A Sample of Our OPEF BASE Camps

Science of Sweets

Science of Sweets takes a close look at the delicious science of sugar. Campers examine how temperature influences crystal formation and see first hand how science works to create different textures in sucrose. Density, saturation, and dynamic equilibrium are just a few terms that are explored.

Biking Adventures

During biking adventure, campers learn and practice bike maintenance and biking safety as they ride to destinations such as Thatcher Woods, local cafes and recreation areas. This camp provides opportunities for our campers to become more comfortable on their bike as well as learn more about places that they can bike to in our community.

Experimentation Station

Experimentation Station is all about hands-on experiments with things gooey, strange, stinky, colorful, eruptive, surprising, and always fun! Campers hypothesize about the science behind the reactions they see.

Shoe Drip & Apparel Art

During Shoe Drip/Apparel Art, Campers embellish and customize their own gear. Using paints, bling and other materials, campers design their own unique pair of footwear and other apparel that they then take home.

Earth Ambassadors

Our Earth Ambassadors camp is all about the science of sustainability — from climate change to biodiversity to alternative energy — to help our campers become more informed citizens and effective activists. Campers engage in hands-on projects, guided discussion and immersive field trips.

Cardboard City

During Cardboard City, campers design and construct a small-scale city with upcycled cardboard. Campers learn about the structural properties of different types of cardboard. All design, engineering, and construction is camper-led.
