Daisies & Brownies

Space Science Explorer/Adventurer

Daisies and Brownies get ready to explore the sun, the solar system, the moon and the stars by the constellations. We will teach you how to make a paper model of the layers of the sun called a Sunion; create a moon wheel to track the phases; use instruments and your imagination to explore the mysterious regions of the moon; construct constellation viewers and make wearable models of the solar system. Make your trip complete with a visit to the telescopes for day and night viewing 



Space Science Investigator

Earn your Space Science Investigator badge by spending a night of solar system discovery. You’ll learn how to identify the planets, stars and constellations. In your workshop you will find out how solar systems are formed and how scientists use the transit method to detect distant objects like extra solar planets. You will create fun scale models of the planets and hike the distances between them.



Space Science Researcher

Cadette Researchers, spend an amazing night all about deciphering light from stars and other objects in the night sky.  We will teach you to use real scientific tools and instruments to reveal some of the hidden regions of the electromagnetic spectrum such as infrared and ultraviolet light. We will demystify how different stars are classified as we work together to build a giant star classification diagram. You will visit the observatories and telescopes to collect observations and lastly, you contribute to citizen science research on light pollution.
