Hands-On Activities

Optional hands-on activities last 20 minutes and cost $40 per activity.

Solar System to Scale (Limit: 22 students)
Students are divided into groups to make a scale model of the solar system along the length of an indoor hallway. Students receive instructions about how many tiles they need between various planets. If your group is 23-44 students, you may split them between two back-to-back activity sessions for a total of 40 minutes for $80.

Star Charts (Limit: 68 students)
Students learn to use star charts to identify 6-10 constellations in the sky.

Preparing For Your Visit

We recommend introducing grade-appropriate astronomy topics before visiting the planetarium. This might range from basic constellations for younger students to atomic structures and the electromagnetic spectrum for older students. Any exposure will help your students engage more at the planetarium. See the Resource Materials section below.


Students may eat their own lunch in the cafeteria on the ground level of the UWM Union, a short walk east of the planetarium. Students are welcome to eat lunch outdoors, weather permitting.

Discussion Questions & Answers

Theme: Astronomical (Celestial) Objects in the Day and Night Sky

  • Discussion Question: If the Sun is the largest object in the solar system, why does the Sun look so small?
  • Answer: Because it is so far away.
  • Discussion Question: What does the Sun do for us?
  • Answer: Supports all life on Earth through the process of photosynthesis. Provides us with heat and light. Powers the water cycle which creates our weather and climate. Provides us with seasonal cycles and even sleep cycles.
  • Discussion Question: The Moon gives off its own light.
  • Answer: The Moon light we see is actually reflected light from the Sun. The shape or phase of the Moon is determined by the Moon’s position in its orbit around the Earth with respect to the Sun. We always see the same side of the Moon because it does rotate. Because it takes about the same amount of time to rotate as it does to revolve around the Earth, we always see the same side. The side we don’t see is known as “the far side of the Moon.”
  • Discussion Question: What star does Earth orbit?
  • Answer: The Sun.
  • Discussion Question: What is the shape of Earth’s orbit around the Sun?
  • Answer: Earth’s orbit is an ellipse that is close to a circle with the Sun on one focus of the ellipse. Planets orbit the Sun on slightly elliptical, or oval-shaped, paths. In addition, planets closer to the Sun complete their orbits faster than planets farther away; Mercury orbits the Sun every 88 Earth days, and Neptune orbits the Sun once every 164.89 Earth-years.

Theme: Solar System

  • Discussion Question: What is the difference between a star and a planet?
  • Answer: A star is a ball of very hot gas where nuclear fusion can occur and which produces the light that make stars shine. A planet, on the other hand, gets its light reflected from its companion star. All planets are not made of the same material. Planets are separated into two categories: inner and outer planets. The inner planets are smaller and made of rock. The inner planets include the planets closest to the Sun: Mercury, Venus, Earth, and Mars. The outer planets are often called gas giants because they are very large and made of gases. The outer planets include Jupiter, Saturn, Uranus, and Neptune.
  • Discussion Question: What is a comet?
  • Answer: Comets travel though the solar system in irregular orbits from regions beyond the orbit of Neptune. A comet is a large ball of ice and rock. Comets can be seen as they approach the Sun because the Sun’s heat melts a comet’s ice to form glowing gases that stream out into a long tail. Comets look like bright streaks in the sky.

