  • Total Lunar Eclipse January 2019

    This handout promotes and explains what happened on January 20-21, 2019 during the total lunar eclipse, visible across all of North and South America. It is also available in black and white.

  • Mercury Transit November 2019

    Learn how to safely view a planetary transit, and what extra measures need to be taken when it's the smallest planet crossing our Sun!




  • Caring for Optics

    Learn how to take care of your telescope or binoculars.

  • Dealing With Dew

    What to do about the dew on your telescope.

  • The Stellar Magnitude System

    The way we measure light from stars is a little different than the way we measure most things. As celestial objects get brighter, the number gets smaller... Click here to learn why.


New Brunswick

  • The Importance of Science Literacy

    This presentation, given by Mary Lou Whitehorne at the 2010 General Assembly of the RASC, outlines why it is so important to understand science, especially in this day and age.


Prince George

  • Graph the Constellations

    Use graph paper and coordinates to graph the constellations!

  • Crazy Craters

    Learn about why craters look and form the way they do, and how this changes depending on where you're looking: the Earth's moon, the moons of Jupiter, or our own planet!

  • Lunar Craters

    Maybe you only care about the craters on our moon, and that's fine! We have an activity just for lunar craters as well. This activity is simpler than the "Crazy Craters" activity.

  • Phases of the Moon

    Use this chart to record the phases of the moon for a lunar cycle.

  • Make a Sundial

    Use your own handmade solar clock to tell the time.

  • Make a Star Clock

    You can tell the time during the day with your sundial, but what about at night? We've got you covered!

  • Build a Refracting Telescope

    You can make your own telescope with only a few simple materials. TEach your students about telescope optics with this activity.

  • Measure the Diameter of the Sun

    Ever wondered how astronomers know how big the sun is when they have never been there before? You can do the math yourself!

  • Motion of the Earth and Sun

    Become the Earth to learn about how we move through space in this interactive activity.

  • Constructing Optics Diagrams

    Find out how light bounces around telescopse in order to make the object you're looking at appear larger than it actually is.

  • Planetary Colouring Sheets

    Colour in Jupiter, Mars, Saturn and the Sun.
