(9-Adult) The roll-top observatory at Turner Farm holds a classroom seminar and nighttime observing session focused on a specific astronomical topic each month. Topics include planets, comets, open clusters, double stars, stellar color spectrum, globular clusters, galaxies, nebulae and more. Telescopes are used to view the objects discussed in the classroom (weather dependent). Check the Analemma site for monthly topics. www.analemma.org. Advance registration required, no walk-in registration available.

(6-Adult) Have you ever wondered about the earth in space and the other objects that make up our universe? Bring your family and take a guided tour of the heavens and see the color of stars, open and globular clusters, nebulae and galaxies. Advance registration required, no walk-in registration available. Children must be accompanied by a registered adult.

In this pre-engineering program, offered by PlayWell, students build engineer-designed projects such as boats, snowmobiles, catapults and merry-go-rounds, then use special pieces to create their own unique design. Students explore endless possibilities using the LEGO building system.

(6-Adult) What are meteorites and where do they come from? What can they tell us? This course is an introduction to these visitors from outer space. Participants have the opportunity to touch and examine actual meteorites including specimens from the moon and Mars. The course is held in the roll-top observatory classroom at Turner Farm Park. Advance registration required, no walk-in registration available.

In this class offered by STEM exCEL, Minecraft Modding and Java programming are tied together to allow students more customization in their mods. At the same time, this course teaches students how to solve problems in a multiplayer game while building and collaborating. Students learn to advance their programming skills writing and implementing large scale Minecraft modifications. Any supply fee payable to instructor at first class.

(9-Adult) What can you hear from space? Learn about cosmic noise and what it tells us about the sun, the magnetic structure surrounding some of our planets and the strange decametric radio signals from Jupiter and its moon Io. Learn how our galaxy is mapped using the faint signals from hydrogen atoms and the behavior of molecules and the meanings behind the sounds of pulsars, strange, dense, fast-rotating stars. Come hear what our universe is saying. Advance registration required, no walk-in registration available.

(6-Adult) Course covers common and uncommon phenomena that can be seen in the open sky such as rainbows, haloes and glories. Sunrise and sunset phenomena like the green flash, the purple light and simple questions such as why is the sky blue and why are sunsets orange are also covered. This simple course teaches you how to better appreciate the sky both day and night. Advance registration required, no walk-in registration available.

In this class, offered by Play-Well, students increase their engineering skills with thousands of LEGOs. Students apply real-world concepts in physics, engineering and architecture through engineer-designed projects such as belt-driven cars, truss bridges, rail racers and pneumatic forklifts. Design and build as never before, and explore your craziest ideas.
