Selections vary from week to week. Each activity is led by a trained staff member or volunteer and includes interactive, hands-on activities.  

Our activities cover a broad spectrum of scientific topics. In one 45-minute activity, students may learn about: 

  • Fossils: Explore the worlds of paleontology and archaeology, focusing on the formation, excavation and examination of fossils.
  • Water Chemistry: Investigate the properties of water through a series of water-related experiments to learn more about cohesion, adhesion and density.   
  • Fibonacci: Learn about the amazing Fibonacci sequence (0+1=1, 1+1=2, 1+2=3, 2+3=5) that is found in nature and featured in five art installations in the Town Center of the Discovery Building.
  • Moon Drop: Take on the engineering challenge! Build a spacecraft to help your astronauts land safely on the moon.
  • Mesozoic: Travel back in time to the Mesozoic Age to explore what the Earth looked like during the time of the dinosaurs.
  • And more!

When You Arrive
Activities will start promptly. Please consider arriving a few minutes early so you are prepared to begin on time.

Upon arrival, please check in with a staff member at your Afterschool Expeditions location. Once you are checked in, you will be directed to your first 45-minute activity. Once that activity has been completed, participants will switch to a second activity. Staff will lead participants to their activity location during the switch. Participants are requested to stay at their activity for the full 45 minutes.

Participant Expectations
Participants are encouraged to listen and follow directions of Afterschool Expeditions staff, volunteers and/or group chaperones.

Chaperones and parents are expected to stay with their youth at all times. Additionally, chaperones and adults are encouraged to assist in activities, ask questions and assist with keeping youth engaged.

For participants at the Discovery Building, we encourage youth to view the interactive science displays and have fun, but please keep in mind that the Discovery Building is a research facility and professional workplace.
