    Here are some lessons , prepared by B. Ed. student Fabiano Micoli, in which you can integrate the study of the sun into your astronomy course.

    Here are some activities related to light pollution, an astronomical topic with connections to science, technology, society, and environment.

    Globe at Night is a worldwide "citizen science" project is which students can measure and analyze light pollution in and around their community.

    Zooniverse is a set of astronomy-related "citizen science" projects in which students and the general public can participate and contribute to scientific research.

  5. Some Public Presentations (in Addition to the Above) by JRP

    One World, One Sky, One Amazing Universe a celebration of astronomy, culture, and our amazing universe.

    One World, One Sky, the same, without the amazing universe!

    Galileo's Legacy: why Galileo was celebrated in IYA, and what has transpired in astronomy in the last 400 years.

    Misconceptions about the Universe: From Everyday Life to the Big Bang: a tour of the universe, highlighting misconceptions which the public have about astronomical topics. These range from true misconceptions, to problems of astronomical language, to widespread pseudoscientific beliefs, to ones based on a literal interpretation of scripture.

  6. Cross-Cultural Astronomy

    In the industrialized world, we tend to think of astronomy in terms of exciting discoveries about the nature of the universe. But, for most people on Earth, now and in the past, astronomy was important for its practical applications (time-keeping, calendars, navigation), and for its deep cultural connections (determining date and direction, for religious purposes, and questions of the nature and meaning of things that were observable in the sky). "Multi-cultural" astronomy provides a way of connecting with people of all cultures, and of recognizing astronomy's deep cultural roots.

    Teachers' Activities and Resources to multicultural astronomy, published by the Astronomical Society of the Pacific, and prepared by Toronto teacher and education researcher Dr. Nalini Chandra.

    Resource Guide to Multicultural Astronomy, published by the Astronomical Society of the Pacific, including references on the astronomy of many cultures, including North American Aboriginal cultures.

    Activities and Lessons on multicultural astronomy, developed by Heather Kristjanson, University of Toronto, working with me. These are especially suitable for the elementary level, and for making cross-disciplinary connections with social studies, and arts.

    One World, One Sky: a powerpoint presentation on astronomy and culture.

    Integrative Science: an approach developed at Cape Breton University, and the Mikmaq College Institute, for combining Western and indigenous ways of knowing about the natural world.

  7. Variable Stars!

    My research is on variable stars, stars which vary in brightness. This is the leading area by which skilled amateur (volunteer) astronomers can contribute to astronomical research. The best source of information and opportunities is American Association of Variable Star Observers (AAVSO) . Teachers and students: I especially recommend Variable Star Astronomy by which students can develop and integrate their science and math skills, motivated by doing real science with real data.

    Variable Stars: Action in the Sky an overview of variable stars, ways of observing them, how amateurs can help, and how my research students are benefitting from their work.
