Mandela Key Skills 12/09/14

We have had a wonderful first week back! The children have been magnificent and have worked extremely hard.

The key skills for this week:

Creative Curriculum:

This week it is very much science related. After Churchill beat Mandela in a very tense blockbluster quiz, we looked at testing the strength of seven different plastic bags. Through many discussions we realised that it was fairly impossible to make the test completely fair; we tried extremely hard to ensure that our results were as reliable as possible.

This is some of our thoughts on what effects the strength of a bag:

Below is our results table, along with our predictions (we didn’t time it). As you can see, the majority of the people thought JD Sports would hold the most bricks and the second largest amount of people thought the “Tunisia” bag would succeed.

For key skills this week, have a think about the questions below, reply with a paragraph that covers at least two of the questions – if everyone has answered 1 and 2 for example, try and do the others on. We will be using all of the answers as a resource for discussion next week.

1) Why do you think those two bags were the most successful?

2) How could we have made the test more fair?

3) How could we have improved the test?

4) How else could we have tested the strength of plastic bags?

5) What made the test unfair?

6) Do you think our results were accurate and reliable, and why?

7) What other questions could we ask following the investigation?

Remember, we tried our hardest to make it as fair as possible! 

 

Maths Key Skills: 

This week we have been improving our use of the four operations!

Your key skills for this week is the following questions:

Addition:

1)4.1 + 9.23 =

2)81.2 + 91.3 =

3)218 + 673 =

4)132.8 + 48.2 =

Subtraction:

1)38.1 – 13.4 =

2)92.78 – 13.23 =

3)123.11 – 62.10 =

4)48.44 – 32.15 =

Division:

1)84 ÷ 4 =

2)78  ÷ 3 =

3)612  ÷ 6 =

4)555  ÷ 5 =

Multiplication:

1)32 x 19 =

2)72 x 38 =

3)22 x 67 =

4)31 x 52 =

Complete them in your key skills book.

Have a fantastic weekend!

  1. 1) I think that the two bags that won , won because they where designed to carry heavy things.

    2) we could of made the test more fair by putting the same shape and weight of the bricks in the bags.

    3) we could improve the test by doing it precisely, by weighing the bricks to make the test more fair.

    4)we could of tested the strength of the bag by putting litre bottles of liquid in them.

    5) the weight of the bricks made the test unfair because you put different bricks in each bag so one bag could have the heaviest bricks in and the other ones could have the bricks that are not so heavy.

    6) no I don’t think the results are accurate because it was an unfair test.

    7) we could ask the following questions :
    1) which bag did you vote for and why?
    2)if you had to do the investigation again what would you do different and why?
    3)what other plastic bags would you want to test and why?

  2. I think the test is unfair because every time the bricks fell onto the floor they broke a bit more every time. When I voted for the JD bag I did not think that the handles would keep stretching like that . I did not know the Tunisia bag would hold 13 bricks! I thought it would hold something more like 10 bricks maybe? The Tesco bag 1 and 2 surprised me a lot that they could hold 8 and 7 bricks! Wow! I personally think we should of hung it from a higher place than that broomstick from the table. It should have been somewhere like a tree branch in the wooded area in the field. We should of had some more bricks just to make sure of that we had enough bricks to replace the broken bricks.

    1-I think the two bags that won,won because they were made or designed to carry heavy things.
    2- We could have made the test more fair by using the exact same bricks because we use the odd 1or 2.
    3-We could have improved the test by making sure that the bricks weighed the same.
    4-We could have tested weight of the bags by putting cans in them.
    5- Not all the bricks were the same weight (mabye) so some of the bags could have had the heavier bricks in and another one not
    6-The results are unfair because the test was not accurate.
    7-we could ask the following
    Was it actual a fair test
    Did everyone agree with the choice of items used
    Were the bricks the same weight
    We’re the results accurate
    Thank you for reading 🙂 🙂

  4. Why do you think the two bags were the most successful?

    Because the bags had stronger materials and

    the handles and the bottom of the bag were a lot more stable

    than the others.

    2) How could we have made the test more fair?

    We could have put the broom a bit higher

    so the bag didn’t touch the floor that made it stop and not snap.

    3) How could we have improved the test?

