Astro Labs

Dudley at Siena offers 45 minute hands-on classes that cover different fields of astronomy. These classes can be booked as outreaches. Our current offerings are listed below.

Astro Labs can be booked by filling out a reservation form and emailing it to A representative will reach out to you to finalize your program booking. All bookings are based on the availability of staff and are made on a first come first serve basis.

Pricing: Astro Labs are offered at a rate of $150 per program.

Astro Labs work best with groups of 30 or less. If you need more information or a quote for multiple/package programs, please contact us


Outreach programs are offered within 60 miles of Siena College campus in Loudonville, NY.

A $50 fee will be assessed per hour if there is an hour or more break between programs. For instances of multiple programs, the preference is for the program to take place in the same location.

An adult chaperone must be present at all times.

A maximum of five consecutive classes can be taught by our Astronomer per day.

Each workshop occurrence (including consecutive occurrences of the same workshop) requires its own set up time. The 45 minute workshop time does not include set up time.

Elementary - Nighttime! Daytime!

Have you ever wondered why the moon changes shape? Or why the sun rises in the morning and sets in the evening? Your students will use models of the moon and sun to learn why the moon goes through phases and how the rotation of the Earth causes night and day.

Elementary - Get Down with Gravity!

Gravity is one of the four fundamental forces that make the universe run. But it’s invisible! How can we learn about it? In this activity students will show that gravity is a force that always points “down” and will experiment with objects of different mass to see if heavier ones fall more quickly than lighter ones.

Elementary - Near Star, Far Star, Bright Star, Dim Star

The Sun is a very important star. Its heat and light are integral to life on Earth. But it’s not the biggest star we can see with the naked eye. So why does it look the brightest? In this activity, students will explore the relationship between distance and apparent brightness of stars and learn about the magnitude system that astronomers use to measure the brightness of objects in space.

Elementary – Meteorite Meteor-Wrong

Learn about meteorites and how they help astronomers study the formation and interiors of the planets in our solar system. Students will explore different rock samples to determine which are real meteorite samples and which are rocks from Earth.

Middle School - The Galaxy Zoo

Galaxies are massive collections of stars, gas, dust, and dark matter. But sometimes that’s about all they have in common! In this activity, students will have an opportunity to learn about what galaxy color and shape can tell us about their stars, and they can get their creative juices flowing by creating their own classification scheme!

Middle School - How Big is Jupiter?

Planets in the solar system come in a variety of sizes. Jupiter may be the most massive planet, but how much bigger is it than Earth? In this activity, students will explore the relative sizes of solar system planets and the sun by making Play-Doh models.

Middle School - How Far is Pluto?

Space is huge. Even something as close to Earth as the Moon is over 200,000 miles away! In this activity, students will learn or review the concept of an astronomical unit (AU) and develop an intuition for the distance of solar system objects. This activity can be modified for indoor or outdoor use.

High School - Our Rainbow Universe

Stars are natural nuclear fusion machines. They create heat and light by fusing hydrogen and helium, and in the process produce other elements. But stars, even our Sun, are extremely far away. How can we tell what a star is made of? In this lab, students will learn about the blackbody spectrum and how different elements emit light at different wavelengths that we can measure with telescopes.

High School - Our Expanding Universe

Ever since the Big Bang 13.8 billion years ago, the universe has been expanding. But how do we know? What types of observations would lead astronomers to this bizarre conclusion? In this activity, students will model the expansion of the universe and study how this expansion affects the light we see and the distances we measure.
