Teen Volunteer Interns, a program at the Lawrence Hall of Science, receive training every second Saturday of the month. In addition to community building and reflection on practice exercises, training includes better ways to communicate science to public audiences, as well as how to facilitate different exhibits and demonstrations. In today’s session, a group of the TechHive teens also received a brief overview of Math on a Sphere, learned some basic commands, and then were turned loose to create a design of their choice. Teens also began to write up their ideas into instruction cards to be used in future camps for younger children. There was a Pokeball under construction and a great seasonal pumpkin appeared! Here is a short video of a Rainbow Wheel made by a pair of teens.
