Our Recycling Project
/ Hello everyone,I am Jackson.Last Thursday,my class learned about what we can do with things we normally throw away,like plastic bottles.Afterwards,our teacher asked us to make something useful out of trash and show the class on Monday.I made toys out of toilet paper rolls.I painted thế paper rolls and added eyes,hair,and hats.My favorite toy is a silly monster with giữa eyes.I gave one ( a cute witch ) to my little sister.My friend,Riley,reused cans and plastic cups to make plant post.She painted and drew.This project was really fun and useful.I did not know that we can make so many learned about recycling last Wednesday.
