Science World has a number of volunteer opportunities for graduate students.

• Community Scientist Initiative (CSI)
  Science World’s new Community Scientist Initiative (CSI) is looking for scientists, researchers and other science-based professionals with a keen interest in engaging with public audiences, to become science communicators and ambassadors. Participants also receive professional enrichment workshops focused on building skills to effectively engage public audiences. Community Scientists refine key messages related to their areas of expertise and practice simple techniques for talking science with non-scientists.
  See downloadable program description.
  
• Scientists and Innovators in the Schools (SIS)
  Scientists & Innovators in the Schools (SIS) is a program that helps address British Columbia's need for more scientists, engineers, technologists and technicians to promote students' interest in these areas. Our goal is to inspire students with exciting, in-school presentations by real scientists. The program is offered to Grades K–12 everywhere in BC. See the volunteer signup form.
• Facility Volunteers
  Science World volunteers receive a wide array of benefits, including challenging and rewarding job responsibilities, education programs, training, lounge privileges, inclusion in staff events, restaurant and store discounts and a comprehensive recognition program. Email volunteerresources@scienceworld.ca

As well, volunteers in the Community Scientist Initiative will enjoy exhibit and OMNIMAX passes to share with family and friends and receive invitations to special events and social receptions, and letters of acknowledgement and professional documentation, suitable for sharing with supervisors and for grant reporting.

The best way to get better at public speaking is to do it often. This kind of volunteer activity gives you a chance to practice your presentation skills in front of many supportive audiences — especially if you design a demo that involves blowing things up. (Plus, skills that you may learn for engaging an 8-year-old's attention are often similar to skills needed to interest 48-year-old faculty members!)
