Bad garbage grows and grows and grows.
Students will identify good garbage examples they saw during the exploration phase and will also recognize that items from Lesson Two that people throw away are bad garbage items. Students will study a large poster showing the different stages of composting and will name these stages. Students will list different types of food that are okay to put in the composter. Students will recognize that composting is a means of natural recycling and thus, a way to reduce trash. Students will also recognize that compost is good for plants.
