21 Trash Math Worksheet Assume each person produces 4.5 pounds of garbage per day. 1. Multiply the number of people in your classroom or community with the amount of garbage they produce each day. (number of people) X 4.5= lbs. of garbage each day in your classroom or community. Great Pacific Garbage Patch Video Link: The Great Pacific Garbage Patch Time: 2:45 2. Multiply that number with 30 to get the pounds of garbage produced in one month. pounds X 30 days= pounds. 3. Now divide the number of pounds by 2,000 to find how many tons are produced. pounds/2,000= tons of garbage per month. It costs about $ per ton to throw away garbage. How much does your school or community spend throwing away the garbage? tons of garbage per month X $ per ton= $. This is the cost of your school s or community s monthly garbage.

26 Recycling Worms Recycling Worms Edible worm bins Worms Make Learning Fun. Worms teach us about habitats, reducing waste and taking care of our environment. Creating an Edible Worm Bin Worm bins can be made out of used plastic. The plastic cup is your worm bin. Making Worm Bedding Worms need bulky bedding such a shredded newspaper and dried leaves. We will use cereal in our edible bins. Worms need some soil. We will used crushed Oreos. Worm Diet Worms like a vegan diet. They like fruits, vegetables, coffee grounds, moldy bread. We don t like moldy bread so we will use dried fruit and cereal as our worm food. We Need Worms We will use gummi worms for our edible worm bin. Biology worm stations Soil Science and the FBI F is for Fungus Why would we feed our worms moldy bread? Mold is a fungus and it releases enzymes that break down organic materials like bread. B is for Bacteria Bacteria have many jobs in making compost. One job is to keep the compost warm. Another job of bacteria is to break down organic materials to the nutrients can be released. I is for Invertebrates Invertebrates are animals that do not have a backbone. Worms are invertebrates. Invertebrates break down organic matter and poop castings. They also aerate or add air to the soil. Worms are very important for healthily soil. Borrow our worm bin supplies and make a worm bin for your classroom. Make your own worm bin to keep all year. Worm sit our Red Wigglers for a time to observe how they recycle food scraps.