Theme: Earth/Moon/Sun Interactions

  • Discussion Question: If the Earth is moving, why don’t we feel it?
  • Answer: We don’t feel it because the Earth is rotating at approximately 1000 miles per hour. We don’t “feel” that we are traveling at this speed because the Earth, our frame of reference, is traveling with us. The same is true of traveling in a car at a constant speed, unless you are looking out the window.
  • True or False: The Sun, Moon, and stars are always in the same places in the sky.
  • Answer: As the Earth rotates, the Sun, Moon, and stars appear to move across the sky. They rise and set. Also, the Moon orbits the Earth once a month and the Earth orbits the Sun once a year, so the Moon and Sun pass through different parts of the sky.
  • True or False: An eclipse of the Sun happens when the Moon comes between the Sun and the Earth.
  • Answer: True. During a solar eclipse, the Moon moves between the Sun and the Earth. The Moon’s shadow falls on the Earth. Solar eclipses are rare. Because the Moon is so small compared to Earth, the shadow it casts on Earth’s surface is very small. Only people in a limited area are able to see a total solar eclipse. Note that there are two kinds of eclipses: solar and lunar.
  • Lunar Eclipse: Earth moves between the Sun and the moon, blocking part of the Sun’s light from reaching the Moon. During this time, you will see the Earth’s shadow on the Moon.
    • Solar Eclipse: The Moon moves between the Earth and the Sun. This causes part of the Sun’s light to be blocked. The sky will get dark when this blockage occurs.
    • A “Total” eclipse is when the Moon and the sun are in a perfect line. This occurrence is very rare.
  • Discussion Question: What causes the phases of the Moon? What are the phases?
  • Answer: The Moon’s phases are caused by two things: 1. The Moon revolving around the Earth. 2. The Moon reflecting sunlight towards the Earth. Half of the Moon is always lit, not just the portion we see; however, sometimes we only see a profile of the lit portion of the Moon. Certain phases of the Moon result depending on its orbit, and the Moon’s orbit is responsible for the phase changes we see. Since we only see the lit portion of the Moon that is facing Earth, we see a Moon phase.
    • There are eight phases that the Moon goes through and they always occur in the same order. The Sun’s light seems to move from right to left across the surface of the Moon.
    • The phases of the Moon are: 1. New Moon, 2. Waxing Crescent, 3. First Quarter, 4. Waxing Gibbous, 5. Full Moon, 6. Waning Gibbous, 7. Last Quarter, 8. Waning Crescent, and back to the New Moon.
  • Discussion Question: Is the Sun closer to the Earth during the summer months than during the winter months?
  • Answer: The Earth is not closer to the Sun in the summer. The seasons happen because the Earth’s rotation is tilted compared to its orbit around the Sun. Summer happens for us when our part of the Earth is tilted toward the Sun, and winter happens when we are tilted away. In fact, the Earth is slightly farther away from the Sun when we are experiencing summer in the northern hemisphere. The tilt causes the Sun to reach different heights at different times of the year and to be up for longer periods of time than others. Parts of the Earth that have the Sun appear high in the sky experience summer and those that have the Sun low in the sky experience winter. Spring and fall occur when the sunlight is directly over the equator (in the middle) so for neither hemisphere does the sun appear to be particularly high or low in the sky.

Theme: Constellations

  • Discussion Question: What are constellations?
  • Answer: Constellations are patches of sky that contain a characteristic pattern of stars.
    • The patterns are often named after characters from ancient Greek and Roman mythology (although individual stars have mostly Arabic names). There are 88 official constellations. Common constellations visible from Milwaukee include the Big Dipper, Gemini, Orion, and Leo (to mention a few).
    • Some basic constellations that are always visible at Midwestern latitudes: Big Bear (contains the Big Dipper), Little Bear, Cassiopeia; visible in Spring: Gemini, Leo; visible in Summer: Cygnus, Summer Triangle; visible in Fall: Pegasus, Andromeda; visible in Winter: Orion, Taurus. Ancient people observed that the Sun, Moon, and planets always seem to move across the sky through a series of 12 constellations known as the zodiac. In particular, a person’s zodiac sign was the name of one of the 12 constellations of the zodiac that the Sun was closest to at the time of the person’s birth.
  • Discussion Question: How can you tell the difference between a star and a planet in the sky?
  • Answer: The stars in the sky appear to be in fixed positions with respect to each other. They can seem like they are attached to an imaginary “celestial sphere” around the Earth. Planets move in complicated paths across the sky. They exhibit a behavior called “retrograde motion” where they appear to go backwards for a period of time relative to the background stars in the celestial sphere as they move in their orbit around the Sun. Also, planets almost never twinkle.

Theme: Life of a Star

  • Discussion Question: How do stars form?
  • Answer: Stars are continually being formed and destroyed. Stars are formed, or born, in clouds of gas and dust in the interstellar medium. Gravity squeezes the mass of these “star nurseries” so that the centers become incredibly dense and hot. These extreme conditions allow hydrogen fusion to begin. The outward pressure from the fusion balances the inward force of gravity. The gas stops collapsing and a star is born.
