W hat is this strange pile in the backyard?  If you let vegetables, fruits, leaves, and grass rot in a pile, they will turn into compost. Compost looks like soil. You can put it in your garden to help plants grow.  What’s compost?
Process  of  Compost  something that can be rotten naturally soon
What's compostable?  Greens Green leaves   Coffee grounds   Tea bags   Plant trimmings   Raw fruit and vegetable scraps   Fresh grass clippings   Hair   Browns Dried grasses, leaves  and some weeds   Straw   Woodchips   Twigs and branches   Sawdust   Shredded newspaper
Food with meat, dairy or oils   Pet feces (dog, cat or bird)   Diseased plants   Weeds gone to seed   Ash from charcoal or coal   What’s not compostable?
What's compostable? (and what isn't?)
Let’s talk about! Cycle of Compost
Where Does Your Waste Go?   Most of the trash that people    throw away ends up in  landfills    or dumps.  The process starts when we put our household trash by the curb to be picked up.  Garbage trucks go into neighborhoods to pick up the trash.  Then they bring it to the landfill where the trucks dump out all the trash.  Next, machines push the trash into big piles.  Finally, the piles are covered with dirt so more trash can go on the top. Landfills-   areas where  trash is taken
Trash  decomposes  at different  rates.  Some trash takes a long time  to decompose, causing the piles to get too  big. We are running out of room for new trash.   500 yrs 400 yrs 300 yrs 200 yrs 100 yrs 50 yrs 25 yrs 0 yrs less than a year Decompose- to rot or break down glass  aluminum plastic paper food
Questions 1. What three things happen to trash as soon as it  reaches the landfills?  (Hint: Write your answer  using commas in a series.) 2. Which would decompose faster, a paper bag or a plastic bag?  Explain your answer in a complete sentence. 3. Give two examples of types of trash that take years to decompose. 4. What do you think will happen when our landfills get too full? Sample answers next
Answers 1. After trash reaches the landfill garbage trucks dump it, machines push it into piles, and soil is placed on top. 2. A paper bag would decompose quicker because it is made from trees.  Trees are a natural resource which decompose faster.  Plastics are man-made and decompose slowly.
4. If landfills become too full, we would lose land that could be used for places such as: homes, playgrounds, and schools.  The Earth would become more polluted and eventually we would run out of space.  What other ideas did you come up with? End of activity 3. Trash that would take years to decompose include: glass  aluminum plastic
Can you put more things that go in a compost bin?
