morning. Only within two or three days of new Moon is it lost in the Sun's glare.

In one survey, 53% thought Australia sees a different phase on the same night. Everyone sees the same phase; from the southern hemisphere it is turned over, because you face north to see it.

What to look for

Ask these while students work. A student who has understood the lesson can answer them without help:

The third question is the real test: the Moon's place on its path sets the phase, the Earth's turning sets where it is in the sky.

The Moon watch, for homework

In the app, Tonight asks for a prediction: the phase and which way to look at a set time. It is saved. Students go out, look, and record what they saw, or that it was too cloudy, which counts once the prediction is saved.

Check tonight's phase before you set it. Near new Moon there is nothing to see in the evening; pick a night near first quarter, when the Moon is up all evening.

Cross-curricular extensions

Vocabulary

Rise and setWhen the Moon comes up over the eastern horizon and goes down in the west, as the Earth turns.
HorizonWhere the sky seems to meet the land or sea.
Third quarterA half Moon three quarters of the way round, lit on its left side from the north. It rises about midnight.
Waxing gibbousMore than half lit and growing, between first quarter and full Moon.
Southern hemisphereThe half of the Earth south of the equator, where Australia is.

Differentiation

English learners

  • Keep the vocabulary slide up, and point east and west in the room as you say "rise" and "set".
  • Pair each learner with a partner; the rise table is times.
  • Accept the Moon watch as a drawing of the sky with the Moon.

Students with IEPs or 504 plans

  • Pair students, one clicking and one recording.
  • Zoom the browser to 150%.
  • Allow two phases in the rise table where the IEP allows a modified assignment.

Students who need more support

  • A sentence starter: "A first quarter Moon rises about ___ and sets about ___."
  • Fill in the full Moon row together.
  • Use the clock in the corner of the beach view to read times.

Students ready for more

  • Turn on Real dates and find when tonight's Moon really rises in your town.
  • Pick Quito, on the equator: which way is the crescent turned there?
  • Explain why the Moon rises about 50 minutes later each day.

Adapting for other grades

Younger students: In grades 4 and 5, do the guide and the full Moon row only, and make the Moon watch a drawing; drop the third rubric row; total 8, and 6 meets the objectives.

Older students: In high school, switch the level to High school and read the Moon's altitude and azimuth, then use Real dates to compare a winter full Moon with a summer one: high in winter, low in summer.

Name: ______________________________

1. A first quarter Moon rises about (A) sunrise (B) noon (C) midnight

2. On the same night, people in Australia see (A) a different phase (B) the same phase, turned over (C) no Moon

3. A friend says the Moon only comes out at night. What would you tell them?

Answer key: exit ticket

QuestionAnswerWhy
1BIt is a quarter of the way round from the Sun, so it rises about six hours after the Sun.
2BThe phase depends on where the Moon is on its path, the same for everyone. From the south you face north, so it looks turned over.
3It is often up by dayMost phases are up for part of the day; a first quarter is up all afternoon. A full answer names a phase and a time.
