Bring your family, students, scouts or youth group on a unique overnight adventure. You'll enjoy a night of special programming and exploration tailored to a theme of your choice. Designed expressly for groups of children ages 6-14, overnights at the EcoTarium are educational, interactive and FUN!
Choose your program theme:
- Be a Scientist - Fizz! Pop! Wow! Conduct exciting, hands-on chemistry and physics experiments to test your hypotheses using the scientific method! Make things bubble, hover, and congeal in your hands.
- Crimes, Codes, & Clues - Put on your thinking caps and dive into the world of spies, detectives, and forensic scientists! Use logic, careful observation, fingerprint analysis, and encryption to solve a mystery.
- Engineering Design Challenge - Solve problems like an engineer! Prevent "brain" injuries by testing helmet designs and see how far your KEVA bridge can span before it collapses... then build it again!
- Mission Invention - Anyone can invent! Practice thinking outside the box to devise and perfect new solutions to the problems around you. Don't forget to market your newfangled contraptions to your friends!
- Ocean Life - Ocean environments are vast and varied - and so are ocean animals! Meet tide pool creatures, dissect a squid, and explore the life of a whale to see what living in the ocean is all about.
- Science after Dark (New Theme!) – Come explore the dark side of science! Meet some native nocturnal animals, practice your stargazing, and learn some tips for exploring the night like a science ninja!
- Stars & Space - Zip around the solar system in our planetarium, explore Mars, and launch your own rocket or land your own probe on the red planet! Observe the constellations and, weather permitting, take a look through a telescope!
Please refer to the Theme Selection Form for additional information about each theme, including activity descriptions and connections to merit badge requirements and school curriculum standards.

A Night Journey is an exciting way to experience what the EcoTarium is all about; however, since much of our time together is spent engaging in special themed programming, there is always much more to explore. Therefore, every overnight guest will receive a free admission pass so that they may return another day and continue to enjoy our extensive exhibits, animals, and grounds at their leisure.
You are welcome to use your return admission passes for the following museum day, but please be aware that you must exit the museum grounds at the conclusion of your overnight programming and re-enter museum grounds upon the start of our standard visitor day.
