Classroom trash

A bag of trash were collected from different classrooms to a group to sorted out.











First we weigh the bag before we begin to sort them out.














We dump the trash on the tarp. There were a lot of paper and food scraps.














Next we sort the trash. We create different piles of: bottles,paper,food, and etc.













Then we weigh the piles. There were 70% of paper, 60% percent of food, 50% of bottles, and 40% other materials.


















We can reduce consumption and disposal the materials by using the 4R's. We can reuse the paper scraps for art classes. We can use the food scraps for the grassy areas to compost. The plastic bottles we can throw at a trash can. The other materials like batteries for example we can't just throw them in a garbage can because theres mercury in it.
In a classroom theres usually a lot of paper in the garbage can. What we can do is get a recycling bin and put next to the garbage can. Another way to save paper by using a computer but the thing is we are going to use a lot of electricity. But think about it we can save the trees for more oxygen.

Litter Survey

We take pictures of areas before lunch and after lunch. The areas that we take picture are grassy area between hallways, administrative wing, front of school quad, and quad hallway. we compare the difference between before lunch and after lunch. The quad hallway was so clean its like a straight clean path that you can cross without getting dirt in your shoes. Before lunch the areas was very clean maybe just a few wrappers but it doesn't harm anything. After lunch was a disaster there were garbage everywhere. The quad hallway was really dirty I guaranteed that there at least a wrapper stuck to your shoe.

4R's at home


I separated the glass bottles and plastic bottles in a different bag. The picture you see is a bad example of the 4R's because I about to put my plastic bottle to the glass bottles. Its better to separate the materials because you don't want to recycle a material that doesn't belong to that category. Good thing we have technology to separate, clean, and compost materials so we can reuse them again.

Hey! What sup people! ^_^

Tennyson High School has team up with Alameda Country of Education using a cool program called SLWRP at Tennyson High School. Community Multimedia Academy has practicing the 4R's (reduce, reuse, recycle and rot) to help us to recycle in a cool way. Its a new technique to recycle in a useful way. We can save our environment by recycling and use materials again and again.
