For ages 6-12. Campers will be split off into two age groups. Read the descriptions below to learn about each group’s focus.

Ages 6-8

What do a pizza, a bike wheel, and a bubble have in common? They’re circles! Why are circles special? In this fun-filled spring camp week, we will gather in our own circle to get curious about this form in art and nature around the world! We will make a variety of art and crafts, using mediums such as printmaking, painting and sculpture to create and explore color wheels, collages, mandalas, dream catchers, and more!

Ages 9-12

Thinking as inventors, artists and environmentalists, students will explore the beautiful ecosystem that is Lake Merritt, with the goal of understanding how we can better the world around us. This hands-on class challenges students to design and create innovative solutions for environmental challenges. Students will learn to combine engineering principles, technology, sustainable materials, and creative problem-solving to develop eco-centric inventions – all while letting their imaginations run wild! In our explorations, we will use ProCreate on ipads, 3d printers and Makey Makeys all while exploring principles of design, automation, and adaptability!

SLIDING SCALE PRICING & SCHOLARSHIPS

All JCAS classes are made available to families on a sliding scale. Families choose the amount they are able to pay, considering the top end of our scale is how much it costs us to run the class. We encourage families to help support our efforts to make programs available to those in need.

If the sliding scale prices are still out of your family’s budget, we do offer scholarships. Applications are accepted on a rolling basis. Please give us 7 business days to process applications. All scholarship requests must be made before March 25th.

Don’t worry about classes filling up, we account for this and ensure every camp is available for scholarship students.

PROJECT UTER at the LAB

Join us for a presentation of PROJECT UTER, a huge collaborative drawing on the struggle for reproductive justice by Tonina Matamalas and Carles Garcia O’Dowd, a sister project of the Beehive Design Collective.

The gigantic portable mural will be on display from Feb 19 – Feb 22 11 – 5pm, culminating in a presentation on Saturday, Feb 22 from 4-6pm, before it heads off to another stop. You don’t want to miss this opportunity!!

From Carles: 

This project took almost two years to make, it maps out the complexities and forces that operate when it comes to deciding over our own bodies. It started amidst huge protests in Spain for the right to access safe abortions. We interviewed people about the issue and slowly crafted a mind map that was then translated to drawings. Each scene represents a “small” picture, and interconnects with every other scene to give us the “big picture “. We have been giving oral storytelling presentations with it around the world ever since. This project was a huge learning experience and one I’m deeply proud of.

Sigrid Hubbell

Awestruck by the endless diversity, adaptations, and resilience of the natural world, Sigrid Hubbell spends the majority of her time in her urban garden cultivating flowers, herbs, food, medicine, and habitat. Growing and preserving the botanicals that comprise her work, she observes the vivid lessons revealed by natural rhythms. She hopes that noticing the contour of a leaf, the color of a petal, or the plumage of an individual seed invokes deep appreciation for the elegant intelligence and healing qualities of plants.
