The 3 side-by-side plastic compartments of this container allow classes to compare the compost rate of different materials or to design their own experiments. Add Redworms (item #141650) or fungi, Chaetomium globosum (item #155973), to examine the effects organisms can have on decomposition. Track the compost process visually through the magnification windows. The ventilated chambers keep the compost aerated to minimize odors. Teach measurement and data collection skills by recording the temperature in each compartment daily with included thermometers. Includes teacher's guide with activity ideas and more. Container size, 12" W x 4" D x 8" H.
