How Much Weight Can A Plastic Bag Hold?

Determining how much weight a plastic bag can hold.

Aim:

To determine the amount of weight plastic bags taken from different sources will hold/withstand.

Hypothesis:

That the Big W plastic bag will hold the most weight.

Materials and Apparatus Needed To Conduct This Experiment:

  • Weights (6kg, 4.25kg, 2kg, 1,kg, 50g)
  • Canned food( for smaller weights)
  • Plastic Bags X 4 from each source
  • Calculator
  • Pole
  • Bench presser

Risks Assessment:

The risk in this experiment is very low, although some precautions should still be taken.

Inclosed shoes must be worn at all times as to protect feet from having a weight fall onto them, conduct the experiment in an environment away from breakable objects, cloths must be placed underneath the plastic bags as to protect the floor from weights which may fall onto it.

Method:

  1. Put on covered in shoes.
  2. Place cloths on the floor underneath the plastic bags.
  3. Collect plastic bagsX4 from different shops/sources.
  4. Collect different sized weights.
  5. Set up bench press with bar.
  6. Put plastic bag on the end of bar.
  7. Add weights until it breaks.
  8. Repeat this with the other three bags from that source for accuracy.
  9. Repeat experiment with the other store plastic bags.
  10. Record observations.
  11. Graph data.

Results:

Inference:

It can be inverted from these results that plastic bags from supermarkets are stronger than plastic bags from other shops.

Discussion:

From the result, it can be seen that plastic bags can hold more than 15kg, nearly every bag (except for target) managed to hold 20kg or more, who proved my hypothesis to be incorrect.

The results of the test may have been affected by the way the weights were put in i.e: if little weights were placed in first or if larger weights were. This may have altered the results and the outcome may have varied.

The supermarket bags have been designed to hold more weight (i.e. groceries and milk) and the target bags has been designed to hold just clothes. This would also affect the outcome of the bags from target.

By conducting the following experiment we can roughly see how much weight a plastic bag can hold. For a more detailed result we would need to repeat the experiment several times on a larger scale.

Conclusion:

The investigation into the amount of weights a plastic bag can hold did not support the hypothesis by majority of the findings. The conclusion here is that the supermarket bags (i.e. franklins and Woolworth’s) were able to support more weight than department store bags (i.e. Target and Big W). Generally plastic bags can hold a weight equal or greater than 15kg.

  1. Plastic bags should be band from the earth because it is gobbling
    up all of are natural resources and is making a very large amount in littering. Please take this in concern.

  2. good work lol my school got one of those science assignments this helped me alot and this was my plan as a experiment as well

  3. yeah this helped me alot aswell. i picked the same experiment and it was really good

  4. Hey my school had on of these S.R.P. booklet to fill out which goes towards 30% of your final school report. So this experement has helped me alot… a real lot!!!

  5. u guys got a great grafhs but to big

  6. i think that big w bags are much stronger than target bags cause ever time i go there right in the store my bag ripe and they have to double my bag

  7. this was really bad

  8. woolworths. lol.

  9. what was the independent and dependent variable in this test?

  10. Any chance that the course you guy were doing was applied science?

  11. related studdy????????????????

  12. This experiment helped our hole class with our assessment task it was really awesome.

  13. ally its actully whole silly billy lol cyaaah

  14. Hi my name is Brittany Sullo tooo. i googled my name and this came up thats sooo weird! So theres another brittany sullo, holy ccrap!

  15. i love pussy!!!!!!!!!!!!!!!!!1 and douch bags hold more than any bags and are better for the enviorement….bitches

  16. Thanks, Helped me with My research project… however i need help with part 2!

  17. Special edd someone dropped him on his head now he thinks hes a pieace of bread, HES JUST A LITTLE BIT SPECIAL.

  18. WoW, this is all the awnser to my school homework (Assessment) hopefully i would get the best result.
