Fifth Graders are building a healthy compost pile. They began by layering GREENS — nitrogenous waste (veggie waste from juice bar Go Raw and coffee grounds from Starbucks in Liberty Station) and layering on BROWNS — carbon waste — straw (left over from the Fall Festival), a bit of garden soil for the beneficial bacteria it provides, and making the pile nice and wet. Every couple of weeks, they added a few more layers and watched the pile heat up and break down. Composting takes a few months, if it is maintained and kept moist and aerated, but by the end of the year we should have some healthy compost to use on our garden.
Next, the fifth graders will be adding signage to teach the rest of the school how to compost!