    I think we could have had put the bricks in a different position and there could

    be a bigger range of bags.

    4) How else could we had tested the strength of the plastic bags?

    I think we could have played tug of war with them.

    5) What made the test unfair?

    I think when you take the bag off the broom without it breaking.

    6.) Do you think the test results were accurate, and why?

    I think they were, because the Tesco bags were surprising, but so was the Tunisia bag.

  5. I think the two bags that have won, won because they are very good at designed to hold very hevey stuff and the JD one every one we’ll I think every one voted for it because it looked like it would hold a lot of stuff so in that case bricks. I was not there for most of it but my friends have told me every think and thank you for telling me 🙂

  6. 1) Why do you think those two bags were the most successful? Answer: I think those two bags won, because both of the shops for the bags sell heavy things. They were designed for heavy thing (bricks, not literally) so they won.
    2) How could we have made the test more fair (fairer Mr Prosser)? Answer: To make the test fairer we should have weighed the bricks, and made sure they were the same weight.
    3) How could we have improved the test? Answer: I can only think of making it fairer and placing the bricks at the same angle.
    4) How else could we have tested the strength of plastic bags? Answer: We could have got two people (always the same) to stretch the bags and measured how far the pulled before it broke.
    5) What made the test unfair? Answer: We didn’t see if the bricks were the same, we didn’t leave the bags much room to stretch (they hit the floor).
    6) Do you think our results were accurate and reliable, and why? Answer: I don’t think the results of the test were accurate, because for the JD bag it stretched to the floor. It didn’t finish stretching before we put another brick in. also I thought the Tunisia bag got 14 not 13!
    7) What other questions could we ask following the investigation? Final Answer:
    • DID YOU VOTE FOR ONE OF THE WINNING BAGS?
    • WHY DID YOU VOTE FOR THAT BAG?
    • WHAT WOULD YOU HAVE DONE TO MAKE IT BETTER?
    • WHAT ELSE COULD WE HAVE USED INSTEAD OF BRICKS?
    • WHAT ELSE COULD WE HAVE USED INSTEAD OF PLASTIC BAGS?
    Here is my description of the investigation:

    I really enjoyed our experiment. I think it was a very fair and fun test, and I would love to do it again. When we passed the bags around, I didn’t think that JD would be one of the winners. It was so funny when the JD bag’s handles stretched really long (It really did look like a handbag). My favorite part of the experiment was when all the bricks piled on top of the broom for the Tunisia Bag.

  7. I think the JD bag and the Tunisia bag were the strongest Beacause they are both desighned for heavier objects. To tell the truth i did not think that the Tesco bag is that strong. In my opinion I though that the tesco bag would hold no more than two bricks.
    I think we could of made the test more fair, if all of the bricks were the same size , due to the fact that the bags that weren’ t that strong may of had the heavier bricks put in them.

  8. I think TUNISIA ! and JD won because their material was the same the material was both strong thick plastic. Most people voted for the JD bag because it was the biggest and i personally think the blackness of the bag made it look strong.

    /i hope you could understand my spellings

    🙂

  9. I think that the two bags that won,were the winners because of the way they were made (hard, elastic material) and for what they were made (duty-free bag – for bottles of wine, loads of that kind)

    I think that we could of made the test fairer if the small bags were filled with bricks on the same height as the ( reaching the floor ) big bags because it would make it same.

  10. 1) I think the two bags won because of the material and the desine
    2) I think the test would be fairer if we made sure that the bricks were the same size
    3) We could improve the test by making sure the bricks weighed the same and from the same place
    4) We could of put shoes in there
    5) The handles made it unfair like the Tunisia bag had built in handles but the Next bag had attached handles
    6) I think that the results were fair because each bag had a plun and a weak spot like Tesco had a thinner plastic then JD
    7) Q’s :
    DID WE ENJOY THE TEST?
    WHAT COULD WE CHANGE ABOUT THE TEST?
    WHAT INFO DID WE GET FROM THE TEST?
    DID ANY UNECSPEKTED THINGS HAPPEN ?
    WHAT DID WE KNOW THAT WAS GOING TO HAPPEN?
    WHAT BAGS COULD WE HAVE USED?
