Seeds rolled up in clay and compost balls make a great portable garden-starter that can be used on campus or in wasteland areas where wildflowers would be welcome. Kids can research what species of wildflowers are native and important to birds, bees, butterflies and other pollinators in the area and ask for donations from local farm and garden stores. They can participate in an engineering design challenge to discover which ratio of clay to compost works best to hold the shape and germinate an appropriate number of seedlings. Check out the Science tab at Seed-Balls.com to learn more about the soil chemistry of seed balls and the physics of flinging them.
