This project is intended for elementary aged students
Do some research on the topic. In the introduction to your project you will want to include some information on why you chose this topic and why it is relevant to our lives and desires to be more “green.”
- How long does it take a plastic bag to break down in a landfill?
- How long does it take a paper bag to biodegrade in a landfill?
- What is the cost in terms of materials and labor to create a plastic bag?
- How about the cost and materials of creating a paper or cloth bag?
- What effects does creating a plastic bag have on the environment?
- What are the environmental impacts of creating a cloth bag?
- What are the environmental impacts of creating a paper bag?
- What is the cost of producing a cloth bag? How much does it cost to purchase a cloth bag?
- How many times would a cloth or canvas bag need to be used in order to be more green than a plastic bag?
- How many times would you need to use a paper bag in order to be more eco-friendly than a plastic bag?
Interview a manager at your neighborhood grocery store to find out how much it costs to purchase each plastic bag. In the write-up for your science project include the reasoning other than cost (such as environmental impacts, longevity, strength, size) behind considering which grocery bag to use.
Consider the strength of each bag. Fill the bags with heavier grocery items: 2-liter bottles of soda, gallons of milk and large cans. Compare how much each can hold before the bag rips or the handles break. You may want to conduct this experiment using items to stand in for the heavier groceries, such as bricks, so you do not ruin the food items.
Compare how much can be held in Hippo Sak® grocery bag. Fill the plastic bags with typical grocery items — such as bread, eggs, milk — and compare which bag holds more, the plastic, paper or cloth. Keep track of the average number of items each bag can hold and record those averages in your data chart.
