13 Ways to Use a Plastic Grocery Bag
A lowly plastic grocery sack may not seem like a versatile tool for the classroom, but don't overlook all the uses for this free and easy-to-find item. Start with these ideas, then build on your own brainstorms:
Wrap sacks around toilet paper tubes or paint rollers. Roll over wet paint-covered paper to create textures.
Inflate and tie shut, then cover with paper mache for pinatas or replicas of globes or the solar system.
Cut into strips and weave together or braid.
Use rock or sand to test the strength of the handles or the bag itself. Measure weight by hanging the bag from a fish scale.
Estimate the difference of mass of plastic bags and paper sacks when tossed in the landfill. Calculate for a household per year, and for an entire city per year.
Ecology Time Capsule
Try testing the biodegradability of plastic bags over several months. Bury outdoors and dig up before school lets out for the summer.
Put small items in a bag and tie shut. Students guess contents by feel only.
Leave a gift bag for a substitute teacher with a can of soda (or money to buy one), snacks and a thank you note. Tie shut with ribbon.
Bags are handy to send home with each student to bring leaves, seeds, plants or anything else you might need for science projects.
Keep on hand as containers for wet clothes, leaky lunches or other messes in the classroom.
A bag easily folds and fits in a pocket on field trips as an emergency cover for a cell phone, pager or camera. Use two as shoe coverings.
Store mini blackboards or whiteboards and their related supplies, one per student. Also use for markers and other art supplies.
How to Store
Spread flat and stack, then lay a large book on top of the stack. All the air will be pushed out and they'll take up nearly no room at all.
