Three separate, aerated compartments of the compost container enable children to view the entire decomposition process clearly and make side-by-side comparisons between different materials. Included thermometers demonstrate temperature changes during the decomposition process.
 
What’s Happening Inside Your Compost Container? Tiny microorganisms, such as bacteria, fungi, algae, and protozoa eat the organic waste in the container. As they break down the materials, they produce heat. Different types of bacteria and fungi are more prevalent at different times. Depending on factors such as the current temperature, pH, oxygen level, amount of water, and type of food available.
 
Many children think of bacteria and mould as bad. Explain to students that these types of organisms are beneficial to us all because they clean up the earth’s ‘trash’ by literally recycling organic material and turning it back into rich soil from which new living things can grow.
