Purpose

• The purpose of this project is to find out which
  trash bag can hold more weight for a longer time,
  Glad or Hefty?
• The problem of this project is that we dont have
  a clue on which bag could hold more, so we
  researched each bag.
• Both Andrew and Jack had the hypothesis that
  Hefty would be able to hold more weight than Glad.

3
Controls/Variables

• Controls
• We started with 15 pounds and went up 5 pounds
  every 15 seconds for both bags.
• Did two tries for each bag.

• Variables
• We used two different trash bags, Glad and Hefty.
• The weight increased 5 pounds for every 15
  seconds.

Research Abstract

• Hefty
• Hefty trash bags are very good for food storage.
• They are 1.01 mm thick in material.
• Uses a technology called Puncture Protection to
  prevent ripping or tearing.
• They have an unscented odor block to keep the bad
  odor in the bag.

• Glad
• Glad trash bags are made of polythene and are
  100 recyclable.
• They are .95 mm thick
• They dont contain plasticizers.
• They use a technology called SELFing or
  Structurally Elastic Like Film.

Materials List

• The materials we used for this project were
• Glad trash bags,
• Hefty trash bags,
• Weights,
• Stopwatch, and
• A pen and paper (to record the data.)

6
Steps for project

• We put 15 pounds in a trash bag (Glad or Hefty)
• Lifted up bag and every 15 seconds add 5 pounds
  until bag rips.
• Repeat process for each trash bag.

Results

• As a result of the project, Glad was a better
  trash bag because it held more weight for a
  longer time for both of the bags we tried.
• Hefty was a big disappointment to both of us.
• If I were you I would listen to the quote from
  the Glad commercial, Dont get mad, get Glad.

9
Conclusion

• So in conclusion, both of our hypotheses were
  wrong. Glad was a better trash bag because it
  could hold more weight for a longer time.
• Even though Glad is a little more money, I would
  suggest to your parents to buy them to save some
  cleaning up.

10
Synthesis

• You should buy Glad instead of Hefty.
• Glad will keep you out of those Trash disasters
  where it would take hours to clean up.
• So once again, tell your parents to buy Glad!
