Planetarium Photo

Astronomy Foundations is an online course designed to introduce and orient astronomy enthusiasts to the night sky. Over the 12 sessions, a wide range of topics are covered, from understanding our place in space, finding our way in the sky, and understanding a little more of the wide variety of astronomical objects that await your discovery. Each session focuses on a specific astronomical topic in detail. These topics will include why the sky looks and moves as it does, the nature of planets and other solar system bodies, where stars come from, how they evolve and where they’re going, and how astronomers have learned what they are and how they have estimated their staggering distances. Clusters of stars small and large as well as the great “Star Cities” - the galaxies, such as our own Milky Way will be covered. Throughout the sessions there will be reviews on how to use the star maps to find some of the best and brightest of the night sky’s offerings for yourself.

Planets are always on the move, as are we! This planetarium program series explores the planets, stars, and constellations that are visible in the night sky each month. Participants learn how to orient themselves in the sky to find the Big Dipper and how it can be used to find North. Every workshop explores at least one constellation or planet and its mythology, the brighter stars in the sky and their names, lore and meaning, as well as a few of the astronomical objects located within the boundaries of the featured constellation. If weather conditions permit, participants may be invited outside under the stars to see the real deal through a telescope.

  • January features the planets Mercury and Orion.
  • February features the planets Venus and Taurus.
  • March features the planets Uranus and Gemini.
  • April features the planet Gemini and Earth's Moon.
  • May features the planets Leo and Neptune.
  • June features the planets Virgo and Mercury.
  • July features the constellation Hercules.
  • August features the planet Mars.
  • October features the planet Saturn, minor planet Pluto, and the Constellation Cygnus.
  • November features the planets Uranus and Neptune, and the Constellation Cassiopeia.
starry sky

This planetarium program introduces the history of navigation using the stars, reviews why stellar navigation was developed, and how the North Star and Polaris can be used to determine compass points and to estimate latitude. The planetarium will be used to simulate how the stars appear to change when viewed from different latitudes on Earth. Is there such a thing as a South Star? Families are welcome and encouraged.

photo of a moon

There are currently eight planets in our solar system. Orbiting many of these planets are a wide variety of moons, each one of them with its own unique story to tell. This program explores some of the differences between planets and moons and will introduce some of the major moons of our solar system. Participants learn the definitions for celestial bodies like, “star”, “planet”, moon”, and “orbit” and the associated sizes, distances, and scales. How the motions of the Earth, Sun and our Moon and cause the Earth’s moon cycles through phases will also be covered.  The first 30 minutes of the program is spent outside of the dome working with physical models of the Earth, Sun, and Moon to help understand what we see in the sky.


This program provides an opportunity to explore the some of the basic scientific facts that have been discovered about one of our closest space neighbors - Mars. Mars appears to have once been a lot like Earth, with oceans and a dense atmosphere, but then it all went horribly wrong. Much of what we have learned about Mars has come from robotic missions that seem to give rise to as many questions as are answered. This workshop also includes a review of astronomy terms such as “planet” and “orbit”. Participants learn about the physical characteristics of Mars and how to recognize Mars and other planets in the night sky.

The Constellation Hercules - the champion - is prominently positioned in the mid-summer sky. This region of the sky also happens to be the direction toward which our solar system is heading as it makes its long circuit around the center of the Milky Way once every 250 million years or so. Although it is the 5th largest of the 88 constellations, Hercules does not contain many bright stars, but it abounds with objects that are visible even with a small telescope. Perhaps its most beautiful feature is the Great Hercules Star Cluster, a swarm of about one million bluish suns.
This workshop also includes a review of astronomy terms such as “planet” and “orbit”. Participants learn how to recognize the Constellation Hercules and other celestial objects in the night sky.

In this workshop, participants learn how to use shape and other key characteristics to simplify identifying songbirds. Learning how to ID different passerine families makes for exciting and interesting connections between different species and helps to build a story around a group of birds rather than memorizing individual species. This workshop series includes four lectures covering all of Ontario's songbird families including stories about the various survival strategies of this amazing group of birds. An optional guided walk to practice songbird family ID is also included.

Participants receive a copy of the Pond Life Biodiversity Identification Sheet.
*Maximum 18 adults when held in person.

photo of a Turtle

Reptiles are the most at-risk group of flora or fauna in Ontario.  Due to their secretive nature, many of these amazing species, are largely unknown or overlooked by many outdoor enthusiasts.  Every one of Ontario’s turtle species needs help and learning about these adorable creatures is an excellent way to assist them. Snakes are often misunderstood and maligned, but through this program we hope to change this by teaching the truth about these animals and providing opportunities to interact directly with some live specimens. Identification, ranges, and habits of our reptile species will be covered, and hands-on opportunities with some of our native snakes and turtles will make this an exciting experience.
*Maximum 18 adults when held in person.

photo of spiders

In this day-long workshop, participants learn about the fascinating life stories and identification tips about our most important invertebrate predators, the spider. Participants will venture outside for part of the day learning how to find and identify some of our amazing local arachno-fauna, discover first-hand why most insects are arachnophobic, and how we can (and should) help our local spider population.
*Maximum 18 adults when held in person.

winter invertebrates

In winter’s frigid grasp, insects, spiders and other invertebrates seem to vanish from the surface of the earth.  Knowing what to look for and where to find these hidden creatures make cold-weather expeditions far more enjoyable.  During this half-day program, participants search for goldenrod gallfly larvae and caterpillars that hide in burrs, learn how woolly bears forecast the severity of winter’s blast, and discover a great variety of other “bugs” that are surviving their most challenging season. Through photographs, hands-on bio-artifacts, and an outdoor exploration and discovery session participants become familiar with our cold and spineless neighbours. This workshop is held in winter, anticipate dressing to trek in cold and hopefully snowy conditions. A hand lens is recommended, but not required.
*Maximum 18 adults when held in person.

Plants and Mushrooms

This is really two workshops in one. In addition to learning to identify Ontario's springtime flora, participants go "beyond the field guide" to delve into the natural history, ecology, lore, and uses of these plants. Following a brief classroom session, participants spend the remainder of the workshop engaged in hands-on exercises and stimulating discussions while exploring The Arboretum's nature preserves. Wildflower field guides and a hand lenses are recommended, but not necessary.

*Maximum 16 adults when held in person.
